Patent Images
1. A catheter for insertion into a patient, said catheter comprising:
- a) at least a partially collapsible elongated elastomeric tube wherein the tube is thin enough to remain in a state of collapse at all times and which is open at a proximal end and substantially closed at a distal end, the distal end of said tube having at least one opening;
b) valve means at the proximal end of said elastomeric tube; and
c) actuation balloon means along said tube for at least partially collapsing or partially stiffening said elastomeric tube when inserted in the patient.

Abstract
A collapsible catheter is provided for use with an inflatable stiffening or reinforcing member which is capable of being inflated with fluid. The catheter comprises a collapsible hollow elastomeric tube which is open at the proximal end. The distal end portion has at least one aperture. A valve is provided which is at the open end of the elastomeric tube. The valve permits access to inflate the stiffening member. The catheter can be used for draining and aspirating urinary tract or draining or feeding the gastro-intestinal tract.

26. A collapsible catheter comprising:
-
a) a collapsible hollow elastomeric tube which is closed at one end and open at the other end, said elastomeric tube having at least one aperture at the closed end; b) a spiral non-distensible hollow tube substantially along the entire inner length of said elastomeric tube, said spiral non-distensible hollow tube stiffening or reinforcing said elastomeric tube when injected with fluid; c) valve means connected to said elastomeric tube at the open end of said tube, said valve means having an opening for access to said spiral non-distensible hollow tube; d) a balloon member outside of said elastomeric tube and attached thereto; and e) actuation means for inflating and deflating said balloon member. - View Dependent Claims (27, 28, 29, 30)
