20080234799 | CUSTOM-LENGTH STENT DELIVERY SYSTEM WITH INDEPENDENTLY OPERABLE EXPANSION ELEMENTS - A stent delivery system for delivering a plurality of stent segments to at least one treatment site includes a catheter shaft having a proximal end and a distal end, a plurality of expandable members arranged axially along the catheter shaft near the distal end, a plurality of stent segments, and a selecting mechanism adapted for selecting one or more expandable members for expansion. Each expandable member is expandable independently of at least one other expandable member, and each expandable member has at least one stent segment positioned on it. One or more of the expandable members may be selectively expanded to deploy the one or more stent segments positioned thereon at the treatment site. | 09-25-2008 |
20090076584 | APPARATUS AND METHODS FOR DEPLOYMENT OF MULTIPLE CUSTOM-LENGTH PROSTHESES - A catheter for delivering a prosthesis to a target treatment site comprises an inner shaft and an expansion member coupled to the inner shaft. A plurality of radially expandable prosthetic segments are positionable over the expansion member and they are releasably interlocked with one another while unexpanded. Adjacent pairs of prosthetic segments may decouple from one another upon radial expansion of the distal prosthetic segment in the adjacent pair while the proximal segment in the pair remains at least partially unexpanded. The catheter also includes an outer sheath that is axially movable and positionable at least partially over the prosthetic segments to constrain expansion of a selectable number of segments. A segment mover is coupled to at least one of the prosthetic segments and is axially movable so as to retract one or more of the segments when the one or more prosthetic segments are unexpanded. | 03-19-2009 |
20110125248 | CUSTOM LENGTH STENT APPARATUS - Apparatus and methods for delivering prosthetic segments to a body lumen, utilize a device having an elongated flexible member including proximal and distal ends, a plurality of prosthetic segments releasably arranged axially along the elongated flexible member near the distal end and an outer sheath slidably disposed over at least a portion of the prosthetic segments. The apparatus further includes a separator disposed on the outer sheath and adapted to engage the prosthetic segments. The separator is also adapted to be retracted proximally over the prosthetic segments and advanced distally to separate a proximal group of the prosthetic segments from a distal group of the prosthetic segments which are to be deployed in the body lumen. | 05-26-2011 |
20110152996 | APPARATUS AND METHODS FOR DELIVERY OF MULTIPLE DISTRIBUTED STENTS - Delivery catheters and systems are adapted for delivering multiple discreet prostheses in body lumens. An exemplary delivery catheter comprises a sheath, a pusher for moving the prostheses relative to the sheath, and a valve member for selectively retaining the prostheses in the sheath. For balloon expandable stents, an elongated shaft and an expandable member are slidably disposed in the sheath, and the prostheses are positionable on the expandable member for deployment in the body lumen. The valve member allows a selected number of prostheses to be deployed from the sheath while retaining other prostheses within the sheath. | 06-23-2011 |
20130261382 | Devices and Methods for the Treatment of Obesity - A device includes a reinforcing member with a cross-section that defines a channel. The channel is configured to reinforce a wound. The device further includes a constraining body attachable to the reinforcing member and the constraining body is configured to constrain a patient's stomach. Methods for implanting the device and treating a patient are provided. | 10-03-2013 |
