    摘要: A coating for an electrosurgical electrode to reduce the potential for sticking of tissue. The coating is an elastomer containing a plurality of diamond particles having an average diameter of between diameter of 0.5 and 500 nanometers and that comprise between 0.1 and 25 percent by weight of the coating. The coating may be formed by reducing a silicone dispersion with xylene, adding the plurality of diamond particles, and agglomerating the plurality of diamond particles through sonification and then applied to the device. The coasting may also be formed by reducing a silicone dispersion with xylene, adding the plurality of diamond particles, and agglomerating the plurality of diamond particles through sonification, and then applied to the device by plasma enhanced vapor deposition.

    摘要: A wire driver for inserting a wire into bone. The wire driver includes a housing having proximal and distal ends, with a handpiece extending to the proximal end. The handpiece is connected to a gripping portion, which extends to the distal end. A channel extends through the gripping portion and is connected to a gripping mechanism. A drive mechanism within the handpiece is connected to the channel. The drive mechanism is configured to rotate the channel when actuated by a first actuator positioned on the handpiece (which can be on the distal end of the handpiece). A second actuator is connected to the gripping portion and the gripping mechanism. The second actuator is movable between a relaxed position and a compressed position. The user can operate both first and second actuators with the same handpiece grip. The gripping portion and second actuator are rotatable relative to the housing and first actuator.

    摘要: The device includes a proximal delivery catheter having a proximal handle assembly and an elongated catheter body extending distally from the proximal handle assembly. The elongated catheter body defines a longitudinal axis. The proximal delivery catheter includes a drive wire movably positioned within the elongated catheter body, a spring release coupled to a distal end of the drive wire, and a shaft spring positioned radially outward from the spring release. The shaft spring includes an annular portion. The spring release is configured and adapted to abut the annular portion of the shaft spring upon proximal translation of the spring release. The device includes a distal clip assembly removably connected to the distal end of the elongated catheter body. The proximal delivery catheter is configured and adapted to transmit linear motion along the longitudinal axis and torsion about the longitudinal axis to at least a portion of the distal clip assembly.

    摘要: An electrode pad with a defibrillation circuit and a separate ECG tracing circuit. The electrode pad includes a foam base layer, first and second conductive layers, and a hydrogel layer. The foam base layer has a first side and the first conductive layer is centrally located on the base layer. The first conductive layer has a first circuit configured to provide a defibrillation current. The second conductive layer extends at least partially around the first conductive layer on the first side of the base layer. The second conductive layer has a separate second circuit configured to receive an electrical signal. The hydrogel layer covers the first and second conductive layers on the first side of the base layer. The electrode pad additionally includes an electrical connector attached to the first and second conductive layers. The electrical connector is configured for providing a voltage to the first and second conductive layers.

    摘要: A tip for a bone anchor having cutting edges that converge at an end of the body to form a point and thus define a series of cutting faces. The cutting faces can be planar or curved, and can also be multi-faceted. The tip may include a broach that extends parallel or at an angle relative to tip. The broach may be partially or fully interrupted by one of the cutting faces. The tip is designed to be coupled to any variety of bone anchor types, including those with mechanical retention structures, that change shape in response to insertion into a bone, or that have threads for advancing the anchor into a bone. The anchor and the body may be integrally formed together, and the anchor and the body may be formed from different materials.

    摘要: An anchor includes a flat fibrous construct having an open elongated column; and a filament having a first filament end and a second filament end, which passes through and is positioned at least partially in the open elongated column. The flat fibrous construct includes a first state in which the flat fibrous construct is uncompressed and extends along the longitudinal axis of the filament when in an unfolded and pre-deployed condition; and a second state in which the flat fibrous construct is compressed and expanded in a direction perpendicular to longitudinal axis of the filament in a deployed condition.
