Abstract
Abstract A latch for securing the ends of a belt together so as to encircle an inflatable cuff of an artificial sphincter. The latch includes two rotatable components with cavities which receive the belt ends when the components are suitably rotated and capture the belt ends within the latch when the belt is in tension.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
109 words
A latch for securing the ends of a belt together so as to encircle an inflatable cuff of an artificial sphincter, said latch comprising: two components mounted on a common pin, at least one of said components being at least partly rotatable about said pin relative to said other component, each of said components including at least one cavity for receipt of a portion of the belt end, said cavities being accessible for insertion or removal of said belt portion upon suitable rotation of at least one of said components, said inserted belt ends being captured within said cavities when said two components are in a rotatably stabilized condition.
Claim 2
Dependent Claim
109 words
A latch for securing the ends of a belt together so as to encircle an inflatable cuff of an artificial sphincter, said latch comprising: two components mounted on a common pin, at least one of said components being at least partly rotatable about said pin relative to said other component, each of said components including at least one cavity for receipt of a portion of the belt end, said cavities being accessible for insertion or removal of said belt portion upon suitable rotation of at least one of said components, said inserted belt ends being captured within said cavities when said two components are in a rotatably stabilized condition.
Claim 3
Dependent Claim
39 words
The latch of claim 1 wherein said components are in a rotatably stabilized condition when said belt ends are inserted in said latch and said belt is in tension upon inflation of said inflatable cuff by an inflating means.
Claim 4
Dependent Claim
60 words
The latch of claim 1 wherein at least one of the belt ends is bifurcated into two fingers, each terminating in an enlarged bead, each cavity being predeterminedly dimensioned for snugly accommodating a bead therein, each component having a slit communicating with each of said cavities permitting the fingers to extend therethrough when said beads are inserted into said cavities.
Claim 5
Dependent Claim
68 words
The latch of claim 3 wherein each component has an opposing surface, said surfaces being offset to permit rotation of at least one of said components, each of said cavities having a port in an opposing surface, said offset being dimensioned so as to prevent insertion or removal of said beads through said ports and between said opposing surfaces when said components are in a rotatably stabilized position.
Claim 6
Dependent Claim
31 words
The latch of claim 4 wherein the belt is bifurcated at each end, each of said components having two cavities, and each component accommodating a bead from each opposing belt end.
Claim 7
Dependent Claim
43 words
The latch of claim 5 wherein said of two components are block-like in shape, each component having two side surfaces parallel to said pin and an inner and outer surface perpendicular to said pin, said inner surface of each component opposing each other.
Claim 8
Dependent Claim
43 words
The latch of claim 6 wherein said cavities are parallel to said pin, each cavity having a port in said inner surface of said corresponding component, each of said slits extending through a side surface of each component and interconnecting with said cavity.
Claim 9
Dependent Claim
10 words
The latch of claim 7 wherein said components are identical.
