US 11,076,973 B2 · Intragastric helical prosthesis for treating obesity

Abstract

A transorally implantable intragastric helical prosthesis for treating obesity. The helical prosthesis has a primary lumen having a balloon element therein, and a secondary lumen having a spring wire element therein. The prosthesis also includes an end fitting. When deployed into the stomach of a patient, the prosthesis spontaneously reverts from a linear pre-deployment configuration to a helical post-deployment configuration by the biasing action of the spring wire element. Upon inflation of the elongated balloon element, the prosthesis unwinds, dynamically engaging and stretching the stomach wall, reducing the intragastric space, and slowing down gastric emptying, thus promoting a feeling of satiety, which may result in weight loss.

Dependent claims

An intragastric helical prosthesis for transoral placement into a user's stomach to treat obesity, the helical prosthesis comprising:

a helical assembly comprising;
a tubular elastomeric core element defining a first lumen and a second lumen;
a helical balloon element disposed in the first lumen;
and
a helical spring element disposed in the second lumen;
and
a proximal end fitting having a housing, the proximal end fitting coupled to:
the core element,
the helical balloon element, and
the helical spring element,
wherein the housing includes:
a central reservoir in fluid communication with the helical balloon element, and
at least two septums, wherein the at least two septums provide fluid access to the central reservoir.
