20080208314 | Prosthesis having a sleeve valve - Disclosed is a pressure sensitive prosthesis that includes a tubular member having a passageway extending therethrough and a sleeve attached about one end of the tubular member. The sleeve functions as a one-way valve to permit fluid flowing through the sleeve lumen in a first, distal direction and under a first pressure, while collapsing in response to fluid flowing in a second direction when the pressure thereof exceeds that of the first direction or pressure. One aspect of the invention includes a first opening and a second opening configured for allowing fluid flow from the passage to the lumen in the first direction. | 08-28-2008 |
20080242934 | ENDOSCOPIC SUCTION DEVICE FOR MUCOSECTOMY - An endoscopic suction device of an endoscope for mucosectomy is disclosed. The device comprises a connecting base having an open end attachable to the distal end of the endoscope. The device further comprises a distal tip extending from the connecting base and having a closed distal end. The distal tip comprises a suction chamber formed therein and in fluid communication with the open end. The suction chamber has a suction opening formed laterally therethrough for suctioning lesions during mucosectomy. | 10-02-2008 |
20080262301 | STEERABLE OVERTUBE - A steerable overtube is provided having an elongate shaft comprising an oversized accessory channel that is configured for the introduction and advancement of elongate medical devices having relatively large cross-sections. The distal end of the overtube shaft is bendable or deflectable in at least one direction, and is preferably includes a shape locking mechanism for temporarily maintaining the shape of the distal end of the overtube shaft. An oversized accessory channel is provided. The overtube may also include a fixation mechanism for securing the proximal end and/or distal end of the overtube against movement relative to the patient. A fiber optic elongate medical device is provided for use with the steerable overtube of the present invention. | 10-23-2008 |
20090105539 | ENDOSCOPE CAP WITH APERTURE - An end cap for an endoscope. The end cap is configured to allow the endoscope to be introduced into a patient body by a short-wire type of operation. | 04-23-2009 |
20090182198 | MULTIPLE BAND DISPENSER ENDOSCOPE SHEATH - A protective sheath comprising a cap member configured for attachment to the distal end of an endoscope and a flexible, elongate outer sleeve attached to the cap member and adapted to unfold over the endoscope in a proximal direction along a substantial portion of the endoscope to protect the endoscope from bodily fluids. | 07-16-2009 |
20100161024 | OVER THE ENDOSCOPE INTRODUCER FOR STENTS - Over-the-scope stent introducers for detachably engaging at least a portion of the outside of an endoscope insert and for delivering a stent are provided. Embodiments include an inner member having a distal first end portion and a proximal second end portion and openings defining a channel. The inner member includes an outer surface, inner endoscope engaging surface, and stent abutting restraint disposed at the first end portion. Embodiments also include an outer member having a distal section and proximal section having openings defining a passageway sized to slideably receive at least a portion of the inner member, and a stent carrying inner chamber disposed at the distal section passageway and being configured to releasably contain a stent. In alternative embodiments, the inner and outer members are elongated to dispose substantially concentrically over a majority of an endoscope insert. | 06-24-2010 |
20100168665 | SEGMENTED BALLOON FOR CATHETER TIP DEFLECTION - A balloon catheter is provided that may be used to maneuver around tortuous body lumens. The balloon catheter comprises one or more balloons disposed about a tip of the shaft. Each balloon includes a dedicated lumen to allow inflation of each balloon independent of the others. Inflation of a balloon causes the shaft tip to deflect in a direction that is oriented opposite of the inflated balloon. The bent orientation of the shaft tip allows the catheter and a guide wire to be maneuvered through tortuous body lumens. | 07-01-2010 |
20110087234 | SYSTEM AND METHOD FOR INTRODUCING MULTIPLE MEDICAL DEVICES - A method and apparatus for introducing a first elongate medical device and short wire guide that are coupled together into a work site and remotely disconnecting them within the work site such that a secondary device comprising a catheter member can be introduced over the wire guide to the work site, and/or a second wire guide can be introduced to the work site via a passageway of the primary access device. A separating member may be provided to remotely separate the wire guide from the elongate medical device. A system of indicia, such as radiopaque or viewable markers, permits the operator to monitor the relative alignment of the devices within the work site to determine when uncoupling has occurred. In one example of the method, a wire guide and primary access device (e.g., a sphincterotome) is coupled to the wire guide and introduced via a duodenoscope into the biliary system. After performing a first medical operation, the devices are uncoupled with the wire guide being left within the biliary system such that a secondary access device, such as a balloon, biopsy device, stent delivery catheter, dilator, etc., can be introduced to perform a second medical operation without a traditional over-the-wire exchange being required. In another example of the method, a prosthesis, such as a valve or stent, is placed within the work site coupled to a wire guide which is remotely disconnected within the work site and a secondary device, such as a dilation balloon or second prosthesis, is introduced into the work site after the first delivery system is removed. | 04-14-2011 |
20120083804 | MARKER CLIP DEVICE - A marker clip device and system for marking tissue within a body cavity comprising a plurality of deployable marker clips having unique markings or other indicia to thereby allow each clip to be individually identified subsequent to clip deployment. A clip delivery device configured to deploy the plurality of marker clips at various locations within a body cavity is also provided. | 04-05-2012 |
20130197554 | APPARATUS AND METHODS FOR ENDOSCOPIC RESECTION OF TISSUE - The present invention provides apparatus and methods for performing endoscopic mucosal resection and endoscopic submucosal dissection of tissue. In a first embodiment, a catheter having proximal and distal ends and a balloon disposed near the distal end of the catheter is provided. A portion of the distal end of the catheter is configured to be inserted beneath a section of mucosal tissue having a lesion, and the balloon is configured to be inflated to lift the mucosal tissue in an upward direction, thereby facilitating removal of the tissue comprising the lesion. Optionally, a surgeon may advance a needle knife through the catheter to further incise submucosal tissue while the balloon is in the inflated state. If to desired, a flushing fluid may be provided to a target site during the procedure. | 08-01-2013 |
