Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
68 words
A surgical knot manipulator device comprising: an elongated, cylindrical body member having a proximal end and a distal end wherein a smooth surface incline is formed with a reduced diameter continuously within a surface of the cylindrical body member near its distal end; a handle located at the proximal end of the body member; and a circular ring member located at the distal end of the body member.
Claim 2
Dependent Claim
68 words
A surgical knot manipulator device comprising: an elongated, cylindrical body member having a proximal end and a distal end wherein a smooth surface incline is formed with a reduced diameter continuously within a surface of the cylindrical body member near its distal end; a handle located at the proximal end of the body member; and a circular ring member located at the distal end of the body member.
