A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described, as well as 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.

System and method of taking and collecting tissue cores for treatment

Holding arrangements for a surgical access assembly are disclosed. One holding arrangement includes a body portion, an engagement barrel and a retaining member. The retaining member is configured as a hook at a distal end of the body portion and is sized to partially encircle a portion of an outer sheath. The engagement barrel is position on a proximal end of the body portion and is configured to be operatively connected to a surgical holding arrangement.

Holding arrangement for a surgical access system

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.
