Abstract
Abstract A cervical cuff for holding closed an incontinent cervix, comprising a stiffly flexible substantially inelastic support ring having a central axis and an inner and an outer peripheral wall. The inner wall forms an opening to receive the neck of the cervix. A first and second elastic impermeable membrane extends around and is mounted to the inner and outer walls respectively so as to form a first and second laterally expansible chamber. Inflation of the chambers extends the membranes so that the inner membrane engages the cervical neck inside the opening, and the outer membrane engages body tissue surrounding and spaced from the cervical neck. The ring is thereby retained in the body and the neck is held closed inside the ring.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
A cervical cuff for holding closed the neck of an incontinent cervix comprising: a stiffly flexible, substantially inelastic support ring having a central axis and an inner and an outer peripheral wall, the inner wall forming an opening to receive the neck of the cervix; a first and a second elastic fluid-tight membrane extending around and mounted to the said inner and outer wall respectively, forming a first and a second laterally expansible chamber, means permitting the inflation of said first and second chambers whereby inflation of said chambers extends said membranes laterally so that the inner membrane engages a cervical neck inside the opening, and the outer membrane engages body tissues surrounding and spaced from the cervical neck, whereby to retain the ring in the body while the inner membrane holds closed the cervical neck.
Claim 2
Dependent Claim
136 words
A cervical cuff for holding closed the neck of an incontinent cervix comprising: a stiffly flexible, substantially inelastic support ring having a central axis and an inner and an outer peripheral wall, the inner wall forming an opening to receive the neck of the cervix; a first and a second elastic fluid-tight membrane extending around and mounted to the said inner and outer wall respectively, forming a first and a second laterally expansible chamber, means permitting the inflation of said first and second chambers whereby inflation of said chambers extends said membranes laterally so that the inner membrane engages a cervical neck inside the opening, and the outer membrane engages body tissues surrounding and spaced from the cervical neck, whereby to retain the ring in the body while the inner membrane holds closed the cervical neck.
