Abstract

Abstract A cosmetic suture for use in attaching hair pieces to the human scalp consists of a suitably shaped needle having a hollow trailing shank which encompasses a short length of teflon tubing. A short length of stainless steel wire or ribbon is inserted through the teflon tubing to complete the suture unit. A porous plastic tip may be utilized to protect the needle point. The entire suture unit, together with a short bushing and wire subassembly, is placed in a thin transparent plastic sheath and heat sealed, after which the sheath may be placed in an outer envelope which is also sealed. The entire package thus completed is processed by a certified sterilizing system. During a single penetration of the scalp with the short suture assembly, the needle point is forced through the sterile plastic sheath and gradually the sheath is stripped from the suture assembly as the needle and teflon tubing pass through the scalp. Maximum protection against infection is thus afforded.
