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： 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 With the fixation element positioned as desired, the sheath is withdrawn to permit the fixation element to self-expand against body tissue, thus to secure the fixation element and catheter.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 dilation 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, dependeing upon the particular treatment and the expected duration of fixation. Another approach employs a recovery metal in the fixation element.

摘要： A unitary, inflatable penile prosthesis system includes a prosthesis implantable within the corpus cavernosum of the penis in order to alleviate erectile impotency. A tubular enclosure includes a distal pump, a medial pressurizable chamber, and a proximal fluid reservoir. A pump draws fluid from the reservoir through an external fluid passageway into the pressurizable chamber. The pressurizable chamber is defined by an internal, tubular, substantially nondistensible portion and a concentric tubular sleeve. The nondistensible portion is crimped so that it may expand in diameter. Upon expansion, the prosthesis assumes a straight, erect state. The sleeve may elastically bias the nondistensible portion to its flaccid state. Fluid for filling the nondistensible portion may be stored in a rear fluid reservoir having a rigid internal stabilizer.
