1. 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

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.

13. 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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
