Patent number: 8585690Abstract: A cryogenic catheter includes an elongate, contiguous, thermally-transmissive region coupled to the catheter, the thermally-transmissive region being sufficiently flexible to change from a linear configuration to an arcuate configuration. The thermally-transmissive region may include a plurality of interconnected thermally-transmissive segments that are generally cylindrical in shape. The cryogenic catheter may be in fluid communication with a fluid source, and may include one or more fluid injection tubes. Further, an injection tube may be slidably disposed within the catheter so that the injection tube is longitudinally movable relative to an outer surface of the catheter. The cryogenic catheter may also be in communication with a controller programmed to regulate delivery of a cryogenic fluid from the fluid source to the medical device.Type: GrantFiled: September 21, 2011Date of Patent: November 19, 2013Assignee: Medtronic CryoCath LPInventors: John W.

Patent number: 7912554Abstract: A method is disclosed for treating an aneurysm or vascular defect by cooling a target tissue region of the aneurysm or vascular defect to a temperature below body temperature for a preselected time period. The method entails thickening, strengthening, or increasing the density of a blood vessel wall by cooling the blood vessel wall with a cryogenically cooled device. The method also includes irradiating the inner wall of a blood vessel around an aneurysm or vascular defect with various forms of energy to delay or halt aneurysm or vascular defect formation. An energy-emitting element is disposed on the distal end portion of a catheter device to be disposed proximate the aneurysm. Various forms of energy, including visible light energy, laser light energy, ultrasound, microwave and radiofrequency sources may be used to irradiate and treat the aneurysm.Type: GrantFiled: April 29, 2005Date of Patent: March 22, 2011Assignee: Medtronic CryoCath LPInventors: Leonilda Capuano, Daniel Nahon, Michael Urick, Willard W.

Patent number: 7648497Abstract: An elongated catheter device with a distal balloon assembly is adapted for endovascular insertion. Coolant injected through the device may, in different embodiments, directly cool tissue contacting the balloon, or may cool a separate internal chamber. In the first case, the coolant also inflates the balloon, and spent coolant is returned to the handle via a return passage extending through the body of the catheter. Plural balloons may be provided, wherein a secondary outer balloon surrounds a primary inner balloon, the primary balloon being filled with coolant and acting as the cooling chamber, the secondary balloon being coupled to a vacuum return lumen to serve as a robust leak containment device and thermal insulator around the cooling chamber. Various configurations, such as surface modification of the balloon interface, or placement of particles, coatings, or expandable meshes or coils in the balloon interface, may be employed to achieve this function.Type: GrantFiled: October 6, 2005Date of Patent: January 19, 2010Assignee: Medtronic Cryocath LPInventors: Miriam Lane, Leonilda Capuano, David Holtan, Jean-Pierre Lalonde, Claudia Lückge, Jean-Luc Pageard, Marwan Abboud, Johnny Al Asmar, Abderrahim Benrabah, Ken Chen, John W.

Publication number: 20050182365Abstract: A method and apparatus for detecting plaque proximate an area of a human body is described, the method comprising the steps of moving one or more electrically sensitive sensors substantially near an area where plaque may be present, obtaining electrical signal readings from the sensors, and determining the presence or absence of plaque. The presence or absence of the plaque corresponds to the electrical signal readings. Another aspect of the invention provides a method for inhibiting plaque formation and passivating plaque formed on a lumenal surface of a body lumen. A cooling device is positioned at the lumenal surface at a point proximate to a plaque formation. The lumenal surface is cooled at the point proximate to the plaque formation to inhibit the progression of plaque formation in which the lumenal surface is cooled to a temperature of less than about zero degrees Celsius. As another aspect, a method is provided for reducing the risk of plaque rupture in a vessel.Type: ApplicationFiled: April 15, 2005Publication date: August 18, 2005Inventors: Willard Hennemann, Michael Urick, Domenic Santoianni, Claudia Luckge, Sean Carroll, Dan Wittenberger, Teresa Mihalik
