Abstract
An implantable device includes a conduit, an adjustable membrane element coupled to the conduit near the front end of the conduit for controllable coaptation of a body lumen, such as coaptation of a urethra as treatment for urinary incontinence, and a fixation mechanism at or near the front end of the conduit. In various embodiments, the fixation mechanism can anchor the implantable device to the tissue using a movement of a push wire. Optionally, the fixation mechanism can also allow the implantable device to be released from the tissue using another movement of the push wire, to allow for repositioning or removal of the implantable device.
Claims20
A method for coapting a body lumen in tissue of a living body, the method comprising:
- implanting an implantable device into the tissue, the implantable device including:
- an adjustable membrane element including a continuous wall having an inner surface defining a chamber;
- an elongate conduit including a conduit peripheral surface, a conduit rear end, a conduit front end, and a push wire lumen, the conduit peripheral surface connected to and sealed to the adjustable membrane element at or near the conduit front end, the push wire lumen extending longitudinally in the conduit and having an inlet to receive a portion of a push wire and a diameter suitable for accommodating the received portion of the push wire;
- and
- a fixation mechanism configured to anchor the implantable device to the tissue, the implantation including using the push wire to position the adjustable membrane element at a target site;
- partially inflating the adjustable membrane element to allow for tissue encapsulation to stabilize the adjustable membrane element in the tissue at the target site;
- activating the fixation mechanism to anchor the implantable device to the tissue using push wire movement including longitudinal movement of the push wire while the adjustable membrane element is partially inflated for a period of time;
- and
- adjusting a volume of the adjustable membrane element after the period of time to coapt the body lumen.
A method for coapting a body lumen in tissue of a living body, the method comprising:
- implanting an implantable device into the tissue, the implantable device including:
- an adjustable membrane element including a continuous wall having an inner surface defining a chamber;
- an elongate conduit including a conduit peripheral surface, a conduit rear end, a conduit front end, and a push wire lumen, the conduit peripheral surface connected to and sealed to the adjustable membrane element at or near the conduit front end, the push wire lumen extending longitudinally in the conduit and having an inlet to receive a portion of a push wire and a diameter suitable for accommodating the received portion of the push wire;
- and
- a fixation mechanism configured to anchor the implantable device to the tissue, the implantation including using the push wire to position the adjustable membrane element at a target site;
- partially inflating the adjustable membrane element to allow for tissue encapsulation to stabilize the adjustable membrane element in the tissue at the target site;
- activating the fixation mechanism using a rotational movement of the push wire in a tightening rotational direction to anchor the implantable device to the tissue while the adjustable membrane element is partially inflated for a period of time;
- and
- adjusting a volume of the adjustable membrane element after the period of time to coapt the body lumen,
- wherein implanting the implantable device into the tissue includes advancing the implantable device in the tissue using longitudinal movement of the push wire.
An implantable device configured to be positioned in tissue of a living body using a push wire for coaptation of a body lumen of the living body, the implantable device comprising:
- an adjustable membrane element including a continuous wall having an inner surface defining a chamber;
- an elongate conduit including a conduit peripheral surface, a conduit rear end, a conduit front end, and a push wire lumen, the conduit peripheral surface connected to and sealed to the adjustable membrane element at or near the conduit front end, the push wire lumen extending longitudinally in the conduit and having an inlet to receive a portion of the push wire, a diameter suitable for accommodating the received portion of the push wire, and a lumen front end at the conduit front end, the lumen front end configured to allow the implantable device to be advanced in the tissue using longitudinal movement of the push wire;
- and
- a fixation mechanism coupled to the conduit front end and configured to anchor the implantable device to the tissue by being activated using another movement of the push wire while the implantable device is placed in the tissue with the adjustable membrane element positioned at a target site and partially inflated to allow for tissue encapsulation to stabilize the adjustable membrane element in the tissue at the target site,
- wherein the implantable device is configured for implantation within the tissue with the adjustable membrane element adjacent the body lumen to provide for adjustable coaptation to the body lumen.
