Patent number: 10420675Abstract: A balloon catheter is used in a closed-loop heat exchange system for manipulating the temperature of a patient. The balloon catheter is positioned in the stomach of the patient, and then expanded with a heat exchange fluid delivered through a lumen formed in the shaft of the catheter. The balloon catheter comes into contact with the wall of the stomach, and the stomach substantially conforms around the expanded balloon catheter. The heat exchange fluid is allowed to flow continuously into and out of the balloon catheter. Heat is exchanged between the balloon catheter and the stomach so as to controllably alter the temperature of at least a portion of the patient. Anti-shivering mechanisms and automatic control based on temperature feedback from the patient may be used in connection with the heat exchange system.Type: GrantFiled: June 22, 2017Date of Patent: September 24, 2019Assignee: Zoll Circulation, Inc.Inventor: Paul M. Stull

Publication number: 20160228291Abstract: Systems and methods for accurate temperature modification of a patient, or selected regions thereof, including inducing hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette attached to the circulatory flow lines of the catheter, the heat exchange cassette being sized to engage a cavity within a control unit. A temperature measurement scheme for obtaining body core temperature is provided, including methods of obtaining and analyzing temperature data to provide feedback to the control unit for use in controlling the heating and cooling of the heat exchange medium so as to heat or cool a patient to a desired target temperature.Type: ApplicationFiled: April 18, 2016Publication date: August 11, 2016Applicant: ZOLL CIRCULATION, INC.Inventors: Jeffrey Calliser, Paul M.

Publication number: 20120253120Abstract: The invention is directed to an endoscopic assembly having an endoscope, particularly a flexible hysteroscope and an outer sheath disposed about a length of the shaft of the hysteroscope which has an expandable member such as an inflatable balloon for sealing the assembly within a body lumen or cavity. Specifically, the endoscope assembly is configured for delivery of an occlusive contraceptive member to the patient's fallopian tube. The invention is also directed to an endoscope having a driving member for movement of a medical device within the working lumen of an endoscope. In one embodiment the driving member is a friction wheel which engages an elongated medical device disposed within the working channel of the endoscope to effect longitudinal movement of the medical device.Type: ApplicationFiled: June 15, 2012Publication date: October 4, 2012Inventors: Jeffrey P.
