Abstract
Abstract A stimulator device for insertion in a living body and having particular advantage for intra-cardiac use comprising a structure having a body form of a size and configuration to enable its transvenous or transarterial insertion, the surface of said body form providing electrode means for contact with a portion of the living body to be stimulated by said electrode means, and means mounted to project outwardly of and peripherally of said body form including anchor portions locating in a position displaced from said electrode means and providing means for engaging in portions of said living body to establish said electrode means in a required position of use, said electrode means having in connection therewith means to energize the same once said body form is located in its required position of use.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A stimulator device for insertion in a living body and having particular advantage for intracardiac use comprising a structure having a body form for transvenous or transarterial insertion, electrode means on the surface of said body form for contact with a portion of the living body to be stimulated by said electrode means, and means mounted to project outwardly of and peripherally of said body form including anchor portions locating in a position displaced from said electrode means and providing means for engaging in portions of said living body to establish said electrode means in a required position of use, said electrode means having in connection therewith means to energize the same once said body form is located in its required position of use.
Claim 2
Dependent Claim
124 words
A stimulator device for insertion in a living body and having particular advantage for intracardiac use comprising a structure having a body form for transvenous or transarterial insertion, electrode means on the surface of said body form for contact with a portion of the living body to be stimulated by said electrode means, and means mounted to project outwardly of and peripherally of said body form including anchor portions locating in a position displaced from said electrode means and providing means for engaging in portions of said living body to establish said electrode means in a required position of use, said electrode means having in connection therewith means to energize the same once said body form is located in its required position of use.
Claim 3
Dependent Claim
28 words
A stimulator device as in claim 1 wherein said means to energize said electrode means includes a power source positioning in a location remote from said body form.
Claim 4
Dependent Claim
24 words
A stimulator device as in claim 1 wherein said means to energize said electrode means includes a power source embodied within said body form.
Claim 5
Dependent Claim
19 words
A stimulator device as in claim 1 wherein spaced surface portions of said body form define separate electrode means.
Claim 6
Dependent Claim
48 words
A structure as in claim 1 wherein said anchor portions are defined by wire like segments connected with and biased to normally project outwardly from said body form to facilitate the establishment of a connection thereof with said living body in an area displaced from said electrode means.
Claim 7
Dependent Claim
37 words
A stimulator device as in claim 1 wherein said electrode means have a fixed positioning in respect to said body form and comprise at least two electrodes, and said body form includes insulator means separating said electrodes.
Claim 8
Dependent Claim
27 words
A stimulator device as in claim 1 characterized by said body form being a unitized structure having means for guiding the same for transvenous or transarterial insertion.
