Thank you, Tripp, and good afternoon and thank you everyone for joining us today to discuss the results of our very active second quarter of 2026. I would like to begin with a discussion of the amazing and novel technology that sits at the core of everything we do at Pulse Biosciences. are proprietary nanosecond pulse field ablation or NSPFA technology. By delivering electric pulses in only billionths of a second durations paired with high energy, we are able to treat tissue non-thermally and with exceptional effectiveness. This translates into tangible and measurable advantages across a range of different diseases and tissues in the human body. NSPFA produces targeted energy, non-thermal ablations, durable lesions, quicker ablation times, and faster procedure times, all complementing the natural body function of regulated cell death. This mechanism is uniquely stimulated by NSPFA and is unmatched by existing ablation energies, including all prior art and the broad category of microsecond PFA alternatives. Underpinning the platform are a uniquely experienced technology development team which has produced the highly novel NSPFA system and a deep patent estate of more than 250 issued patents worldwide. Together, this team, a number of whom have worked together for over a decade and patent moat, are fundamental to protecting and amplifying our long-term leadership in this field. Last quarter, we announced a strategic alignment to prioritize, accelerate, and broaden the development of our end pulse cardiac catheter ablation system. Our focus remains concentrated on the treatment of atrial fibrillation and the development of our end pulse cardiac catheter systems, while we continue to advance our surgical clamp and thyroid programs with discipline and optimism. As part of our strategic alignment, we focused on two key pillars in our program, generating compelling clinical data and executing rapid trial enrollment across a growing base of studies. During the second quarter, with this shift in focus, We have delivered positive and important achievements in our cardiac catheter program. We enrolled the first patient in our pivotal catheter IDE study, including seven cases on day one. We activated multiple sites, presented outstanding feasibility data at the Heart Rhythm Society meeting in April, and further strengthened our leadership team with the additions of Liane Teplitsky as Chief Operating Officer and Dr. David Kenigsberg as full-time chief medical officer. These two leaders have strengthened our ability to execute a successful pivotal IDE study and advance toward regulatory approvals. We also meaningfully bolstered our balance sheet, now with over $100 million on hand, expanding our runway to fund development and clinical milestones ahead. Thank you for joining us. This strengthened our balance sheet during the quarter and reflects growing and expanding conviction in the NSPFA platform and the growth opportunities in front of us. This is a complex environment for raising capital and we are proud that investors who took a close look at our technical and clinical progress were able to appreciate the value creation story we are building at Pulse Biosciences. Additionally, We recently announced that we have surpassed the halfway point of enrollment in our U.S. pivotal capita study. Ahead of our original schedule and on the strength of that pace, we are confident in completing enrollment on our accelerated timeline of early Q4. Reaching this point so quickly in a pivotal AFib study is extraordinary, and we attribute it partly to a straightforward dynamic. Physicians are thrilled by their personal NSPFA clinical experience when using this catheter and are highly enthusiastic to both expand their use and share their positive experiences with their peers. This response is universal across operators. Today, I will focus most of my remarks on the catheter and then we'll provide updates on our two other NSPFA devices. We will then turn the call over to our Chief Financial Officer, Jon Skinner, to review the second quarter financial results in detail. We will then conclude with a question and answer session joined by Bob Duggan, Co-Chair of the Board. I will now discuss the NPulse cardiac catheter system for AF ablation. Earlier in July, we shared that the Nanopulse AF study crossed its enrollment midpoint with more than 82 evaluable patients. Net of Roll-ins, treated in the IDE since the study began enrolling in April. The PACE exceeds all expectations and reflects investigational site enthusiasm for what NSPFA technology offers. Durable pulmonary vein isolation, familiar and rapid workflow, intuitive user experience, an efficient procedure, and consistently positive outcomes for patients in need of AFib resolution. We are proud of current results and rest assured we are persistent in striving to do even better. Given our enrollment cadence thus far and expectations for site performance in the second half of the study, we are confirming our target completion date of early October three months earlier than our original timeline. This enrollment velocity reflects the quality of our investigational sites along with their lab and clinical research staffs and the compelling clinical attributes of our catheter and energy system. Physicians comment that the system is extremely intuitive with a straightforward learning curve as well as seamless workflow integration translating directly to rapid, efficient procedure and ablation times. We have seen multiple sites perform five and up to seven cases in a day and multiple physicians have completed their initial cases with seven to eight minutes or faster ablation times. With other ablation catheters currently available, EP labs generally do not schedule more than two to three cases per day. This early on meaningful expansion of daily case capacity is the best evidence of the workflow and procedure speed advantages as well as potential hospital economies that will follow as they utilize the NPulse system. Catheters that change practice patterns for the better, and dramatically so, in our view, will become a compelling and welcomed option for electrophysiologists and hospitals. Upon the basis of workflow efficiencies, patient outcomes, and more, our NSPFA console and catheters continue to demonstrate unprecedented potential to transform the treatment landscape for atrial fibrillation. We chose to amend our nanopulse AF pivotal study protocol to increase the total enrollment target by 19 patients from a target of 145 to a new target of 164. This is being done in concert with reducing prior enrollment restrictions on the types of antiarrhythmic