The jaws members are connected to a source of electrical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. At least one non-conductive and spaced-apart stop member is disposed on an inner-facing surface of the jaw members to regulate the gap distance between the jaw members when tissue is held therebetween. The forceps also includes a longitudinally reciprocating knife which severs the tissue after sealing at a location which is proximate the sealing site.

  • Patent number: 10682172
    Abstract: The preferred embodiment provides apparatus for ablating a vessel by generating heat within a vessel to cause blood clotting to occlude the vessel. The apparatus includes an electrically resistive element at the distal end of the apparatus, the resistive element being uncoated and therefore in bare form. An alternating current supply feeds electrical current through the resistive element to cause heating of the element and surrounding blood or tissue. The alternating current power supply preferably is balanced about a centre point so as to create a net sum of alternating pulses of zero. It has been found that the supply of alternating current to the resistive element reduces or eliminates corrosion of the resistive element in blood as the resistive element is heated. Use of conductive coatings for a sacrificial anode can be avoided.

  • Patent number: 10646666
    Abstract: Described herein are cryolipolysis devices, systems, and methods for facilitating percutaneous access to a target blood vessel by performing cryolipolysis on subcutaneous adipose tissue obscuring the target blood vessel (e.g., a vessel used for hemodialysis treatment). Generally, the devices include a cooling member carrying a coolant that cools a selected portion of adipose tissue overlying the target blood vessel to reduce the selected portion of adipose tissue, thereby forming a depression in the adipose tissue and allowing the target blood vessel closer to the surface of the skin. In some variations, the cooling member is placed subcutaneously to directly cool the selected portion of adipose tissue. In other variations, the cooling member is placed external to the patient to indirectly cool the selected portion of adipose tissue through the skin.
