Abstract: Multiple surgical devices that may be used during surgical procedures are shown and described herein. A surgical device includes an outer cannula and an inner member that has a pair of electrodes positioned at a distal end. The inner member defines an aspiration delivery channel with an opening. The inner member further defines a pair of electrode channels within which the electrodes are positioned. A handle assembly actuates the outer cannula relative to the inner member, thereby adjusting a size of the opening of the aspiration delivery channel. An irrigation hub is provided to deliver irrigation through the surgical device to the electrode channels.

An irrigation annulus is formed about the electrodes. The shaft member further includes at least one lumen opening at the distal end of the shaft member.

Abstract: A surgical access assembly is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath is defined by an open distal end and an open proximal end and includes a hollow body portion therebetween. The obturator is defined by a distal end and a proximal end and the distal end further comprises a tapered distal tip member that terminates in a closed radiused distal tip. The obturator is configured to be received within the outer sheath such that the tapered distal tip member protrudes from the open distal end of the outer sheath when the obturator is in an introducing configuration.

Abstract: A cooling system for preserving tissue is disclosed. The cooling system comprises a base member, a temperature control sleeve constructed of a thermally conductive material, and a selectively removable lid member. The base member defines a reservoir and receives the temperature control sleeve. The temperature control sleeve at least partially defines a tissue collector chamber that is configured to receive a tissue collector. The temperature control sleeve is in communication with the reservoir. The reservoir is configured to receive a cooling medium. A slit formed within the tissue collection chamber that is sized to receive a tubing connected to the tissue collector therethrough. The lid member is configured to be selectively attached to the base member, and permit access to a tube mount for the tissue collector when the lid is attached to the base member.

The obturator is configured to be received within the outer sheath such that the tapered distal tip member protrudes from the open distal end of the outer sheath when the obturator is in an introducing configuration. The outer sheath further includes a gripping member, wherein the gripping member includes at least one retaining notch formed on an outer surface thereof.

Abstract: A holding arrangement for a surgical access assembly is disclosed. One holding arrangement includes a holder member and a support member configured to engage with the holder member. The support member supports an outer sheath of a surgical assembly. The support member is compatible with a magnetic resonance imaging device. Another holding arrangement includes a holder member configured to hold a medical or diagnostic device such as a catheter.

Abstract: A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described. The device includes a handpiece and an outer cannula in which a reciprocating inner cannula is disposed. The inner cannula includes a hinge between a body section and a cutting section that allows the cutting section to pivot when the inner cannula reciprocates within the outer cannula. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. A fluid supply sleeve is disposed about the outer cannula and is selectively positionable along the length of the outer cannula.

Abstract: A tissue cutting device is described that may include alternative systems for tissue preservation and transport. The cutting device includes an outer cannula in which a reciprocating inner cannula is disposed. A tissue collector is also provided and is in fluid communication with the lumen of the inner cannula. A temperature control sleeve may be disposed around the tissue collector to control the temperature of the tissue samples. A preservation system may be supplied that is configured to deliver fluids to tissue samples in the tissue collector. A fluid supply sleeve may be disposed about the outer cannula and is selectively positionable along the length of the outer cannula.

Abstract: An illuminating ring assembly is disclosed. The illuminating ring configured to be used with a surgical access element. The illuminating ring assembly comprises a housing defined by a cover and a wall member extending from the cover, wherein the cover and wall member cooperate to define a cavity therein, a light element configured to be disposed with the cavity, and an attachment mechanism configured to selectively attach the housing to a surgical access element. Wherein the cover and the light element both include an opening therethrough.

Abstract: Adapters for properly positioning a portion of a medical instrument that is positioned within an endoscope at site of interest is disclosed.
