Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
58 words
A medical electrode for implantation in a body, comprising a hollow conductor, 2 forcep-like hooks at the tip of the electrode, having legs connected together, said hooks opening by resilience of said legs, a compression coil spring around said legs, forcing said legs into itself, thus closing said hooks and a guide stylet for remotely opening said hooks.
Claim 2
Dependent Claim
58 words
A medical electrode for implantation in a body, comprising a hollow conductor, 2 forcep-like hooks at the tip of the electrode, having legs connected together, said hooks opening by resilience of said legs, a compression coil spring around said legs, forcing said legs into itself, thus closing said hooks and a guide stylet for remotely opening said hooks.
Claim 3
Dependent Claim
25 words
The invention as defined in claim 1, said guide stylet being centered by the end of said compression coil spring, said end being stop wound.
Claim 4
Dependent Claim
43 words
A medical electrode for implantation in a body, comprising a non-hollow conductor, 2 forcep-like hooks having legs connected together, said hooks opening by resilience of said legs, a compression coil spring closing said hooks and a guide catheter for remotely opening said hooks.
Claim 5
Dependent Claim
43 words
A medical electrode for implantation in a body, comprising a non-hollow conductor, 2 forcep-like hooks having legs connected together, said hooks opening by resilience of said legs, a compression coil spring closing said hooks and a guide catheter for remotely opening said hooks.
