PROVIDENCE, R.I. (September 3, 2025) — Brown Surgical Associates is proud to announce that Dr. Jeffery Slaiby and Dr. Peter Soden recently became the first surgeons in New England to implant the newly FDA-approved Zenith® Iliac Branch Device (ZBIS). The procedure took place on July 29, 2025, at Rhode Island Hospital, marking a major step forward in treating patients with aortoiliac and iliac aneurysms.
The device, which gained FDA approval in May of this year, is built on Cook Medical’s proven Zenith platform and is designed to offer a safer, minimally invasive option for patients with these life-threatening conditions. The ZBIS graft not only repairs aneurysms but also preserves blood flow to the internal iliac artery—helping reduce risks like pain, sexual dysfunction, and other complications.
“This device expands treatment options for patients who previously might not have been candidates for minimally invasive repair,” said Dr. Slaiby. “It’s exciting to bring this technology to Rhode Island and be the first in New England to perform this life-changing surgery.”
Dr. Soden added: “The ability to treat aneurysms while preserving blood flow is a significant advancement. We’re proud to offer our patients the latest in innovative vascular care right here at Rhode Island Hospital.”
Clinical trial data show strong long-term outcomes, including durable aneurysm repair and 97% of patients free from buttock claudication at five years. Cook Medical has described the launch of ZBIS as an important addition to its aortic device portfolio, expanding treatment options and improving patient outcomes.
