Patent attributes
A catheter retention assembly and method of use with a catheter. The assembly has a carrier system and a cuff positioning device with an in-growth cuff and a lumen having an inner wall adapted to be mounted on the outer surface of the catheter, and a carrier system with an inner surface and an outer surface in contact with the inner wall of the cuff positioning device. The carrier system holds the lumen in a first radial state. When the carrier system is removed, the lumen contracts to a second radial state, and the inner wall of the cuff positioning device provides sufficient surface adherence to the outer surface of the catheter, so as to maintain the position of the cuff positioning device relative to the catheter, and to allow for catheter exchange.
