An endoscopic bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The forceps also includes a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal. A generally tube-like cutter is included which is slidably engaged about the elongated shaft and which is selectively movable about the elongated shaft to engage and cut tissue on at least one side of the jaw members while the tissue is engaged between jaw members.

An energy treatment device includes: a base having electrical conductivity and including a treatment surface for applying a high-frequency current to a treatment target when being supplied with electrical energy. A coating, including a silane coupling agent having a coupling structure, is formed over at least the treatment surface of the base by a bond due to the coupling structure; and an organic layer is disposed between the treatment surface of the base and the coating, and is bonded to the surface of the base. The coupling structure of the coupling agent of the coating is bonded to the organic layer.

A device for creating an arteriovenous (AV) fistula includes a proximal base having a distal tapered end surface and a distal tip connected to the proximal base and movable relative to the proximal base. The distal tip has a proximal tapered end surface. A first heating assembly, including an energized heating element, is disposed on at least one of the distal tapered end surface and the proximal tapered end surface. A second heating assembly, comprising a passive non-energized heat spreader, is disposed on the other one of the distal tapered end surface and the proximal tapered end surface. The distal tapered end surface and the proximal tapered end surface are adapted to contact opposing sides of a tissue portion to create the fistula. The taper of the proximal tapered end surface matches the taper of the distal tapered end surface, so that the two surfaces match one another.

A laser system, laser fibers, and associated methods are disclosed. In one example, the devices include a hydrophobic coating with a hydrophobic nanoscale physical structure.

An electrode for an electrosurgical pencil, the electrode comprising an elongated body made of a conductive material and extending in an axial direction from a proximal end to a distal end, the proximal end configured for engaging the electrosurgical pencil and the distal end forming a blade configured for cutting or coagulation of tissue by electrosurgical energy received from the pencil, the blade being defined by two main surface portions on opposite sides of an axially extending intermediate plane and joined by an edge extending through the intermediate plane. To concentrate electrical energy at the edge and thereby facilitate a more precise cutting and less burnt tissue sticking to the electrode, the main surface portions has a first surface roughness, the edge has a second surface roughness being lower than the first surface roughness, and at least the main surface portions are covered by a surface coating comprising silicone.

An endoluminal energy delivery device includes a proximal end and a distal end, an electrically conductive core extending from the proximal to the distal end, and an energy delivery tip at the distal end. The energy delivery tip includes a distal core portion and an electrically conductive element disposed coaxially around the distal core portion and electrically coupled thereto in parallel. The distal core portion is made of a first material and the electrically conductive element is made of a second material. The second material has a higher conductivity than the first material. Electrical energy supplied to the delivery device passes simultaneously through the distal core portion and the electrically conductive element.

Various embodiments disclosed relate to a lubricant. The lubricant includes a first non-amphiphilic triglyceride. The lubricant further includes a second non-amphiphilic triglyceride. The second non-amphiphilic triglyceride is different from the first non-amphiphilic triglyceride. The lubricant further includes a non-amphiphilic glycol ester.
