Publication number: 20140303455Abstract: A cerebrospinal fluid (CSF) monitoring device for the detection of obstructions in real time through the collection of pressure data from an on-board pressure sensor. This system is designed to integrate into medical devices equipped with a CSF drainage system, such as implantable shunts. CSF analysis data can be transmitted in real-time wirelessly to a physician or can be stored on-board in a memory card and retrieved wirelessly at a later time. Information from the CSF sensors can be used by physicians to monitor CSF conditions known to cause shunt malfunction/obstruction such as elevated protein concentrations, evidence of an on-going or recent hemorrhage such as presence of heme proteins, and concentrations of administered medications/drugs over time. It can be used to monitor for CSF infections, in which increased pressure, increased temperature, CSF high protein and low glucose, would be suggestive of CSF infections.Type: ApplicationFiled: April 3, 2014Publication date: October 9, 2014Applicant: Pharmaco-Kinesis CorporationInventors: Yehoshua Shachar, Thomas Chen, Dan Murray, Robert Purnell

Patent number: 8827986Abstract: A remotely activated piezoelectric pump for delivery of biological agents to the intervertebral disc and spine in order to achieve spinal fusion. A spinal pump is implanted on the vertebrae of a patient and a spinal cage is inserted in between two adjacent vertebrae after removal of the vertebrae disc. A piezoelectric motor drives the pump and pushes osteogenetic agent through the spinal cage and into a sponge disposed within the cage. The pump is charged by an external removable induction belt worn by the patient. Delivery duration and delivery frequency may be changed before implantation of the spine pump according to the specific needs of the patient. The current device employs a mathematical model that enables the regulation as well as attenuation of the bone fusion process by extending and generalizing the model to enhance and optimize the delivery of osteogenetic agent in a regulated manner.Type: GrantFiled: October 19, 2009Date of Patent: September 9, 2014Assignee: Pharmaco-Kinesis CorporationInventors: Yehoshua Shachar, Thomas C.

Patent number: 8571805Abstract: A biosensor for detection of vascular endothelial growth factor (VEGF) hybridization uses an array of parallel capacitors to detect electrochemical binding of circulating VEGF to immobilized anti-VEGF monoclonal half-antibodies (a-VEGF mhAb). Binding of a-VEGF mhAb modulates the threshold voltage of a circuit, changing the impedance of the circuit. An electrode coated with a p-Si substrate enhances the affinity between the VEGF molecules. A fluid cell delivers VEGF samples onto the active surface of the chip. An array of parallel capacitors arranged in an interdigitated pattern detects the VEGF in the fluid. The detector provides an accurately measured and quantifiable rate of change of the VEGF molecules in vivo, providing real time feedback which is used to measure response of the tumor to delivered chemotherapeutic agents and biological response modifiers (BRMs) for the purpose of determining tumor burden and efficacy of the chemotherapy as part of a homeostatic loop for chemotherapy.Type: GrantFiled: June 22, 2010Date of Patent: October 29, 2013Assignee: Pharmaco-Kinesis CorporationInventors: Yehoshua Shachar, Winston Wu, Thomas Chen, Brett Jordan, Kyle Zimmerman, Herwin Chan, Paladin Luboff

Publication number: 20110295159Abstract: A vertebral processor designed to collect and interpret data from multiple surgically implanted accelerometers. Each accelerometer is surgically implanted into a vertebra of a patient utilizing a bone screw. Additional accelerometers are implanted in adjacent vertebrae. The data from the accelerometers is compared by an algorithm to determine the relative movement of the accelerometers implanted in adjacent vertebrae. Data is generated via the algorithm and compared against the expected behavior of the surgically implanted accelerometers as if they were connected to a rigid body, thus determining the level of success of a spinal fusion procedure for those adjacent segments. The apparatus may be utilized with or without spinal stabilization hardware, and with or without fusion cages or artificial discs. The vertebral processor is supplemented by an external system worn by the patient, which provides for an inductive charging power source and for data transfer.Type: ApplicationFiled: May 25, 2010Publication date: December 1, 2011Applicant: PHARMACO-KINESIS CORPORATIONInventors: Yehoshua Shachar, Thomas Chen, Winston Wu, Brett Jordan, Herwin Chan, Paladin Luboff, Kyle Zimmerman
