Endolumenal esophageal restriction device
View Patent ↗Generally described herein are apparatus, systems and methods related to a novel esophageal device implantable in the patient's body and designed to replicate the restrictive and satiety mechanism associated with gastric banding systems known in the art. The device can be a compliant and tubular-shaped and fixated within the gastro-esophageal lumen using tissue anchors.
1. An endoscopic device fixable to a patient's mucosal-serosal tissue for the treatment of obesity, the endoscopic device comprising:
a gastric band;
a tubular housing having a compliant portion and an anchoring portion, the housing having an inner annular wall and an outer annular wall which are both common to each of the compliant portion and the anchoring portion, wherein the compliant portion contains a filling, and wherein the inner and outer annular walls define aligned openings therethrough in the anchoring portion;
a tissue fixation component having:
a stem portion constructed to extend through the aligned openings in the anchoring portion and for penetrating the patient's mucosal-serosal tissue to fix the tubular housing with respect to the mucosal-serosal tissue,
a head portion attached to a first end of the stem portion to engage the inner annular wall of the housing for preventing the head from exiting the openings, and
a hook attached to the second end of the stem portion, the hook configured to receive the gastric band to prevent the gastric band from migrating with respect to the tubular housing.
