摘要： A system and method for electrical stimulation of a body tissue. An array of microneedles, formed from an electrically conductive material are adapted for puncturing a surface of the tissue. A processing unit is configured to determine from a signal when the microneedles in the microneedle array are in a predetermined position in the tissue or when tissue surrounding one or more microneedles has been ablated.

摘要： An access needle is provided. The access needle includes a needle housing and a needle shaft having a portion disposed within the needle housing. The access needle also includes a lumen within the needle shaft, an entry port at a proximal end of the needle shaft, and a needle tip at a distal end of the needle shaft. The access needle also includes an exit port on a sidewall of the needle shaft, wherein the exit port is disposed nearer the distal end of the needle shaft than the proximal end, and wherein the lumen extends from the entry port to the exit port. The exit port a reduced diameter from the needle shaft. Guide surfaces in the vicinity of the exit port help to reduce snagging or drag of the guide wire. The access needle tip can be formed from nitinol and the guide surfaces can be formed from UV or AB glue. A system and a method for using the access needle are also provided.

摘要： A method of manufacturing a surgical instrument that includes an energized feature operable to apply ultrasonic energy or RF energy to tissue. The method includes forming at least one of a microscopic surface pattern or a nanoscopic surface roughness into a base surface of the energized feature to produce at least one recessed portion. The method also includes applying a hydrophobic coating that includes at least one of silicone, titanium nitride, chromium nitride, or titanium aluminum nitride to at least the recessed portion of the energized feature after forming at least one of the microscopic surface pattern or the nanoscopic surface roughness.

摘要： Apparatuses and methods are disclosed for the perforation of a communication between the aorta and left atrium. The method includes introducing the apparatus, positioning the apparatus at a location along the aorta, and energizing the apparatus to create a perforation. For example, one method may include: introducing a flexible wire into the left atrium, advancing a dilator along the flexible wire to position the flexible wire adjacent a selected location along the aorta and energizing the flexible wire to create a perforation from the left atrium into the aorta.

摘要： A robotic surgical instrument comprising: a shaft; an end effector comprising a first end effector element with a first surface and a second end effector element with a second surface configured to interface with the first surface; and an articulation connecting the end effector to the shaft, the articulation permitting the first end effector element to rotate about a first axis and the second end effector element to rotate about a second axis, the first and second axes being transverse to the longitudinal axis of the shaft; wherein, when the end effector is aligned with the shaft and the first and second surfaces are interfaced, the orientation of the first surface, relative to the first axis, is greater than zero degrees.

摘要： A medical device for treating coronary artery disease, peripheral arterial disease or varicose veins includes an elongated support and a heat expandable element of muscle polymer carried on that elongated support. The medical device may also include a heating element. When activated, the heating element produces heat that causes the muscle polymer to expand into a position in closer proximity to the tissue to be treated.

摘要： An electrosurgical instrument including an end effector assembly having first and second jaw members and at least first and second thermal cutting elements. Each of the first and second jaw members includes an electrically conductive tissue contacting surface. At least one of the first or second jaw members is movable relative to the other from a spaced apart position to an approximated position to grasp tissue between the tissue contacting surfaces. The first and second jaw members are adapted to connect to a source of energy for electrosurgically treating tissue grasped between the tissue contacting surfaces. Each of the first and second thermal cutting elements is disposed on or within one of the first or second jaw members and adapted to connect to a source of energy for thermally treating tissue.

摘要： An apparatus includes a shaft, a balloon, a tip member, and a heating feature. The tip member is distal to the balloon and has a larger outer diameter than the shaft. The heating feature is operable to ablate tissue of the Eustachian tube contacting the balloon in the expanded state. The heating feature may include an illuminating element and a photosensitive coating on the balloon. Alternatively, the heating feature may include a thermal heating element that heats the balloon inflation fluid and thereby heats the wall of the balloon. Another apparatus includes a shaft, a tip member, and an electrode assembly. The electrode assembly includes a plurality of electrodes positioned along the shaft near the distal end, proximal to the tip member. The electrodes are spaced apart from each other along a longitudinal axis and are operable to apply RF energy to tissue to thereby ablate the tissue.

摘要： Devices, systems and methods are provided for delivering pulsed electric field (PEF) energy to tissue through one or more energy delivery bodies, each having one or more electrodes. The PEF energy is generated from a waveform having a variety of features. Waveform delays, such as inter-pulse delays, inter-cycle delays, inter-phase delays, inter-packet delays, inter-bundle delays, may be utilized within a treatment to obtain a desired outcome. In particular, these delays may be specifically manipulated to obtain particular desired outcomes. For example, one, some or all of these delays may be manipulated to control various aspects of PEF therapy so as to mitigate any associated risks, such as gas formation, electrical discharge, cavity formation, muscle contraction, and temperature rise, to name a few. In some embodiments, the delays distribute the period over which PEF energy is delivered, resulting in marked changes and optimization to the treatment delivery outcomes.
