Abstract
Abstract A method of shaping polymeric structures by coating a support structure with a bond-preventing agent to attain a particular shape and subsequently coating the shaped structure of the bond-preventing agent with a polymeric bonding composition is provided. Such shaped polymeric structures can have one or more cavities which can be fluid-filled or gel-filled. Also provided is a hand-actuating retention female urinary catheter having an inner tube and an outer overcoat layer encircling the tube with an elastomeric collar with a shroud. A cavity containing a fluid is interposed between the tube and the overcoat layer. The cavity includes a balloon portion and a reservoir portion. The shroud encircles the reservoir section to inhibit the ballooning of the reservoir section when the reservoir section is squeezed to force fluid from the reservoir portion to the balloon portion through the sleeve portion of the cavity. The overcoat layer and the collar with a shroud are made of soft resilient material.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
268 words
A hand-actuated retention catheter, comprising: a tube having a proximal end and a distal end, the tube having outer and inner surfaces, the inner surface defining an inner lumen, an overcoat layer encircling the tube, the overcoat layer having interior and exterior surfaces, a cavity interposed between the tube and the overcoat layer, said cavity encircling the tube and being defined by portions of the outer surface of the tube in cooperation with portions of the interior surface of the overcoat layer, a fluid within the cavity, a restriction means and a means for limiting the lateral ballooning of the reservoir section; wherein the overcoat layer includes an expandable, resilient balloon section proximate a distal end, the fluid reservoir section proximal thereto, and a catheter sleeve section interconnecting said balloon section and said reservoir section, each of the sections corresponds to a corresponding section of the catheter; the cavity including a balloon portion, a fluid reservoir portion, and a catheter sleeve portion thereof interconnecting said balloon portion and said reservoir portion; the catheter sleeve section of the overcoat layer defines a narrowing in the cavity through which fluid passing from the fluid reservoir portion and the balloon portion thereof must pass; the restriction means encircling the sleeve section to restrict the flow of fluid from the balloon portion to the fluid reservoir portion of the cavity, and the means for limiting lateral ballooning encircling the reservoir section to limit the lateral ballooning thereof, said means for limiting lateral ballooning not substantially restricting the flow of fluid from the balloon portion to the fluid reservoir portion of the cavity.
Claim 2
Dependent Claim
268 words
A hand-actuated retention catheter, comprising: a tube having a proximal end and a distal end, the tube having outer and inner surfaces, the inner surface defining an inner lumen, an overcoat layer encircling the tube, the overcoat layer having interior and exterior surfaces, a cavity interposed between the tube and the overcoat layer, said cavity encircling the tube and being defined by portions of the outer surface of the tube in cooperation with portions of the interior surface of the overcoat layer, a fluid within the cavity, a restriction means and a means for limiting the lateral ballooning of the reservoir section; wherein the overcoat layer includes an expandable, resilient balloon section proximate a distal end, the fluid reservoir section proximal thereto, and a catheter sleeve section interconnecting said balloon section and said reservoir section, each of the sections corresponds to a corresponding section of the catheter; the cavity including a balloon portion, a fluid reservoir portion, and a catheter sleeve portion thereof interconnecting said balloon portion and said reservoir portion; the catheter sleeve section of the overcoat layer defines a narrowing in the cavity through which fluid passing from the fluid reservoir portion and the balloon portion thereof must pass; the restriction means encircling the sleeve section to restrict the flow of fluid from the balloon portion to the fluid reservoir portion of the cavity, and the means for limiting lateral ballooning encircling the reservoir section to limit the lateral ballooning thereof, said means for limiting lateral ballooning not substantially restricting the flow of fluid from the balloon portion to the fluid reservoir portion of the cavity.
Claim 3
Dependent Claim
24 words
The catheter of claim 1 wherein the restricting means is a restrict collar and the means for limiting lateral ballooning is a cylindrical shroud.
Claim 4
Dependent Claim
16 words
The catheter of claim 2 wherein the collar and the shroud are unitarily and integrally connected.
Claim 5
Dependent Claim
16 words
The catheter of claim 2 wherein the collar and the shroud are made of silicone rubber.
Claim 6
Dependent Claim
40 words
The catheter of claim 1 wherein the restriction means and the means for limiting lateral ballooning are capable of being removed from the catheter by being pulled to slip along the catheter direction toward the proximal end of the tube.
Claim 7
Dependent Claim
17 words
The catheter of claim 1 wherein the tube and the overcoat are made with a silicone rubber.
Claim 8
Dependent Claim
21 words
The catheter of claim 6 wherein the silicone rubber overcoat has 20-40 durometer hardness and a wall thickness of 0.1-1 mm.
Claim 9
Dependent Claim
30 words
The catheter of claim 6 further comprising a stylet, a portion of which is removably disposed in the inner lumen of the tube for urging the catheter during deployment thereof.
Claim 10
Dependent Claim
15 words
The catheter of claim 1 wherein said tube has an opening proximate the distal end.
