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 first direction relative to the first member, for stretching the stomach wall between the first and second portion.
Claims31
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, comprising:
- a first member rotating section, configured to rotate around a first axis,
- and a first member fixation section coupled to the first member rotating section and configured to be fixated to a first portion of the stomach wall;
- a second member coupled to the first member rotating section, the second member comprising a second member fixation section configured to be fixated to a second portion of the stomach wall;
- an operation device coupled to the first member rotating section, the operation device being configured to induce a rotation of the first member rotating section around the first axis;
- the first member fixation section being configured to describe a revolution around the first axis between a first position of the first member fixation section and a second position of the first member fixation section in response to the rotation of the first member rotating section;
- wherein
- each of the first member rotating section and the operation device is positioned below a first reference plane perpendicular to the first axis, and the first member fixation section is positioned above said first reference plane for at least a part of the revolution of the first member fixation section;
- and the stomach wall between the first portion and second portion is increasingly stretched when the first member fixation section revolves towards the second position of the first member fixation section.
