Abstract
Methods and devices for repositioning the arytenoid cartilage of a human subject are disclosed.
Claims25
A device for repositioning a human subject's arytenoid cartilage, comprising:
- a biocompatible wire comprising:
- an uncoiled, pliable proximal portion extending along an axis and having one or more recesses or protrusions positioned therealong;
- and
- a coiled distal portion terminating in a tip that is sufficiently sharp to penetrate human cartilage;
- wherein the wire is sized and shaped such that it permits repositioning of the arytenoid by up to 10 millimeters while the tip engages the subject's arytenoid cartilage and while the proximal end is exterior to the subject's paraglottic space;
- and
- wherein the wire is sized and shaped such that it permits the tip to engage the subject's arytenoid cartilage while the proximal end is secured to the subject's thyroid cartilage.

A device for repositioning a human subject's arytenoid cartilage, comprising:
- a biocompatible wire consisting essentially of:
- an uncoiled, pliable proximal portion extending along an axis and having one or more recesses or protrusions positioned therealong and
- a coiled distal portion terminating in a tip that is sufficiently sharp to penetrate human cartilage;
- wherein the wire is sized and shaped such that it permits repositioning of the arytenoid by up to 10 millimeters while the tip engages the subject's arytenoid cartilage and while the proximal end is exterior to the subject's paraglottic space;
