Catheter
First Claim
1. A catheter for draining fluid from an internal cavity, the catheter comprising:
- an outer tube including an inlet end portion;
a stop formed on the inlet end portion and movable between collapsed and deployed orientations; and
a diagnostic port disposed on said outer tube proximate a bottom of said stop for permitting fluid from the internal cavity to enter said outer tube via said diagnostic port when said stop is disposed in the collapsed orientation to verify that said stop is positioned within the internal cavity before said stop is deployed.

Abstract
The catheter includes an outer tube with an inlet end portion and a stop formed on the inlet end portion. The stop, which normally assumes a collapsed orientation, is moveable between a collapsed orientation and a deployed orientation. The catheter may include at least one of a diagnostic port disposed on the outer tube proximate the bottom of the stop, a locking device proximate the bottom of the catheter for securing the stop in the deployed orientation, and an actuator for operatively moving the stop between collapsed and deployed orientations. Applying force to the actuator moves the stop from the collapsed orientation to the deployed orientation. The actuator may also include a fail-safe mechanism designed to fail when a predetermined amount of force is applied to the actuator.

24. A catheter for draining fluid from an internal cavity, the catheter comprising:
-
an outer tube including an inlet end portion;
a stop formed on the inlet end portion and movable between normal collapsed and deployed orientations;
an actuator to operatively move said stop between the collapsed and deployed orientations, wherein a first end of said actuator connects to a tip of said inlet end portion; and
wherein said stop normally assumes a collapsed orientation but is moveable to a deployed orientation upon actuation of said actuator. - View Dependent Claims (25, 26, 27, 28)

29. A method of administering a catheter comprising:
-
inserting an inlet end portion of an outer tube into an internal cavity of a patient until a stop formed on the inlet end portion is disposed within the internal cavity, said stop movable between collapsed and deployed orientations;
deploying said stop in the internal cavity by pulling an actuator attached to a tip of said inlet end portion and extending through a locking device; and
locking said stop in the deployed orientation by locking said actuator in said locking device. - View Dependent Claims (30, 31, 32, 33, 34, 35)
