Magnetic anastomosis device having improved delivery
First Claim
1. A magnet assembly for a magnetic anastamosis device used for forming an anastamosis between two bodily walls, the magnet assembly comprising:
- an elongated hub having a proximal end and a distal end, the elongated hub being tubular and defining an inner passageway sized to receive a wire guide; and
a plurality of magnetic members disposed over the elongated hub;
the magnet assembly operable between a delivery configuration and a deployed configuration, the elongated hub extending generally linearly in the delivery configuration, the elongated hub forming an annular shape in the deployed configuration where the proximal end and the distal end of the elongated hub are adjacent to each other.

Abstract
A magnet assembly for a magnetic anastamosis device is provide that is minimally invasive, easily and quickly delivered, and is accurately positioned to improve the delivery procedure. The magnet assembly includes an elongated hub and a plurality of magnetic members disposed over the elongated hub. The elongated hub is formed of a resilient or shape memory material, permitting the magnet assembly to be operable between a delivery configuration and a deployed configuration. In this manner, the package width of the magnet assembly is greatly reduced for delivery, thereby permitting delivery over a wire guide as well as through an access device such as a catheter. Associated delivery procedures and medical devices are also provided.

12. A medical device for use in forming an anastamosis between two bodily walls, the medical device comprising:
-
a magnet assembly having an elongated hub having a proximal end and a distal end and a plurality of magnetic members disposed over the elongated hub; and an access device structured to be coupled to the magnet assembly, the access device comprising a wire guide; wherein the elongated hub includes a passageway sized to receive the wire guide therein; the magnet assembly assuming a delivery configuration when the magnet assembly is coupled to the access device, the delivery configuration having a generally linear shape; the magnet assembly assuming a deployed configuration when the magnet assembly is decoupled from the access device, the deployed configuration having a generally annular shape where the proximal end and the distal end of the elongated hub are adjacent to each other. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
