Abstract:
A method for imaging an anatomical structure on a display, including acquiring an initial spatial representation of the anatomical structure and positioning an instrument in proximity to the anatomical structure. The method further includes determining a location of the instrument, and generating, in response to the location, an image of a part of the anatomical structure. The method includes appending the image to the initial spatial representation to display a combined spatial representation.
Abstract:
An embodiment of a disaster response system is disclosed that includes a communication and monitoring environment (CME). The CME includes an incident command infrastructure, and a communication infrastructure configured to exchange data with the incident command infrastructure. The communication infrastructure includes a network comprising a plurality of sensor assemblies that are configured to wirelessly communicate with the communication infrastructure. The sensor assemblies are configured to acquire data that includes at least one of environmental conditions, motion, position, chemical detection, and medical information. One or more of the sensors are configured to aggregate data from a subset of the plurality of sensors. The CME is configured to detect an incident based on at least the data acquired by the sensor assemblies.
Abstract:
A computer-implemented system for process control has two operating modes: normal mode and active procedure mode, with automatic transition between them. In normal mode, the operating system, firewall and anti-virus are fully operational. When entering a time-critical phase of a process, a process control application signals the operating system and utilities, whereupon transition to active procedure mode automatically occurs, in which access by the system services and by other applications to the resources of the computer is selectively limited in favor of the process control application. Upon completion of the procedure, the system automatically returns to normal mode.
Abstract:
An inventive system and method for touch free operation of an ablation workstation is presented. The system can comprise a depth sensor for detecting a movement, motion software to receive the detected movement from the depth sensor, deduce a gesture based on the detected movement, and filter the gesture to accept an applicable gesture, and client software to receive the applicable gesture at a client computer in an ablation workstation for performing a task in accordance with client logic based on the applicable gesture. The system can also comprise hardware for making the detected movement an applicable gesture. The system can also comprise voice recognition providing voice input for enabling the client to perform the task based on the voice input in conjunction with the applicable gesture. The applicable gesture can be a movement authorized using facial recognition.
Abstract:
During a minimally invasive deployment of a mitral valvuloplasty device into the coronary sinus near realtime tracking of the device is monitored to determine whether the device is compressing the left circumflex coronary artery or is likely to do so. In one embodiment of the invention, one or more position sensors are included in the catheter that is used to deploy the constricting implant and or in the implant itself. The position of the device is determined during deployment, and compared to the location of the left circumflex coronary artery, which may be determined by mapping relative to a pre-acquired image or by simultaneous intracardiac ultrasound imaging.
Abstract:
Cardiac tissue ablation is carried out by defining first regions containing first locations including ganglionated plexi in a heart of a living subject, and inserting a probe into the heart. The method is further carried out by detecting electrical activity in the heart via electrodes on the distal portion of the probe, defining second regions having second locations, wherein the electrical activity exhibits a dominant frequency that is higher than a predefined threshold, defining third regions having third locations, wherein the electrical activity exhibits complex fractionated atrial electrograms, constructing an electroanatomical map of the heart that defines intersections of the first regions and at least one of the second regions and the third regions, selecting ablation sites within the intersections, and ablating cardiac tissue at the ablation sites.

Abstract:
A method for treating atrial fibrillation in a heart of a patient includes placing an ultrasonic catheter in a first chamber of the heart; acquiring two-dimensional ultrasonic images of a second chamber of the heart and at least a portion of surrounding structures of the second chamber using the ultrasonic catheter placed in the first chamber; reconstructing a three-dimensional ultrasonic image based on the two-dimensional ultrasonic images; displaying the reconstructed three-dimensional ultrasonic image; identifying at least one key landmark on the reconstructed three-dimensional ultrasonic image; marking the least one key landmark on the reconstructed three-dimensional ultrasonic image; penetrating the septum for accessing the second chamber of the heart while using the marked at least one key landmark for guidance; positioning a sheath through the penetrated septum and within the second chamber of the heart; inserting an ablation catheter through the sheath and into the second chamber of the heart; and ablating a portion of the second chamber of the heart using the ablation catheter while under observation with the ultrasound catheter located in the first chamber of the heart.
Abstract:
A method for ablating tissue in an organ inside a body of a subject includes bringing a probe inside the body into a position in contact with the tissue to be ablated, and measuring one or more local parameters at the position using the probe prior to ablating the tissue. A map of the organ is displayed, showing, based on the one or more local parameters, a predicted extent of ablation of the tissue to be achieved for a given dosage of energy applied at the position using the probe. The given dosage of energy is applied to ablate the tissue using the probe, and an actual extent of the ablation at the position is measured using the probe subsequent to ablating the tissue. The measured actual extent of the ablation is displayed on the map for comparison with the predicted extent.
Abstract:
A method for implanting a medical device between tissue comprises the steps of providing a catheter having a body and a distal end thereof wherein the catheter includes an implantable device comprising a housing having a proximal end and a distal end and a longitudinal axis. The implantable device further includes a first set of anchoring members operatively connected to the proximal end of the housing and a second set of anchoring members operatively connected to the distal end of the housing. Both sets of anchoring members are movable between a collapsed position and a deployed position. Each set of anchoring members includes ring members connected to a housing of the device. Further steps of the method include inserting the distal end of the catheter into tissue and disposing the medical device at least partially from the distal end of the catheter. The first set of anchoring members are moved from the collapsed position to the deployed position and one side of the tissue is engaged with the tissue engaging surfaces of each ring member of the first set of anchoring member. The medical device is further disposed completely from the distal end of the catheter wherein the second set of anchoring members are moved from the collapsed position to the deployed position and the other side of the tissue is engaged with the tissue engaging surfaces of each ring member of the second set of anchoring members.
