Abstract: A suture assembly includes an elongated flexible body which may be either a single filament for a multiple strand braided or woven body, supporting a plurality of shaped tissue-engaging elements in a generally spaced arrangement thereon. A curved body having a sharp point is joined to one end of the flexible body while a straight pointed body is joined to the remaining end of the flexible body. In alternate embodiments, the tissue-engaging elements define a variety of cross-section shapes. In a further alternate embodiment, the tissue-engaging elements are divided into first and second oppositely facing sets to provide a bidirectional suture. In a still further alternate embodiment, the elongated flexible body supports an elongated tissue-bonding sleeve.

Abstract: A suture assembly includes an elongated flexible body supporting a plurality of frusto-conically shaped tissue-engaging elements in a generally spaced arrangement thereon. A curved body having a sharp point is joined to one end of the flexible body while a straight pointed body is joined to the remaining end of the flexible body. In alternate embodiments, the tissue-engaging elements are elliptical or polygonal in cross-section. In a still further alternate embodiment, the tissue-engaging elements are divided into first and second oppositely facing sets to provide a bidirectional suture.

Abstract: A toothbrush provides a head with bristles, a neck and a handle. An eccentrically rotational weight is engaged for rotation with a motor, the weight disposed within the head. The motor is disposed within the handle. The head and neck are integrally formed with a natural resonance frequency of vibration approximately equal to the rotational speed of the motor and synchronized therewith.

Abstract: A plastic molded, sit-on-top kayak of unique size and shape is disclosed with various components which provide multi-purpose usage. The kayak is especially useful for multi-purposes such as sailing kayak surfing, scuba diving, paddling, touring and electric motorized usage. The kayak has attachment points integrally molded that provide for these multi-purposes. An important component of the invention includes a removable backrest that additionally provides secure waterproof storage of the operator's personal items. The backrest can be easily removed and reattached securely in place when desired. The ability to easily remove a backrest or backpack option also enables a desirable compact capability for transportation and storage by a user. Additional benefits of this feature provide for a smaller profile for packaging and commercial transportation.

Abstract: A three-component, protective headgear or helmet, and circuits therefor is provided with a battery-powered LED head lamp, which may be used by construction workers, search and rescue persons, cyclists, police, fireman, and the like. The battery may be replaceable or rechargeable and has long-term, uniform output characteristics driven by unique circuitry.
