Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
A medical instrument to insert a bead chain into a patient''s bladder comprising: a first elongated member having an operating end and an operational end; a second elongated member having an operational end and an operational end; connecting means to pivotally connect together said first and said second members intermediate said ends; each of said operating ends including first means for facilitating manual pivoting of said members about a pivot axis with respect to each other; and each of said operational ends includes second means for facilitating the retention of a bead chain, said second means comprises a longitudinal recess formed within both said members, such both said recesses extending substantially the entire length of its respective operational end, each said recess being a uniform depth and width along said entire length of its respective operational end, each of said operational ends being curved so as to result in a smooth contour to facilitate locating of said medical instrument within the urethra, said pivot axis lying within the plane of said curve.
Claim 2
Dependent Claim
172 words
A medical instrument to insert a bead chain into a patient''s bladder comprising: a first elongated member having an operating end and an operational end; a second elongated member having an operational end and an operational end; connecting means to pivotally connect together said first and said second members intermediate said ends; each of said operating ends including first means for facilitating manual pivoting of said members about a pivot axis with respect to each other; and each of said operational ends includes second means for facilitating the retention of a bead chain, said second means comprises a longitudinal recess formed within both said members, such both said recesses extending substantially the entire length of its respective operational end, each said recess being a uniform depth and width along said entire length of its respective operational end, each of said operational ends being curved so as to result in a smooth contour to facilitate locating of said medical instrument within the urethra, said pivot axis lying within the plane of said curve.
Claim 3
Dependent Claim
53 words
A medical instrument as defined in claim 1 wherein: said operational ends capable of assuming a substantially aligned abutting relationship with respect to each other with there being a surface upon one of said operational ends capable of coming into substantial abutting contact with a surface upon the other of said operational ends.
Claim 4
Dependent Claim
27 words
A medical instrument as defined in claim 1 including: a latching means connected to said members, said latching means to retain said members in a closed position.
Claim 5
Dependent Claim
17 words
The medical instrument as defined in claim 3 wherein: said latching means located on said operating ends.
Claim 6
Dependent Claim
104 words
In combination with a bead chain, said bead chain to be inserted into a patient''s bladder to perform a cystourethrogram, a medical instrument to insert said bead chain comprising: a first elongated member having an operating end and an operational end; a second elongated member having an operating end and an operational end; connecting means to pivotally connect together said first and seconD members intermediate said end; each of said operating ends including first means for facilitating manual pivoting of said members with respect of each other; and each of said operational ends includes second means for facilitating the retention of said bead chain.
Claim 7
Dependent Claim
104 words
In combination with a bead chain, said bead chain to be inserted into a patient''s bladder to perform a cystourethrogram, a medical instrument to insert said bead chain comprising: a first elongated member having an operating end and an operational end; a second elongated member having an operating end and an operational end; connecting means to pivotally connect together said first and seconD members intermediate said end; each of said operating ends including first means for facilitating manual pivoting of said members with respect of each other; and each of said operational ends includes second means for facilitating the retention of said bead chain.
Claim 8
Dependent Claim
69 words
The combination of claim 5 wherein: said operational ends capable of assuming a substantially aligned abutting relationship with respect to each other with there being a surface upon one of said operational ends capable of coming into substantial abutting contact with a surface upon the other of said operational ends, said second means includes forming of an elongated recess along one of said surfaces of a said operational end.
Claim 9
Dependent Claim
46 words
The combination as defined in claim 6 wherein: both of said surfaces of said operational ends are formed into an elongated recess, whereby the bead chain is readily adapted to be temporarily retained within each of said elongated recesses with said members in a closed position.
Claim 10
Dependent Claim
26 words
The combination as defined in claim 6 wherein: each of said operational ends is curved whereby to facilitate locating of said medical instrument within the urethra.
Claim 11
Dependent Claim
