Patent number: 8348988Abstract: An endoluminal prosthetic device for placement in a body lumen is formed by stitching stents to a graft. A first or anchoring stent is used for securing a graft made of biocompatible material that forms at least one lumen. There is also a second stent. The first and second stents each include a plurality of struts and apices between the struts. At least two of the apices in each of the first and second stents are secured to the graft by stitches. A running suture links at least one stitch of the first stent and one stitch of the second stent. The running suture linking the first stent and the second stent adds strength to the stitches and better secures the first stent to the device. The endoluminal prosthetic device may be used in an aortic vessel to treat stenoses or aneurysms.Type: GrantFiled: January 18, 2005Date of Patent: January 8, 2013Assignee: Cook Medical Technologies, LLCInventors: Ashvin Lad, Michael P.

Patent number: 7753918Abstract: A medical grasping device (1) has an elongate control member (9) with a grasping member (17) proximal to its distal tip. An outer sheath (3) with a passageway therethrough surrounds the elongate control member and is relatively movable with respect to the control member. A control assembly (2) disposed at a proximal end of said outer sheath has a fixed handle (5) and a sliding handle (7) and the proximal end of the elongate control member is fixed to the sliding handle to move the control member.

Patent number: 7081132Abstract: A barbed medical prosthesis is disclosed in which the barb includes a basal portion comprising a point of union with the substrate of origin (such as a strut), an anchoring portion adapted to embed into tissue, and a stress-dispersing portion located between the basal and anchoring portions. In one embodiment the stress-dispersing portion comprises a helical coil having a free winding that is unattached to the strut from which the barb extends. In another embodiment, the stress-dispersing portion comprises a series of bends or curves formed in the barb proximate to the point of union with the strut. The barb can be mechanically attached and/or soldered to the prosthesis, or integrally formed therefrom. A second barb portion and stress-dispersing portion, may also extend from the basal portion.Type: GrantFiled: May 8, 2003Date of Patent: July 25, 2006Assignee: Cook IncorporatedInventors: William A.

Patent number: 6565597Abstract: An expandable stent prosthesis is disclosed in which the apices of the bends located at at least one end of the stent are individually twisted at an angle to the circumference of the stent to form a fan blade-like arrangement when viewed from that end. The fan blade-like arrangement allows the stent to expand from the compressed condition during deployment such that likelihood of a strut or bend of the stent become entangled with a barb or adjacent strut or bend, is reduced. In one embodiment of the invention, the fan blade-like arrangement results from plastically deforming the individual apices, while in another embodiment, the apices are twisted into the fan blade-like arrangement during the loading process, such as by use of a suture thread to pull the apices into alignment.Type: GrantFiled: July 17, 2000Date of Patent: May 20, 2003Assignees: MED Institute, Inc., Cook IncorporatedInventors: Neal E.

Patent number: 6524336Abstract: Disclosed is a medical device graft arrangement comprising a main graft and at least one peripheral graft wherein the grafts are expandable. Upon insertion of the peripheral graft(s) into the main graft, the peripheral grafts expand and seal the junction of the graft arrangement to provide fluid communication between the lumens of the main and peripheral grafts. The graft arrangement optionally has a cover folded in such a manner to provide further sealing.Type: GrantFiled: April 6, 1999Date of Patent: February 25, 2003Assignees: Cook Incorporated, William Cook, Europe A/SInventors: Konstantinos O.

Patent number: 5720776Abstract: An improved prosthesis assembly for placement at an aneurysm in the bifurcated lumen of the aorta and the common iliac arteries extending therefrom. The prosthesis assembly includes a single lumen graft or a bifurcated lumen graft having a main body and ipsilateral and contralateral limbs extending therefrom. The main body and ipsilateral and contralateral limbs each have a spring assembly about their orifices for conforming that portion of the graft to the wall of the vessel lumen. The main body spring assembly has an improved barb with first and second attachment arms for securely anchoring the spring assembly to the vessel wall. The improved barb includes two forms of mechanical attachment such as, for example, a helical coil body positioned around a spring assembly arm and, secondly, a bonding material such as, for example, solder for fixedly attaching the coil and spring assembly arm.Type: GrantFiled: June 7, 1995Date of Patent: February 24, 1998Assignees: Cook Incorporated, MED Institute, Inc.Inventors: Timothy A.

Patent number: 5106368Abstract: A dual lumen catheter is disclosed for providing extracorporeal treatment such as hemodialysis, which is percutaneously inserted for either short-term or long-term vascular access. The catheter includes a main body having proximal and distal segments connected to a pair of clamping limbs via a manifold. The distal segment includes two tubular members laterally attached to each other, one of which is thinner than the other and collapsible for inserting the catheter through a much smaller diameter peel-away sheath. Contrary to existing practices, the lengths of the arterial and venous tubular members are reversed such as to provide a longer negative pressure intake lumen. A hydrophilic slip coating covers the distal segment to further ease the insertion of the distal segment into the peel-away sheath. The cross-sectional area of the proximal segment is generally elliptical shaped for providing a leak proof fit through the vascular access site.Type: GrantFiled: April 20, 1990Date of Patent: April 21, 1992Assignee: Cook IncorporatedInventors: Peter R.
