International Classification:
A61M 31/00
US Classification:
604508, 604506, 604507, 604509, 6048901
Abstract:
A magnetically controlled pump is implanted into the brain of a patient and delivers a plurality of medicating agents at a controlled rate corresponding to the specific needs of the patient. The current invention comprises a flexible double walled pouch that is formed from two layers of polymer. The pouch is alternately expanded and contracting by magnetic solenoid. When contracted, a medicating agent is pushed out of the pouch through a plurality of needles. When the pouch is expanded, surrounding cerebral fluid is drawn into the space between the double walls of the pouch from which it is drawn through a catheter to an analyzer. Cerebral fluid drawn from the patient is analyzed. The operation of the apparatus and hence the treatment is remotely controlled based on these measurements and displayed through an external controller.

Method And Apparatus For Forming A Homeostatic Loop Employing An Aptamer Biosensor

View page
US Patent:
8145434, Mar 27, 2012
Filed:
Apr 10, 2009
Appl. No.:
12/422125
Inventors:
Josh Yehoshua Shachar - Santa Monica CA, US
Winston H. Wu - Alhambra CA, US
Leslie Farkas - Ojai CA, US
Thomas Chen - La Canada CA, US
Assignee:
Pharmaco-Kinesis Corporation - Inglewood CA
International Classification:
G06F 11/00
US Classification:
702 19
Abstract:
A novel architecture solid-state biosensor for label-free detection of vascular endothelial growth factor (VEGF) hybridization is presented. The new device is realized by forming a matrix array of parallel capacitors, thus allowing the realization of low-cost, portable, fully integrated devices. The detection mechanism is based on an electrochemical binding of circulating VEGF to an immobilized VEGF aptamer; whereby binding of these two compounds modulates the threshold voltage of a novel circuit, changing the impedance (capacitance) of the circuit. This novel circuit is further characterized by an electrode coded with a p-Si substrate, enhancing the affinity between the VEGF molecules and the aptamer. An apparatus forming a fluid cell is configured so as to enable the flow for delivering VEGF samples onto the active surface of the chip. The device has an array of parallel capacitors which act as an integrated, individual counter-electrode, computational apparatus which employs the sensory output over the time domain so as to enable detection, reporting and formation of a homeostatic loop for VEGF measurements.

US Patent:
8323269, Dec 4, 2012
Filed:
Oct 19, 2009
Appl. No.:
12/581756
Inventors:
Yehoshua Shachar - Santa Monica CA, US
Thomas C. Chen - La Canada CA, US
Leslie Farkas - Ojai CA, US
Bruce Marx - Ojai CA, US

Laszlo Farkas - Ojai CA, US
Assignee:
Pharmaco-Kinesis Corporation - Inglewood CA
International Classification:
A61K 9/22
US Classification:
6048911
Abstract:
A magnetically controlled pump is implanted into the cerebrospinal fluid of a patient and delivers a plurality of medicating agents at a controlled rate corresponding to the specific needs of the patient. The current invention comprises a flexible double walled lumen, intratumoral catheter which will be implanted. Spinal fluid drawn from the patient is analyzed. Medication is delivered on a continuous metronomic basis into the CSF via an internalized pump. CSF is removed and analyzed for VEGF and other cytokines via spectrophotometer analysis or a lab on a chip. The operation of the apparatus and hence the treatment is remotely controlled based on these measurements and displayed through an external controller.

Filed:
Oct 19, 2009
Appl. No.:
12/581770

Yehoshua Shachar - Santa Monica CA, US
Thomas C. Chen - La Canada CA, US
Leslie Farkas - Ojai CA, US
Bruce Marx - Ojai CA, US

International Classification:
A61K 9/22
US Classification:
6048911
Abstract:
A magnetically controlled pump is implanted into the brain of a patient and delivers a plurality of medicating agents mixed with Avastin at a controlled rate corresponding to the specific needs of the patient. The current invention comprises a flexible double walled pouch that is formed from two layers of polymer. The pouch is alternately expanded and contracting by magnetic solenoid. When contracted, the medicating agent Avastin is pushed out of the pouch through a plurality of needles. When the pouch is expanded, surrounding cerebral fluid is drawn into the space between the double walls of the pouch from which it is drawn through a catheter to an analyzer. In cases where a tumor resection is not performed, an intratumoral catheter will be implanted. Cerebral fluid drawn from the patient is analyzed. The operation of the apparatus and hence the treatment is remotely controlled based on these measurements and displayed through an external controller.

System And Method For A Catheter Impedance Seeking Device

View page
US Patent:
8457714, Jun 4, 2013
Filed:
Nov 25, 2008
Appl. No.:
12/323231
Inventors:
Yehoshua Shachar - Santa Monica CA, US
Bruce Marx - Ojai CA, US
Leslie Farkas - Ojai CA, US
Laszlo Farkas - Ojai CA, US
David Johnson - West Hollywood CA, US
Eli Gang - Los Angeles CA, US
Assignee:
Magnetecs, Inc. - Inglewood CA
International Classification:
A61B 5/05
A61B 17/00
US Classification:
600424
Abstract:
A tissue-contact seeking method and apparatus is described that enhances catheter position detection and control systems in making and maintaining continuous tissue contact in a highly dynamic frame, such as under the rigors of cardiac motion. Tissue-seeking logical routines use a tissue contact sensing system to advance a catheter to relatively continuous tissue contact, or detect obstacles, in cooperation with the catheter position detection and control systems. Additional logical routines are capable of optimizing the contact direction of the catheter tip by controlling the rotation angle and chamber position of the introducer.

Method And Apparatus For Controlling Catheter Positioning And Orientation

US Patent:
20080249395, Oct 9, 2008
Filed:
Apr 6, 2007
Appl. No.:
11/697690
Inventors:
Yehoshua Shachar - Santa Monica CA, US
Bruce Marx - Ojai CA, US
Leslie Farkas - Ojai CA, US
International Classification:
A61B 5/05
US Classification:
600409, 600424, 600426
Abstract:
A method and apparatus for detecting position and orientation of catheter distal magnetic element end while moving in a patient's heart is described. The apparatus includes magnetic sensors for to detect the magnetic field of a generated by the catheter tip. Each sensor transmits the field magnitude and direction to a detection unit, which filters the signals and removes other field sources, such as generated by CGCI coils and external medical hardware. The method allows the measurements of magnitude corresponding to the catheter tip distance from the sensor and the orientation of the field showing the magnetic tip orientation. Since the tip's magnetic field is not necessarily symmetric, the position and orientation computation technique are not independent of each other. Hence, an iterative calculation is used to converge to a solution. The method of determining tip position is calculated by triangulation from each sensor. In one embodiment, the tip orientation is calculated by an intersecting-planes algorithm. The orientation is used to adjust the distances from each sensor, and the process is repeated until convergence for both position and orientation is achieved. The resultant value provides the actual catheter tip position and orientation (AP). The actual position is further filtered by synchronizing the AP measurements with the QRS signal of the heart, allowing the operator and CGCI controller to view the organ as a static object.
