AI Technical Summary

Technical Problem

Existing inflatable balloons and covers used in interventional medical procedures face challenges with high inflation pressures and non-uniform deployment of expandable implants, such as stents or stent-grafts, which can lead to inefficiencies and potential complications.

Method used

The development of a medical balloon with a continuously wrapped outer cover comprising an innermost porous polymer layer and an absorbent elastomer component, featuring pleats along its longitudinal axis, which allows for reduced inflation pressures and more uniform deployment of expandable implants.

Benefits of technology

The solution achieves lower inflation pressures and improved uniformity in the deployment of expandable implants, enhancing the efficacy and safety of medical procedures by facilitating controlled expansion and attachment to the treatment site.

Abstract

To provide implantable medical devices comprising covers, such as a balloon cover (106).SOLUTION: Such devices can comprise a first layer of a porous polymeric material (312), such as ePTFE, surrounded by layers of a porous polymeric material (316) having an imbibed elastomer such as polyurethane. The cover can be used to assist in deployment of an expandable implant, such as a stent-graft, within the body of a patient.SELECTED DRAWING: None
