Patent number: 10034751Abstract: A delivery system for an implantable medical device having at least one retention member at an end thereof includes a shaft extending in a longitudinal direction. An elongated sheath surrounds the shaft. The sheath is slidable relative to the shaft in the longitudinal direction. A space is defined inside of the sheath and is adapted to receive the medical device in an assembled or collapsed condition. A retainer is positioned at a first end of the space. At least one recess is provided in the retainer and is adapted to receive the retention member of the medical device in the assembled condition. A selectively activable member is disposed in the compartment between the longitudinal shaft and the medical device. When in an activated state, the member expands radially relative to the shaft, thereby urging the retention member to disengage from the recess.Type: GrantFiled: May 12, 2016Date of Patent: July 31, 2018Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Valerie J. Glazier, Huisun Wang, Alex Grafov

Patent number: 9119717Abstract: A delivery device for an implantable medical device having at least one retention member at an end thereof includes a shaft extending in a longitudinal direction, an elongated sheath surrounding a longitudinal portion of the shaft, a compartment defined inside of the sheath and adapted to receive the medical device in an assembled condition, a retainer positioned at one end of the compartment, and at least one acceptance in the retainer adapted to receive the retention member of the medical device in the assembled condition. The sheath is slidable relative to the shaft in the longitudinal direction to uncover and deploy the medical device. The retainer may be rotatable relative to the shaft to reduce torsional forces in the medical device during delivery and deployment. The retainer may have at least one recess facing the compartment for receiving a strut at an end of a stent of the medical device.Type: GrantFiled: July 12, 2011Date of Patent: September 1, 2015Assignee: St. Jude Medical, Inc.Inventors: Huisun Wang, Valerie J.

Publication number: 20120065571Abstract: A gastrointestinal device for implanting within a patient's gastrointestinal tract includes first and second expandable anchoring rings configured to be disposed on either side of a patient's pylorus. The first expandable anchoring ring has a collapsed configuration and an expanded configuration, wherein in the expanded configuration the first expandable anchoring ring has a diameter larger than a maximum opening diameter of the pylorus. The second expandable anchoring ring also has a collapsed configuration and an expanded configuration, wherein in the expanded configuration the second expandable anchoring ring has a diameter larger than a maximum opening diameter of the pylorus. An intestinal bypass sleeve couples the first expandable anchoring ring and the second expandable anchoring ring, so as to allow a distance between the anchoring rings to exceed a width of the pylorus.Type: ApplicationFiled: November 17, 2011Publication date: March 15, 2012Applicant: MetaModix, Inc.Inventors: Paul J.

Publication number: 20080312664Abstract: A medical device is disclosed for tissue, body lumen and/or cavity closure inside a body of a patient. In one particular application, the medical device can be used for minimally invasive access and closure of a left atrial appendage of the heart. The medical device generally includes a tool used for grasping the appendage, a closure member, and at least one tool to deploy, control, and position the closure member for closing the appendage. The device can also include an expander tool for expanding the working area around the left atrial appendage to improve visibility during the procedure. In other embodiments, the medical device may include other tools, for example an imaging tool for viewing the target area and/or other tools that are considered useful in a left atrial appendage closure procedure.Type: ApplicationFiled: May 12, 2008Publication date: December 18, 2008Applicant: EPITEK, INC.Inventors: Earl Bardsley, Jianlu Ma, Jean Paul Rasschaert, Thomas J.
