摘要： A penile prosthesis system involves the use of an inflatable penile prosthesis which is expandable under pressurization from a flaccid to an erect state. The prosthesis exhibits a low modulus of elasticity in expansion but ultimately reaches a modulus transition after which it exhibits a high modulus of elasticity and resists further expansion. The prosthesis may also be formed of a material which elastically expands from a flaccid to an erect state and elastically contracts thereafter. In its erect state the prosthesis is taut and the surrounding tissue may be similarly taut and pressurized because of the expansion of the prosthesis in girth. If a weakening occurs in the surrounding tissue, the tendancy to form localized penile bulges is limited because of the inability of the prostheis to expand readily beyond its modulus transition.
摘要翻译：阴茎假体系统涉及使用可膨胀的阴茎假体，其在从松弛状态到直立状态的加压下可膨胀。假体在膨胀中表现出低的弹性模量，但是最终达到模量转变，之后其显示出高的弹性模量并且抵抗进一步的膨胀。假体也可以由弹性膨胀从松弛状态到直立状态的材料形成，然后弹性收缩。在其直立状态下，由于假体在周长中的膨胀，假体被拉紧并且周围的组织可以类似地拉紧和加压。如果在周围组织中发生弱化，则形成局部阴茎隆起的倾向是有限的，因为假肢不能容易地膨胀超过其模量转变。

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： 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： 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： 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.
