Abstract

ABSTRACT A medical device for actively stretching a stomach Wall of a patient for creating a sensation of satiety. The medical device being implantable and comprising a first member configured to be fixated to a first portion of the stomach Wall, a second member configured to be fixated to a second portion of the stomach Wall, an operation device for operating the second member to displace the second member in a f1rst direction relative to the f1rst member, for stretching the stomach Wall between the first and second portion.

Claims (17)

Claims
1. A medical device for actively stretching Wall portion of a stomach or intestine of a human for creating a sensation of satiety, the medical device being implantable and comprising: an operable first member configured to be fixated to a first portion of the Wall of the stomach or intestine, a piezoelectric operation device configured to at least one of: move at least a portion of the first member in a first direction, and alter the first member, such that the Wall of the stomach or intestine is actively stretched for creating a sensation of satiety.
2. The medical device according to claim 1, Wherein the piezoelectric operation device comprises a piezoelectric motor.
