Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 204 words
A disposable therapeutic sound for use in the dilation of the urethra comprising: a base having an opening and engagement means, a hollow elongated tube attached to said base in communicating relationship with said latter opening, said tube having a body provided with a curved end portion terminating in a rounded end, said tube also provided with a plurality of openings communicating with said opening of said base through said hollow body of said tube, an elastic and expandable finger-like covering having an opening and fitting snugly over said body and rounded end of said tube, the periphery of said opening of said latter cover secured circumferentially to said base, the circumference of said covering ranging from 8 mm to 40 mm, a reservoir containing sterilized fluid having an end provided with an opening and engagement means, said reservoir separably secured to said base by the engagement of both of the aforesaid engagement means, said reservoir also in fluid communication with said tube, means for applying pressure to said reservoir causing said fluid to flow through said opening of said Reservoir into said hollow elongated tube and out through said orifices of said tube into said expandable covering expanding the same and said urethra.
Claim 2
Dependent Claim 204 words
A disposable therapeutic sound for use in the dilation of the urethra comprising: a base having an opening and engagement means, a hollow elongated tube attached to said base in communicating relationship with said latter opening, said tube having a body provided with a curved end portion terminating in a rounded end, said tube also provided with a plurality of openings communicating with said opening of said base through said hollow body of said tube, an elastic and expandable finger-like covering having an opening and fitting snugly over said body and rounded end of said tube, the periphery of said opening of said latter cover secured circumferentially to said base, the circumference of said covering ranging from 8 mm to 40 mm, a reservoir containing sterilized fluid having an end provided with an opening and engagement means, said reservoir separably secured to said base by the engagement of both of the aforesaid engagement means, said reservoir also in fluid communication with said tube, means for applying pressure to said reservoir causing said fluid to flow through said opening of said Reservoir into said hollow elongated tube and out through said orifices of said tube into said expandable covering expanding the same and said urethra.
Claim 3
Dependent Claim 15 words
