Abstract
An implantable medical device for connecting tissue layers, such as connecting tubular tissues to create an anastomosis, includes a single elongate member and a covering material. The devices provided may also be used for other purposes including, but not limited to, partially or fully occluding openings in tissue, temporarily or permanently holding generally planar layers of tissue together, aneurysm repair, and the like.
Claims23
A medical device for creating an anastomosis between a first body conduit and a second body conduit and configured to transition between contracted and expanded configurations, the device comprising:
- an elongate member defining a frame comprising:
- a first apposition portion and a second apposition portion;
- and
- a central portion disposed between the first apposition portion and the second apposition portion, the central portion defining a lumen therethrough and having a diameter and a length in the contracted configuration;
- and
- a covering material disposed on at least a portion of the central portion, the covering material being configured to allow material flow through the lumen and between the first body conduit and the second body conduit,
- wherein the frame is configured such that when transitioning from the contracted configuration to the expanded configuration, the length of the central portion is configured to increase by a greater amount relative to a reduction in the diameter of the central portion.

- an elongate member defining a frame comprising:
- a first apposition portion and a second apposition portion;
- and
- a central portion disposed between the first apposition portion and the second apposition portion, the central portion defining a lumen therethrough and having a diameter;
- and
- a covering material disposed on at least a portion of the central portion, the covering material being configured to allow material flow through the lumen and between the first body conduit and the second body conduit,
- wherein the central portion is configured such that the diameter of the central portion is substantially the same in the contracted configuration and in the expanded configuration.
