Abstract
This invention relates to methods and apparatus for making and using noded cuffs on transcutaneous or intrabody prosthetic devices, such as catheters, to effect improved stability of the prosthesis/tissue opening site interface. In particular, the noded cuff apparatus of the present invention provides for positioning of the tissue opening site in a manner which facilitates more rapid establishment of a stably biointegrated and well-healed prosthesis/tissue opening site interface. In addition, in accord with the methods of the present invention, non-biointegrated portions of the noded cuff can be simply and easily removed from the underlying prosthetic device to facilitate maintenance of the stably biointegrated interface. Preferably, this removal takes place after a period of time during which the interface has become stably established. In accord with the methods and apparatus of the present invention, thus, infections or healing difficulties at the prosthesis/tissue opening site interface are greatly reduced and a more comfortable and stable interface is more rapidly established and more easily maintained.
