Occlusion device with flexible wire connector
First Claim
Patent Images
1. An occlusion device comprising:
- a first occluding body including a first collapsible support frame;
a second occluding body including a second collapsible support frame;
a center assembly comprising a proximal hub attached to the first occluding body such that the first collapsible support frame extends through the proximal hub, a distal hub attached to the second occluding body such that the second collapsible support frame extends through the distal hub, and a flexible wire connector comprising a hollow multi-wire tube having a proximal end attached to the proximal hub and having a distal end attached to the distal hub; and
a safety tether having a proximal end attached to the proximal hub, a distal end attached to the distal hub, and central portion extending through a middle of the hollow multi-wire tube.

Abstract
An occlusion device includes a flexible section formed by a wire connector. The flexible wire connector gives the occlusion device improved torque and flexure characteristics, which allows the device to better conform to the contours of the heart.
