摘要： A catheter assembly includes a catheter, a tubular structure affixed to an exterior surface of the catheter, and a stabilizing cuff affixed to, and at least partially embedded within, the tubular structure. The tubular structure may include a tapered surface extending from an end of the tubular structure to an exterior surface of the catheter. A method of manufacturing a catheter assembly may include positioning a tubular structure about a catheter, positioning a stabilizing cuff near the tubular structure, and partially embedding at least a portion of the stabilizing cuff within the tubular structure while shaping the tubular structure to form a tapered surface. A temporary sleeve may be positioned about the tubular structure prior to shaping the tubular structure. The tubular structure may also be preformed to include a tapered end prior to positioning the tubular structure about the catheter.

摘要： A septum for use in sealably covering a fluid cavity of an implantable medical device, such as an access port, is disclosed. The septum is resilient and includes a reinforcement structure that bolsters septum placement over the fluid cavity so as to inhibit unintended separation of the septum from the medical device when the fluid cavity is under pressure, such as during power injection of fluid into the fluid cavity. In one embodiment the septum comprises a resilient septum body that includes a flange disposed about a perimeter thereof. A reinforcement component is disposed in the flange for reinforcing engagement of the flange with a corresponding groove defined about an opening to the fluid cavity of the medical device so as to inhibit unintended detachment of the septum from the medical device. The reinforcement component in one embodiment includes an annular cord disposed in the flange.
