Abstract
Abstract The invention concerns a tubular device for insertion in the urethra after transurethral laser irradiation procedure for temporarily keeping the urethra patent, said device consisting of a material which is biodegradable and/or dissolving in the organism. The device is substantially shorter than the urethra so that it can be totally disposed in the urethra.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
54 words
A tubular device for insertion in the urethra after transurethral laser irradiation procedure for temporarily keeping the urethra patent, characterized in that the device consists of material which is biodegradable and/or dissolving in the organism, and the device is substantially shorter than the urethra so that it can be totally disposed in the urethra.
Claim 2
Dependent Claim
20 words
Device according to claim 1, characterized in that the cross section of the device has substantially circular or elliptic shape.
Claim 3
Dependent Claim
19 words
Device according to claim 1, characterized in that in the wall of the tubular device apertures have been provided.
Claim 4
Dependent Claim
34 words
Device according to any one of claims 1-3, characterized in that the device substantially retains its shape in the urethra for at least about 1-3 weeks, e.g. at least one month, advantageously 3-12 months.
Claim 5
Dependent Claim
48 words
Device according to any one of claims 1-4, characterized in that the device consists of biodegradable and/or dissolving polymer material, such as polyglycolide (PGA), polylactide (PLA), glycolide/lactide mixed polymers, glycolide/trimethylene carbonate mixed polymers, polydioxanone, polyhydroxybutyrate, polyhydroxypropionate, mixtures and copolymers of said polymers, chitin polymers, polyester amides or glycolesters.
Claim 6
Dependent Claim
23 words
Device according to any one of claims 1-5, characterized in that the transurethral laser irradiation procedure is a transurethral prostate laser irradiation procedure.
Claim 7
Dependent Claim
64 words
A therapeutic procedure, the patient being subjected to transurethral laser irradiation, whereafter in the urethra is inserted a tubular device for temporarily keeping the urethra patent, characterized in that in the urethra is inserted a device consisting of material which is biodegraded and/or dissolved in the organism, and which is substantially shorter than the urethra so that it becomes disposed totally within the urethra.
Claim 8
Dependent Claim
53 words
Procedure according to claim 7, characterized in that the patient is subjected to transurethral laser irradiation of the prostate and in the urethra is inserted a tubular device which in the urethra substantially retains its shape at least about a few days to three weeks, e.g. at least one month, advantageously 3-12 months.
