摘要:
A method and apparatus for a radially expandable stent for implantation within a body vessel, comprising a first and second wire having a series of alternating peaks and valleys. The valleys of the first wire are braided with the peaks of the second wire forming a braided region with the interwoven first and second wire being wound into a continuous helix having a hollow cylindrical shape. The peaks of the first wire of the continuous helix may be welded to the adjacent valleys of the second wire of the continuous helix. The peaks and valleys of the first wire may symmetrically intersect with the peaks and valleys of the second wire to form a uniform series of crossings thereby permitting even expansion of the first and second wires. The proximal end of the first wire may be attached to the proximal end of the second wire. The distal end of the first wire may be attached to the distal end of the second wire. A means within the interwoven first and second wires of the continuous helix may be included for expansion thereof.
摘要:
An apparatus and a method for opthalmic irrigation provide sterile, filtered irrigation fluid to the eye at high flow rates. The apparatus includes a filter capable of removing particulates on the order of 0.8 microns, and preferably as small as 0.22 microns. A distribution manifold is disclosed whereby fluid from a common reservoir may be routed sequentially to plural recipient sites.

An embolic filtering system includes a guide wire, a filter device disposed on the guide wire, a sheath adapted to maintain the filter device in an unexpanded position and a torque device having a lumen for receiving the guide wire and a locking mechanism for locking the torque device to the guide wire. The torque device may include a side port adapted to receive the proximal end of the sheath to allow a portion of the guide wire to shear the sheath from the guide wire through retraction of the sheath through the side port. The torque device may include an extension arm having a distal opening adapted to receive both the guide wire and the sheath. A second lumen may be used to allow a portion of the guide wire to shear the sheath away from the guide wire through retraction of the sheath through the second lumen.

摘要:
A novel polypeptide, osteoprotegerin binding protein, involved in osteolcast maturation has been identified based upon its affinity for osteoprotegerin. Nucleic acid sequences encoding the polypeptide, or a fragment, analog or derivative thereof, vectors and host cells for production, methods of preparing osteoprotegerin binding protein, and binding assays are also described. Compositions and methods for the treatment of bone diseases such as osteoporosis, bone loss due to arthritis or metastasis, hypercalcemia, and Paget's disease are also provided.

摘要:
The present invention discloses a novel secreted polypeptide, termed osteoprotegerin, which is a member of the tumor necrosis factor receptor superfamily and is involved in the regulation of bone metabolism. Also disclosed are nucleic acids encoding osteoprotegerin, polypeptides, recombinant vectors and host cells for expression, antibodies which bind OPG, and pharmaceutical compositions. The polypeptides are used to treat bone diseases characterized by increased resorption such as osteoporosis.
摘要:
This invention is directed to a diagnostic sheath device which is adapted to facilitate atraumatic navigation of intravascular catheters along vascular pathways. The sheath consists of an elongated flexible shaft, having a proximal end and a distal end. The distal end of the shaft is hemispherically-shaped or elongated. A guide wire lumen extends through the shaft, from the proximal end to the distal end, for receiving a guide wire. At least one dye-injection lumen extends through the elongated shaft from the proximal end and joins the guide wire lumen at a point near the distal end of the shaft to provide fluid communication between the injection lumen and the guide wire lumen. The shaft is slidably inserted through the hollow interior of a guide catheter so that the hemispherically-shaped or elongated distal end of the shaft extends beyond the distal end of the guide catheter. Thus, the hemispherically-shaped or elongated distal end cooperates with the guide catheter body to provide a smooth rounded catheter tip which, when advanced along the patient's vasculature, reduces the risk of causing trauma to the blood vessel, freeing plaque from the vessel wall, or creating embolisms in the bloodstream.
