Abstract

A device, system and method for diagnosing and treating a patient is provided where a functional device is attached to a stomach wall. The device in one embodiment provides electrical stimulation of the stomach wall. The device may also have other functional aspects such as a sensor for sensing various parameters of the stomach or stomach environment, or a substance delivery device. The implant may be programmed to respond to sensed information or signals. The device may be modular with a portion of the device accessible for removal and replacement. In one embodiment, an endoscopic delivery system delivers the functional device through the esophagus and into the stomach where it is attached the stomach wall with the assistance of a suction used to stabilize the tissue of the stomach wall. The device includes a chamber for receiving tissue of the stomach wall for attachment where a vacuum pressure is applied through the chamber to draw the tissue into the chamber.

Claims

1. An endoscopic instrument system comprising:

an instrument including;

an elongate member comprising a distal portion for extending distally of an endoscope, the distal portion of the elongate member having a first profile; and

a radially expanding member configured to expand at least a portion of the distal portion of the elongate member in a radial direction to create a second profile larger than the first profile; and

an implantable gastrointestinal diagnostic or treatment device releasably engageable by the instrument, the implantable device having circuitry and a connector, the circuitry having an input for sensor signals indicative of a condition of a stomach and an output for transmitting diagnostic or stimulation signals in response to the sensor signals, the connector having an opening larger than the distal portion in the first profile so that the implantable device can be released from the instrument within a patient, the opening being sized to engage the distal portion in the second profile so that the implantable device is carried by the instrument.

3. The endoscopic instrument system of claim 1, further comprising a balloon coupled to the distal portion of the elongate member,

wherein the elongate member comprises a lumen in fluid communication with the balloon to provide an inflation medium to the balloon, and

wherein the balloon is configured to radially expand upon introduction of an inflation medium into the balloon to create a second, larger profile to engage the connector of the implantable device.

2. An endoscopic instrument system comprising:

an instrument including;

an elongate member comprising a distal portion for extending distally of an endoscope, the distal portion of the elongate member having a first profile;

a radially expanding member configured to expand at least a portion of the distal portion of the elongate member in a radial direction to create a second profile larger than the first profile; and

a wire member; and

an implantable gastrointestinal diagnostic or treatment device releasably engageable by the instrument, the implantable device having a connector with an opening larger than the distal portion in the first profile so that the implantable device can be released from the instrument within a patient, the opening being sized to engage the distal portion in the second profile so that the implantable device is carried by the instrument;

wherein the elongate member comprises a lumen configured to receive the wire member, wherein the distal portion comprises a side opening in communication with the lumen, and wherein the side opening is configured to permit a portion of the wire member to extend from the lumen through the side opening to create the second larger profile to engage the connector of the implantable device.
