Patent number: 10252036Abstract: Thrombus removal apparatus includes a balloon catheter with a short balloon at a distal end thereof. An aspiration catheter is disposed coaxially over the balloon catheter. The balloon catheter includes a plurality of holes for the administration of lytic agent. The apparatus does not seal off completely the zone of the vessel around the thrombus, thereby allowing movement of blood within the vessel. The balloon is shaped so that it can be pulled along the vessel in an upstream direction so as to drag against the vessel walls for assisting in the removal of the thrombus.Type: GrantFiled: December 18, 2012Date of Patent: April 9, 2019Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Steen Aggerholm, Kian Olsen

Patent number: 8123770Abstract: An integrally formed angioplasty cutting device for balloon angioplasty of a stenotic lesion in a body vessel. The device comprises a distal collar and a proximal collar. The device further comprises at least one strut integrally formed with the distal collar and the proximal collar. At least one of the collars has a slot formed therethrough defining a C-shaped configuration. The strut is configured to be disposed at the stenotic lesion to engage the stenotic lesion for dilatation of the body vessel during angioplasty.Type: GrantFiled: November 1, 2006Date of Patent: February 28, 2012Assignee: Cook Medical Technologies LLCInventors: Kian Olsen, Mark J. Hiatt, Michael W. Hardert

Patent number: 8057495Abstract: A system and method for occluding an aneurysm formed in a dilatation area of a body vessel are disclosed. The system comprises a wire guide, a core wire, and an occlusion device. The wire guide comprises a proximal end and a distal end, and has a passageway that extends from the proximal end to the distal end. The core wire comprises a distal end and a proximal end, and is disposed through the passageway so that the proximal end of the core wire proximally extends beyond the proximal end of the wire guide. The occlusion device comprises a distal end and a proximal end, and has a deployed state and an undeployed state. The occlusion device has a pre-set spiraled coil shape when in the deployed state in the vessel. The occlusion device is disposed distally from the core wire in the passageway.Type: GrantFiled: September 12, 2006Date of Patent: November 15, 2011Assignee: Cook Medical Technologies LLCInventors: Dharmendra Pal, Roy S. Collins, Andrew W. Conder, Kian Olsen, Thomas A. Osborne

Publication number: 20110022075Abstract: To prevent a small diameter catheter 10 of soft material from collapsing when being used to aspirate a blood clot 25, the lumen 16 of the catheter contains a longitudinal member 26 having radially-extending fin elements 33. The longitudinal member may itself be a catheter having a lumen 22 through which passes a wire 27 having at its distal end an expandable basket 28 for retrieving the clot.Type: ApplicationFiled: July 22, 2010Publication date: January 27, 2011Applicants: William Cock Europe ApS, Cook IncorporatedInventors: Frank Christiansen, Per Elgård, Anders Ginge Jensen, Kian Olsen, Carsten Skødt

Publication number: 20090171279Abstract: A balloon catheter assembly included a catheter provided with a distal end and a proximal end and at least one inflation lumen in the catheter. The inflation lumen includes a distal end and a proximal end. An inflatable balloon is provided at the distal end of the catheter and in fluid communication with the distal end of said inflation lumen. The proximal end of the inflation lumen is able to be coupled to a source of fluid. A flow controller is coupled between the inflation lumen and the fluid source, the flow controller being adjustable by an operator of the balloon catheter assembly so as to adjust the flow of inflation fluid to the balloon. In one embodiment, the flow controller includes a manually operable control actuator and a plurality of discrete flow configurations provided in the form of flow through holes in the flow controller.Type: ApplicationFiled: December 26, 2007Publication date: July 2, 2009Applicant: COOK INCORPORATEDInventors: John A. Brumleve, Frank J. Fischer, Kian Olsen

Publication number: 20070293935Abstract: An intraluminal stent delivery and deployment system and a method of delivering and deploying an intraluminal stent are described. The stent delivery and deployment system includes a catheter, an expandable stent disposed about a portion of the catheter, and at least one anchoring device attached to the catheter. The anchoring device has a proximal portion disposed distal of a midpoint of the stent. The anchoring device is deployed and engages a body vessel before the stent is expanded to a fully expanded configuration, thereby anchoring at least the catheter to the body vessel during the expansion of the stent.Type: ApplicationFiled: June 5, 2007Publication date: December 20, 2007Applicant: Cook IncorporatedInventors: Kian Olsen, Thomas Osborne, Scott Todd, Jason Urbanski

Publication number: 20060259132Abstract: A method and device to repair a stenosis in a blood vessel is provided. The medical device has a tubular member and a frame. The frame may be expanded or contracted while maintaining its generally cylindrical configuration. The medical device is retained in a contracted state inside an introducer sheath. The introducer sheath is guided through the stenosis such that a first end of the medical device is located distal the stenosis. The introducer sheath is retracted relative to the medical device, such that the first end of the stent expands to engage the blood vessel distal the stenosis. A mid-portion of the medical device engages the plaque of the stenosis trapping any emboli against the wall of the vessel. The second end expands to engage the blood vessel proximal to stenosis.Type: ApplicationFiled: May 1, 2006Publication date: November 16, 2006Applicant: Cook IncorporatedInventors: Darin Schaffer, John Brumleve, Kian Olsen, Ram Paul, Dharmendra Pal, Fred Parker
