Abstract

A therapeutic or diagnostic device is provided. The device includes a device body which is positionable within a lumen or passageway within a body and a tether which is attachable at a first end to the device body and at a second end to a tissue region not anatomically associated with the lumen or passageway.

Claims

1. A therapeutic device comprising:

(a) a conical device body being positionable within a stomach against a lower esophageal sphincter (LES); and

(b) an elastic silicone tether having a Shore A value of 70 or less and being attachable at a first end to a tip of said conical device body and at a second end to a tissue region within the oral or nasal cavity to thereby position said device body against said LES, said tether and said device body being configured such that when said device body is positioned against said LES, it is capable of blocking reflux through said LES without interfering with passage of a food bolus through said LES.

2. The device of claim 1, wherein said tissue region within said nasal cavity is a nasal septum.

3. The device of claim 1, wherein said tether includes radiopaque markings.

4. The device of claim 1, wherein said device body is an open cone capable of assuming a collapsed or an expanded state.

5. The device of claim 4, wherein said collapsed state enables nasal delivery of said device body.

6. The device of claim 1, wherein a length of said elastic silicone tether corresponds to a distance between said tissue region within the oral or nasal cavity and said stomach.
