## Abstract

The present application provides a delivery device (10) for percutaneously implanting a medical implant (1) in tissue of a patient. The delivery device comprises a delivery sheath (12, 13, 53, 61, 62, 65, 66) adapted to at least partially surround the medical implant and carry the medical implant for percutaneous delivery in the patient's tissue. The delivery device also includes a power delivery system (37) adapted to provide electric power to the medical implant within the delivery sheath.

The delivery device of claim 3, wherein the wireless power transmitter is disposed in the delivery sheath.

### Claim 5 (depends on 3)

The delivery device of claim 3, further comprises a guide adapted to constrain a position and orientation of the delivery sheath relative to the patient during use, and wherein the power delivery system is provided in the guide.

### Claim 6 (depends on 1)

The delivery device of claim 1, further comprising a power source, for example a battery, or a connector for an external power source, such as mains power, or an external battery, or a wireless power receiver for coupling with an external wireless power transmitter.

### Claim 7 (depends on 1)

The delivery device of claim 1, wherein the delivery device comprises a handle and the delivery sheath extends from the handle.

### Claim 8 (depends on 7)

The delivery device of claim 7, wherein at least a part of the delivery sheath is retractable relative to the handle to partially expose the medical implant during percutaneous delivery in the patient's tissue.

### Claim 9 (depends on 8)

The delivery device of claim 8, wherein at least a part of the delivery sheath is retractable to release the medical implant in the patient's tissue.

### Claim 10 (depends on 7)

The delivery device of claim 7, wherein the delivery sheath comprises a needle, or a cannula.

### Claim 11 (depends on 1)

The delivery device of claim 1, wherein the medical implant comprises a housing portion and an elongate electrode lead extending from the housing portion, and wherein the delivery sheath is adapted to carry the housing portion for percutaneous delivery in the patient's tissue.

### Claim 12 (depends on 11)

The delivery device of claim 11, wherein the delivery sheath is adapted to also carry the elongate electrode lead for percutaneous delivery in the patient's tissue.

### Claim 13 (depends on 12)

The delivery device of claim 12, wherein the delivery sheath comprises a retractable portion adapted to carry the elongate electrode lead for percutaneous delivery in the patient's tissue.

### Claim 14 (depends on 1)

The delivery device of claim 1, wherein the medical implant is a neurostimulator implant, and wherein the delivery device further comprises a sensor operable to detect a reaction of the patient when the power delivery system provides electric power to the neurostimulator implant during percutaneous delivery.

### Claim 15 (depends on 14)

The delivery device of claim 14, wherein the sensor is configured to detect a movement reaction of the patient.

### Claim 16 (depends on 14)
