Patent number: 8986214Abstract: The invention relates to a method for using tissue contact technology to optimize automated cardiac chamber mapping algorithms to both speed up the mapping process and guarantee the definition of the actual chamber limits. The invention further comprises a method for conveying tissue type information to such automatic mapping algorithms so as to allow them to adapt their point collection density within areas of particular interest. The method is enhanced by the use of a magnetic chamber that employs electromagnetic coils configured as a waveguide that radiate magnetic fields by shaping the necessary flux density axis on and around the catheter distal tip so as to push, pull and rotate the tip on demand and as defined by such automatic mapping algorithms.Type: GrantFiled: February 17, 2010Date of Patent: March 24, 2015Assignee: Magnetecs Inc.Inventors: Yehoshua Shachar, Bruce Marx, Leslie Farkas, Eli Gang, Laszlo Farkas

Patent number: 8684010Abstract: A guided medical propulsion capsule driven by strong electro-magnetic interaction between an external AC/DC magnetic gradient-lobe generator and a set of uniquely magnetized ferrous-conductive elements contained within the capsule. The capsule is navigated through the lumens and cavities of the human body wirelessly and without any physical contact for medical diagnostic, drug delivery, or other procedures with the magnetically guiding field generator external to the human body. The capsule is equipped with at least two sets of magnetic rings, disks and/or plates each possessing anisotropic magnetic properties. The external magnetic gradient fields provide the gradient forces and rotational torques on the internal conductive and magnetic elements needed to make the capsule move, tilt, and rotate in the body lumens and cavities according to the commands of an operator.Type: GrantFiled: December 8, 2010Date of Patent: April 1, 2014Assignee: Magnetecs CorporationInventors: Yehoshua Shachar, Laszlo Farkas, Bruce E.

Patent number: 8457714Abstract: 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.Type: GrantFiled: November 25, 2008Date of Patent: June 4, 2013Assignee: Magnetecs, Inc.Inventors: Yehoshua Shachar, Bruce Marx, Leslie Farkas, Laszlo Farkas, David Johnson, Eli Gang

Publication number: 20120310066Abstract: A system method that tracks one or more points on the surface of a cardiac tissue throughout a cardiac cycle and collect various types of data points which are then subsequently used to generate a corresponding model of the tissue and display the model as a 3D color coded image is described. In one embodiment, the system determines the position and orientation of a distal tip of a catheter, manipulates the catheter tip so as to maintain constant contact between the tip and a region of cardiac tissue using the impedance method, acquires positional and electrical data of the tip-tissue configuration through an entire heartbeat cycle, repeats the measurements as many times as needed in different tissue regions, and forms a 3D color coded map displaying various mechanical and electrical properties of the heart using the acquired data.Type: ApplicationFiled: June 7, 2012Publication date: December 6, 2012Applicant: MAGNETECS, INC.Inventors: Yehoshua Shachar, Bruce Marx, Laszlo Farkas, David Johnson, Leslie Farkas

Patent number: 8323270Abstract: 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.Type: GrantFiled: October 19, 2009Date of Patent: December 4, 2012Assignee: Pharmaco-Kinesis CorporationInventors: Yehoshua Shachar, Thomas C.

Publication number: 20120289822Abstract: The Lorentz-Active Sheath (LAS) serves as a conduit for other medical devices such as catheters, balloons, biopsy needles, etc. The sheath is inserted through a vein or other body orifice and is guided into the area of the patient where the operation is to be performed. The position and orientation of the LAS is tracked via an industry standard position detection system which senses electrical signals that are emitted from several electrodes coupled to the LAS. The signals received from the LAS are used to calculate an accurate and reliable assessment of the actual position of the LAS within the patient. The electrode signals also serve to create a reference frame which is then used to act as a motion compensation filter and fiducial alignment system for the movement of the LAS-hosted medical tool.Type: ApplicationFiled: April 18, 2012Publication date: November 15, 2012Applicant: MAGNETECS, INC.Inventors: Yehoshua Shachar, Bruce Marx, Leslie Farkas, David Johnson, Laszlo Farkas

Patent number: 7869854Abstract: A mapping and ablation catheter is described. In one embodiment, the catheter includes a MOSFET sensor array that provides better fidelity of the signal measurements as well as data collection and reduces the error generated by spatial distribution of the isotropic and anisotropic wavefronts. In one embodiment, the system maps the change in potential in the vicinity of an activation wavefront. In one embodiment, the mapping system tracks the spread of excitation in the heart, with properties such as propagation velocity changes. In one embodiment, during measurement, the manifold carrying the sensor array expands from a closed position state to a deployable open state. Spatial variation of the electrical potential is captured by the system's ability to occupy the same three-dimensional coordinate set for repeated measurements of the desired site. In one embodiment, an interpolation algorithm tracks the electrogram data points to produce a map relative to the electrocardiogram data.Type: GrantFiled: February 23, 2006Date of Patent: January 11, 2011Assignee: Magnetecs, Inc.Inventors: Yehoshua Shachar, Laszlo Farkas, Eli Gang
