Patent number: 9987461Abstract: A hemodialysis catheter with a plurality of umbrella-like wire members covered with a film which works as a thrombus blocker and can easily and effectively remove the thrombus is disclosed. The hemodialysis catheter has a proximal lumen, the arterial lumen, and a distal lumen, the venous lumen. An elongate member is longitudinally put in either the proximal lumen or the distal lumen, or two elongate members in both lumens. A plurality of umbrella-like wire members are connected to the end of the elongate member. When the hemodialysis catheter is put in the vessel but not in use, the end of the lumen is capped off by the plurality of umbrella-like wire members covered with a film. When it is ready to use, the doctor can pull the elongate member which connects to the plurality of umbrella-like wire members out off the lumen inverting the plurality of umbrella-like wire members and clearing away any thrombus that has formed.Type: GrantFiled: October 13, 2010Date of Patent: June 5, 2018Assignee: Cook Medical Technologies LLCInventors: Michael W.

Patent number: 9700287Abstract: Among other things, there are disclosed embodiments of full-core biopsy needles having an outer needle component and a middle cannula through a lumen in the outer component, through which a mandrel may be placed. The outer component includes an internal boss that reduces its internal diameter, and the cannula includes fingers that extend distally. When the needle is inserted for biopsy, tissue enters the outer component and cannula. Moving the cannula forward causes the fingers to engage a surface of the internal boss, resulting in the fingers curving into the tissue. The fingers pinch the tissue while reducing or eliminating compression of the sample to provide an easier removal of the tissue from adjacent tissue, as well as providing a block or backstop keeping the tissue within the needle. Gaps are provided between the fingers to further reduce damage to the tissue sample.Type: GrantFiled: May 26, 2016Date of Patent: July 11, 2017Inventors: Thomas W. McGhie, Michael W. Hardert

Patent number: 9192747Abstract: A balloon catheter is provided that may be used to dilate hardened regions of a stenosis. The balloon catheter is provided with dilation elements that extend along a surface of a balloon. The dilation elements may comprise a coil and dilation wire. The coil and wire may be configured in various ways such that inflation of the balloon creates a concentration of forces along the dilating wires which are thereafter transmitted to stenosed regions of a vessel wall. The force exerted by the dilation elements against the stenosed region is sufficient to fracture plaque from the vessel wall.Type: GrantFiled: October 16, 2012Date of Patent: November 24, 2015Assignee: COOK MEDICAL TECHNOLOGIES LLCInventor: Michael W.

Publication number: 20150157332Abstract: Certain aspects of the present invention provide devices for occluding vascular vessels. In some preferred forms, these devices are able to move from a first condition to a less compact, second condition in a vascular vessel so as to fully or partially prevent fluid from passing through the vessel. One such device includes a frame and a flexible sheet material. The device also includes an occluding material that is located in an interior region of the frame. The flexible sheet material and frame are associated with one another such that when the device is in the second condition in the vascular vessel, the sheet material is positioned in the vessel lumen so as to block fluid flow through the lumen.Type: ApplicationFiled: February 17, 2015Publication date: June 11, 2015Inventors: F.
