DESCRIPTION OF THE INVENTION

[0018] In accordance with the first step of the present invention, an incision is made in the chin at a location along the lower front edge at a position referred to as the submental crease. The soft tissue overlying the mandible in this area is then dissected off. A channel is then drilled through the mandible or alternatively the Trocar/deployment shaft/metal tissue engagement piece/suture is inserted along the lower edge of the mandible through rigid periosteum. The next series of steps are outlined and illustrated as per the figures above.

[0019] Referring to FIG. 1, the components which comprise the tongue suspension of the present invention is illustrated. In particular, system 8 compromises a trocar 10 having a lure locking fitting 12 at one and shaft 4 deployment shaft 16 exiting the lure lock and 18 of trocar 10 and suture 20 exiting the other end of tracer 10.

[0020] FIG. 2 illustrates a portion of deployment shaft 17 exiting the front of trocar 10 with a metal tissue engagement piece 22 positioned at the leading edge of shaft portion 17.

[0021] FIG. 3 illustrates deployment shaft 16 with metal engagement piece 22 at the leading edge of suture 20, suture 20 having passed through deployment shaft 16.

[0022] FIG. 4 illustrates metal engagement piece 22 attached to the suture end after deployment shaft 16 has been removed from the tongue suppression system 8.

[0023] FIGS. 5-10 illustrate the steps used in the method of the present invention. In particular, FIG. 5 is an internal view of a human skull 30 and is the initial step in the suture deployment, process (a channel in the bone has already been drilled through the central portion of the mandible at the level of the genial tubercle, opening 32 being the introduction site). At this point, trocar 10 is the same structure as shown in FIG. 1.

[0024] FIG. 6 illustrates the system comprising trocar 10, deployment shaft 14, metal tissue engagement piece 22 and suture 20 passing through the drilled bone channel formed in the mandible into the soft tissue of tongue 34 at a predetermined position such that the tongue 34 is not completely pierced.

[0025] FIG. 7 illustrates when the device has reached the desired position.

[0026] FIG. 8 illustrates deployment shaft 14 with attached metal tissue engagement piece 22 pushed through deployment shaft 14. At this position, the health provider causes metal tissue engagement piece 22 to open (originally in the closed, or compact position).

[0027] FIG. 9 illustrates deployment shaft 14 with the attached engagement piece after trocar 10 has been removed.

[0028] FIG. 10 illustrates metal tissue engagement piece 22 after deployment shaft 14 has been detached and removed leaving the metal tissue engagement piece 22 ready for final anchoring to the drilled bone channel fully deployed.

[0029] In summary, the device of the present invention is composed of a multi-prong, “star-shaped” metal alloy (nitinal) soft tissue engagement piece that is attached to a thin cord of wire or suture that is placed percutaneously through an introducing trochar. This introducing trochar is small bore metal tube with a sharpened tip, similar to a large needle. It is guided to the proper position in the tongue through an introduction site adjacent to the genial tubercle of the mandible. This guided introduction is controlled for accuracy by the introducing trochar's pre-measured length and the skill and training of the operator. Once properly positioned, the device is deployed from the introducing trochar into position in the tongue by a deployment shaft that is slightly smaller than the bore of the introducing trocar. The introducing trochar is then removed, leaving the metal engagement piece with attached suspension cord and the deployment shaft. Proper tension is then applied to the suspension cord and deployment shaft to engage the multi-prong nitinol tissue engagement piece. Once properly engaged, the deployment shaft is disconnected and removed. This leaves the engaged multi-prong metal piece with attached cord in the tongue with the suspension cord anchoring end exiting the introduction site. The suspension cord anchoring end is then securely attached to the mandible with a bone anchor device. This bone anchor device is designed to allow for tightening of the suspension cord 6-12 months after initial placement. Alternatively, a second device may be deployed just under the trajectory of the first device, and with a slightly different vector, then tied to the first device cord across a mandible bone bridge.
