Patent number: 11780623Abstract: A wire guide includes a solid core mandrel that is initially received in a flat wire coil that has a rest inner diameter that is greater than a uniform diameter of the solid core mandrel. The flat wire of the flat wire coil is in tension between a proximal location and a distal location so that the flat wire coil has a reduced inner diameter that is smaller than its rest inner diameter. The tension in the flat wire is introduced by torquing the mandrel relative to the flat wire coil as part of attaching the coil to the mandrel.Type: GrantFiled: January 18, 2019Date of Patent: October 10, 2023Assignee: Cook Medical Technologies LLCInventors: Kurt J. Tekulve, Andrew Bowers

Patent number: 10433824Abstract: A tubular body for a medical device for insertion within a body passageway of a patient. The tubular body includes a tubular inner liner. A braided member is disposed along an outer surface of the liner. The braided member includes intersecting filaments and cells defined by the filaments. A securement mechanism, such as radiopaque solder, is disposed along a circumferential region of the braided member. The securement mechanism is attached to portions of the filaments and spans the cells that correspond to the circumferential region to inhibit relative movement of filament ends. An outer surface of the securement mechanism is sized to extend radially outward to a position up to an outer surface of the braided member to not add to the overall wall thickness of the tubular body. An outer jacket is positioned longitudinally around the braided member and connected to the inner liner.Type: GrantFiled: October 7, 2016Date of Patent: October 8, 2019Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Mahendran Ravichandran, Kurt J.

Patent number: 10300179Abstract: A medical device for draining a fluid from the body of a patient includes a tubular member having an open distal end that resides interiorly of the body of a patient and a proximal end that extends exteriorly of the body of the patient. The tubular member has an inner surface extending between the distal end and the proximal end, wherein the inner surface defines a lumen. An interior member is disposed in the lumen and extends along a length of the inner surface. The interior member is engaged with the inner surface such that a chamber is defined therebetween. A conduit is engaged with the tubular member for transmission of an inflation fluid to selectively vary a dimension of the chamber for freeing clogged debris in the lumen.Type: GrantFiled: April 4, 2016Date of Patent: May 28, 2019Assignee: Cook Medical Technologies LLCInventor: Kurt J.

Patent number: 9763667Abstract: A system for occluding a blood vessel includes an embolization coil having barbed fibers coupled thereto. The coil can be delivered in a straight configuration and then transition into a larger coiled structure. The barbed fibers can overlap within a lumen defined by the larger coiled structure and attached to each other to define a mesh. The barbs of the barbed fiber can limit the fibers from being pulled out of the coil, as well as provide anchoring of the coil to the blood vessel in which the coil is deployed. The barbed fibers can also be used to anchor two coils to each other.Type: GrantFiled: March 12, 2014Date of Patent: September 19, 2017Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Carrie L.

Patent number: 9724104Abstract: An aneurysm closure clip along with a system and method for use by a physician in delivering the closure clip into the vasculature of a patient is disclosed. The closure clip delivery system comprises a delivery tube in the form of a catheter, a guide wire, and a detachable closure clip. The closure clip includes a proximal side and a distal side. The distal side comprises at least two winged elements that interact with the wall of the body vessel to hold the clip in place after delivery. The proximal side includes a seal element and a guide bar. The guide bar is in communication with the guide wire during delivery. The seal element forms a barrier between the aneurysm and the rest of the body vessel, thereby, reducing any pressure exerted on the aneurysm. The seal element and optionally the winged elements include a material layer comprised of bioremodelable material, such as an extracellular matrix material (ECM).Type: GrantFiled: August 30, 2012Date of Patent: August 8, 2017Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Kurt J.

Patent number: 9554783Abstract: In one embodiment, a device for closing or occluding ASDs and PFOs, or other bodily passageways, includes a circumferential frame, a sheet of biocompatible material attached to the frame, and at least one anchor attached to the sheet of biocompatible material. In another embodiment, the closure device includes a circumferential frame, at least one crossbar extending across and attached to the frame, at least one anchor connected to at least one crossbar; and at least one sheet of biocompatible material (such as ECM material) attached to the frame. The anchor includes at least one grasping member having a structure, such as a wired loop, which is configured for releasable attachment to a delivery release member, which facilitates delivery of a closure device collapsibly disposed in a delivery catheter. Alternatively, one or more anchor end pairs may be connected to a delivery bar enhancing delivery and retrieval of the device.Type: GrantFiled: July 31, 2009Date of Patent: January 31, 2017Assignees: COOK MEDICAL TECHNOLOGIES LLC, OREGON HEALTH AND SCIENCE UNIVERSITYInventors: Dusan Pavcnik, Kurt J.
