Abstract

A securing or holding element is incorporated into a gastric band to prevent slippage or migration of the gastric band after installation thereof around the stomach to restrict the size of a stoma opening. The securing element includes laterally extending, perforate end portions which are adapted to be secured by suturing to stomach tissue adjacent to the gastric band. The end portions of the securing element can be folded over onto the gastric band to reduce the cross sectional profile presented, and thus facilate introduction into the patient of the gastric band and securing element through a laparoscopic cannula during a laparoscopic procedure employing the band.

Claims

1. In combination, a gastric band adapted for laparoscopic placement around the stomach of a patient so as to control the size of the stomach opening and holding means for holding said gastric band in place around the stomach, said gastric band comprising a band member having a proximal end and a distal end, means for affixing the distal end in place at an intermediate part of the band member so as to form a looped portion including an inner stomach-facing surface, a fluid reservoir, an inflatable member located on said inner surface, and fluid communication means, extending between said inflatable member and said distal end of said band member, for providing fluid communication between said inflatable member and said reservoir so as to enable inflation of said inflatable member from said reservoir, and said holding means being secured to said band member and including oppositely directed portions and extending transversely to said band member, said portions being movable between a first position wherein the holding means is used to hold the gastric band in place and wherein said portions extend beyond said band member on opposite sides thereof so as to enable said portions to be affixed to tissue adjacent to the band and a second position wherein the holding means and the band member are adapted to be inserted through a laparoscopic cannula and wherein said portions are brought close to the band member so as to decrease the cross sectional profile presented by the holding means and the band member.

2. The combination claimed in claim 1 wherein at least said free end portions of said holding element comprises perforate members.

3. The combination claimed in claim 1 wherein said holding means comprises a plurality of said holding elements.

4. In combination, a gastric band adapted for laparoscopic placement around the stomach of a patient so as to control the size of the stomach opening and holding means for holding said gastric band in place around the stomach, said gastric band comprising a band member having a proximal end and a distal end, means for affixed the distal end in place at an intermediate part of the band member so as to form a looped portion including an inner stomach-facing surface, a fluid reservoir, an inflatable member located on said inner surface, and fluid communication means, extending between said inflatable member and said distal end of said band member, for providing fluid communication between said inflatable member and said reservoir so as to enable inflation of said inflatable member from said reservoir, and said holding means comprising at least one elongate holding element secured to said band member and extending transversely to said band member, said at least one holding element including oppositely directed, perforate free end portions, said free end portions being movable between a first position wherein the holding element is used to hold the gastric band in place and wherein said free end portions extend, beyond said band member on opposite sides thereof so as to enable said free end portions to be affixed to the stomach of the patient and a second position wherein the holding element and the band member are adapted to be inserted through a laparoscopic cannula and wherein said free end portions are folded over onto the band member to decrease the cross sectional profile presented by the holding element and band member.

5. In combination, a gastric band adapted for laparoscopic placement around the stomach of a patient so as to control the size of the stomach opening and holding means for holding said gastric band in place around the stomach, said gastric band comprising a band member having a proximal end and a distal end, means for affixing the distal end in place at an intermediate part of the band member so as to form a looped band portion including an inner stomach-facing surface, a fluid reservoir, an inflatable member located on said inner surface, and fluid communication means, extending between said inflatable member and said distal end of said band member, for providing fluid communication between said inflatable member and said reservoir so as to enable inflation of said inflatable member from said reservoir, and said holding means comprising at least one elongate holding element secured to said band member and including oppositely directed, perforate free end portions extending transversely to said band member.
