Abstract

A system and method of moving and stretching plastic tissue using dynamic force. A preferably non-reactive force applying component is adjustably attachable to one or more tissue attachment structures for securing the force applying component to the plastic tissue, providing a self adjusting system that is capable of exerting relatively constant tension over a certain distance.

Claims

1. A system for moving tissue of a patient, comprising:

(a) at least one anchor attachable to the patient'"'"'s tissue and comprising

(i) a generally planar base having a bottom surface, a top surface and a perimeter, and

(ii) attached to the base, opposed non-parallel structure that extends generally upward from the base top surface and that secures a force applying component,

(b) at least one elastic force applying component comprising an elongated length of monostrand and having two free ends, wherein the component is attached to the anchor at one of multiple alternative positions along the component without knotting to provide adjustable force, and

(c) a pressure sensitive adhesive layer attached to the bottom surface of the base of the anchor and extending beyond the perimeter of the planar base of the anchor, wherein the adhesive is adapted to attach the base to the tissue,

wherein the anchor further comprises, attached to the base and extending generally upward from the base top surface, at least one hook adapted to engage the force applying component and thereby apply force to the base.

2. A system for moving tissue of a patient, comprising:

(a) at least one anchor attachable to the patient'"'"'s tissue and comprising

(i) a generally planar base having a bottom surface, a top surface and a perimeter, and attached to the base and extending generally upward from the base top surface, an eye within a hook, the hook adapted to engage the force applying component and thereby apply force to the base,

(ii) attached to the base, opposed non-parallel structure that extends generally upward from the base top surface and that secures a force applying component,

(b) at least one elastic force applying component comprising an elongated length of monostrand and having two free ends, wherein the component is attached to the anchor at one of multiple alternative positions along the component without knotting to provide adjustable force, and

(c) a pressure sensitive adhesive layer attached to the bottom surface of the base of the anchor and extending beyond the perimeter of the planar base of the anchor, wherein the adhesive is adapted to attach the base to the tissue.
