Tissue collection device and methods
First Claim
1. A biological tissue collection device, comprising:
- a proximal housing defining an inner proximal chamber configured to retain fluid therein;
a distal housing defining an inner distal chamber configured to retain fluid therein, the distal housing being removably matable to the proximal housing such that the proximal and distal chambers are in fluid communication with one another;
a retaining member having upper and lower portions attached by a hinge and configured to engage a tissue scaffold therebetween, the retaining member being removably disposed between the proximal and distal chambers such that a scaffold engaged by the retaining member separates the proximal and distal chambers; and
a driver mechanism coupled to the proximal housing and configured to create a force to draw fluid from the distal chamber through a scaffold engaged by the retaining member and into the proximal chamber, and wherein release of the force allows the fluid to flow from the proximal chamber through the scaffold and back into the distal chamber;
wherein the distal housing includes a transverse slot formed therein for slidably receiving the retaining member and the retaining member includes opposed locking tabs configured to interface with ridges formed on an outer surface of the distal housing to secure the retaining member between the proximal and distal chambers.

Abstract
A biological tissue collection device is provided having a housing with a fluid-retaining inner chamber adapted to retain a bioimplantable, fluid permeable tissue scaffold. The scaffold is preferably retained in the housing in such a way that the scaffold separates the fluid-retaining inner chamber into a first chamber and a second chamber. The collection device further includes 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. As the fluid is displaced, any biological tissue deposited on the tissue scaffold is dispersed within the fluid. Removal of the force enables the fluid to return to the second chamber and thereby deposit the tissue onto the tissue scaffold. In an exemplary embodiment, the tissue is deposited evenly onto the tissue scaffold.
