Claim 1
Independent Claim
65 words
A prosthesis for controlling urinary incontinence comprising support means including a portion in the form of at least one turn of a spiral, said portion including a wall of generally non-stretchable construction and arranged for disposition about the corpus spongiosum and urethra, plural inflatable chambers located at spaced locations along said portion and means for inflating said chambers with a fluid to constrict said urethra.
Claim 2
Dependent Claim
65 words
A prosthesis for controlling urinary incontinence comprising support means including a portion in the form of at least one turn of a spiral, said portion including a wall of generally non-stretchable construction and arranged for disposition about the corpus spongiosum and urethra, plural inflatable chambers located at spaced locations along said portion and means for inflating said chambers with a fluid to constrict said urethra.
