Publication number: 20220362542Abstract: This invention provides an device for electrical stimulation of the spinal cord. The device has an electrode assembly with a sufficiently thin profile to be implanted between the pial surface of the spinal cord and the dura mater, and secured to the dura. Electrodes on the electrode assembly are directed towards the surface of the spinal cord, and connected through the dura to a signal generator located outside the dura. Following implantation, the subject is treated by transmitting electrical signals from the signal generator through the leads to the electrodes, stimulating the subject's spinal cord.Type: ApplicationFiled: August 1, 2022Publication date: November 17, 2022Applicants: University of Iowa Research Foundation, University of Virginia Patend FoundationInventors: Matthew A.

Publication number: 20190209852Abstract: An anchor for an electrical lead or other elongate medical instrument can include an anchor body. The anchor body can define an instrument passageway. The instrument passageway can extend from a first end of the anchor body to a second end of the anchor body. The anchor body can define one or more suture holes in the anchor body. A clamp can be included in or coupled to the anchor body. The clamp can include a first clamping flange and a second clamping flange. The first clamping flange and the second clamping flange can project laterally from the clamp. The clamp can include a clamping cavity extending about the instrument passageway. The clamp can be arranged to close such that changing a distance between the first clamping flange and the second clamping flange causes a dimension of the clamping cavity to decrease and hold the instrument within the instrument passageway.Type: ApplicationFiled: January 10, 2019Publication date: July 11, 2019Applicant: Heraeus Medical Components LLCInventors: Randall S.

Publication number: 20170065814Abstract: 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.Type: ApplicationFiled: September 16, 2016Publication date: March 9, 2017Inventors: Matthew Howard, Timothy Brennan, Brian Dalm, Marcel Utz, George T.

Patent number: 9055946Abstract: 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.Type: GrantFiled: November 25, 2009Date of Patent: June 16, 2015Assignee: Phraxis Inc.Inventors: Alexander Yevzlin, Randall S.

Patent number: 9053315Abstract: 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.Type: GrantFiled: June 28, 2012Date of Patent: June 9, 2015Assignee: Lenova Enterprise Solutions (Singapore) Pte.

Patent number: 7822959Abstract: The present invention relates to a method for the safe shut down of an operating system. The invention utilizes a shutdown-monitoring program that is running in an initiator operating system to periodically transmit and pass-through SCSI command to a SCSI target to determine if a shutdown operations is to be performed upon the operating system. In response to the SCSI command the SCSI target returns data back to the initiator operating system, wherein the shutdown-monitoring program analyzes the data. In the event that the shutdown-monitoring program determines that the operating system is to be shut down, then an operating system shutdown is initiated using at least one appropriate API that is provided by the operating system.Type: GrantFiled: January 9, 2007Date of Patent: October 26, 2010Assignee: International Business Machines CorporationInventors: Josep Cors, Russel R.
