Pharyngeal tissue stabilization
View Patent ↗A patient's pharyngeal wall is treated by inserting an expander member into the airway and positioning an active portion of the expander member in opposition to portions of the pharyngeal wall to be treated. The expander member is activated to urge the wall portions outwardly to an outwardly displaced position. The expander member is then deactivated while leaving the wall portions in the outwardly placed position and the expander member is removed from said airway. A further aspect of the treatment includes stabilization of at least a portion of the pharyngeal wall after compression of portions of the wall.
1. A method of implanting an apparatus in a pharyngeal wall, comprising the steps of:
providing at least one apparatus including a suture, the suture having end portions and a non-resorbable portion, wherein only the end portions are entirely covered with a resorbable material;
implanting the suture in tissue of the pharyngeal wall such that only the end portions extend out of the pharyngeal wall; and
affixing the suture to at least one vertebra by securing the end-portions at a location substantially outside of the pharyngeal wall;
wherein following resorption of the end portions, the non-resorbable portion is fully recessed behind the pharyngeal wall, the non-resorbable portion providing mechanical stabilization of the tissue of the pharyngeal wall.
2. A method according to claim 1 , wherein the step of providing at least one apparatus includes providing an apparatus comprising a plastic material, and/or a metal material, and/or a fabric material, and/or a ceramic material, or a combination thereof.
3. A method according to claim 1 , wherein the step of providing at least one apparatus includes providing an apparatus comprising a material having a spring-like mechanical property.
4. A method according to claim 1 , wherein the step of providing at least one apparatus includes providing an apparatus comprising material having an elastic mechanical property.
5. A method according to claim 1 , further including bracing the tissue in the pharyngeal wall against collapse.
6. A method according to claim 1 , further including stabilizing the tissue in the pharyngeal wall against collapse.
7. A method according to claim 1 , wherein the step of implanting the suture includes implanting the suture in compressed tissue of the pharyngeal wall.
8. A method according to claim 1 , further including compressing the tissue of the pharyngeal wall and implanting the suture in the compressed tissue of the pharyngeal wall, wherein the non-resorbable portion stabilizes the compressed tissue of the pharyngeal wall.
9. A method according to claim 1 , wherein the step of implanting the suture includes implanting the suture such that only the end portions extend out of the pharyngeal wall into a patient's airway passage.
10. A method according to claim 9 , wherein the step of securing the end portions of the suture includes tying off the end portions in the patient's airway passage.
