  • Patent number: 10675079
    Abstract: This invention relates to a novel surgical device scalable to small dimensions for thermally-mediated treatments or thermoplasties of targeted tissue volumes. An exemplary embodiment is adapted for fusing, sealing or welding tissue. The instruments and techniques utilize a thermal energy delivery means, for example an electrical energy source, to instantly elevate the temperature of a biocompatible fluid media within an electrically insulated instrument portion. The altered media which may then be a gas is characterized by a (i) a high heat content, and (ii) a high exit velocity from the working end, both of which characteristics are controlled to hydrate tissue and at the same time denature proteins to fuse, seal, weld or cause any other thermally-mediated treatment of an engaged tissue volume—while causing limited collateral thermal damage and while totally eliminating electrical current flow the engaged tissue volume.

  • Patent number: 9724116
    Abstract: An endoscopic forceps includes an elongate shaft defining an instrument axis. An end effector includes first and second jaw members each supporting an opposed sealing surface for clamping tissue. At least one of the jaw members is movable relative to the instrument axis such that the jaw members are movable between a first spaced-apart configuration and a second closed configuration for grasping tissue. A cutting instrument includes a reciprocating blade translatable relative to the sealing surfaces to sever tissue clamped between the jaw members. The reciprocating blade contacts an undersurface of at least one of the jaw members when the jaw members are in the second configuration to define a gap distance between the sealing surfaces. A handle adjacent the proximal end of the elongate shaft is operable to induce motion in the jaw members, and an actuator is operable to selectively translate the reciprocating blade.

  • Patent number: 9655668
    Abstract: Apparatus and methods for cooling liquid coolant, such as nitrous oxide, to be delivered to a cryo-ablation device such as a balloon catheter. A hose or conduit in fluid communication with the ablation device includes an outer member and inner tubes. A first inner tube disposed within a lumen of the outer member carries liquid coolant to the ablation device. Another inner tube also disposed within the lumen carries liquid coolant and terminates within the lumen such that gaseous coolant derived from liquid coolant flowing through the second inner tube flows within the lumen to cool or chill the first inner tube and liquid coolant carried by the first inner tube to the ablation device.

  • Patent number: 9642668
    Abstract: 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.

  • Patent number: 9644880
    Abstract: 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.

  • Patent number: 9579144
    Abstract: 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.

  • Patent number: 9561125
    Abstract: 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.

  • Patent number: 9528796
    Abstract: 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.

  • Patent number: 9522244
    Abstract: 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.

  • Patent number: RE46697
    Abstract: 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.).
