## Abstract

The set comprises a totally implantable device (1) for electroneuromodulation for the electric stimulation of the nervous tissue of the wall of the stomach and/or another neuroreceptive biological tissue and an implantation tool (2) of the device (1), the tool (2) comprising an axially hollow longitudinal containment body (6) for said device (1) and a needle (12) incorporated into said containment body (6) and having a tip (13) that projects forwards to a sharp front end (7) of the containment body (6), said needle (12) being connected to a supply conduit (15) of a fluid injectable from said needle (12) into the tissue for the creation of a localized tissue swelling (4) in which said device (1) can be positioned.

## Claims

### Claim 1

A set comprising:
a totally implantable device for electroneuromodulation for the electric stimulation of a neuroreceptive biological tissue; and
an implantation tool of the device, comprising:
an axially hollow longitudinal containment body for the device; and
a needle incorporated into the containment body and having a tip that projects forward to a sharp front end of the containment body, the needle being connected to a supply conduit of a fluid injectable from the needle into the neuroreceptive biological tissue for the creation of a localized tissue swelling in which the device can be positioned;
where the containment body has a base at a rear thereof from which a rigid tubular connection develops and communicates with an inside of the containment body through a through opening of the base of the containment body, the supply conduit extending into the rigid tubular connection through the through opening of the base of the containment body.

### Claim 2 (depends on 1)

The set of claim 1, wherein the device further comprises independent electrical energy production means necessary for the generation of electric pulses for stimulation or for other functions.

### Claim 3 (depends on 2)

The set of claim 2, wherein the independent electrical energy production means comprises at least one piezoelectric longitudinal element external to the device for recovery of electrical energy from natural movement of the tissue inside which the device is implanted.

### Claim 4 (depends on 1)

The set of claim 1, wherein the needle develops along an axial generatrix of the containment body which passes through a most advanced point of the sharp front end of the containment body.

### Claim 5 (depends on 1)

The set of claim 1, wherein the containment body has an internal circular cross section and an external circular cross section, the internal circular cross section being non-concentric with the external circular cross section to define a thickening of the containment body, where the needle develops at the thickening of the containment body.

### Claim 6 (depends on 1)

The set of claim 1, further comprising:
a piston for ejecting the device slidably in the containment body; and
a flexible activation cable which extends into the rigid tubular connection through the through opening of the rear of the base of the containment body.

### Claim 7 (depends on 6)

The set of claim 6, having a configuration wherein, when the piston is fully retracted within the containment body, with the device resting against the piston, a front end of the device is at least partially outside the sharp front end of the containment body.
