Device and method for depositing tissue on a scaffold

摘要

A biological tissue collection device is provided having a housing (12) with a fluid-retaining inner chamber adapted to retain a bioimplantable, fluid permeable tissue scaffold (16a). 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 (14a) and a second chamber (14b). The collection device further includes a driver mechanism (18) 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. <IMAGE>
