  • Patent number: 8882764
    Abstract: A method and apparatus for treating an intraosseous nerve. The method includes positioning a hollow shaft through the cortical shell of a vertebral body and into a cancellous bone region of the vertebral body. The hollow shaft includes an annular wall having a longitudinal bore therein, a proximal portion and a distal portion, and a first window extending transversely through the annular wall. An electrosurgical probe is advanced within the longitudinal bore from the proximal portion toward the distal portion. The electrosurgical probe includes a first treatment element at a distal end of the probe, wherein the first treatment element being in electrical connection with a power supply. The first treatment element is slidably disposed within the longitudinal bore so that the first treatment element is advanced radially outward from the window and shaft to affect treatment of the intraosseous nerve within the cancellous bone region.

    Abstract: A method for permanently removing hair utilizes the hair shaft and hair ducts to transmit light into the tissue sustaining the hair follicle, thereby permanently destroying or modifying the tissue in a manner which desirably mitigates hair growth. The method includes the steps of covering the patient's skin area with a high reflectance substance so as to substantially protect all skin components other than those sustaining the hair. The hair is optionally shaved or pulled out, and then the skin is illuminated with either a large-area electromagnetic radiation field for simultaneous destruction of multiple hair-follicles, or alternatively with a tightly-focused beam which destroys one hair at a time. Optionally, the beam may be rapidly scanned so as to destroy single hairs quickly in succession. The surrounding skin region is left substantially free of injury. This mitigates pain and enhances post hair removal healing.

  • Patent number: 5989267
    Abstract: The invention features a method of removing a hair, involving mechanically or chemically removing the hair to expose the follicle of the hair, and then treating the follicle to inhibit its ability to regenerate a hair. Removing the hair facilitates the uptake of a follicle-inactivating compound and thus allows for long-term inhibition of hair growth.

  • Patent number: 5951573
    Abstract: A depilatory device includes a pair of base members pivotally connected to one another and which support, at opposite ends of each base member, a pair of anchors that extend generally perpendicularly from the base members. A pair of string-like elongated elements arranged in mutually twisted engagement are attached to the anchors in such a manner such that the coils formed by the elongate elements travel linearly along the length of the depilatory device as the base members pivot with respect to one another. The result in an effective hair engagement and removal assembly.

  • Patent number: 5908425
    Abstract: A method and apparatus for hair removal are provided. A hand held, manually operated depilatory device removes hairs located along a length of a linear axis. A string-like, elongate element is positioned within a frame and may be removed for cleaning or replacement. Hair is engaged with and captured by a moving twisted engagement of an elongate, string-like element and pulled away and removed from the skin of a subject. The elongate element is removable and replaceable which improves hygienic maintenance and performance adjustment of the apparatus. The length of the twisted engagement and the number of its twists are adjustable by a user.

  • Patent number: 5899900
    Abstract: An epilator includes a pair of tweezers mounted at the leading end of a hollow wand body. An electrical circuit board for generating a radio frequency current is mounted in the trailing end of the wand body. The trailing end of the wand body is coated with a metabolized conductive coating to shield against electromagnetic interference. The tweezers are maintained in normally spaced apart relation to one another by a bias member that is compressed by a manually-operated actuator. The bias member includes an extension member that is in continuous contact with a first tweezer member and which makes contact with an electrical contact member mounted in the second tweezer member when the tweezer members are brought into hair-gripping relation to one another by actuator-driven compression of the bias member.

  • Patent number: 5868738
    Abstract: A method of removing multiple hairs and inhibiting future hair growth includes the steps of applying a conductive solution to the hair, applying power for a period of time sufficient to destroy the matrix area of the hair, and allowing the treated hair to either be removed immediately or to stay in the skin for a period of time sufficient for the chemical reaction induced at the matrix area to continue long enough to destroy the matrix area and prevent regrowth of the hair. The power may be applied through a conductive element of a comb. The comb is configured for carrying out the method. The comb may be provided with a moveable clamp for treating hair. The movable clamp may likewise be used to grasp and to remove treated hair when the grasped/clamped treated hair is moved relative to the skin by movement of the comb.

  • Patent number: 5833687
    Abstract: A pair of insulated, clamping electrode electrical power output tweezers for hair removal, comprising a pair of normally closed, spaced opposed, conductive arms; a conductive tip disposed adjacent a free end of one of the pair of conductive arms; a non-conductive material substantially enclosing each one of the pair of arms; the non-conductive material defining a power transmission area disposed adjacent to and spaced from the free ends; and the power transmission area being substantially free of the non-conductive material and being sufficiently large for contacting hairs.

    Abstract: A method of removing multiple hairs and inhibiting future hair growth includes the steps of applying a conductive solution to the hair, applying power for a period of time sufficient to destroy the matrix area of the hair, and allowing the treated hair to either be removed immediately or to stay in the skin for a period of time sufficient for the chemical reaction induced at the matrix area to continue long enough to destroy the matrix area and prevent regrowth of the hair. The hair removal is accomplished by use of a spring having at least two coils which are movable into engagement with each other. The two coils are configured for engaging and grasping hairs. When the coils clamp an engaged hair, and then moved relative to the skin, the hair is removed thereby. A device particularly suited for carrying out the invention includes coils which can be moved away from and toward each other for engaging hairs to be removed.

  • Patent number: 5824008
    Abstract: A helical fastener having a high retentive surface area is provided and has a first end for enhancing penetration into tissue and a second end comprising a coil sectioning a diameter of the fastener for receiving longitudinal and rotational forces. The helical fasteners are attached to body tissue by a fastener applicator having a proximal portion comprising a handle and an actuator and an elongate distal portion for housing a plurality of fasteners. A transferring action of the actuator provides longitudinal and rotational movement of the fasteners out of the distal portion and into body tissue.
