  • Patent number: 5359831
    Abstract: A molded suture retainer is provided for retaining and storing sutures. Both absorbable and nonabsorbable sutures fabricated from natural or synthetic materials can be advantageously retained and stored therein. The retainer is characterized by a wide spiraling oval passageway with minimal convolutions covered by a cover sheet. The length of the passageway is preferably proportional to 1/3 to 1/2 the overall length of the suture to be retained therein. Recesses are provided for receiving package stabilizing agents and/or needle parks. Sutures packaged in accordance with the invention exhibit fewer kinks and bends than prior packaged sutures.

  • Patent number: 5337505
    Abstract: A complete tool kit for cleaning firearms is disclosed. The tool kit utilizes a support rod constructed of rigid polymeric material. The tool kit further includes a rigid stainless steel brush, a combination brush composed of separate rigid polymeric and bronze brushes, a rotary bronze bore brush, a rigid spear point, as well as a rotary bore drying and cleaning attachment using a pair of cloth patches. The support rod is provided with threaded bores in its opposite ends for selectively mounting the noted brushes, spear point, and drying attachment in any selected positional array on the rod ends. A tubular foam rubber pad is positionable around either the support rod, an extension bar, or handle member to facilitate manipulation of a tool kit assembled from the kit. A plurality of support rod extension bars are attachable to either end of the support rod and to the facing ends of each other to increase the length of the support rod.

  • Patent number: 5335775
    Abstract: A suture display rack and procedure kit is provided which, upon folding, presents a plurality of stacked suture packages for seriatim review. The suture display rack is a substantially U-shaped structure with a floor portion and two opposing sidewall portions. A longitudinal fold line is provided in the floor portion parallel to the planes formed by the side walls such that, upon folding, the side wall portions may be brought into the same horizontal plane to form the base for the suture display rack. The suture packages may be loosely held in the rack or alternatively hinged to a side wall or contained in sheaths for ease of review and removal. The sheaths and suture packages can be sterilized separately from the display rack. The suture display rack may be securely adhered to a desired surface or may be set up in a portable manner.

  • Patent number: 5325405
    Abstract: A transceiver (100) is provided for transmitting during the transmission bursts (12) of a frame and receiving during the receiving time-slot windows (14). The transceiver (100) includes a receiver (320) for receiving a repeating radio frequency data (16) signal at any time within the receiving time-slot window (14) and for demodulating the repeating radio frequency data signal down to a baseband data signal. A data detector and clock recovery device (330) recovers the valid data (CHMP) from the baseband data signal. For controlling the receiver (320) and data detector and clock recovery device (330), a control circuit (400) modifies the receiving time-slot windows (14) to only receive and detect when valid data is expected (52).

  • Patent number: 5261210
    Abstract: A molded suture retainer is provided for retaining and storing long suture lengths. Both absorbable and nonabsorbable sutures fabricated from natural or synthetic materials can be advantageously retained and stored therein. The retainer is characterized by a wide spiraling oval passageway with minimal convolutions covered by a cover sheet. The length of the passageway is preferably proportional to 1/3 to 1/2 the overall length of the suture to be retained therein. In accordance with the method of the invention, sutures are doubled or tripled over and inserted into the retainer under vacuum. Sutures packaged in accordance with the invention exhibit fewer kinks and bends than prior packaged sutures.

  • Patent number: 5222978
    Abstract: Synthetic absorbable sutures are filled with a stabilizing agent, preferably a mixture of glycerol and calcium lactate, and inserted into a retainer having a narrow convoluted passageway. The retainer is inserted into an open foil pouch with a package stabilizing element, such as a paper sheet filled with stabilizing agent. The package containing the suture, retainer and package stabilizing element is sterilized, aerated, equilibrated to a relatively high moisture level, and sealed. Long lengths of suture and doubled-over and tripled-over suture may be withdrawn from the retainer with low force without damaging the suture. Bends and kinks in the suture are prevented so as to provide a synthetic absorbable suture having highly desirable out of package hand and feel. The suture as removed from the package exhibits improved tissue drag characteristics.

  • Patent number: 5222123
    Abstract: A method for redirecting calls to a cordless telephone wherein the user of the cordless telephone registers a location code at a call redirecting module. The location code informs the call redirecting module to redirect calls, that are directed to a first telephone unit, to a base station which is part of a network. The base station transmits the call, so that the cordless telephone receives the call if it is within the range of the base station. In the event that the cordless telephone receives the call, it transmits an acknowledgement signal. The base unit will cease to transmit the call if it does not detect the acknowledge signal within a predetermined time interval.
