Patent number: 7896870Abstract: A catheter includes a cryoablation tip with an ablation assembly for heating tissue. The cryoablation tip may be implemented with a cooling chamber and have an RF electrode at its distal end. The electrode may be operated to warm cryogenically-cooled tissue, or the coolant may be controlled in combination with an RF treatment regimen to enhance the lesion size, speed or placement of multi-lesion or single lesion cycles. In one embodiment a microwave energy source operates to extend beyond the thermal conduction depth, or penetrate the ice ball and be absorbed in tissue beyond an ice boundary, thus extending a dimension of treatment. Also, the cooling and application of RF energy can be controlled to position the ablation region away from the surface contacted by the electrode thereby leaving surface tissue unharmed while ablating at depth or to provide an ablation band of greater uniformity with increasing depth.Type: GrantFiled: September 10, 2007Date of Patent: March 1, 2011Assignee: Medtronic Cryocath LPInventors: Steven G.

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.

Patent number: 6730077Abstract: A cryocatheter for treatment of tissue has a tip adapted to provide a signal indicative of the quality and/or orientation of the tip contact with surrounding tissue. In one embodiment, a signal conductor extends through the catheter to the tip and connects to a thermally and electrically conductive shell or cap that applies an RF current to the region of tissue contacted by the tip. The tissue impedance path between the signal lead and a surface electrode mounted on the patient's skin is monitored to develop a quantitative measure of tissue contact at the distal tip, which is preferably displayed on the screen of a catheter monitoring console. In yet a further embodiment, the catheter is provided with a split tip having temperature monitoring sensors, such as thermistors, mounted on opposed halves of the tip so as to sense temperature on two sides of the catheter axis.Type: GrantFiled: September 9, 2002Date of Patent: May 4, 2004Assignee: CryoCath Technologies Inc.Inventors: Sean Carroll, George Klein, Marwan Abboud, Steven G.
