Electrosurgical working end for controlled energy delivery

An electrosurgical working end for automatic modulation of active Rf density in a targeted tissue volume. The working end of the probe of the present invention defines a tissue-engagement surface of an elastomeric material with conductive elements that extend therethrough. In one embodiment, the expansion of the elastomeric material can de-couple the conductive elements from an interior electrode based temperature to modulate current flow. In another embodiment, the elastomeric material can couple and de-couple the conductive elements from an interior electrode based on engagement pressure to modulate current flow

Structure for applying sprayable wound treatment material

The present disclosure relates to surgical instruments, structures and methods for enhancing the properties of tissue to be repaired or joined. According to an aspect of the present disclosure, a surgical stapling apparatus is provided including a wound treatment material dispersion system for delivering wound treatment material to a target surgical site. The dispersion system includes an aperture formed in the anvil assembly oriented to dispense wound treatment material in an outward direction; and a source of wound treatment material in fluid communication with the aperture of the anvil assembly.

Electrosurgical instrument

An electrode assembly for an electrosurgical instrument, comprises a bipolar cutting blade, and fluid supply lines for directing a cooling fluid to the cutting blade, the cutting blade comprising first, second and third electrodes, and electrical insulators spacing apart the electrodes, the fluid supply lines being such that cooling fluid enters the cutting blade via the first electrode, passes through an aperture in the second electrode, and exits the cutting blade via the third electrode.

Electrosurgical instrument

An electrosurgical instrument includes a handpiece, an electrode assembly comprising one or more electrodes attached to the handpiece, and connection means for connecting the handpiece to an electrosurgical generator. The handpiece comprises a housing, fluid supply lines for directing a cooling fluid to and from the electrode assembly, and a pump for driving cooling fluid through the fluid supply lines. The handpiece may also include a fluid reservoir. The pump, the fluid supply lines, and the reservoir are all wholly contained within the housing.

Surgical instrument

An electrosurgical instrument for use in cutting and/or coagulating tissue includes a dielectric material, the dielectric material being positioned in the current pathway between the tissue-treatment regions of first and second electrodes. This can be achieved by providing one or more electrode surfaces coated with a dielectric material having a reactive impedance of less than 3,000 ohms/sq. mm. at 450 kHz. The dielectric coating acts to couple the RF signal into the tissue primarily by capacitive coupling, providing a more even heating of the tissue and the elimination of “hot spot”. Examples of electrosurgical instruments employing such coated electrodes include forceps, scissors or scalpel blade instruments.

Wound closure device

Disclosed is a wound closure device and method for using the same. The wound closure device includes a handle, a body portion extending distally from the handle, a stapling mechanism extending distally from the body portion and a mechanism for supplying electrical energy from an RF power supply to a fastener (e.g. staple) which is associated with the stapling mechanism. In a representative embodiment, the stapling mechanism includes an inner rod member disposed within an elongated outer sleeve and slidably movable therein. The rod member has an enlarged tip for deploying the fastener that is supported adjacent to the tip into body tissue. The wound closure device further includes an actuator mechanism associated with the handle and body portion and configured to facilitate relative movement of the inner rod and the outer sleeve so as to deploy the fastener into body tissue. In alternative embodiments, a second pole of the RF power supply is connected to a conductive ring associated with a vascular introducer.

Orthopedic medical device with unitary components

A cordless medical apparatus suitable for use in orthopedic medical applications is disclosed. The medical device includes a disposable sterile housing having a sleeve, said sleeve being configured to receive an unsterilized motor assembly. The invention further includes a sterile packaging system for enclosing the sterile housing and inserting a non-sterile component in the sterile housing.
