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 comprising a wall surrounding an interior passageway extending from a sleeve proximal end to a sleeve distal end. The sleeve is intended to be percutaneously implanted through an incision in the patient's skin to place the sleeve distal end subcutaneously. The sleeve distal end outer surface carries porous material intended to contact the patient's dermis to promote tissue ingrowth. The sleeve passageway is dimensioned to snugly accommodate the outer surface of the catheter while permitting the catheter to slide relative to the sleeve. A split ring locking member is selectively operable in an unlocked state for permitting axial and rotational movement of said catheter relative to said sleeve and operable in a locked state for preventing such relative movement.

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： 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 catheter can be easily positioned, repositioned, and replaced. The apparatus includes an elongate sleeve having a tapered forward portion to facilitate its insertion through an undersized incision. The sleeve provides an interior elongate passageway which extends from a sleeve proximal end to a sleeve distal end. The sleeve is intended to be percutaneously implanted through an incision in the patient's skin so that the sleeve distal end resides subcutaneously. The sleeve outer peripheral surface carries a layer of porous material intended to be placed 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. A locking member secured to the sleeve can be pivoted to an unlocked portion for permitting axial and rotational movement of said catheter relative to said sleeve and or to a locked position for preventing such relative movement.

摘要： An implantable device including a housing having a stud projecting percutaneously through an incision in the patient's skin. The stud defines a peripheral surface extending longitudinally inwardly from the stud outer end. The longitudinal peripheral surface is used as a substrate to carry a peripheral fibrous layer which extends longitudinally along the stud 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 ingrowth. The housing also defines a lateral shoulder surface oriented substantially perpendicular to the longitudinal peripheral surface. The shoulder surface also carries a porous layer conducive to promoting tissue ingrowth. The porous layers on the device allows tissue ingrowth into the interstices of both porous layers to form an enhanced infection resistant barrier while also providing improved device anchoring.

摘要： Vascular access systems for performing hemodialysis are disclosed. The vascular access system contemplates a catheter section adapted for insertion into a vein and a graft section adapted for attachment to an artery. The catheter section may have metal or polymer wall reinforcements that allow the use of thin-walled, small outer diameter conduits for the vascular access system. One or more of the adhered, embedded or bonded conduit reinforcement structures may be removable without significant damage to the conduit sections to facilitate attachment of the sections, or to a connector between the sections. Various self-sealing materials are provided for use in the vascular access system, as well as temporary access sites and flow control/sensor systems.

摘要： A method and system for the creation or modification of the wear surface of orthopedic joints, involving the preparation and use of one or more partially or fully preformed and procured components, adapted for insertion and placement into the body and at the joint site. In a preferred embodiment, component(s) can be partially cured and generally formed ex vivo and further and further formed in vivo at the joint site to enhance conformance and improve long term performance. In another embodiment, a preformed balloon or composite material can be inserted into the joint site and filled with a flowable biomaterial in situ to conform to the joint site. In yet another embodiment, the preformed component(s) can be fully cured and formed ex vivo and optionally further fitted and secured at the joint site. Preformed components can be sufficiently pliant to permit insertion through a minimally invasive portal, yet resilient enough to substantially assume, or tend towards, the desired form in vivo with additional forming there as needed.

摘要： A light delivery system for use in irradiating vascular tissue includes a balloon catheter with a working lumen for receiving an optical fiber therein and an inflation/flushing lumen adapted to receive a liquid at a proximal end and leading to a space defined within the balloon member attached to a distal end of the catheter. The balloon member has a pattern of holes or pores in the wall thereof through which the saline may flow when the balloon is inflated, causing any blood or other absorbing substances that may interfere with good radiant energy transmission to be flushed away from the treatment site.
