  • Patent number: 10980737
    Abstract: The invention can selectively heat a diseased area in the lung while minimizing heating to the healthy area and surrounding tissue. This is done by exposing the lung to an electromagnetic field causing dielectric or eddy current heating. The invention is particularly useful for treating emphysema as the diseased areas have reduced blood flow. The diseased area will heat up rapidly while the healthy tissue will be cooled by the blood flow. This is particularly effective for treating emphysema because of the low mass of the lungs and the high blood flow. To avoid heating of surrounding organs the direction of the electromagnetic energy is switched in a way it always passes through lungs but only intermittently passes through adjacent organs. If heat activated drugs are present in the lungs, they are selectively released in the heated tissue.

    Abstract: A medical treatment apparatus includes a heat transfer portion, a heating chip, a temperature measurement unit and a control unit. The heat transfer portion comes into contact with a living tissue and transfers heat to the living tissue. The heating chip includes a heating region, is joined to the heat transfer portion, and heats the heat transfer portion by inputting energy to the heating region. The temperature measurement unit acquires a temperature of the heating region. The control unit controls a temperature of the heat transfer portion to a target temperature by controlling the temperature of the heating region to a temperature differing from the target temperature by an offset value which changes in accordance with an amount of the energy.

  • Patent number: 9801585
    Abstract: A catheterization system that includes an electrophysiologic (EP) catheter which has a lumen receiving an electrically conductive fluid delivered by a hydraulic line that is acted upon by a peristaltic pump advantageously avoids noise in intracardiac ECG signal recordings by using an electrical connection to short triboelectrical charge carried by the conductive fluid in the hydraulic line to an existing analog ground in the system. In one embodiment, the electrical connection includes an electrically conductive wire housed in the control handle and configured to provide electrical connection between the fluid and a pin on a printed circuit board housed in the control handle that is electrically connected to the analog ground. In another embodiment, the electrical connection shorts the electrically conductive fluid proximal of the control handle of the catheter.

  • Patent number: 9408622
    Abstract: Various embodiments are directed to articulatable surgical instruments. Some embodiments comprise an end effector to treat tissue, where the end effector comprises an ultrasonic blade. A hollow shaft may extend proximally from the end effector along a longitudinal axis. A waveguide may extend through the shaft and may be acoustically coupled to the ultrasonic blade. The waveguide may comprise a distally positioned flange positioned within the hollow shaft proximally from the blade and may be held stationary at a first pivot point positioned within the hollow shaft proximally from the flange. A reciprocating wedge may be positioned within the hollow shaft such that distal motion of the wedge pushes the wedge between the flange and the hollow shaft, causing the ultrasonic blade to pivot about the first pivot point in a first direction.

  • Patent number: 9295570
    Abstract: A method of making a stent delivery system is provided in which a delivery catheter has a balloon that extends non-uniformly into interstices of a stent. In accordance with the method a balloon/stent/crimping tube assembly is placed in a crimping tool, the balloon is inflated, and the crimping tool is actuated to compress the stent on the outside of the balloon without application of heat or chemicals, thereby causing creases of the balloon to extend non-uniformly into the interstices of the stent. Optionally, pillows may be formed in the balloon to prevent longitudinal movement of the stent with respect to the balloon during intravascular delivery. One or more secondary crimpings also may be performed to achieve a smoother delivery profile.

  • Patent number: 9179963
    Abstract: Regions of tissue having reduced electrical propagation are created in a bladder to affect its electrical or mechanical properties. To create these tissue regions, a tubular device is advanced through the urethra leading to the interior of the bladder, a distal expandable structure of the device is expanded to contact the inner wall of the bladder, and electrodes or other active energy delivery elements of the device are activated to deliver ablation energy. The electrodes or other active energy delivery elements are disposed over the expandable structure which is shaped to conform to the interior of the bladder. The inner wall of the organ is ablated in a predetermined pattern. The same or other electrodes disposed over the expandable structure can used to electrically map the bladder. This map of electrical activity can be used to create the predetermined pattern.
