Devices, systems, and methods for prosthesis delivery and implantation

Abstract

Devices, systems, and methods use a catheter device sized and configured for introduction to a targeted site in a hollow body organ or blood vessel. The catheter device includes a first release mechanisms coupled to the prosthesis to secure at least one region of the prosthesis to the catheter shaft, and a second release mechanism coupled to the prosthesis in cooperation with the first release mechanism to prevent full release of the at least one region of the at least one region of the prosthesis from the catheter shaft after actuation of the first release mechanism. A fastening device sized and configured for introduction to the targeted site in the hollow body organ or blood vessel occupied by the catheter device, includes an actuator to deploy a fastener in the at least one region of the prosthesis after actuation of the first release mechanism and before actuation of the second release mechanism.

AI Technical Summary

Benefits of technology

[0011]The devices, systems, and methods make possible longitudinal and / or rotational adjustment of the position and orientation of the prosthesis before prior to applying a fastener. The devices, systems, and methods also make possible retaining control of the prosthesis, both proximally and distally, while a fastener is applied.

Problems solved by technology

The weakening of a vessel wall from damage or disease can lead to vessel dilatation and the formation of an aneurysm.

Left untreated, an aneurysm can grow in size and may eventually rupture.

The rupture of an aortic aneurysm results in massive hemorrhaging and has a high rate of mortality.

The prosthetic prosthesis for these procedures are usually unsupported woven tubes and are typically made from polyester, ePTFE or other suitable materials.

However, these procedures require a large surgical incision and have a high rate of morbidity and mortality.

In addition, many patients are unsuitable for this type of major surgery due to other co-morbidities.
