Abstract: A syringe pump including a syringe including a plunger that slides in a body which has a discharge port, a driving mechanism coupled to the syringe, including a cylinder in which a piston slides, and a plurality of biasing devices arranged about the piston operative to apply urging forces on the piston to drive the piston distally in the cylinder and thereby cause the plunger to slide in the body and discharge a substance found in the body through the discharge port, wherein if one of the biasing devices fails another of the biasing devices continues to apply a force on the piston to drive the piston distally in the cylinder, and a safety catch that initially prevents the biasing device from moving the piston, the safety catch being removable to permit the biasing device to move the piston.

Abstract: An insemination device including a sperm reservoir including sperm therein, a pump in fluid communication with the sperm reservoir and operative to pump sperm therefrom, and a filter in fluid communication with the pump adapted to filter the sperm to form a sperm filtrate that has a higher fertility potential than the sperm before being filtered by the filter, wherein the filter includes a multi-layer membrane for sperm filtration, including at least one first layer with a shape and pore size for preliminary filtration of relatively large particles and at least one second layer with a shape and pore size for filtration of relatively smaller particles.
