STEM CELL DELIVERY DEVICE FOR ORTHOBIOLOGICS APPLICATIONS
First Claim
1. An apparatus for thawing and delivery of biological material, comprising:
- a housing defining an interior space;
a thermoelectric heating element mounted in said interior space and having a heating surface configured to receive biological material container;
a squeezing apparatus mounted in said interior space and operable to exert a squeezing force on a biological material container received at the heating surface of said thermoelectric heating element; and
a control for applying power to said thermoelectric heating element so as to warm biological material within the biological material container and to operate said squeezing apparatus so as to deliver the warmed biological material from the biological material container.

Abstract
A method and apparatus for thawing and delivery of cryogenically frozen biological material, such as stem cells includes a housing for receiving a pouch of frozen cells, a heating element against which the pouch is placed for applying defrosting heat to the pouch, and a squeezing apparatus for applying a squeezing force to the pouch after or upon thawing of the cells. The squeezing force may be applied by a roller pressing the pouch against the heating element, which forces the thawed cells from a needle or tube connected to the housing and/or to the pouch. A rechargeable battery in the housing supplies power to the heating element and the squeezing apparatus.

8. A method for delivering frozen biological materials, comprising the steps of:
-
inserting a container of frozen biological materials into a delivery device in thermal contact with a heating element; applying a heat to the container of frozen biological materials to thaw the biological materials; applying a squeezing force on the container while the container is in thermal contact with the heating element; and delivering thawed biological materials from the container. - View Dependent Claims (9, 10, 11, 12, 13)

14. An apparatus for delivery of frozen biological material, comprising:
-
a housing having a conical first end and a second end, said conical first end defining a delivery opening; a pivotably openable portion of the housing; a thermoelectric heating element having a flat heating surface and mounted within an openable portion of the housing, the flat heating surface being configured to receive a pouch of frozen biological material and being operable to apply heat to the pouch; a roller mounted within the housing and disposed to receive a pouch of frozen biological material between said roller and said heating element; a motor operably connected to said roller and operable to rotate said roller so as to cause the roller to squeeze the pouch of biological material; and a deliver conduit extending from said delivery opening of said conical first end of said housing through which the biological material is delivered upon application of squeezing force by the roller on the thawed biological material in the pouch.
