Patent number: 9504247Abstract: 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.Type: GrantFiled: January 17, 2013Date of Patent: November 29, 2016Assignee: Nico CorporationInventors: Joseph L.
