    Abstract: A cardiac valve prosthesis including an armature for anchorage of the valve prosthesis at an implantation site. The armature defining a lumen for the passage of the blood flow and having a longitudinal axis, and a set of prosthetic valve leaflets supported by said armature and configured to move, under the action of blood flow, in a radially divaricated condition to enable the flow of blood through said lumen in a first direction, and in a radially contracted condition, in which said valve leaflets co-operate with one another and block the flow of blood through the prosthesis in the direction opposite said first direction. The armature including an annular part and a pattern of arched struts carried by said annular part, said pattern of arched struts having proximal ends connected to said annular part, and distal ends spaced axially from the proximal ends and opposite said annular part, a plurality of sets of anchoring formations configured to protrude radially outwardly of said annular part, each set being supported by at least one of said annular part and a corresponding arched strut, and a plurality of support posts, each support post being supported by adjacent arched struts, wherein the sets of anchoring formations alternate with the support posts around said longitudinal axis.

    Abstract: Described is a gas exchanger with a restriction element or elements to reduce gas exchange as desired to avoid hypo-capnia and hyper-oxygenation in small patients. The gas exchanger includes a gas exchanger housing with an outer wall and a core which defines an inner wall and having a blood inlet for receiving a blood supply and a blood outlet. The gas exchanger also includes: a hollow fiber bundle disposed within the housing between the core and the outer wall; and a gas inlet compartment for receiving an oxygen supply and directing the oxygen supply to first ends of the hollow fiber bundle, wherein the gas inlet compartment includes at least one restriction element configured to allow the oxygen supply to reach only a portion of the hollow fiber bundle.

    Abstract: An autotransfusion system for separating fluid constituents includes a centrifuge housing and a rotatable driving member mounted within the centrifuge housing. The rotatable driving member is configured to receive therein and rotationally engage any one of a plurality of centrifuge bowls with different heights. In some embodiments, the centrifuge bowl is integrated with a fluid line organizer to provide for easy and efficient organization of a plurality of different fluid lines incorporated into the autotransfusion system. In some embodiments, the centrifuge bowl and fluid line organizer are easily and efficiently coupled to the centrifuge housing for autotransfusion processing. After autotransfusion processing, the centrifuge bowl and fluid line organizer are easily and efficiently decoupled from the centrifuge housing and discarded.

    Abstract: A system includes a fluid reservoir, a differential pressure sensor, and a controller. The fluid reservoir has a bottom and is to hold a fluid. The differential pressure sensor is coupled to the bottom of the fluid reservoir and to sense a pressure difference between pressure exerted on the differential pressure sensor by the fluid and pressure exerted on the fluid in the fluid reservoir and to provide at least one signal that indicates a fluid level in the fluid reservoir. The controller is to receive the at least one signal and determine a fluid volume in the fluid reservoir based on the at least one signal. Also, the controller is to provide at least one of a fluid level signal that indicates the fluid level in the fluid reservoir and a fluid volume signal that indicates the fluid volume in the fluid reservoir.

    Abstract: A blood reservoir may be used in combination with other elements such as a heart lung machine (HLM), oxygenator, heat exchanger, arterial filter and the like to form an extracorporeal blood circuit that may be employed in a procedure such as a bypass procedure. The blood reservoir may be configured to receive, filter and store blood from a number of sources including vent blood (from within the heart), venous blood (from a major vein), purge blood (from a sampling line) and cardiotomy or suction blood (from the surgical field).

    Abstract: A heart valve prosthesis includes an expandable prosthetic valve including three valve leaflets coupled to an anchoring structure. The anchoring structure includes an annular member and a plurality of arms movably coupled to the annular member at one end. The free ends of the arms extend radially away from the prosthesis toward a valve annulus. The arms are configured to fit in a space defined between an open native valve leaflet and a wall of a valve sinus. The arms are sufficiently resilient such that they resist downward movement in response to pressure exerted on the prosthesis, facilitating anchorage and stabilization of the prosthesis at the implantation site.
