Patent number: 9888953Abstract: A cryotherapy system includes a cryotherapy catheter having an inflatable balloon portion and a pressure regulator. The inflatable balloon portion includes an outer balloon and an inner balloon within the outer balloon. The inner balloon is configured to receive during a cryotherapy procedure a cryogenic agent for extracting heat from body tissue at a desired location. The inflatable balloon portion is at a distal end of the cryotherapy catheter. The pressure regulator is adapted to maintain a positive pressure between the inner balloon and the outer balloon during a cryotherapy procedure.Type: GrantFiled: May 14, 2015Date of Patent: February 13, 2018Assignee: Boston Scientific Scimed, Inc.Inventors: Frank Ingle, Rebecca Tin, Robert F. Bencini, James Mazzone

Patent number: 9872717Abstract: In some implementations, a method of ablating body tissue includes (a) locating an inflatable balloon portion of a cryotherapy balloon catheter at a treatment site internal to a patient's body, and inflating the inflatable balloon portion; (b) employing electrodes that are disposed on an expandable surface of the inflatable balloon portion to electrically characterize body tissue at the treatment site; (c) ablating the body tissue by supplying a cryotherapy agent to the inflatable balloon portion to cool the body tissue to a therapeutic temperature; (d) employing the electrodes to determine whether the ablating caused desired electrical changes in the body tissue; and (e) repeating (c) and (d) when it is determined that the ablating did not cause the desired electrical changes.Type: GrantFiled: June 23, 2015Date of Patent: January 23, 2018Assignee: Boston Scientific Scimed, Inc.Inventors: Robert F. Bencini, Frank Ingle, Josef V. Koblish, Rebecca Tin, James Mazzone, Byron Chun, David Lawrence

Patent number: 8591504Abstract: A cryoablation catheter assembly includes a catheter having a coolant outtake region and receives a guide tube and a coolant transfer tube. The coolant transfer tube receives and transfers coolant from a coolant source to an expansion element coupled to a distal portion of the catheter. The expansion element includes an outer layer disposed over an inner layer such that the expansion element defines an inter-expansion-element space between the inner layer and the outer layer and an intra-expansion-element space within the inner layer. The intra-expansion-element space is in fluid communication with the coolant outtake region and the coolant transfer tube. The inter-expansion-element space is in fluid communication with a fluid pathway that transfers fluids to a fluid-drawing source. A pressure regulation system is disposed along the fluid pathway and passively regulates the pressure in the inter-expansion-element space using at least one check valve.Type: GrantFiled: July 30, 2010Date of Patent: November 26, 2013Assignee: Boston Scientific Scimed, Inc.Inventor: Rebecca Tin
