摘要:
A cement mixing and delivering sytem according to the present invention includes a tube (20) having an exit nozzle (50) and an aperture. An end plate ( plate 1) is adapted to seal against the interior of the tube aperture and the end plate (plate 1) has a plurality of needles (32) protruding therefrom into the tube (20). A rotatable and slidable divider ( plates 2 & 3) is received within the tube intermediate between the end plate ( plate 1) and the exit nozzle (50). The divider includes at least two plates ( plates 2 & 3). Each of the plates ( plates 2 & 3) has a plurality of apertures ( 36 & 38) that upon alignment the needles (32) of the first plate ( plate 1) are urged through the apertures (36 & 38) of the at least two divider plates ( plates 2 & 3).
摘要:
A central nervous system (CNS) catheter assembly (20) adapted for use as a ventriculostomy catheter and a spinal catheter includes a catheter body (28) defining at least one lumen (30) therethrough having a drug delivery branch (22) and a monitoring/sensing branch (24). The drug delivery branch (22) and the monitoring/sensing second branch (24) are in fluid communication with the lumen (30). The assembly further includes a filter assembly (36) disposed in fluid communication with the drug delivery branch (22) and a valve assembly (54) disposed in fluid communication with the monitoring/sensing branch (24). Also in accordance with the present invention, there is provided a temperature control system (170) for use in controlling the temperature of a location within the central nervous system such as the brain or the spinal cord. The system further includes a pump controller (180), a central processing unit or controller (194), a temperature sensing element (184), and a power supply (194) all operatively connected to the temperature control mechanism.
摘要:
Methods, systems and computer program products for cardiac pacing are provided. A defibrillation shock is applied to a heart of the patient and a pacing stimulation signal is automatically applied to the heart of the patient subsequent to termination of the delivery of the defibrillation shock. The pacing stimulation may be applied to the heart of the patient within about two seconds of termination of the defibrillation shock. The pacing stimulation signal may be applied to the heart of the patient subsequent to termination of the defibrillation shock irrespective of a characterization of electrical activity detected in the heart. The pacing stimulation may be single and/or paired pacing stimulation.
摘要:
A method and formulation for orally administering a bioactive agent which comprises encapsulating the agent in one or more biodegradable and biocompatible polymer or copolymer excipients to form a microcapsule which is capable of passing through the gastrointestinal tract unaffected and being taken up by the Peyer's patch.

摘要:
The administration of an Akt inhibitor in a suitable carrier to a rheumatoid arthritis synovial fibroblast affords a process for inducing rheumatoid arthritis synovial fibroblast apoptosis. The Akt inhibitor is administered either as an active molecule or as a gene sequence expressible within rheumatoid arthritis synovial fibroblast cells. The gene sequence can be encompassed within a gene vector such as an adenovirus. A process for assaying rheumatoid arthritis drug candidates for apoptosis affect includes exposing a culture of rheumatoid arthritis synovial fibroblast cells to a drug candidate and monitoring apoptosis in the culture in the presence of the drug candidate. Apoptosis in the culture is compared to apoptosis induced in a duplicate culture in the presence of a known Akt inhibitor.
摘要:
A method, and compositions for use therein capable, of delivering a bioactive agent to an animal entailing the steps of encapsulating effective amounts of the agent in a biocompatible excipient to form microcapsules having a size less than approximately ten micrometers and administering effective amounts of the microcapsules to the animal. A pulsatile response is obtained, as well as mucosal and systemic immunity.
