Summary for Patent: 6,059,107

Title:	Urinary catheter assembly with a ready-to-use catheter
Abstract:	A urinary catheter assembly comprises a urinary catheter (1) having on at least a part of its surface a hydrophilic surface layer (6) intended to produce a low-friction surface character of the catheter by treatment with a liquid swelling medium prior to use of the catheter and a catheter package (7) having a cavity (11) for accommodation of the catheter (1). The package (7) is made with walls of a gas impermeable material to accommodate a catheter pretreated with said liquid swelling medium for long time preservation of said low-friction surface character and provision of a ready-to-use catheter assembly.
Inventor(s):	N.o slashed.sted; Ulrik (Lyngby, DK), Torstensen; Jan (Virum, DK), Kayer.o slashed.d; Helle (Copenhagen N, DK), Tangh.o slashed.j; Allan (Kokkedal, DK)
Assignee:	Coloplast A/S (DK)
Application Number:	09/297,150
Patent Claims:	1. A urinary catheter assembly comprising at least one urinary catheter (1) having on at least a part of its surface a hydrophillic surface layer (6) intended to produce a low-friction surface character of the catheter by treatment with a liquid swelling medium prior to use of the catheter and a catheter package (7) having a cavity (11) for accommodation of the catheter (1), characterized in that the package (7) is formed with walls made throughout of a gas impermeable material for long time accommodation of said at least one urinary catheter, said catheter having been pretreated with said liquid swelling medium before arrangement in said package for long time preservation of said low-friction surface character during accommodation in said package and provision of a ready-to-use catheter assembly. 2. A urinary catheter assembly as claimed in claim 1, characterized in that the catheter package (7) is formed from two sheets (8, 9) of gas impermeable film material connected with each other by a gas impermeable joint (10) defining the cavity (11) for accommodating the catheter (1). 3. A urinary catheter assembly as claimed in claim 2, characterized in that the catheter package (7) is of a general elongate shape with said joint (10) arranged to define said cavity (11) to accommodate the catheter (1) in a substantially linear orientation. 4. A urinary catheter assembly as claimed in claim 2, characterized in that said joint (10) is arranged to provide said cavity (11) with a cross-section narrowly surrounding the catheter (1). 5. A urinary catheter assembly as claimed in claim 2, characterized in that said joint (10) is a welding joint. 6. A urinary catheter assembly as claimed in claim 5, characterized in that said welding joint (10) comprises a part (10a) at the end of the package remote from a compartment (12) providing a peel-off joint to separate said sheets (8, 9) from each other for withdrawal of said catheter (1) from the package (7). 7. A urinary catheter assembly as claimed in claim 1, characterized in that the catheter (1) is provided with means preventing said swelling medium from getting into contact with internal or external surface parts of the catheter not provided with said hydrophillic coating (6) for an activation period during which said medium is applied to the surface part provided with said hydrophillic coating (6). 8. A urinary catheter assembly as claimed in claim 7, characterized in that said means comprises a film layer (55) of a material soluble by said swelling medium applied to said parts not provided with said hydrophillic coating. 9. A urinary catheter assembly as claimed in claim 1, characterized in that said package includes a bag (52) communicating with the catheter (1) for collection of urine. 10. A urinary catheter assembly as claimed in claim 1, characterized in that said liquid swelling medium is selected from the group consisting of aqueous solution, an isotonic aqueous solution, as isotonic aqueous solution of sodium chloride and sterile water.
