  • Patent number: 11045306
    Abstract: Method and apparatus for automated staging of hair grafts using a camera for capturing one or more images of a staging area constructed for holding the hair grafts, and a controllable robotic arm having an aspiration tip mounted at a tool end thereof. An image captured by the camera is processed to identify a position of a hair graft in the image, and subsequent to distinguishing between a base end and a hair end of the hair graft in the image, an aspiration point is defined based at least in part on position of either or both of the base end and the hair end. The robotic arm is controlled to move the aspiration tip to the aspiration point, for aspiration of the hair graft into the aspiration tip.

  • Patent number: 8062322
    Abstract: A hair transplant apparatus and a method for placing hair grafts into pre-made wounds capture a hair graft into a hair graft chamber readily aligned for implantation into the human scalp. The hair graft can be placed into the hair graft chamber manually or mechanically (e.g., by vacuum). A hair transplant apparatus includes a housing and a sliding rod within the housing. When the sliding rod is away from an open distal end of the housing in a first position, a hair graft can be placed into the spacing between an end of the rod and the open distal end of the housing. In a second position, the rod is advanced so the end of the rod becomes substantially flush with the distal end of the housing, thereby pushing the hair graft out of the housing and into the pre-made wound. Advantageously, the housing is aligned with the direction of the pre-made wound allowing the hair graft to slide easily into the pre-made wound without damage.

  • Publication number: 20090200772
    Abstract: A ski brake is attached to a ski to provide a controllable drag to the advance of a ski on a snow surface. A cable extending from a ski-pole mounted grip to the brake allows a skier to adjust the amount of drag. The position of the ski brake and thus the amount of drag can be controlled wirelessly as well.

  • Patent number: 7518724
    Abstract: Image data is acquired, processed, and/or displayed in accordance with an embodiment of the present disclosure to display, monitor, and/or demonstrate the progress of an experiment substantially in real-time and with high sensitivity. In one embodiment, at least one time-resolved value of spatially distributed polarization change data is provided and displayed. Advantageously, real-time processing and display of data is provided such that discussion and collaboration about the experiment may occur, time-resolved data is not lost, and resources are not wasted.

  • Patent number: 7452367
    Abstract: A hair transplant apparatus and method capture a hair graft into a hair graft chamber readily aligned for implantation into the human scalp. The hair graft can be placed into the hair graft chamber manually or mechanically (e.g., by vacuum). A hair transplant apparatus includes a gas-permeable stopper for utilizing gas flow to load and/or implant a hair graft. Another hair transplant apparatus includes a gas-permeable rod inside a housing. Vacuum may be utilized to load a hair graft into the hair graft chamber. The rod may be advanced toward an open distal end of the chamber so the end of the rod becomes substantially flush with the distal end, thereby pushing the hair graft out of the chamber and into the pre-made wound. Advantageously, the chamber is aligned with the direction of the pre-made wound allowing the hair graft to slide easily into the pre-made wound without damage.

  • Publication number: 20080216334
    Abstract: Apparatus for determining the status of hair bulk in an area of a scalp is operative to provide a metric over a sufficiently large area to permit revisiting with only negligible misalignment error. Accurate re-measurement of hair status in accurately identified areas produces a reliable metric for determining degree of hair loss and or the effectiveness of treatment.

  • Publication number: 20080051816
    Abstract: Apparatus for implanting single hair grafts in implant sites in a skin is adapted to apply a tiny adhesive dot in a manner to secure the implanted graft to the skin surface. The quick hardening of the adhesive allows the placement of implants in closely spaced, neighboring sites without causing dislodgment of previously implanted grafts. Illustrative apparatus for providing such implants comprises a hollow needle with a coaxial solid rod in a fixed position. The needle is moved along its axis for implanting a graft and a channel in the rod is positioned to deliver the adhesive dot.

  • Publication number: 20080033455
    Abstract: The harvesting of hair for a hair transplant procedure employs a hollow drill with an imaging system which permits alignment of center of the cutting edge of a hollow tube with the axis of the follicular unit to be removed. The diameter of the hollow tube is chosen such that when properly aligned, a follicular unit is removed without damaging critical anatomical portions of the follicles. In one embodiment, a medium in either liquid or vapor form is introduced to cool or freeze the skin over the surface of the selected follicular unit. In another embodiment, suction is applied to aid in the removal of the excised follicular unit. In still another embodiment, a robotic arm is employed to position the hollow needle in each instance. In another embodiment, an electrical current or heat is applied to kill the shaft of the selected follicular unit without its removal.

  • Publication number: 20040049206
    Abstract: A scalp tensioner for tensioning a scalp in a donor region of hair grafts, so as to facilitate harvesting of hair grafts. The tensioner includes at least two generally opposed support structures arranged to form an open space therebetween, and plural gripping mechanisms such as a linear array of teeth or needles so as to grip the scalp, with one such gripping mechanism being provided on each support structure. The support structures are slidingly engaged on guide rods, and coil springs coaxially mounted on the guide rods bias the support structures away from each other. The support structures are movable against the biasing action of the coil springs between a closed position at which the gripping mechanisms are engaged with the scalp, and an opened position which corresponds to a scalp tensioning position, and in which hair grafts can be harvested from the open space between the support structures.

  • Patent number: 5989279
    Abstract: A system for transplanting hair grafts from a donor region of a patient's scalp to a recipient region of the patient's scalp. The system includes harvesting N (N.gtoreq.21) strips of skin containing living hair follicles from the donor region of the patient's scalp, the N strips of skin being harvested simultaneously, and cutting the N strips of skin into hair grafts, the N strips of skin being cut simultaneously. The system also includes loading the hair grafts sequentially, bottom down, into a removable cartridge connected to an instrument for implanting the hair grafts into the recipient region of the patient's scalp, the hair grafts being loaded so as to create an air seal between the hair grafts and the cartridge, and implanting the hair grafts.

  • Patent number: 5860899
    Abstract: An apparatus for manipulating a user's back while supporting the user's back and hips includes a support defining a longitudinal axis, and a seat pad disposed along the support at a position corresponding to the user's hips for supporting the user's hips. The seat pad is rotatable around the longitudinal axis and has an attached seat belt for holding a user on the seat pad. A pair of handles are provided, one on each side of the seat pad, which are coupled to the seat pad and which are movable in reciprocal back-and-forth motion to control rotation of the seat pad around the longitudinal axis. A resistance device is coupled to the seat pad or elsewhere for providing resistance to reciprocal back-and-forth motion of the handles, and two mechanical stops are provided, one on each side of the apparatus, for limiting rotation of the seat pad. The mechanical stops each have plural settings for adjusting a maximum angle of rotation of the seat pad.
