A surgical thread for plastic surgery operations includes a clear section and multiple sharp projections on either side of the clear section. The clear section is devoid of projections while the projections on both sides of the clear section are inclined toward the clear section. There is also a method of performing plastic surgery operations using this surgical thread which includes threading the thread subcutaneously through tissue and/or muscle and in a manner such that the thread is folded back on itself as a loop or sling. The thread tension is then adjusted from both ends of the thread which extend out of two separate exit points to achieve a desired lift. The projections resist thread pull in the direction of the entry point and the clear section is located at the fold.

Absorbable implants for breast surgery that conform to the breast parenchyma and surrounding chest wall have been developed. These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self-reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof. The implants have suture pullout strengths that can resist the mechanical loads exerted on the reconstructed breast.
