Bolton Medical has completed patient enrolment in a Phase I trial designed to evaluate the safety and efficacy of the Treovance abdominal stent-graft with the Navitel delivery system in the endovascular aortic repair of abdominal aortic aneurysms.

The Trevoance abdominal stent-graft offers advantages through its size-range and multiple fixation points, while the Navitel delivery system is equipped with a detachable sheath that allows for controlled or rapid deployment.

The Phase I trial includes 30 patients at six centres across the US.

The company plans to conduct a pivotal Phase II trial in 2012.
