METHODS AND DEVICES FOR TISSUE COLLECTION AND ANALYSIS
First Claim
1. A biopsy device for collecting a tissue sample comprising:
- a coring needle having an internal lumen; and
a cryogenic probe removable and translatably disposed within said internal lumen;
wherein said cryogenic probe is translated into said internal lumen to draw a tissue into said internal lumen and said cryogenic probe preserves and adheres to said tissue.

Abstract
The present invention is directed to methods and devices for tissue collection and analysis, and particularly to methods and devices for collecting, preserving and analyzing biopsy samples. In one aspect, a method for collecting a tissue sample includes disposing a collection device proximate and/or within a tissue, such as of a body, drawing in at least a portion of the tissue into the collection device, adhering the at least a portion of the tissue to at least a portion of the collection device and separating the sample and collection device from the remainder of the tissue and/or body. In general, the method of adhering the tissue sample to the collection device may also preserve the tissue sample, such as, for example, by altering the temperature of the tissue sample. In one embodiment, the method of adhering the tissue sample to the collection device includes lowering the temperature of the collection device and thus the tissue sample such that the tissue sample may adhere to the collection device and may also be preserved against degradation.
