Patent number: 10772649Abstract: A clot retrieval device, for example to be used in a thrombectomy, is provided including a catheter, an elongated member, and a knitted basket with a proximal end coupled to the catheter and a distal end coupled to the elongated member. The elongated member is movable between an expanded position and a compressed position relative to the catheter and is configured so that the knitted basket expands radially and compresses as the elongated member is moved to the compressed position. The knitted basket is comprised of a plurality of wires coupled together by a plurality of windings. Each winding comprises one of the plurality of the wires twisted about another of the plurality of wires.Type: GrantFiled: September 27, 2017Date of Patent: September 15, 2020Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Palle Munk Hansen, Tue Thuren Bödewadt

Patent number: 10463376Abstract: An implantable medical device includes first and second material capture elements which are disposed in opposing orientations and have their narrow ends facing one another. The first and second material capture elements are connected by a flexible connector, which enables the implantable medical device to curve within a curved vessel of a patient. The flexible connector is either closed or has a lumen passing therethrough and includes a closure element for closing the lumen after deployment of the device within a patient. The structure enables the device to be positioned reliably within a curved vessel and benefits from the advantage of a double-ended device.Type: GrantFiled: January 9, 2015Date of Patent: November 5, 2019Assignee: Cook Medical Technologies LLCInventors: Tue Thuren Bödewadt, Christina Rauff Hansen

Patent number: 10398443Abstract: An implantable medical device includes a support structure which is twistable in a longitudinal direction of the device. A sleeve of filter or occluding material is attached to the ends of the structure. The structure in practice twists on itself in the longitudinal direction, causing the sleeve to twist on itself and as a result to close the lumen through the sleeve. The device provides reliable closure and as a result occlusion of a vessel. It is also able to be delivered over a guide wire. In another embodiment, the support structure includes a wire which coils around the sleeve to constrict the sleeve and as a result to close a lumen of the sleeve.Type: GrantFiled: September 8, 2017Date of Patent: September 3, 2019Assignee: Cook Medical Technologies LLCInventors: Tue Thuren Bödewadt, Christina Rauff Hansen, Erik E.

Publication number: 20180369547Abstract: A medical balloon for a balloon catheter is described. The balloon has at least a first layer made from a first material and a second layer made from a second material, said first and second layers being in overlying relationship with one another and being integral with one another; wherein the first layer has a softening or melting temperature which is higher than a softening or melting temperature of the second layer. A method of forming the medical balloon is also described, including locating a raw tubing in a mold; preheating and inflating the raw tubing so as to cause it to stretch; heating the raw tubing to soften or melt the second layer; setting the inflated raw tubing to form the medical balloon; and cooling the set balloon.Type: ApplicationFiled: August 29, 2018Publication date: December 27, 2018Applicant: Cook Medical Technologies LLCInventors: David A.

Patent number: 10111671Abstract: A delivery system (50) for a detachable medical device (10) comprises a first helical wire (12) attached to the medical device, a second helical wire (18) attached to a deployment member (16) and a wire coil (30) which is arranged to interconnect the helical wires (12, 18). A pull on a release wire (32) at one end of the coil (30) detaches the coil from at least one of the helical wires whereby to detach the medical device (10) from the deployment member (16). In a modification a release coil (130) is arranged between concentric helical wires (112, 118).Type: GrantFiled: March 14, 2013Date of Patent: October 30, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventor: Tue Thuren Bodewadt

Patent number: 10092295Abstract: A vascular occluder includes a tubular support element and a sleeve of occluding material disposed within the support element. The sleeve is twisted in the support creating a constriction which closes the lumen of the sleeve. The lumen of the sleeve can nevertheless be opened by a guide wire or cannula for over the wire delivery. Once the guide wire or cannula are withdrawn from the sleeve, the sleeve will close again by the action of blood pressure thereon. Blood pressure will act to maintain closing pressure on the sleeve, thereby avoiding or reducing the risk of recanalization.Type: GrantFiled: April 30, 2015Date of Patent: October 9, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Tue Thuren Bödewadt, Christina Rauff Hansen, Kim Møgelvang Jensen, Raimo Urban Jensen, Erik E.

Publication number: 20180250010Abstract: A filamentary occlusion assembly includes a longitudinal filamentary element of biocompatible material, such as small intestine submucosa. To provide the filamentary element with both longitudinal rigidity and radiopacity, a pliable radiopaque wire is wound around the filamentary element. It is wound such that spaced radiopaque marker regions are formed by winding the radiopaque wire with a small pitch. These are separated by spacer sections where the radiopaque wire is coiled with a much greater pitch. The filamentary occlusion assembly can be delivered using a small diameter catheter to fill an aneurysmal sac.Type: ApplicationFiled: March 5, 2018Publication date: September 6, 2018Inventors: Aidan P.

Patent number: 10022128Abstract: A vascular occluder includes first and second conical members disposed in opposing relation and which have tooth-shaped wide ends. The conical members are coupled to one another by a coupling element, which may be a cannula or rod. The conical members are formed of a membrane which has a thickness which increases towards the narrow ends and decreases towards the toothed elements. The toothed elements are preferably self-supporting within a vessel and avoid folds within the occluder membrane, which may otherwise result in leakage of blood around the device. The device may be provided with a supporting frame which may be at least partially embedded within the membrane. The membrane is preferably made of silicone.Type: GrantFiled: January 15, 2016Date of Patent: July 17, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Tue Thuren Bödewadt, Christina Rauff Hansen

Publication number: 20180193608Abstract: A guide wire assembly for medical use includes at least a portion which is formed of a plurality of inter-cooperating elements forming a flexible section of the guide wire assembly, and specifically a section that can have varying flexibility. A control device passes through a lumen extending for the whole length of the guide wire and is typically fixed at a distal end of the assembly. The control device is used to change the flexibility of the guidewire assembly and in some embodiments to lock it in position. The elements have tapering internal lumens for accommodating the control device, particularly when the guide wire is bent.Type: ApplicationFiled: January 11, 2018Publication date: July 12, 2018Applicant: Cook Medical Technologies LLCInventors: Tue Thuren Bödewadt, Palle Munk Hansen

Publication number: 20160166259Abstract: A vascular plug for implantation into a patient's vessel includes an inflatable balloon and a flow accelerator. The flow accelerator includes a conical portion and a tubular coupling element which couples the conical portion to an aperture to the interior of the inflatable balloon. The flow accelerator will concentrate and therefore accelerate fluid flow into the inflatable balloon. Flow accelerator will increase the pressure of fluid thereby to cause the inflatable balloon to inflate even within a pressurised blood vessel. The plug may include a sleeve which provides a chamber between the flow accelerator and the balloon, into which blood may pass from the inflatable balloon or the flow accelerator to create additional blood statis and as a result thrombosis and a second occlusive barrier.Type: ApplicationFiled: December 15, 2015Publication date: June 16, 2016Inventors: Tue Thuren Bödewadt, Christina Rauff Hansen
