Adjustable gastroplastry ring comprising a grip tab
First Claim
1. A gastroplasty ring configured to form a loop about a stomach having a stoma, comprising:
- a flexible band having an outside surface and a first end part and a second end part;
a closure system for reducing a diameter of an opening of the stoma by forming a loop around the stomach towards the first and the second end parts; and
at least one grab tab projecting from said outside surface of the loop, the at least one grab tab being configured to assist in joining and separating the two end parts, the at least one grab tab comprising;
a first grab tab, disposed proximal to the first end part, configured for separating the first end part from the second end part; and
a second grab tab, spaced from the first and disposed at the second end part, configured for joining the first end part and the second end part together and further configured to unlock the first end part from the second part;
said grab tabs being configured to be simultaneously manipulated in opposite directions during unlocking such that said ring experiences essentially symmetric opposed forces for providing partial and momentary slacking of the ring.

Abstract
The invention relates to a gastroplasty ring formed by a flexible band (2) which comprises a first end part (5) and a second end part (6) and which is intended to be closed around the stomach toward its two end parts by a closure system in order to reduce the diameter of the opening of the stoma by forming a loop, the band comprising an adjustable-volume annular compression chamber (3) connected, at the first end part, by an adjusting catheter (7) to a device for adjusting the internal pressure of said chamber, so as to adjust its diametral expansion, the ring comprising at least one grab tab (11, 12, 13) which projects toward the outside of the loop to make it easier for the two end parts to be brought together and parted.

14. A gastroplasty device comprising:
-
a flexible band having an outside surface and a first end and a second end, the band configured to form a loop about a stomach by the first and second ends at a time when the band is in a closed position; a system configured to releasably lock the first and second end in the closed position and to unlock the first and second ends; and grabbing means, projecting outwardly from said outside surface of the band, for manipulation by substantially opposing symmetric forces to move the first and second ends into, and out of, the closed position; wherein the grabbing means comprises a first tab located proximate the first end and a second tab located proximate the second end, the first and second tabs configured to be manipulated in opposite directions in order to move the first and second ends into the closed position. - View Dependent Claims (15, 16, 17, 18, 19, 20)
