Abstract: An electro-surgical bipolar forceps includes a first tip and a second tip, each having a body. The body has a distal end and a proximal end. The body has a first groove having a substantially planar base proximate the proximal end. A substantially planar face is proximate to the distal end of the tip body. The base and the face on each tip define planes that are approximately perpendicular with respect to each other. A tip assembly includes a tip and an engagement plug. When making the tip assembly, a planar surface on the engagement plug is aligned with the planar base of the groove in the tip. Then the tip is connected to the engagement plug.

Abstract: Disclosed herein is a method comprising inclining a spray gun of a high velocity oxygen fuel device at an angle of 15 degrees to a perpendicular to a substrate; incrementally displacing the spray gun to an angle of 35 degrees to the perpendicular to the substrate; spraying a surface of the substrate with the spray gun during the displacing of the spray gun; and covering the substrate with a coating that has a smooth transition zone from a coated region of the substrate to a non-coated region of the substrate; wherein the coating provides erosion protection greater than or equal to that of a coating produced when the spray gun spray angle to the substrate is not varied during the spraying.

Abstract: A resealable ventriculostomy reservoir device is provided. The device includes a base having an upper and lower opening, the upper opening defining an internal reservoir well, and a cap having an open bottom portion. The device further includes a flange element having a first portion disposed within a portion of the cap and a second portion extending distally beyond the open bottom portion of the cap and adapted for detachably mating with the internal reservoir well of the base. The second portion of the flange element includes a snap fit element adapted to cooperate with a feature on the internal reservoir well to secure the flange element and the base together. A sealing element is disposed between the internal reservoir well and the flange element to provide a fluid tight seal between the base and the flange element when the base and the flange element are detachably mated.

Abstract: This invention relates to a mixing and delivery device suitable for delivering injectable biomaterials, and to preferred bone cement formulations.

Abstract: In accordance with a currently preferred exemplary embodiment, the present invention involves an electro-surgical bipolar forceps having a first member, a second member, and a tip assembly. The first member has a first insert tube extending from a distal end thereof and a handle disposed at a proximal end thereof. The second member has a second insert tube extending from a distal end thereof and a handle disposed at a proximal end thereof. At least one of the first and second insert tube has an inner surface, a portion of which is covered with an electrically insulating material. The first tip assembly has a proximal end and a distal end. The proximal end of the first tip assembly is selectively engageable with one of the first and second insert tubes. The first tip assembly includes an electrically conductive tip disposed at the distal end of the first tip assembly.
