摘要： An implantable penile prosthesis for overcoming male erectile impotence in the form of an elongated cylindrical device of malleable construction. The device is adapted to be implanted within the corpora cavernosa of the penis. A malleable rod capable of holding any shape to which it is bent is encapsulated within a cylindrical insert member made of biocompatible, flexible material. A thin walled sleeve of predetermined wall thickness may be positioned over the outside of the cylindrical insert member in covering relation thereto for adjustment of the outside diameter of the implant device. The cylindrical insert member tapers along its distal end section towards the distal end extremity of the device.

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.

摘要： A device is provided for maintaining a volume of gas dissolved in a fluid at a predetermined partial pressure. The device includes a first sealable, gas-tight pouch containing the fluid and a second sealable, gas-tight pouch encasing the first pouch and providing a space between the first and second pouches. The space may be charged with an atmosphere containing a volume of the gas dissolved in the fluid that is greater than the volume of dissolved gas, at a partial pressure that is substantially the same as the partial pressure of the dissolved gas. A method is also provided for using the device to maintain a volume of a gas dissolved in a fluid at a predetermined partial pressure.

摘要： An open weave fixation device is secured to a distal end region of a catheter or other diagnostic or treatment device, for either temporarily or permanently fixing the device within a body cavity. In one approach, the fixation element is constructed of braided, helically wound filaments of resilient stainless steel. A sheath surrounds the catheter and fixation element to elastically deform the element into a reduced radius configuration to facilitate insertion and deployment. With the fixation element positioned as desired, the sheath is withdrawn to permit the fixation element to self-expand against body tissue, thus to secure the fixation element and catheter. In an alternative arrangement, a dilatation balloon surrounds a catheter near its distal end, and in turn is surrounded by a plastically deformable fixation element. Following desired positioning, the balloon is dilated to permanently deform the fixation element into contact with body tissue. In either case, the fixation element can be mounted at its distal end, its proximal end or medially, depending upon the particular treatment and the expected duration of fixation. Another approach employs a recovery metal in the fixation element.

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： Methods and devices are disclosed for connecting implantable body fluid conduits, such as catheters and grafts for AV shunts. A connector with thin connector walls at the lumen openings provides a connecting lumen that is close to flush with the lumens of the attached conduits. A tapered, smooth walled connector lumen allows connection of conduits with different internal diameters while preserving laminar flow in the transition between different conduit diameters. Rounding of the connector edges at the lumen openings further reduce disturbances in flow.
