A perfusion catheter system comprises a main line, a first branch line having a tip at a distal end thereof, and a second branch line having a tip at a distal end thereof. The tip of the first branch line is heavier than the tip of the second branch line. The tip of the first branch line may be weighted. There may be a self-inflating balloon at the tip of the first branch line. There may be a self-inflating balloon at the tip of the second branch line. There may be a clamp disposed along the second branch line. The clamp may include a base, a clamping arm hingedly connected to the base, and an aperture extending through the base. The second branch line may extend through the aperture in the base.

Perfusion catheter system for simultaneous delivery of cardioplegia to the left and right coronary artery

A artificial ventricle comprises an inlet for receiving blood, an outlet for discharging blood, and a chamber disposed between the inlet and the outlet. There is also a mechanism for actuating the artificial ventricle between an expanded configuration and a contracted configuration. In the expanded configuration, blood flows into the inlet. In the contracted configuration, blood flows out of the outlet. There may be a one-way valve at the outlet for preventing blood flow back into the chamber. The one-way valve may be a diaphragm valve. The chamber may have a resilient outer wall. The chamber may have an ovoid shape.

Artificial ventricles

A cardiotomy suction tube system comprises a main line, a first flexible branch line in fluid communication with the main line, a second flexible branch line in selective fluid communication with the main line, and a rigid branch line in selective fluid communication with the main line. A valve mechanism selectively places either the second flexible branch line or the rigid line in fluid communication with the main line. The first flexible branch line may be provided with a weighted suction tip which gravitates to a low point in an operative field. The second flexible branch line may be provided with a weighted suction tip which gravitates to a low point in an operative field.

Cardiotomy suction tube system with multiple tips

A ventricle assist device comprises an inlet for receiving blood, an outlet for discharging blood, and a chamber disposed between the inlet and the outlet. There is also a means for actuating the ventricle assist device between an expanded configuration and a contracted configuration. In the expanded configuration blood flows into the inlet. In the contracted configuration blood flows out of the outlet. There may be a one-way valve at the outlet for preventing blood flow back into the chamber. The one-way valve is a diaphragm valve. The chamber may have a resilient outer wall. The chamber may have an ovoid shape.