drugs or AADs A patient must fail in order to qualify for inclusion. Now, patients that have failed any one of the four classes of AADs may qualify for the study. We believe this protocol modification better reflects contemporary clinical practice and real-world patient management. This protocol change also expands the pool of qualifying patients. We are pleased to confirm that full study enrollment is still expected to be completed by our revised date of early October, even with the increase in study size. Site activation continues to proceed well, and the momentum across our investigational network is being maintained as we expanded the base of active study sites to 12, and this number is expanding in real time. While the study protocol allows for enrollment at up to 30 sites, we do not anticipate activating all 30 due to the physician enthusiasm and enrollment velocity we have already experienced in the current base as sites and investigators are activated. Diving further into our study protocol, our efficacy endpoint, freedom from treatment failure through 12 months, incorporates a mix of both 12-month and 6-month patient follow-up data. The blended endpoint optimizes overall follow-up time for the study while supporting statistical rigor. As a reminder of our data presented at Heart Rhythm Society, or HRS, Dr. Vivek Reddy, the National Principal Investigator for our pivotal study, shared expanded results from our European NPulse cardiac catheter feasibility study, including 6-month follow-up Thank you for joining us. Estimated freedom from recurrent AF, flutter, or tachycardia at one year alongside a serious adverse event rate of just 1.7% across 177 patients. Those numbers compare quite favorably to the meaningfully lower success rates typically seen with other ablation technologies. and were achieved without antiarrhythmic drugs and with consistent performance across operators and sites. The EU feasibility data continue to support our path toward a CE mark submission in the second half of this year, and we see a potential CE approval around the middle of 2027, roughly six months post submission. Supporting our go-to-market strategy with the EP catheter, We are continuing to pursue a partnership strategy. Our dialogue with prospective partners is ongoing, centered around the established players in electrophysiology with available mapping technologies. Those conversations are underway, and we'll provide details when appropriate. Let's now move to our surgical clamp program, where treatments in our pivotal IDE clinical study continue to perform well. Concomitant ablation for pre-existing AF is, in our view, significantly underpenetrated, and we believe nanosecond PFA can support increased surgeon adoption and drive meaningful market penetration over time. Currently, available tools provide inconsistent results with involved and time-consuming procedure protocols. Our clamp was designed to address these needs efficiently, and to deliver the speed and effectiveness of NSPFA technology, which is capable of delivering reproducible transmural lesions nearly instantaneously, producing a more reliable and trusted ablation procedure, all for the purpose of improved patient outcomes. In addition to our IDE enrollment, our EU feasibility study has now treated more than 70 patients across six sites. Three-month post-procedure electroanatomical mapping results were presented at the European Heart Rhythm Association 2026 meeting and demonstrated excellent lesion durability and procedural efficacy on 34 patients. Total ablation time averaged just 41 seconds per patient, and pulmonary vein isolation success held steady Thank you for joining us. In the U.S., our pivotal study, NanoClamp AF, continues to enroll. As a reminder, it remains the only trial of a PFA surgical device to have secured FDA IDE approval. The IDE is a prospective single-arm study spanning 20 centers, three of them international, with a target of 136 patients designed to Thank you for joining us today. Thank you for joining us. Thank you for joining us. We are proud to announce a new partnership with the Klayman Thyroid Center in Tampa, Florida, the largest thyroid surgery center in the United States. This unique partnership is focused on supporting our core strategy of demonstrating the viability of the Vibrant System therapy for patients with symptomatic benign thyroid nodules. Key elements of this partnership will include registry data generation and unique study protocols for interventional therapy in thyroid disease. Bringing on a center of this caliber is an important step toward our goal of establishing NSPFA as a minimally invasive standard of care for benign thyroid nodules. Over the past several weeks, the Klayman Center has onboarded the vibrant system and performed its first cases and we look forward to reporting on progress toward our partnership objectives in future quarters. Additionally, our precise BTN benign thyroid nodule study continues to proceed quickly and we expect the study to be fully enrolled this month. We broadened the study from its original 50 patient design to 100 patients to deepen the data set in support of adoption and long-term market expansion. Scientific recognition of this work continues to grow. Data from Dr. Stefano Speazia in Naples, Italy was recently presented in a podium session at the North American Society of Interventional Thyroidology, or NASIT. The data showed durable results out to 15 to 22 months. A 74% reduction in treated nodule volume, as per our expectations, alongside overwhelming patient satisfaction featuring very rapid symptoms relief post-treatment. Volume reduction continued to improve from one month all the way through 22 months with no nodule regrowth observed in the 15 to 22 month time frame. Beyond precise BTN, we are also widening the clinical scope of our Vibrance platforms. Through our research collaboration with the University of Texas MD Anderson Cancer Center, researchers at two study centers are conducting a multi-center, first-in-human feasibility study of NSPFA for papillary thyroid microcarcinoma, or PTMC. This study is designed to enroll up to 30 patients across two sites. I'm pleased to announce that this study is approximately half-enrolled. and we expect to complete enrollment by year-end 2026. And looking ahead, we've begun planning additional clinical trials with the aim of extending the Vibrance platform into new thyroid indications as we support our plans to bring this revolutionary therapy to a broader patient population. With that, I'll turn the call over to Jon to walk through our second quarter financial results.
