    Abstract: A resizable valve base for a cardiovascular valve assembly that is comprised of the resizable valve base and a valve member that is detachably coupled thereto. The resizable valve base has adjustable dimensions to allow use with both small and large size valve members. The valve base comprises a frame comprised of a plurality of frame sections, and each frame section includes a mounting portion and a pair of arcuate portions extending from opposite sides of the mounting portion. The valve base also includes a plurality of joining elements for joining together the frame sections to define a generally cylindrical opening having a diameter, wherein said plurality of joining elements allow adjacent frame sections to move towards or away from each other in order to modify the diameter of the opening, thereby moving the valve base between a collapsed position and an expanded position.

    Abstract: A system for generating a tissue construct includes a mixing chamber, a piston chamber, a reaction chamber, and a pump. The mixing chamber is configured to receive a hydrogel solution and a cell suspension solution. The piston chamber includes a first piston and is configured to receive a mixture of the hydrogel solution and the cell suspension solution from the mixing chamber. The first piston is configured to push the mixture through one or more capillaries into the reaction chamber. The reaction is configured to receive the mixture and a cross-linking initiator. The pump is configured to move the mixture through the reaction chamber such that the mixture and the cross-linking initiator combine to form an encapsulated cell material.

    Abstract: A system for minimally invasive insertion of a bioprosthetic heart valve. The system includes a collapsible tissue-based valve system, a catheter-based valve delivery system, a surgical platform and a device tracking and visualization system. The collapsible valve system includes: (i) a permanent outer frame (10) that is affixed to the patient using conventional sutures or staples, and (ii) a collapsible valve (20) having a collapsible inner frame (21) that mates with the outer frame (10), and supports valve leaflets (13). The inner frame (21) is moved to a collapsed position and located at the previously installed outer frame (10). The inner frame (21) is then expanded to lock the inner frame (21) to the outer frame (10). The inner frame (21) may be re-collapsed and disengaged from the outer frame (10). A new collapsible valve (20) is then installed, to resume the function of the prosthesis.
