Patent number: 9314589Abstract: A method of treating an intravascular site in a patient includes spraying jets of treatment fluid out of spray orifices formed in an elongate catheter body, and changing an impingement pattern of the treatment fluid on material within the intravascular site in response to a torque induced by a back pressure of the jets. A thrombolysis catheter includes an elongate catheter body having a plurality of spray orifices formed in a body wall, and communicating with a fluid lumen longitudinally extending in the elongate catheter body. The plurality of spray orifices define a torque inducing spray jet pattern, whereby a back pressure of spray jets exiting the spray orifices induces a torque on the elongate catheter body.Type: GrantFiled: May 3, 2011Date of Patent: April 19, 2016Assignee: Cook Medical Technologies LLCInventors: Therese O'Day, Frank J. Fisher, Lindsay Koren, Mark Allen Magnuson, Richard Earl Luedemann, Shyam Kuppurathanam, Keith R. Milner

Patent number: 9205224Abstract: An infusion mechanism for treating an intraluminal site in a patient includes an infusion catheter having an elongate body with a proximal body end defining at least one fluid supply orifice, and a distal body end. The elongate body defines a high head loss lumen in fluid communication with a first set of side ports defining a proximal infusion zone. The elongate body further defines a low head loss lumen in fluid communication with a second set of side ports defining a distal infusion zone.Type: GrantFiled: April 8, 2010Date of Patent: December 8, 2015Inventors: Therese O'Day, Frank J. Fischer, Jr., Lindsay Koren, Mark Allen Magnuson, Richard Earl Luedemann, Shyam Kuppurathanam, Keith R. Milner

Patent number: 8574218Abstract: A catheter includes an elongate catheter body having an outer surface with a non-uniform contour and including a plurality of maximum surface elevation points and a plurality of minimum surface elevation points defining a non-uniform elevation profile relative to a longitudinal axis of the catheter body. The outer surface further includes a fluid transfer interface which includes the plurality of minimum surface elevation points and a plurality of porous surface areas, and a tissue contact interface which includes the plurality of maximum surface elevation points and a plurality of nonporous surface areas. The tissue contact interface inhibits external occlusion of the fluid transfer interface during transferring fluid between a fluid lumen defined by the elongate catheter body, and an intraluminal space such as an intravascular space within a patient.Type: GrantFiled: May 10, 2010Date of Patent: November 5, 2013Assignee: Cook Medical Technologies LLCInventor: Therese O'Day

Patent number: 8568369Abstract: An infusion catheter includes an elongate catheter body having a proximal body component and a distal body component. The distal body component includes a distal body outer surface and a distal body inner surface defining an infusion lumen. The distal body component further includes a skeleton, and a porous infusion control textile contacting the skeleton and extending circumferentially about a longitudinal axis of the catheter and defining a fluid emission profile thereof. The porous infusion control textile further includes a fiber network having a higher density space filling configuration at a proximal textile end and a lower density space filling configuration at a distal textile end, and defining a pressure sensitive flow rate property and a pressure insensitive flow distribution property of the fluid emission profile.Type: GrantFiled: August 5, 2010Date of Patent: October 29, 2013Assignee: Cook Medical Technologies LLCInventors: Therese O'Day, Richard Earl Luedemann, Shyam Kuppurathanam
