## Abstract

A compressible electrode for the stimulation of the musculature of the pelvic floor complex e.g. for the treatment of anterior and posterior pelvic floor muscle dysfunction, is reversibly compressible and has electro-conductive elements. The compressible electrode may be used with all the usual control units and treatment regimes for the electro-stimulation of the musculature and nerves of the vagina and/or anus. The compressible electrode may be inserted into the vagina or anus through the use of an applicator. In the compressed state the compressible electrode may be of tampon proportions and after use may easily be removed.

## Claims

### Claim 1

A compressible vaginal or anal electro-stimulation electrode for the neuromuscular electro-stimulation of the musculature of the pelvic floor complex, which comprises a deformable electrode body of resiliently compressible foam material and at least two separate electro-conductive elements located at or on the external surface of the deformable electrode body and wherein the deformable electrode body dimensions are reducible upon compression by at least 15%.

### Claim 2 (depends on 1)

An electrode as claimed in claim 1, wherein the whole electrode is insertable into the interior of the vaginal or anal cavity.

### Claim 3 (depends on 1)

An electrode as claimed in claim 1, wherein the electrode is conformable to that vaginal or anal cavity during use.

### Claim 4 (depends on 1)

An electrode as claimed in claim 1, wherein the electro-conductive elements conform with the deformation of the device body.

### Claim 5 (depends on 1)

An electrode as claimed in claim 1, wherein at least one of the electro-conductive elements is non-annular.

### Claim 6 (depends on 1)

An electrode as claimed in claim 1, wherein the interior of the electrode foam body is hollow.

### Claim 7 (depends on 1)

An electrode as claimed in claim 1, wherein the volume of the electrode in the compressed state is reduced by at least 20% compared to that in the non-compressed state.

### Claim 8 (depends on 1)

An electrode as claimed in claim 1, wherein the electrode is compressible to relative dimensions that are different in proportion to the dimensions of the electrode in the non-compressed state.

### Claim 9 (depends on 1)

An electrode as claimed in claim 1, wherein the foam density is less than 250 Kgm−3.

### Claim 10 (depends on 1)

An electrode as claimed in claim 1, wherein the foam is an open celled foam.

### Claim 11 (depends on 1)

An electrode as claimed in claim 1, wherein the electrode body exhibits different degrees of compressibility at two or more axis perpendicular to the axis of insertion of the electrode.
