International Classification:

A46B 1302

US Classification:

15 221, 15 28

Abstract:

A brush tip for a motorized toothbrush has a first brush head and a second brush head. The second brush head encircles the first brush head. A shaft has two cranks, each engaging one of the brush heads. Continuous same-direction rotation of the shaft causes the brush heads to counter-rotate about a common axis. Distal ends of the first set of bristles on the first brush head form a circular pattern and the distal ends of the second set of bristles on the second brush head form an elliptical pattern.

International Classification:

A61F 2/44

US Classification:

623 1713, 623 1714, 623 1715, 623 1716

Abstract:

A spinal surgical prosthesis such as an artificial disc having a pair of upper and lower plate members, a flexible disc interposes therebetween and a rigid collar made of a bio-compatible and bio-resorbable material surrounding the flexible disc between the upper and lower plate members. Prior to the resorption of the collar, the collar serves to provide stability to the flexible disc for enhancing osteo-integration of the prosthesis with adjacent vertebrae. Subsequent to the resorption of the rigid collar, the flexible disc provides flexibility and compressibility while maintaining the proper inter disc space and lordosis or kyphosis between adjacent vertebrae.

Appl. No.:

11/974653

Inventors:

Ladislau Biro - Metuchen NJ, US
Howard Cohen - Hoboken NJ, US
Mathew Cohen - Long Beach NY, US

International Classification:

A61F 2/44

US Classification:

623 1715

Abstract:

An improved artificial spinal implant system for replacing a disc or vertebral body that provides adjustability in height, and provides support and stability of the spine with proper lordosis or kyphosis, osseous-integration of the implant, and motion preservation (if desired) of the adjacent vertebrae while preserving the space. Motion preservation is achieved with compressible and/or tiltable artificial discs.

Appl. No.:

6/644731

Inventors:

Howard Cohen - Brooklyn NY

International Classification:

A61C 800
A61C 1300

US Classification:

433175

Abstract:

A material and method are disclosed facilitating the forming of impressions of teeth and/or supporting structures, such as the alveolar ridge to be duplicated and restored. An elastomeric impression material, preferably subject to photochemical or chemical curing, is provided, such for example as formed from polyesters, polyethers, polysulfides, silicones, and ethylene imines, or derivatives thereof, containing a filler material, such as talc, calcium carbonate, colloidal silica, glass, quartz, acrylates, etc. , and impregnated with a hemostatic agent such as a vasoconstrictor or astringent or the like with the impression material serving to maintain subgingival tissue in a retracted condition without bleeding, so as to permit an impression to be taken of a tooth surface area and volume extending below the gumline, without requiring use of gum retracting cords or bands. In use, a portion of the impression material in a cord, ring or rhomboid shape, or the like, is wedged between the gum and the tooth to conform to the contour of the tooth below the gum and cured by chemical or photochemical means. This procedure is followed by the taking of an impression material adhering to the impression material below the gum, thereby providing an exact duplication of the tooth, both above and below the gum.

Appl. No.:

6/054943

Inventors:

Howard Cohen - Brooklyn NY

International Classification:

A46B 1302

US Classification:

15 28

Abstract:

A power driven brush assembly for cleaning teeth or the like. The brush assembly is formed with a hollow handle element containing drive means coupled to a power transmission extending from the handle element through a handle extension which carries a plurality of brush supporting members remote from the handle element. A plurality of brushes, one for each brush supporting member, is provided, with at least one of said brushes contoured with a cup-shaped cavity at a free end thereof remote from said brush support to implement the facility with which the outer edges of the brush may be bent to approximate the contours of the surface to be brushed. A method based on the same inventive concept is also disclosed for implementing the facility with which a surface may be brushed. This is accomplished by forming a plurality of brushing members with relatively unrestrained brushing portions free to flex to and from a longitudinal axis of the brushing member, and mounting the brushing members for rotation about the longitudinal axis thereof; and thereafter driving the brushing members to bring the relatively unrestrained brushing portions over the surface to be brushed with adjacent brushing members rotating in opposite directions.

International Classification:

G01B 310

US Classification:

33138

Abstract:

An illuminated retractable tape measure has a casing which contains a coiled tape rule whose free end extends through an opening in the casing. A lock arrangement locks the tape against automatic retraction into the casing. In the lock arrangement, a locking member is mounted in the casing with an end thereof engageable with the tape to hold the same against a portion of the casing in a locking position. The end of the locking member is moved out of engagement with the tape when an unlocked position is established. A slide actuator pivots the lock member between its locked and unlocked positions. A small lamp or LED is incorporated in the casing for illuminating the ruling on the tape measure, and the actuator closes a switch when the actuator is moved to its locked position to light the lamp. This feature facilitates reading measurements on the tape measure, especially in adverse lighting conditions. A flexible resilient circuit board serves as the switch for connecting the lamp or LED to a power cell when the slide actuator is moved to its locked position.
