Devices and Methods for Treatment of Endovascular and Non-Endovascular Defects in Humans Using Occlusion Implants

摘要

Devices and methods are disclosed for occluding endovascular and non-endovascular defects, including parent artery occlusions, aneurysms and other abnormal openings in the body. The devices include one or more expandable braids that may be coupled to one or more helical coils suitable for introduction and retrieval from within a treatment area using a delivery catheter.

主权项

1. A system for occluding endovascular defects, comprising:
a tubular delivery catheter having a distal end and a proximal end; an elongate occlusion implant extending longitudinally within the delivery catheter, and configured to be pushed through and out of the delivery catheter and retrieved back into the distal end of the delivery catheter using a pushing member; wherein the occlusion implant at least partially expands to a larger volumetric area when pushed out of delivery catheter, wherein the occlusion implant comprises at least two elongate regions: a first region comprising an expandable tubular braid element and a second region comprising a non-expandable helical coil, wherein the expandable tubular braid is configured to have a pre-set expanded longitudinal shape when released from the delivery catheter; and wherein the occlusion implant traverses concomitant bends as the delivery catheter when delivered through the delivery catheter to the treatment location.
