Patent number: 9642734Abstract: 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.Type: GrantFiled: August 14, 2014Date of Patent: May 9, 2017Assignee: GI Dynamics, Inc.Inventors: David A. Melanson, Christopher Nutting, Barry Maxwell, Peter Shank, John Panek

Patent number: 9265596Abstract: 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.Type: GrantFiled: September 10, 2010Date of Patent: February 23, 2016Assignee: GI Dynamics, Inc.Inventors: Peter Shank, David A.

Patent number: 8668728Abstract: 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.

Publication number: 20090171434Abstract: 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.Type: ApplicationFiled: December 17, 2008Publication date: July 2, 2009Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Emily Rusk, Peter Shank, Michael Abi-Kheirs

Publication number: 20070112437Abstract: 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.Type: ApplicationFiled: January 3, 2007Publication date: May 17, 2007Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventor: Peter Shank

Publication number: 20070055352Abstract: A medical device for: delivering a therapeutic agent to a body lumen is described. The device may generally be a stent with an inner sidewall surface and an outer sidewall surface, with a plurality of struts having a plurality of openings therein. An inner and outer layer may be applied to the stent, forming pockets within at least a portion of the openings. The pockets may be filled with at least one therapeutic agent. The pockets may take a variety of shapes and sizes, and may be designed for release or rupture in variety of ways.Type: ApplicationFiled: September 7, 2005Publication date: March 8, 2007Inventors: Wendy Naimark, Peter Shank, Maria Palasis, Toby Freyman, Anastasia Panos, Samuel Epstein, Alexandra Rousseau

Publication number: 20050113904Abstract: 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.Type: ApplicationFiled: November 25, 2003Publication date: May 26, 2005Inventors: Peter Shank, F. Headley

Publication number: 20050096721Abstract: 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.Type: ApplicationFiled: October 29, 2003Publication date: May 5, 2005Inventors: Stephen Mangin, Peter Shank
