Abstract
A system for selectively preventing free flow in a tube includes an in-line occluder disposed in the tube and an actuator pad for creating a flow path between the tube and the occluder. The actuation pad presses towards the occluder from a single side and stretches the tube to create a large flow path. The occluder stem is strengthened to resist deformation and damage from the forces applied by the actuator pad.
Claims24
An in-line occluder comprising:
- a flexible tubing having a bore;
- an occluder disposed in the bore, the occluder comprising:
- a body;
- an occluding portion, the occluding portion having a round cross-section and engaging the bore of the tubing to seal against the tubing and prevent flow past the tubing;
- and
- a stem connecting the body to the occluding portion, the stem having a ‘T’ shaped cross section.

An occluder system comprising:
- a flexible tubing having a lumen;
- an occluder comprising:
- a body;
- a stem having a first end and a second end, the first end being attached to the body;
- and
- an occluding portion attached to the second end of the stem and spaced apart from the body, the occluding portion being disposed in the lumen of the tube and having a round cross-section with a diameter greater than the diameter of the lumen;
- an actuator pad, the actuator pad comprising:
- two projections;
- and
- an actuation channel disposed between the two projections;
- and
- wherein the actuation pad selectively engages the tubing on one side of the tubing to create a flow passage between the occluding portion and an opposite side of the tubing.
