摘要:
A method for treating intractable pain via electrical stimulation of the spinal cord. Remote, non-contact stimulation of a selected region of spinal cord is achieved by placement of a transceiver patch directly on the surface of that region of spinal cord, with said patch optionally being inductively coupled to a transmitter patch of similar size on either the outer or inner wall of the dura surrounding that region of the spinal cord. By inductively exchanging electrical power and signals between said transmitter and transceiver patches, and by carrying out the necessary electronic and stimulus signal distribution functions on the transceiver patch, the targeted dorsal column axons can be stimulated without the unintended stray stimulation of nearby dorsal rootlets. Novel configurations of a pliable surface-sheath and clamp or dentate ligament attachment features which realize undamaging attachment of the patch to the spinal cord are described.

摘要:
An anastomotic connector comprises a generally tubular access port having a first end and a second end and a main body portion in fluid communication with the second end of the access port that is structured to be deployed within a fluid passageway. The main body portion includes an expandable mesh frame defining a pair of flanges extending outwardly from the second end of the access port and a retention strap extending across the second end of the access port. The pair of flanges and the retention strap are structured to exert a radial force on an internal surface of a fluid passageway when the mesh frame of the main body portion is expanded within the fluid passageway. Furthermore, the pair of flanges and the retention strap allow the passage of fluid to the distal tissues that the native fluid passageway is supplying.

A method, system, and computer-readable storage media for granting a device access to a managed group are disclosed. Identification information may be exchanged between a management device in the managed group and a managed device through a secure first channel. If the identification information is verified by the management device, the managed device may be granted access to the managed group through the secure first channel. If access is granted, the managed device may access the managed group through a secure communication session on a network. If the identification information is not verified, the management device may send a cryptographic key to the managed device through the secure first channel. The cryptographic key may be used to create an encrypted communication session between the managed device and management device over the network.
摘要:
An optimal configuration of Internet Small Computer Systems Interface (iSCSI) sessions is automatically determined. A number of iSCSI target ports and a number of iSCSI initiator ports in a configuration are determined, and an ideal session count is determined for each iSCSI initiator port in order to maximize efficiency. All iSCSI initiator ports are traversed, and a determination is made which iSCSI initiator ports have less than the ideal session count. For those iSCSI initiator ports that have less than the ideal session count, the iSCSI target ports that are currently not logged into an iSCSI initiator ports that have fewer sessions than the ideal sessions. The steps of finding and attempting are repeated until a current total number of active sessions equals the number of iSCSI target ports.
摘要:
A low profile defibrillation catheter is disclosed which is much thinner than existing devices. The thin structure is provided by using the current conductor coil as a first electrode coil and the same materials as the conductor for the second electrode. The second electrode coil is bonded to the second conductor coil and wound in the same direction. The thin design is motivated by an electrical field analysis which reveals that the length of the catheter is the important determinant of defibrillation efficacy, and that the large radius and surface area of prior art devices were less beneficial.
摘要:
An electrode system for an implantable cardioverter defibrillator. The electrode system includes a conductive structure which is physically and electrically connected to the housing or can of the implantable cardioverter defibrillator and is used as an electrode in combination with an existing implantable cardioverter defibrillator electrode or electrodes. The electrode system provides a therapeutically significant increase in the effective surface area of the implantable cardioverter defibrillator's electrodes without requiring an additional header connection, feedthru, or cable.
摘要:
In an ISDN communications system, a remote station power detector circuit comprises a capacitor connected between center taps of transformers on the receive and transmit pairs of conductors. The capacitor stores energy delivered from a central DC power source. Two serially-connected opto-couplers form a discharge path for the capacitor. The first opto-coupler is periodically driven on to partially complete the discharge path. If the capacitor charge exceeds a predetermined minimum, the second opto-coupler will then be driven on, providing a logic level output usable by the remote station. Power consumption is minimized by the use of large resistors in series with the capacitor while reliable power detection is achieved by detecting accumulated charge on the capacitor. Dielectric isolation is provided through the use of opto-coupler circuits.

Apparatus and methods of assigning a physical adapter local to a computer to a virtual adapter in a computer through which the virtual adapter may receive and transmit data is provided. The apparatus and methods may include (1) providing a system including a plurality of computers coupled via a network, wherein a first computer of the plurality of computers includes a plurality of physical adapters and at least one virtual adapter; (2) for each virtual adapter in the first computer, assigning a rank to each physical adapter in the first computer; and (3) based on the ranks, testing one or more of the physical adapters in the first computer for connectivity to a physical adapter in a second computer with which a first virtual adapter is likely to communicate. Connectivity tests are started in a staggered manner that favors highly ranked physical adapters. Numerous other aspects are provided.
