Patent number: 9289133Abstract: The present invention provides methods and apparatus for determining a dynamical property of the systemic or pulmonary arterial tree using long time scale information, i.e., information obtained from measurements over time scales greater than a single cardiac cycle. In one aspect, the invention provides a method and apparatus for monitoring cardiac output (CO) from a single blood pressure signal measurement obtained at any site in the systemic or pulmonary arterial tree or from any related measurement including, for example, fingertip photoplethysmography. According to the method the time constant of the arterial tree, defined to be the product of the total peripheral resistance (TPR) and the nearly constant arterial compliance, is determined by analyzing the long time scale variations (greater than a single cardiac cycle) in any of these blood pressure signals.Type: GrantFiled: October 13, 2010Date of Patent: March 22, 2016Inventors: Richard J.

Publication number: 20100283484Abstract: Method and apparatus for real-time, 3-D image guidance of invasive surgical diagnostic tools and therapy. In this method, the 3-D distribution of electrical conductivity of the surgical region of interest are derived using images derived from magnetic resonance imaging (MRI) X-Ray Computed Tomography (CT) or other techniques. Current flows and voltages within the region due to applied currents from body surface electrodes at defined locations are simulated using a finite element method. During the surgical procedure, electrodes are placed at the same locations, and the surgical instrument is inserted into the region. By matching the potentials measured by the instrument to the simulated potentials, the instrument location may be identified in real-time.Type: ApplicationFiled: October 3, 2007Publication date: November 11, 2010Inventors: Richard J.

Patent number: 7792563Abstract: Method and apparatus for guiding ablative therapy of abnormal biological electrical excitation. The excitation from the previous excitatory wave is significant at the beginning of the next excitation. In particular, it is designed for treatment of fast cardiac arrhythmias. Electrical signals are acquired from recording electrodes, and an inverse dipole method is used to identify the site of origin of an arrhythmia. The location of the tip of an ablation catheter is similarly localized from signals acquired from the recording electrodes while electrical pacing energy is delivered to the tip of the catheter close to or in contact with the cardiac tissue. The catheter tip is then guided to the site of origin of the arrhythmia, and ablative radio frequency energy is delivered to its tip to ablate the site.Type: GrantFiled: March 16, 2006Date of Patent: September 7, 2010Assignee: Massachusetts Institute of TechnologyInventors: Richard J.
