Patent Images
1. An occlusion device comprising:
- first and second fixation devices;
a center extending between the first and second fixation devices, wherein the center comprises a hollow member and a channel through a wall of the hollow member defining a plurality of interlocking portions shaped to allow flexing of the center without axial disconnection of the interlocking portions; and
a tether extending through the hollow member, the tether being connected at a first end to the first taxation device and connected at a second end to the second fixation device.

Abstract
This invention relates to a center connection having a flexible section. The flexible section allows a portion of the center connection to be highly flexible, while maintaining the ability to transmit torque. One method of forming the flexible center connection is to form the flexible section of the center connection of a series of individual interlocked segments.
