  • Patent number: 11553909
    Abstract: Medical devices for applying a cinch to a suture and methods for making and using such devices are disclosed. An example medical device may include an elongated shaft including a proximal region and a distal region. The distal region may define a lumen having a lumen dimeter, and a distally facing end surface. The medical device may also include an outer cinch member defining a bore and having an outer surface defining a shoulder. An elongated inner shaft may extend through and be longitudinally movable within the lumen and the bore and including a distal end section. An inner cinch member may be engaged with the distal end section of the elongated inner shaft.

  • Patent number: 9642734
    Abstract: An implant includes a collapsible anchor to be deployed within a lumen and a protrusion coupled to the anchor. The protrusion, in a constrained state, extends a distance from an exterior surface of the anchor and, in an unconstrained state, extends further from the exterior surface of the anchor. Also included is a biodegradable constraint, such as a biodegradable tube or suture, configured to maintain the protrusion in the constrained state until the constraint releases. The implant may include additional biodegradable constraints, each constraint configured to maintain the protrusion in a different constrained state and to degrade over a different predetermined period after the implant has been deployed within the lumen. The protrusion may include a bi-directional barb or an open loop. The protrusion may be configured to penetrate a wall of the lumen and to allow tissue to grow about the protrusion.

  • Patent number: 9265596
    Abstract: An implant (100) includes a protrusion (110) with an open or rounded loop (112) (or open head) connected to a collapsible anchor. The protrusion may include a straight length of wire (114) or a helical length wire, with one or more wire loops (112) at the end of the length forming the loop. Upon deployment within the gastrointestinal tract, the protrusion expands from a collapsed state, alongside the anchor, to a relaxed state, in which the protrusion extends outward from the anchor. As the protrusion expands to its relaxed state, it pushes the loop into the wall of the duodenum, causing the loop to penetrate the duodenal wall. A pocket of scar tissue forms about the head and possibly through an opening in the head, securing the anchor within the duodenum. The implant may also include a thin-walled sleeve that is coupled to the anchor and extended from the anchor into the intestine.

  • Patent number: 8668728
    Abstract: The invention relates to a system for dilatation of a body passage and delivery of a stent into the body passage of a patient, and related methods of using such a system. The dilatation and stent delivery system may comprise a dilatation catheter having an expandable member on a distal end, and a stent delivery catheter configured to retain a stent and deliver the stent to a body passage. The stent delivery catheter defines a lumen sized to receive the dilatation catheter and permit movement of the dilatation catheter relative to the stent delivery catheter.

  • Publication number: 20090171434
    Abstract: Prosthesis loading and deploying systems include a capturing device with a proximal stent-engaging member and an elongate pulling member extending distally from the stent-engaging member. With a prosthesis or stent in a relaxed or enlarged-radius state, the pulling member is guided distally through a delivery catheter, pulling the stent-engaging member and prosthesis into the catheter lumen to progressively radially compress the prosthesis to a reduced-radius state. Simultaneously the distal end region of an elongate control device is maintained within a proximal region of the prosthesis, so that the prosthesis is compressed about the control device distal end region as these components enter the catheter. When the prosthesis is compressed about the control device, it tends to follow axial movement of the control device, thus to afford reliable positional control of the prosthesis inside the catheter by manipulating the control device.

  • Publication number: 20070112437
    Abstract: An anti-reflux stent includes an extended inner sleeve, a stent surrounding at least a portion of the inner sleeve and a coating that bonds the stent to the inner sleeve whereby the extended inner sleeve can have a cross-sectional thickness that varies along the length of the inner sleeve. The inner sleeve is made of a material having a thickness and/or flexibility such that the distal end not surrounded by the stent collapses under gastric pressure to prevent the contents of the stomach from flowing into an esophagus. Food and liquid can pass through an inner lumen of the inner sleeve to enter a stomach when desired.

  • Publication number: 20050113904
    Abstract: A composite stent structure includes separate and distinct stent elements or members: an outer stent element and an inner stent element removably attached to the outer stent element. The outer element may be, for example, a bioabsorbable stent typically constructed of a relatively non-resilient material such that the outer bioabsorbable stent element may not be self-expanding and subject to migration within the lumen over time. In contrast, the inner element may be, for example, a removable SEMS used to urge and maintain the outer element in position in the body lumen. The temporary inner SEMS may retain the composite structure (including the underlying inner element) in position until such time as the outer element is appropriately incorporated into the surrounding tissue or some other criteria occurs such that the removal of the SEMS is indicated. The SEMS may then be detached from the outer element and removed from the body lumen.

  • Publication number: 20050096721
    Abstract: An apparatus for use by an operator in a cavity of a mammalian body with a scope having a distal face providing a field of view. The apparatus includes a flexible elongate member having a distal extremity adapted for extending into the cavity and a proximal extremity accessible from outside of the mammalian body when the distal extremity is disposed in the cavity. An expandable prosthesis is releaseably secured to the distal extremity of the flexible elongate member. A visual marker capable of being seen by the operator in the field of view is secured to one of the distal extremity of the flexible elongate member and the prosthesis for facilitating placement of the prosthesis in the mammalian body.
