Balloon endoscopy allows physicians to access the bowel for evaluating and treating obscure bleeding, small bowel tumors, obstructions, and more. However, the balloons currently used in these procedures have a very low coefficient of friction, especially against the soft, mucus-covered wall of the gastrointestinal (GI) tract. This low friction regularly leads to balloon slippage, which impedes advancement of the endoscope and greatly increases the procedure time and discomfort for the patient. Every year in the United States, over 51.5 million gastrointestinal endoscopies are performed. Physicians at all levels of care, from teaching and low-income hospitals to private endoscopy centers, are using these conventional smooth balloons in endoscopy procedures, and all are in need of improved, high-traction technology. Aspero Medical aims to fill this need by developing a patented, micro-textured balloon technology through biomimicry of micro-patterns found on the feet of terrestrial animals. By fabricating endoscopy balloons with these naturally occurring micro-patterns, the company has shown that it is possible to improve the frictional properties of endoscopy balloons. The work described in this proposal is separated into three tasks. In Task 1, the micro-textured balloon design will be optimized for high performance and cost-effective manufacturing. In Task 2, the investigators will test the hypothesis that using a micro-textured balloon will prove more effective than conventional smooth balloons in double-balloon endoscopy procedures across a range of metrics. In Task 3, the investigators will get critical user feedback from a highly experienced gastroenterologist regarding the performance of the balloons in human tissue. The Investigative Team, composed of surgical medical device engineers and experienced gastroenterologists, is uniquely positioned to guarantee the success of this proposed research. Specifically, the Investigators collectively possess substantial expertise in medical and surgical device design and gastroenterology. If successful, this technological improvement will minimize wasted procedure time, allow physicians to efficiently complete the prescribed procedures without complication, increase the number of successful small bowel diagnoses, and result in cost savings and reduced discomfort for the patient.

Public Health Relevance Statement:
NARRATIVE Over 51.5 million gastrointestinal endoscopies are performed annually in the United States. Many of these procedures are riddled with balloon slippage events that increase procedure time and can often lead to scheduling additional, and sometimes more-invasive, procedures. The success of this study will save time, save money, and improve patient outcomes compared to current practices.

Aspero Medical has developed a micro-textured balloon with reduced slippage for use with all standard endoscopes for gastrointestinal endoscopy. The currently used smooth balloons are prone to slippage that reduces the success rate of endoscopic procedures, which increases the number of procedures and contributes an estimated $100-300 million in excess costs for patients and insurers each year. In a Phase I SBIR (1R43DK126504), Aspero optimized the balloon design for performance and scalability. The company subsequently finalized manufacturing controls, completed an FDA 510(k) pre-submission meeting, and prepared a 510(k) application for FDA review. In consultation with clinical advisors, other clinicians, and key opinion leaders in the field, Aspero determined that successful adoption of the device (Aspero Ancora)-and the resulting beneficial impact on procedure success rate and patient costs-will require clinical evidence of superiority compared to well-known, established devices that are already on the market. Therefore, in this Phase II application, Aspero proposes a multi-site, randomized, double-masked clinical study to establish the superiority of Aspero Ancora vs. the Olympus ST-SB1. The study will compare procedure success rates in the middle third of the small bowel. Success rates in this portion of the bowel with current devices, including the Olympus overtube, are estimated to be about 50%. Market research indicates clinicians would consider an increase from 50% to 60% to be clinically valuable and sufficient grounds for switching to a new device. However, based on the performance of Ancora in animal studies, Aspero anticipates a success rate of at least 75%, and the proposed study is powered based on this expectation. Notably, the proposed study would be the first comparative balloon study in which the clinician is masked to the identity of the device. Aim. Demonstrate superiority of the Aspero Ancora balloon overtube compared to the Olympus ST-SB1 balloon overtube. The study will include 110 consenting patients with lesions in the middle third of the small bowel (previously confirmed by video capsule endoscopy). These individuals will be randomized to receive enteroscopy with the Ancora or ST-SB1 balloon overtube, which will be orally inserted and removed by a study assistant to mask the surgeon to the device identity. The primary outcome of interest is success in identifying the lesion, which indicates sufficient balloon control to reach and visualize the site. Superiority of the Ancora balloon overtube will be demonstrated if it achieves a success rate of 75% compared to a success rate of 50% with the Olympus ST-SB1 balloon overtube. Impact-Demonstration of superiority of Aspero Ancora is necessary for adoption by clinicians. Broad adoption is expected to improve procedure success rates, reduce time to diagnosis or treatment (thereby, improving patient outcomes), and reduce the burden and costs of care for patients, providers, and insurers.

Public Health Relevance Statement:
PROJECT NARRATIVE Devices currently used for gastrointestinal endoscopy use smooth inflatable balloons to hold the device in place during procedures in the bowel, and these smooth balloons contribute to slippage that increases procedure time, increases costs, and can prevent the operator from completing the procedure. This study is designed to demonstrate that a new type of balloon with a micro-textured surface reduces slippage and increases procedure success rates. The study is expected to support broad adoption of this new type of balloon, which is expected to reduce the time needed to diagnose and treat patients, resulting in lower healthcare costs and better patient outcomes.
