摘要： A medical apparatus and method of use for implanting a catheter in a patient's body which catheter can be easily positioned, repositioned, and replaced. The apparatus includes an elongate sleeve intended to be subcutaneously implanted. The sleeve comprises a wall surrounding an interior elongate passageway which extends from a sleeve proximal end to a sleeve distal end. The sleeve outer peripheral surface carries a layer of porous material intended to be placed just under the patient's outer skin layer in contact with the dermis to promote tissue ingrowth for anchoring the sleeve and forming an infection resistant barrier. The sleeve passageway includes a sealing nib dimensioned to engage the outer surface of the catheter while permitting the catheter to slide relative to the sleeve. The sealing nib prevents deleterious material from migrating into the patient's body along the catheter outer surface.

摘要： An implantable device (42) including a housing having a stud (62) projecting percutaneously through an incision in the patient's skin. The stud (62) defines a peripheral surface (66) extending longitudinally inwardly from the stud (62) outer end. The longitudinal peripheral surface (66) is used as a substrate to carry a peripheral fibrous layer (70) which extends longitudinally along the stud (62)from its outer end adjacent to the skin incision to below the patient's epidermal and dermal skin layers for promoting laterally directed soft tissue in growth. The housing (42) also defines a lateral shoulder surface (60) oriented substantially perpendicular to the longitudinal peripheral surface (66). The shoulder surface (60), when implanted, is located just inwardly from the patient's outer skin surface. The shoulder surface (60) also carries a porous layer conducive to promoting tissue in growth (72). The provision of both lateral and longitudinal porous layers on the device allows tissue in growth, i.e., tissue growth into the interstices of both porous layers to form an enhanced infection resistant barrier while also providing improved device anchoring.

摘要： A method and apparatus for facilitating the management of indwelling conduits to avoid and/or treat infections associated with long term implantation. A sleeve carrying a layer of porous material on its outer surface is percutaneous implanted to place the layer of porous material just under the patient's outer skin in contact with the patient's dermis where it functions to promote soft tissue ingrowth. A catheter passes through the sleeve passageway and along an interior body path to an interior destination site, e.g., an opening into a vein, i.e., venotomy site. Within about 3-6 weeks after implantation, the patient's dermal tissue integrates sufficiently with the sleeve porous material to physically anchor the sleeve and create an infection resistant barrier. Further, a tunnel, characterized by an epithelialized capsule, typically forms around the catheter along the interior body path extending to the interior destination site. After sufficient integration of the patient's soft tissue into the porous layer, the sleeve passageway can be used to pass various procedural tools to the tunnel and interior destination site without disturbing the tissue integrating barrier.

摘要： A medical apparatus and method of use for implanting a percutaneous catheter in a patient's body which includes an elongate sleeve comprising a wall surrounding an interior elongate passageway. The sleeve is intended to be percutaneously implanted through an incision in the patients skin so that the sleeve distal end resides subcutaneously. The sleeve outer peripheral surface carries a layer of porous material intended to be placed just under the patient's outer skin layer in contact with the dermis to promote tissue ingrowth for anchoring the sleeve and forming an infection resistant barrier. The sleeve passageway is dimensioned to snugly accommodate the outer surface of catheter while permitting the catheter to slide relative to the sleeve. A sealing device is mounted around the catheter adjacent to the sleeve proximal end to prevent deleterious material from migrating into the patient's body along the catheter outer surface.
