Abstract:
1. A biological tissue collection device, comprising: a housing having a fluid-retaining inner chamber with a bioimplantable, fluid permeable tissue scaffold disposed therein such that the scaffold separates the fluid-retaining inner chamber into a first chamber and a second chamber, wherein the second chamber includes an overflow mechanism located just distal to the scaffold and effective to allow any excess fluid disposed within the second chamber to be released; a driver mechanism coupled to the housing and effective to create a force within the housing to displace fluid disposed within the second chamber to the first chamber and thereby disperse any biological tissue deposited on the tissue scaffold within the fluid, wherein removal of the force enables the fluid to return to the second chamber and thereby deposit the biological tissue onto the tissue scaffold; and a jet plate disposed within the second chamber and movable between an original position, in which the jet plate is positioned a distance apart from the first chamber, and a second position, in which the driver mechanism applies a force that causes the jet plate to move toward the first chamber, the jet plate being adapted to agitate fluid disposed within the second chamber as the jet plate moves between the original position and the second position such that biological tissue is uniformly deposited onto the tissue scaffold.
