Abstract
A delivery device (10) for percutaneously implanting a medical implant (1) in tissue of a patient includes 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.
Claims43
A delivery device for percutaneously implanting a medical implant in tissue of a patient, the delivery device comprising:
- a delivery sheath adapted to at least partially surround the medical implant and carry the medical implant for percutaneous delivery in the patient's tissue, and
- a power delivery system adapted to provide electric power to the medical implant within the delivery sheath.
A medical implant for implantation in tissue of a patient, the medical implant comprising:
- a wireless power receiver, and
- power terminals for forming an electrical connection with electrical connectors of a delivery device during implantation of the medical implant.
A medical implant for implantation in tissue of a patient, the neurostimulator implant comprising:
- a first wireless power receiver for wireless power coupling with an external wireless power transmitter when implanted in the patient, and
- a second wireless power receiver for wireless power coupling with a wireless power transmitter of a delivery device during implantation of the medical implant.
A method of percutaneously implanting a medical implant in tissue of a patient, the method comprising:
- providing a delivery device having a power delivery system and a delivery sheath carrying the medical implant,
- percutaneously positioning the delivery sheath in the patient's tissue, and
- testing the position of the medical implant by powering the medical implant within the delivery sheath by the power delivery system of the delivery device.
A delivery device for percutaneously implanting a medical implant in tissue of a patient, the delivery device comprising:
- a delivery sheath adapted to at least partially surround the medical implant and carry the medical implant for percutaneous delivery in the patient's tissue, and
- an impedance sensor comprising a first electrode on the delivery sheath and a second electrode arranged to contact the patient at a location spaced from the first electrode,
- wherein the impedance sensor is operable to detect an electrical impedance between the first electrode and the second electrode to detect a change in the tissue at the delivery sheath during percutaneous delivery of the medical implant.
A method of percutaneously implanting a medical implant in tissue of a patient, the method comprising:
- percutaneously positioning a delivery sheath of a delivery device, the delivery sheath carrying the medical implant,
- detecting an electrical impedance between a first electrode on the delivery sheath and a second electrode in contact with the patient at a location spaced from the first electrode, and analysing the detected electrical impedance to detect a change in the tissue at the delivery sheath during percutaneous delivery of the medical implant.
A method of percutaneously delivering a neurostimulator implant into tissue of a patient, the method comprising:
- percutaneously positioning a delivery sheath carrying the neurostimulator implant;
- detecting a change in electrical impedance between a first electrode on the delivery sheath and a second electrode in contact with the patient at a location spaced from the first electrode, the change in electrical impedance being indicative of a change in the patient's tissue at the delivery sheath;
- and
- powering the neurostimulator implant within the delivery sheath to test a position of the neurostimulator implant relative to a nerve of the patient.
