Tongue suspension system with hyoid-extender for treating obstructive sleep apnea
First Claim
1. A system for treating obstructive sleep apnea comprising:
- a first implantable element having a first free end, a second free end, and a center section located between said first and second free ends, said center section being implanted in a tongue and said first and second free ends extending beneath the tongue into inframandibular musculature;
a second implantable element having an anterior end, a posterior end, an anchor point located at the anterior end, first and second laterally extending stabilizing arms adjacent the anterior end and posterior to said anchor point, an elongated shaft posterior to said first and second stabilizing arms and extending toward the posterior end of said second implantable element, wherein said elongated shaft is split adjacent the posterior end of said second implantable element into a first arm having a posterior end including a first hyoid bone engaging element having a first concave surface and a second arm having a posterior end including a second hyoid bone engaging element having a second concave surface, wherein said second implantable element is implanted in inframandibular musculature with said anchor point located nearer an anterior end of said inframandibular musculature, and said first and second concave surfaces located nearer a posterior end of said inframandibular musculature and engaging an anterior surface of a hyoid bone, said elongated shaft extending posteriorly from said anchor point, and said elongated shaft extending between muscle planes in the inframandibular musculature, wherein said first and second free ends of said first implantable element are attached to said anchor point at the anterior end of said second implantable element.

Abstract
A system for treating obstructive sleep apnea includes a first element implantable in a tongue and a second element implantable between muscle planes of an inframandibular region. The second element has a first end coupled with the first element and a second end coupled with a hyoid bone for preventing the base of the tongue from collapsing against an opposing pharyngeal wall during sleep. The first and second implantable elements have outer surfaces that are substantially impermeable to tissue in-growth to allow for post-surgical adjustment or removal, if necessary. The first implantable element is elongated and includes a first end, a second end, and a center section located between the first and second ends. The center section is implantable in the tongue, and the first and second ends of the first implantable element are advanceable beneath the tongue for being coupled with the anterior end of the second implantable element.

17. A method for treating obstructive sleep apnea comprising:
-
providing a tongue suspension element having a center section and two free ends; implanting the center section of said tongue suspension element in a tongue; advancing the two free ends of said tongue suspension element beneath the tongue and into inframandibular musculature; positioning the two free ends of said tongue suspension element in the inframandibular musculature located beneath the tongue; providing a hyoid bone extender having an anterior end, a posterior end, an anchor point located at said anterior end, first and second laterally extending stabilizing arms adjacent said anterior end and posterior to said anchor point, an elongated shaft posterior to said first and second stabilizing arms and extending toward said posterior end of said hyoid bone extender, wherein said elongated shaft adjacent the posterior end of said hyoid bone extender is split into a first arm having a posterior end including a first hyoid bone engaging element having a first concave surface and a second arm having a posterior end including a second hyoid bone engaging element having a second concave surface; implanting said hyoid bone extender between muscle planes in the inframandibular musculature located beneath the tongue so that said anchor point is located nearer an anterior end of said inframandibular musculature, said first and second concave surfaces are located nearer a posterior end of said inframandibular musculature, and said elongated shaft extends posteriorly from said anterior end of said hyoid bone extender; anchoring the two free ends of said tongue suspension element positioned within the inframandibular musculature to said anchoring point at said anterior end of said hyoid bone extender; and coupling said first and second concave surfaces at the posterior ends of said first and second split arms with a hyoid bone for moving a posterior surface of the tongue away from an opposing surface of a pharyngeal wall. - View Dependent Claims (18, 19, 24, 25)
