Title: Implantable prosthesis
Inventor: CAPUZZIELLO THOMAS J
IPC: A61F2/00
Filed: 2001-09-13
Granted: 2009-11-03
Abstract: An implantable prosthesis and a method of repairing an anatomical defect, su ch as a tissue or muscle wall defect, by promoting tissue growth thereto, while limiting the incidence of postoperative adhesions between a portion of the prosthesis and tissue or organs. The prothesis is formed of a biologically compatible, flexible layer of repair fabric suitable for reinforcing tissue or muscle and closing anatomical defects, and a barrier layer for physically isolating at least a portion of one side of the fabric from areas likely to form adhesions. A peripheral barrier extends about at least a portion of the outer peripheral edge of the repair fabric to inhibit adhesions between the outer peripheral edge and adjacent tissue and organs. The repair fabric may include an outer margin that has been melted and resolidified to render the outer peripheral edgte substantially impervious to tissue ingrowth. The barrier layer may be joined to the repair fabric with connecting stitches formed from PTFE to inhibit the formation of adhesions thereto.

Abstract: The cosmetic dispenser is comprised of a barrel that is closed at a lower end by a screw and elevator assembly and on the upper end by an integrally molded top wall. The integrally molded top wall has a weakened area at its periphery and a gripping means such as a loop whereby the top wall can be removed by severing the weakened area. The removed top wall is discarded and the screw turned to raise a portion above the sidewalls. The integrally molded top wall can be integrally molded with the barrel or it can be integrally molded to an adaptor which fits onto the top of the barrel to provide a compound curved top edge for comfort in applying the cosmetic to a skin surface. In this latter embodiment the top wall has a peripheral weakened area whereby the top wall is removed by severing this top wall at the peripheral weakened area. The structure of these embodiments provides a positively sealed and easily opened cosmetic dispenser.

Title: System and method for establishing vascular access
Inventor: MACKENZIE ANDREW J
IPC: A61M25/00
Filed: 2001-11-28
Granted: 2009-08-04
Abstract: Systems, kits, and methods for establishing vascular access are described. A system may include a needle, a radially expandable sleeve and a dilator. The methods include creating an initial tissue tract to a target blood vessel with a radially expandable sleeve mounted on a needle. Upon removal of the needle, the dilator is then passed through the radially expandable sleeve to effect radial expansion of the sleeve. Use of the sleeve reduces the risk of injuring tissue surrounding the tissue tract by lessening the axial forces imparted to the tissue. Kits comprise at least the radially expandable sleeve together with instructions for use.

Abstract: A method and corresponding apparatus for encoding a sequence of bits for transmission as symbols, some of the bit positions of the symbols having a higher bit error rate than other bit positions. The method includes: a step (31, 32, 41, 42) of providing a plurality of sequences of bits using a convolutional encoder (31, 41), in response to a sequence of input bits, each sequence of bits being defined by a predetermined generator polynomial having a predetermined level of sensitivity to puncturing; and a step (33, 44) of mapping the bits of each sequence of bits to symbol positions based on the level of sensitivity of the generator polynomial defining the sequence of bits. With interleaving, the mapping of bits of each sequence of bits to symbol positions (33, 44) can precede a symbol interleaving step (34), or it can follow a bit interleaving step (43).

Abstract: Un appareil et un procédé pour traiter des données de mesure d'audimat permettent de détecter (Fig. 2) et de corriger un ou plusieurs codes horaires de diffusion défectueux. Les codes horaires défectueux sont identifiés par le calcul d'au moins un premier ensemble d'intervalles entre un ensemble de temps de lecture qui ne sont pas obligatoirement consécutifs et dont chacun correspond à un ou plusieurs codes horaires extraits d'un signal de diffusion (30). Le premier ensemble d'intervalles est comparé à un deuxième ensemble d'intervalles entre les codes horaires pour identifier si un ou plusieurs deuxièmes intervalles ne répondent pas à un critère prédéterminé. Au moins un des codes horaires associés à chacun des deuxièmes intervalles qui ne correspondent pas aux critères de code horaire est identifié comme défectueux. Le procédé utilisé pour calculer un code horaire corrigé consiste à utiliser l'amplitude du premier intervalle correspondant pour calculer le code horaire corrigé.

Abstract: A new class of imidazolines as 4-position acids or esters with very potent anti-inflammatory as well as antimicrobial activity is described. The synthesis of these imidazolines includes a multicomponent reaction applicable to a combinatorial synthetic approach. The combination of these two key characteristics provides an effective therapeutic drug in the treatment of septic shock as well as many other inflammatory (arthritis and asthma ) and infectious disorders. The use of this novel class of non-steroidal agents as anti-inflammatory agents ( for the treatment of asthma, etc.), antibacterial agents, and antiseptic agents is described. The compounds are also useful in the treatment of tumors ( such as cancers ). The imidazolines are potent inhibitors of the transcription factor NF-kB as potent activity against the Gram (+) bacterium. The compositions are also useful for treating autoimmune diseases and for inhibiting rejection of organ and tissue transplants.

Abstract: A gas detection sensor system including active and reference elements (Rsense, Rref) are arranged in a modified bridge circuit (12, 14, 22, 24) which allows power (Vbat) to be supplied separately to the active and reference elements (Rsense, Rref). A digital processor (30) monitors the resistances of the elements (Resense, Rref) to control a pulse-width modulator supplying power to the elements, thereby maintaining nearly constant temperatures in the sensor elements (Rsense, Rref), and to translate the decrease in power needed to maintain constant temperature on the catalytic element into an output proportional to the concentration of combustible gas in air. The system periodically measures the resistance of the elements (Rref, Rsense) and is able to dual operating modes of catalytic-bead detector. One active or reference element (Rsense, Rref) can alternately measure low concentrations of combustible gases up to the lower explosive limit (LEL) or measure high concentrations, up to 100% by volume.
