| 20090182407 | LUER OR CLAMP-TYPE SUTURE RELEASE APPARATUS AND METHOD FOR LOADING AND DELIVERING A STENT - An assembly for delivering a self-expanding stent within a body lumen is includes a self-expanding stent, a delivery catheter for delivering the stent, a transfer member removeably engagable with a distal end of the delivery catheter, and an elongate filament for manipulating the stent through the passage of the transfer member. The delivery catheter includes an elongate flexible shaft having a stent holder at its distal end for restraining axial movement of the stent when the stent is disposed within a hollow cylindrical passage of an elongate tube moveably disposed over a portion of the shaft, and a handle secured to the proximal end of the flexible shaft. The elongate filament is releasably secured to the stent, and the ends of the filament are accessible at the handle to permit movement of the stent within the device by manipulation of the filament. | 07-16-2009 |
| 20100161034 | STENTS WITH ATTACHED LOOPED ENDS - An open frame prosthesis is formed with looped end terminations at its proximal and distal ends. At one end of the prosthesis, the filaments or strands are welded together in pairs to form strand couplings. A plurality of loop segments are connected to the strand couplings, one loop segment for each pair of adjacent strand couplings. In one version of the prosthesis, strands at the opposite end are bent to form looped ends. In another version, loop segments are connected to pairs of strand couplings at both ends of the prosthesis. The loop segments can be connected to the couplings by welding, fusion bonds, or tubes, which are either crimped or heat shrunk. | 06-24-2010 |
| 20100240954 | MEDICAL DEVICE POSITIONING SYSTEM - Embodiments of the invention include a medical device for accessing a patient's body portion and used for diagnosis and treatment of medical conditions. Embodiments of the invention may include a particular endoscopic positioning mechanism for placing an endoscope and an additional treatment device within desired body portions in order to assist in diagnosis and treatment of anatomical diseases and disorders. In particular, a medical device according to an embodiment of the invention may include an outer flexible tube and a positioning mechanism configured for rotating one portion of the flexible tube relative to another portion of the flexible tube. | 09-23-2010 |
| 20110028984 | RAPID EXCHANGE ENTERAL STENT DELIVERY SYSTEM - Devices for palliating gastrointestinal strictures using rapid exchange type enteral stent placement catheters. The catheter may include an inner member and an outer member, with the two members being slidable with respect to one another. In various device embodiments, a ramp for directing a guidewire out from within the catheter is provided using portions of the outer member or a shaped mandrel. The inner member may take a number of forms, including a tubular distal portion, a skived or integrally attached elongate midsection, and a proximal portion. A mandrel can be used in a portion proximal of the guidewire ramp, with the mandrel taking one of several disclosed forms. | 02-03-2011 |
| 20110079315 | ATRAUMATIC STENT WITH REDUCED DEPLOYMENT FORCE, METHOD FOR MAKING THE SAME AND METHOD AND APPARATUS FOR DEPLOYING AND POSITIONING THE STENT - An implantable stent includes a plurality of elongate wires braided to form a hollow tubular structure having a tubular wall to define an interior surface and an exterior surface and having opposed open first and second ends, wherein the opposed open first and second ends are atraumatic ends. The atraumatic ends of the stent are desirably free of any loose wire ends. The wires include composite wires to enhance visibility of the wires to provide improved external imaging of the wires in the body. The elongate composite wires of the stent may be metallic wires having an outer metallic portion including a first metal, such as nitinol, and an inner metallic core portion including a second metal, which is a radiopaque material, such as gold, barium sulfate, ferritic particles, platinum, platinum-tungsten, palladium, platinum-iridium, rhodium, tantalum or combinations thereof. | 04-07-2011 |
| 20110295359 | Stent With Reduced Weld Profiles and a Closed-End Wire Configuration - A method for making an implantable stent includes the steps of (i) providing a plurality of elongate stent wires; (ii) forming said wires into a hollow tubular structure having opposed first and second open ends; (iii) terminating said wires at the second end; (iv) aligning the wires at the second end into a plurality of mated adjacent wires to define a plurality of abutting regions; (v) welding the mated adjacent wires to one and the other at the abutting regions to define a plurality of welds; and optionally (vi) chemically or electro-chemically removing a portion of the welds. The method may further include the steps of (a) extending at least one of the mated stent wires to provide an extended stent wire; (b) looping the extended stent wire so the extended end abuts a proximal pair of stent wires; and (c) welding the extended and looped wire to the proximal pair of wires. The step of looping may include the forming of the wire into a equilaterally arched loop having an apex, but not having other sharp bends. | 12-01-2011 |
| 20110313404 | STENT DELIVERY SYSTEM HAVING RETENTION STRUCTURE - A stent delivery system including an elongate shaft of a medical device, a stent selectively coupled to a distal portion of the elongate shaft, and a coupling mechanism for selectively coupling the stent to the elongate shaft by inserting a tab on one of the stent or the elongate shaft into an opening in the other of the stent or the elongate shaft. The tab may be deflected from a first position to a second position to disengage the tab from the opening. | 12-22-2011 |
| 20110319904 | DELIVERY SYSTEM HAVING STENT RETENTION STRUCTURE - A drainage stent delivery system including an elongate shaft of a medial device, a drainage catheter or stent, and an interference fit member for selectively coupling the drainage stent to the elongate shaft. The drainage stent is selectively coupled to a distal portion of the elongate shaft by an interference fit between the interference fit member and the drainage stent such that axial movement of the elongate shaft relative to the drainage stent moves the interference fit member from a first position in which the interference fit member is engaged with the drainage stent and forms an interference fit with the drainage stent to a second position in which the interference fit member is disengaged from the drainage stent. | 12-29-2011 |
