  • Publication number: 20230204471
    Abstract: 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.

  • Patent number: 9504247
    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.
