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.

1. A tissue sample retrieval and preservation system, comprising: a tissue removal device configured with an outer cannula having an outer cannula opening for receiving tissue, an inner cannula disposed in the outer cannula, wherein the inner cannula distal end cooperates with the outer cannula open
1. A tissue sample retrieval and preservation system, comprising: a tissue removal device configured with an outer cannula having an outer cannula opening for receiving tissue, an inner cannula disposed in the outer cannula, wherein the inner cannula distal end cooperates with the outer cannula opening to sever tissue samples;a tissue collector operatively connected to the tissue removal device and a vacuum generator, wherein the vacuum generator is configured to transport tissue samples severed by the tissue removal device to the tissue collector through the inner cannula, the tissue collector including an open distal end, a body section and having a fitting member formed on a proximal end of the tissue collector that substantially closes the proximal end of the tissue collector; anda temperature control sleeve having a substantially closed proximal end face with an access opening through which the fitting member may extend when the temperature control sleeve is mounted to the tissue collector such that the proximal end face is disposed around a proximal end of the tissue collector, wherein the temperature control sleeve is disposed at least partially about the by section of the tissue collector to control the temperature of the tissue samples disposed within the tissue collector. 2. The tissue sample retrieval and preservation system of claim 1, wherein the temperature control sleeve is configured with a body portion having an open distal end. 3. The tissue sample retrieval and preservation system of claim 2, wherein the body portion of the temperature control sleeve is configured with a continuous periphery configured to conform to an outer contour of the tissue collector. 4. The tissue sample retrieval and preservation system of claim 1, wherein the temperature control sleeve is in direct contact with the tissue collector. 5. The tissue sample retrieval and preservation system of claim 1, wherein the temperature control sleeve is constructed as a thermal conductor. 6. The tissue sample retrieval and preservation system of claim 1, wherein the temperature control sleeve is configured as a flexible sheet configured to be selectively wrapped around and retained about an outer surface of the tissue collector. 7. The tissue sample retrieval and preservation system of claim 1, wherein the temperature control sleeve includes electrically powered cooling elements operatively connected to a power source. 8. The tissue sample retrieval and preservation system of claim 1, wherein the temperature control sleeve includes a temperature material sandwiched between outer layers, wherein the temperature of the material may be heated or cooled prior to the temperature control sleeve being disposed on the tissue collector. 9. The tissue sample retrieval and preservation system of claim 1, wherein the tissue collector further comprises a normally closed and selectively removable cap member covering one end of the tissue collector. 10. The tissue sample retrieval and preservation system of claim 9, wherein the cap member includes a sleeve portion that is configured to frictionally engage an outer surface of the tissue collector, wherein the sleeve portion is configured to be selectively disengaged from the tissue collector. 11. The tissue sample retrieval and preservation system of claim 1, wherein the tissue collector is remotely connected to the inner cannula. 12. The tissue sample retrieval and preservation system of claim 11, further comprising a preservation adapter system positioned between the inner cannula and the tissue collector, wherein the preservation adapter system is configured to deliver fluid to the severed tissue samples within the tissue collector via the generation of vacuum. 13. The tissue sample retrieval and preservation system of claim 12, wherein the preservation adapter system comprises a body portion defined by first and second ends and an inlet port that intersects the body portion between the first and second ends, wherein the first end is fluidly connected to inner cannula and the second end is fluidly connected to the tissue collector. 14. The tissue sample retrieval and preservation system of claim 13, wherein the inlet port is defined by an inner diameter than is smaller than an inner diameter of the body portion so as to control the rate of fluid being introduced to the tissue collector. 15. The tissue sample retrieval and preservation system of claim 13, wherein the inlet port further includes a valve that is configured to be open and draw fluid through the inlet port when the vacuum generator is operated. 16. The tissue sample retrieval and preservation system of claim 12, wherein the fluid is one containing a solution containing nutrients and a solution for preserving tissues. 17. The tissue sample retrieval and preservation system of claim 1, wherein the tissue collector further comprises a filter body and wherein the filter body is disposed in the tissue collector, the filter body configured to retain samples therein, while permitting fluids to pass through the filter body. 18. The tissue sample retrieval and preservation system of claim 17, further comprising a selectively slidable scoop member disposed within the filter body, the scoop member configured to remove tissue samples from the filter body, when the scoop member is removed from the filter body. 19. The tissue sample retrieval and preservation system of claim 1, further comprising a fluid supply sleeve that comprises an outer cannula channel and at least one fluid supply channel, wherein the outer cannula channel is disposed about the outer cannula and the fluid supply channel is configured to provide fluid to a target site along a pathway that is parallel to an axis extending through the outer cannula. 20. The tissue preservation system of claim 1, wherein the tissue collector is sealed closed from atmospheric exposure. 21. The tissue preservation system of claim 1, wherein the tissue collector includes tubing that is fixedly connected to the fitting member of the tissue collector, wherein a proximal end of the tubing includes a connector element that is configured to be selectively connected to a distal end of the tissue collector to selectively seal the tissue collector when disconnected from the tissue removal device. 22. The tissue preservation system of claim 21, further comprising a coupler mounted to the distal end of the tissue collector, wherein the coupler includes a tube fitting member to which the connector element connects to the distal end of the tissue collector.
