Abstract: An anti-free-flow mechanism includes an occluder mechanism which is disposed along a segment of tubing and a mounting structure. The occluder mechanism is normally in a biased closed position, but may be moved into an open position by placement in the mounting structure. However, unless force is applied to keep the occluder mechanism in the mounting structure, the occluder will move relative to the mounting structure and return to the first, closed position.

Abstract: An infusion system utilizes a solution reservoir divided into a first section and a second section which are fluidly isolated but volumetrically connected such that introduction of a pumping fluid into the first section of the reservoir causes displacement and flow of a solution out of the second section of the reservoir. The use of a separate reservoir, separation member, and delivery tubing allow for significantly decreased loss of feeding solution and the like due to dead volume.

Abstract: A method for infusing solutions utilizes a solution reservoir divided into a first section and a second section which are fluidly isolated but volumetrically connected such that introduction of a pumping fluid into the first section of the reservoir causes displacement and flow of solution out of the second section of the reservoir. The use of a separate reservoir, separation member, and delivery tubing allow for significantly decreased loss of feeding solution due to dead volume. The solution reservoir can be configured to provide proportionally different flow.

Abstract: An aortic cannula tip for reintroducing blood into the blood stream via the aorta. The tip creates a soft flame-shaped flow pattern that reduces the chances of dislodging atheromatous or adherent thromba from the inside surfaces of the aorta. A gentle tapered shape allows the tip to penetrate a small incision made in the aorta without causing undo trauma or risk of tearing. The tip includes a circumferential ridge that allows the tip to be rotated and/or pivoted while in the aorta without breaking a seal formed between the ridge and the aortal wall. A secondary port provides access to a second lumen useable to deploy an intraaortic filtration system.
