Implantation of a medical device within a lumen
First Claim
1. A system for implantation of a medical device within a lumen of a patient comprising:
- the medical device, wherein the medical device comprises;
a device housing sized for introduction into the lumen, electrical circuitry mounted within the device housing, a tether member that includes a proximal end that is coupled to the device housing, and an anchor member located at a distal portion of the tether member;
an elongated delivery device with a distal portion that defines a cavity;
a vacuum port to draw tissue of a wall of the lumen into the cavity;
a needle that defines a bore, wherein the bore receives the anchor member of the medical device, and the needle is advancable into the cavity and through the tissue disposed in the cavity while the anchor member is received by the bore to form a passageway from the lumen, through the tissue, and back into the lumen; and
an ejection tool that is advancable through the bore of the needle to eject the anchor member from the bore when the needle has been advanced though the tissue.

Abstract
A medical device implanted within a lumen of a patient, such as the esophagus, stomach, or another portion of the gastrointestinal tract, includes a device housing and a lead that extends from the device housing. An anchor member is located at a distal portion of the lead, and the lead includes one or more electrodes located between the device housing and the anchor member. A delivery system for implanting the medical device within the lumen includes an elongated delivery device and a needle. The needle includes a bore to receive the anchor member of the medical device. The delivery system inserts the anchor member through a passageway from the lumen, through the tissue, and back into the lumen.

23. A method for implanting a medical device within a lumen of a patient comprising:
-
inserting an anchor member of the medical device into a bore of a needle;
advancing the needle through tissue of the lumen with the anchor member inserted in the bore to create a passageway from the lumen, through the tissue, and back into the lumen, and place a tether member of the medical device coupled to the anchor member within the passageway; and
ejecting the anchor member from the bore to place the anchor member on a first side of the passageway while a device housing of the medical device coupled to the tether member is located on a second side of the passageway, wherein the anchor member and the device housing keep the tether member within the passageway. - View Dependent Claims (24, 25)
