METHOD OF SHAPING STRUCTURES WITH AN OVERCOAT LAYER INCLUDING FEMALE URINARY CATHETER

摘要

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 (16) which can be fluid-filled or gel-filled. Also provided is a hand-actuating retention female urinary catheter (5) having an inner tube (12) and an outer overcoat layer (14) encircling the tube with an elastomeric collar (50) with a shroud (51). A cavity (16) containing a fluid (18) is interposed between the tube (12) and the overcoat layer (14). The cavity includes a balloon portion (24) and a reservoir portion (22). The shroud (51) encircles the reservoir section (22) to inhibit the ballooning of the reservoir section when the reservoir section is squeezed to force fluid (18) from the reservoir portion (22) to the balloon portion (24) through the sleeve portion (34) of the cavity. The overcoat layer (14) and the collar (50) with a shroud (51) are made of soft resilient material.
