Abstract
Abstract A pacemaker terminal for connecting an electrode lead having a proximal end includes a first section fixed to the pacemaker and a second section moveably engaged with the first section. A spring element is interposed between the first and second sections to exert a force to displace the moveable section from the fixed section. Both sections have transverse holes which, upon application of squeezing pressure to the terminal to overcome the spring action, become aligned so as to allow insertion of the proximal end of the electrode lead. Thereafter, upon release of the pressure, the spring element displaces the sections so as to capture the electrode lead securely in the holes. The holes may be provided with an internal thread, such as an asymmetrial sawtooth pattern, to aid in holding the lead in place and maintaining electrical contact with it.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
114 words
A pacemaker terminal for connecting an electrode lead having a proximal end to a pacemaker, comprising: a first section having a first transverse hole; a second section having a second transverse hole, said second section being moveably engageable with said first section for aligning said first transverse hole with said second transverse hole to receive the proximal end of the electrode lead; and means for springingly displacing said second section from said first section so as to move said first and said second transverse holes out of alignment and securely capture the proximal end of the electrode lead therein, said displacing means comprising a canted metallic spring interposed between said first and second sections.
Claim 2
Dependent Claim
114 words
A pacemaker terminal for connecting an electrode lead having a proximal end to a pacemaker, comprising: a first section having a first transverse hole; a second section having a second transverse hole, said second section being moveably engageable with said first section for aligning said first transverse hole with said second transverse hole to receive the proximal end of the electrode lead; and means for springingly displacing said second section from said first section so as to move said first and said second transverse holes out of alignment and securely capture the proximal end of the electrode lead therein, said displacing means comprising a canted metallic spring interposed between said first and second sections.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
14 words
A pacemaker terminal as recited in claim 2, wherein said internal thread is symmetrical.
Claim 5
Dependent Claim
14 words
A pacemaker terminal as recited in claim 2, wherein said internal thread is asymmetrical.
Claim 6
Dependent Claim
17 words
A pacemaker terminal as recited in claim 1, wherein said second transverse hole includes an internal thread.

Claim 9
Dependent Claim
149 words
A pacemaker terminal for connecting an electrode lead having a proximal end to a pacemaker, comprising: a first section having a neck portion with a first hole transversely therethrough; a second section having a pair of side portions with a second hole transversely therethrough and an intermediate portion joining said side portions, said second section being moveably disposed on said first section with said side portions engaging said neck portion for aligning said first hole with said second hole to receive the proximal end of the electrode lead therein; and means for sparingly displacing said second section from said first section so as to move said first and second holes out of alignment and securely capture the proximal end of the electrode lead therein, said displacing means comprising a canted metallic spring interposed between said intermediate portion of said second section and said neck portion of said first section.
Claim 10
Dependent Claim
149 words
A pacemaker terminal for connecting an electrode lead having a proximal end to a pacemaker, comprising: a first section having a neck portion with a first hole transversely therethrough; a second section having a pair of side portions with a second hole transversely therethrough and an intermediate portion joining said side portions, said second section being moveably disposed on said first section with said side portions engaging said neck portion for aligning said first hole with said second hole to receive the proximal end of the electrode lead therein; and means for sparingly displacing said second section from said first section so as to move said first and second holes out of alignment and securely capture the proximal end of the electrode lead therein, said displacing means comprising a canted metallic spring interposed between said intermediate portion of said second section and said neck portion of said first section.
Claim 11
Dependent Claim
