Abstract: A non-coring hair implantation needle is provided which provides for a smaller opening than a conventional hypodermic needle, and includes a bevel of shorter length. The needles are configured to provide a non-cutting feature, and aid in placement and retention of an implanted hair graft when the needle is withdrawn from the body surface. Furthermore, methods of fabricating needles includes bevels of shorter length and non-cutting features are disclosed.

Abstract: Devices and methods for applying tension to an area of skin are provided, for example, for follicular unit removal and implant in a hair transplantation procedure. The devices may include a frame with at least two skin contact members that hold to the skin. Also disclosed are various ways to apply a force displacing the skin contact members apart, thus creating tension in the skin. The devices and methods may incorporate suction, and/or barbs or microbarbs. The frame may surround the skin area with tensile forces applied outward in multiple directions or substantially uni-directionally. Adjusting members and indicators may be provided to control and display the tensile force applied to skin. The tensioning devices and methods may be incorporated into a robotic hair transplantation system.

Abstract: Devices and methods for applying tension to an area of skin, in particular for follicular unit removal and implant in a hair transplantation procedure are provided. The devices may include a frame with at least two skin contact members that hold to the skin. Also disclosed are various ways to apply a force displacing the skin contact members apart, thus creating tension in the skin therebetween. The devices and methods may incorporate suction that helps the skin contact members securely hold to the skin. Barbs or microbarbs also may be used to help secure the skin contact members to the skin. The frame may surround the skin area with tensile forces applied outward in multiple directions, or the frame may be a bifurcated pair of fingers that applies tension substantially uni-directionally. Adjusting members and indicators may be provided to control and display the magnitude of tensile force applied to skin. The tensioning devices and methods may be incorporated into a robotic hair transplantation system.
