Patent number: 9814571Abstract: Described are devices and methods for medically sealing a perivalvular leak associated with implanted valves. For example, a bioresorbable tissue infiltratable sheet is provided for insertion through a perivalvular leak. A filament extending through the sheet is also provided which when pulled causes the sheet to gather around the filament on either side of the perivalvular leak. The gathered position of the sheet may be secured by a series of stops and/or use of a capping member.Type: GrantFiled: January 7, 2015Date of Patent: November 14, 2017Assignees: Cook Medical Technologies LLC, Cook Biotech IncorporatedInventors: Chad E Johnson, Charles L.

Patent number: 9271820Abstract: A filter device assembly and a method of using such a device to capture and remove embolic material from a body lumen or blood vessel are provided. The filter device assembly generally includes a structure having a collapsed state and an expanded state with first, second, and optionally N additional filter members circumferentially attached thereto. Each filter member forms an annulus chamber with the first filter member having porosity P1; the second filter member circumferentially having porosity P2; and the N additional filter members each having porosity [P3 . . . P(2+N)]. The magnitude of the porosity for the first, second, and N additional filter members follows the relationship P1>[P3>. . . >P(2+N)]>P2. The first, second, and N additional filter portions are configured in the expanded state to allow blood to flow there through and to capture emboli in the annulus chambers.Type: GrantFiled: November 19, 2013Date of Patent: March 1, 2016Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Charles L.

Patent number: 9101449Abstract: There are disclosed embodiments of a system for retrieving a filter device from within a patient. A tube or sheath and one or more cables or other elongated members, which include a protrusion such as a bead at or adjacent a distal end, are movable with respect to each other. When the tube or sheath is adjacent a filter device, the cable or elongated member is extended so that the protrusion is between or through wires of the filter, and the protrusion is engaged to or between two or more of the wires. The filter is placed within the tube or sheath, as by retracting the cable or elongated member to pull the filter, by moving the tube or sheath over the cable or elongated member while it engages the filter under tension, or both.Type: GrantFiled: September 12, 2012Date of Patent: August 11, 2015Assignee: Cook Medical Technologies LLCInventors: Louis B.

Patent number: 8821565Abstract: An assembly for open surgical repair of a damaged wall portion of a body vessel includes a stent/graft device comprising an elongated stent body and a graft material covering the stent body. The device is expandable from a compressed condition having a diameter less than a diameter of the vessel to an expanded condition at least as great as the diameter of the vessel. A sheath enclosing the device when in the compressed condition includes a sheath body and a pull string for selectively splitting the sheath body to allow expansion of the device. The device and enclosing sheath are sized for insertion through the damaged wall portion into the vessel, wherein the pull string is extendable through the damaged wall portion for splitting the sheath body.Type: GrantFiled: May 22, 2012Date of Patent: September 2, 2014Assignee: Cook Medical Technologies LLCInventors: Demetrios Demetriades, Bruce Gingles, James B.

Publication number: 20140155987Abstract: A low profile support frame for use as or in an expandable intraluminal medical device includes first and second wire members that define arcuate paths having opposing curves. Connectors join the wire members. A stabilizing member has a proximal end contained within one of the connectors. The support frame has radially compressed and radially expanded configurations. When the support frame is in the radially expanded configuration, substantially no portion of the support frame is disposed on a first transverse axis of the frame opposite one end of the frame and substantially no portion of the frame is disposed on a second transverse axis of the frame opposite the other end of the frame. The support frame can be used as an intraluminal medical device by itself or as a component in a medical device that includes other components, such as a stent, prosthetic valve, occluder, or filter.Type: ApplicationFiled: February 5, 2014Publication date: June 5, 2014Applicant: COOK MEDICAL TECHNOLOGIES LLCInventors: Ram H.
