Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
84 words
A catheter type instrument comprising a bobbin, made in 2 halves, of medically-approved plastic, connected by a light tension spring, through which pass an inner and outer cable, made of metal or plastic, both operating two umbrella type op -ening and closing mechanisms, one each side of the bobbin, which operate a plurality of fingers; the operation of the inner and outer cables being by two draw-shoulders, tensioned by a spring, and lockable in any position by a multi-slotted locking plate and a pin.

A catheter type instrument comprising a bobbin, made in 2 halves, of medically-approved plastic, connected by a light tension spring, through which pass an inner and outer cable, made of metal or plastic, both operating two umbrella type op -ening and closing mechanisms, one each side of the bobbin, which operate a plurality of fingers; the operation of the inner and outer cables being by two draw-shoulders, tensioned by a spring, and lockable in any position by a multi-slotted locking plate and a pin.
Claim 3
Dependent Claim
30 words
A catheter type instrument according to Claim 1 in which the spring attached to the two bobbin halves is replaced by a small permanent magnet inserted in each bobbin half.
Claim 4
Dependent Claim
38 words
A catheter type instrument according to Claim 1 or Claim 2 in which each bobbin half has a shallow recess formed around the circumference near to the nose of each bobbin half, into which the fingers will position.
Claim 5
Dependent Claim
30 words
