Patent number: 8911488Abstract: A stent graft delivery device (30) has a pull wire arrangement with a pull wire (46) fastened to the distal end of a nose cone dilator (45) and extending to a wire pull mechanism (60) for the pull wire associated with a handle (52) of the stent graft delivery device. The pull wire can be pulled by the wire pull mechanism to induce a curve in a guide wire catheter (44) distally of the nose cone dilator such that the proximal end of the delivery device more closely fits the shape of a portion of the vasculature of a patient into which the device is deployed.Type: GrantFiled: August 24, 2009Date of Patent: December 16, 2014Assignees: The Cleveland Clinic Foundation, Cook Medical Technologies LLCInventors: David E.

Patent number: 8808349Abstract: A stent graft introducer (1) which includes a handle arrangement which by telescopic movement of a slide or slide portions (104, 106) into a handle portion (100) causes controlled sequential deployment of a stent graft (14). Stops (218,217, 218, 219) ensure actions are carried out in a selected order. A sheath (116) of the introducer is fixed to a slide portion such that with retraction of the slide portion the sheath is withdrawn from a stent graft retained on the introducer and at a selected position trigger wires retaining the stent graft onto the introducer are also released. Interconnections between the slides and the handle are provided to prevent relative rotation and re-extension after full retraction.Type: GrantFiled: March 8, 2012Date of Patent: August 19, 2014Assignee: Cook Medical Technologies LLCInventors: Timothy A.

Patent number: 8672993Abstract: A stent graft for endovascular introduction into the pararenal region of the descending aorta. The stent graft has an elongate tubular body (10) with a proximal portion (12), a distal portion (16) of a diameter less than the proximal portion and a tapered central portion (14). A notional transverse clock face on the tubular body has 12 o'clock at a notional anterior longitudinal datum line. The stent graft has a scalloped cut out (26) centered at about 12:30 o'clock and a fenestration (28) at about 12:00 o'clock in the proximal portion and first and second fenestration assemblies which can be low profile side arms at about 2:15 o'clock and about 10:00 o'clock in the tapered central portion. The tapered central portion can have an arcuate side wall (30) so that the tapered portion has an outer face which is concave.Type: GrantFiled: March 26, 2010Date of Patent: March 18, 2014Assignee: Cook Medical Technologies LLCInventors: Timothy A.

Patent number: 8574284Abstract: A stent graft for use in a medical procedure to treat a dissection of a patient's ascending thoracic aorta. The stent graft includes bare alignment stents at least at a proximal end, and often with a stent at both ends, each stent having opposing sets of curved apices, where the curved section of one broader set of apices has a radius of curvature that is greater than the curved section of the other narrower set of apices. The proximal stent is flared in a manner such that its broad apices occupy a larger circumference around the stent than do its narrower apices, where this flared feature provides for anchoring engagement near the aortic root in a manner not interfering with the coronary arteries or the aortic valve.Type: GrantFiled: May 26, 2009Date of Patent: November 5, 2013Assignee: Cook Medical Technologies LLCInventors: Blayne A.

Publication number: 20120116498Abstract: The present embodiments provide a valve for implantation in a patient, for example, an aortic valve. The valve comprises a proximal region comprising a cylindrical shape, and a distal region having a generally rectangular shape comprising opposing flat surfaces that are separated by narrower flat sides. A tapered region is disposed between the proximal and distal regions, where the tapered region comprises two opposing flat surfaces that transition into the opposing flat surfaces of the distal region. The opposing flat surfaces of the tapered region are angled relative to the proximal and distal regions. The opposing flat surfaces at the distal end of the valve allow fluid flow therethrough during antegrade flow and are generally adjacent to one another to inhibit blood flow through the valve during retrograde flow. Optionally, at least one reinforcement member may be coupled to the valve to prevent prolapse of the valve during retrograde flow.Type: ApplicationFiled: November 1, 2011Publication date: May 10, 2012Inventors: Timothy A.

Publication number: 20110172762Abstract: A stent graft (10) has a tubular body (12) of a biocompatible material and at least one fenestration (18, 20). The or each fenestration has a tubular side branch stitched into it with a portion of the tubular side branch extending within the tubular body and a portion of the tubular side branch extending exteriorly of the tubular body. The stitching by which the tubular side branch is mounted into the fenestration extends circumferentially and diagonally from one end of the tubular side branch to the other such that the tubular side branch extends from the tubular body at an angle thereto. The tubular side branch has a resilient ring around at least one and preferably both ends thereof and a self expanding stent in between them. The tubular side branch can have a circumferential linear portion (46) at an inner end to engage against the inner wall (58) of the tubular body.Type: ApplicationFiled: March 22, 2011Publication date: July 14, 2011Applicants: William A.
