Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
88 words
An implantable body tissue stimulator adapted to be anchored and stored in a selected body cavity, comprising: a housing; means within said housing for generating electrical tissue stimulating signals; and porous means substantially totally enclosing said housing for securing it to living tissue and adapted to anchor it in place in said selected cavity by enabling body processes to interact with said enclosing means, said means including flap means enabling later removal and replacement of said housing without interfering with the anchoring in place of said enclosing means.
Claim 2
Dependent Claim
88 words
An implantable body tissue stimulator adapted to be anchored and stored in a selected body cavity, comprising: a housing; means within said housing for generating electrical tissue stimulating signals; and porous means substantially totally enclosing said housing for securing it to living tissue and adapted to anchor it in place in said selected cavity by enabling body processes to interact with said enclosing means, said means including flap means enabling later removal and replacement of said housing without interfering with the anchoring in place of said enclosing means.
Claim 3
Dependent Claim
12 words
The stimulator of claim 1 wherein: said stimulator is a cardiac pacer.
Claim 4
Dependent Claim
42 words
The pacer of claim 2, wherein: said housing is conductive and effectively provides a terminal for an electric circuit; and said enclosing means is formed from a mesh and includes a gauze suture panel for securing said enclosed pacer to living tissue.
Claim 5
Dependent Claim
47 words
The pacer of claim 3, wherein: said enclosing means includes a set of flaps sewn together to form a bag for receiving and retaining said housing; and said suture panel includes a pair of flaps sewn to opposite sides of said bag for suturing to living tissue.
