Patent number: 9642668Abstract: This invention relates to the treatment of a patient's lung, for example, a lung exhibiting chronic obstructive pulmonary disease (COPD) and in particular to methods and devices for affecting lung volume reduction, preferably for achieving acute or immediate lung volume reduction following treatment. The lung volume reduction is effected by delivering a condensable vapor at a temperature above body temperature to the desired regions of the patient's lung to damage tissue therein. Blood flow and air flow to the damaged tissue region is essentially terminated, rendering the target region non-functional. Alternative energy sources may be used to effect the thermal damage to the lung tissue.Type: GrantFiled: May 4, 2015Date of Patent: May 9, 2017Assignee: Uptake Medical Technology Inc.Inventors: Robert L. Barry, Brian Thomas Cran, Dean T. Corcoran, Sheldon K. Lee

Patent number: 9644880Abstract: A cooling device and methods of using the cooling device are described. The cooling device includes a flexible, elongated body member having a first end portion and a second end portion, or is adjustable with the first end portion and the second end portion attached, the elongated body member forming an elongated cavity extending substantially between the first end portion and the second end portion, the cavity having a first substance disposed within the cavity. The cooling device further includes at least one rupturable compartment contained within the cavity, the compartment having a second substance disposed within the compartment. The cooling device also includes fastening means disposed on at least one of the first end portion and the second end portion for detachably fastening the first end portion to the second end portion to secure the cooling device around a circumference of a body part.Type: GrantFiled: January 24, 2014Date of Patent: May 9, 2017Inventor: Mastaneh Paul

Patent number: 9579144Abstract: Electrosurgical systems and methods are described herein in which the temperature of a fluid within a body or joint space is determined and/or monitored despite the energy generated during treatment by an ablation probe. One or more temperature sensors are positioned along the probe proximally of the electrode assembly and measure the temperature of an electrically conductive fluid without being overly influenced by the surgical effect occurring proximate the electrode assembly. A controller automatically suspends energy delivery for one or more periods of time while the temperature is monitored.Type: GrantFiled: February 7, 2014Date of Patent: February 28, 2017Assignee: ArthroCare CorporationInventor: Duane W.

Patent number: 9561125Abstract: A system for delivering an implant within a patient is described. The activation of the heater coil causes the degradation, melting or reduction of a component that brings the heater coil into or out of electrical contact with another component, or causes the individual loops of the coil to contact each other, thereby resulting a notable change in resistance in the circuit supplying the heater coil with electricity. A core wire terminates prior to the distal end of the device, allowing for greater flexibility.Type: GrantFiled: April 6, 2011Date of Patent: February 7, 2017Assignee: MicroVention, Inc.Inventors: Heath Bowman, Jake Le, Matthew Fitz

Patent number: 9528796Abstract: An aiming device including a thermoelectric module, a light source and a sight element. The thermoelectric module generates electricity from a thermal gradient, produced from a user's body heat that is transferred to the module. The electricity powers the light source. The light source illuminates a sight element of a projectile shooting device to enhance visibility of the sight element in a variety of ambient lighting conditions, optionally in low light conditions. The aiming device can be mounted to a projectile shooting device. With the aiming device, a user can selectively illuminate a sight element of a projectile shooting device, with the user's own body heat, to assist aiming the projectile shooting device during a shooting activity. The projectile shooting device can be any type of archery bow and/or firearm. Related methods are also provided.Type: GrantFiled: March 11, 2015Date of Patent: December 27, 2016Assignee: Grace Engineering Corp.Inventors: Louis Grace, Jr., Timothy J. Roelens, II

Patent number: 9522244Abstract: A brain cooling apparatus is provided that can circulate a fluid between a containing unit of a brain cooling device and the brain cooling apparatus while maintaining an appropriate pressure of the fluid in the containing unit, and a brain cooling device suitable thereto also is provided. A control device circulates a physiological saline solution between a storage tank and a cuff by driving a first pump in a direction in which the physiological saline solution flows toward the cuff, and driving a second pump in a direction in which the physiological saline solution flows toward the storage tank. In this state, the control device adjusts the rotation speed of at least the second pump, so that the pressure of the physiological saline solution in the cuff becomes a preset target pressure.Type: GrantFiled: February 21, 2011Date of Patent: December 20, 2016Assignees: KAIKEN IKI KABUSHIKI KAISHA, NATIONAL UNIVERSITY CORPORATION OKAYAMA UNIVERSITYInventors: Yoshimasa Takeda, Kiyoshi Morita, Hiroshi Hashimoto, Hidekazu Tsuji, Masatomo Kokubu

Patent number: RE46697Abstract: Methods for (a) preventing hypoxic damage to a potentially transplantable organ or tissue prior to explanation of that organ or tissue from the body of a mammalian transplant donor and (b) preventing rejection of a transplanted organ or tissue in a human or veterinary transplant recipient. The methods comprise placing a heat exchange apparatus in the vasculature of the donor or recipient and using that heat exchange apparatus to cool at least a portion of the body of the donor or recipient to a temperature below normothermia (e.g. below normothermia and sometimes between about 30° C. and about 36° C.).Type: GrantFiled: December 8, 2009Date of Patent: February 6, 2018Assignee: ZOLL Circulation, Inc.Inventor: Kenneth G. Hayes, Jr.
