Predicting Chronic Optimal A-V Intervals For Biventricular Pacing Via Observed Inter-Atrial Delay
US Patent:

International Classification:
A61N 1/05
US Classification:
607 9
Abstract:
Herein provided are methods for optimizing the atrio-ventricular (A-V) delay for efficacious delivery of cardiac resynchronization therapy. The A-V delay is set such that pacing-induced left ventricular contraction occurs following completion of left atrial (LA) contraction. This maximizes left ventricular filling (preload) which theoretically results in optimal LV contraction via the Frank-Starling mechanism. In CRT devices, the programmed A-V delay starts with detection of electrical activity in the right atrium (RA). Thus, a major component of the A-V delay is the time required for inter-atrial conduction time (IACT) from the RA to the LA. This IACT can be measured during implantation as the time from the atrial lead stimulation artifact to local electrograms in a coronary sinus (CS) catheter. Assuming that the beginning of LA contraction closely corresponds with the beginning of LA electrical activity, the optimal AV delay should be related to the time between the start of RA electrical activity and the start of LA electrical activity plus the duration of LA atrial contraction. Thus the inventors hypothesized that during atrial pacing the IACT measured at implantation correlated with the echocardiographically defined optimal paced AV delay (PAV).
Sternal Closure Wire For Sensing And Therapeutic Energy Delivery
US Patent:
8527069, Sep 3, 2013
Filed:
May 10, 2011
Appl. No.:
13/104534
Inventors:
Mehdi Razavi - Houston TX, US
Alan Brewer - Houston TX, US
Alan Brewer - Houston TX, US
Assignee:
Texas Heart Institute - Houston TX
International Classification:
A61N 1/00, A61B 5/04
US Classification:
607126, 600372, 600509, 607119, 607132
Abstract:
An embodiment includes a sensor coupled to a sternal closure wire. The sternal closure wire holds two sternum portions of a patient adjacent to one another and the first sensor senses a biological signal of the patient. An embodiment includes a current source coupled to a sternal closure wire. The sternal closure wire holds two sternum portions of a patient adjacent to one another, and the current source delivers an electrical current to the patient via the sternal closure wire. Other embodiments are described herein.
Introducer Sheath With Electrodes
US Patent:
8366615, Feb 5, 2013
Filed:
Oct 16, 2009
Appl. No.:
12/581101
Inventors:
Mehdi Razavi - Houston TX, US
Assignee:
Texas Heart Institute - Houston TX
International Classification:
A61B 5/00, A61B 5/04, A61B 5/02
US Classification:
600371, 600373, 600506
Abstract:
An apparatus comprises a sheath for introducing a catheter into a blood vessel, at least one electrode provided on the sheath, at least one other electrode; and a measuring device to which at least one pair of electrodes are coupled. The measuring device measures the impedance or conduction velocity between the first electrode on the sheath and the second electrode.
Sheath And Method Of Use
US Patent:
2011030, Dec 15, 2011
Filed:
Jun 14, 2011
Appl. No.:
13/160219
Inventors:
Mehdi Razavi - Houston TX, US
International Classification:
A61B 18/14
US Classification:
606 41
Abstract:
In an embodiment a sheath allows one to simultaneously ablate tissue, using a catheter located in the sheath, and remove fluid from a patient's pericardial space, via the same sheath, all without withdrawing the ablation catheter from the sheath. Applying pressure (positive or negative) to fenestrations in the sheath may allow one to withdraw fluid from the space, navigate the sheath within the space, and/or adhere the sheath to tissue in the space. Other embodiments are described herein.

International Classification:
A61B 6/00
US Classification:
600424
Abstract:
In an embodiment, an apparatus comprises a needle (e.g., hypodermic needle or trocar) and sensor (e.g., fiber Braggs grating sensor) coupled to a system to determine (e.g., in real time) stress and/or vibrations encountered by the needle. Consequently, various embodiments may (a) help identify nearby vessels, (b) determine whether the needle penetrated a hollow body structure, and (c) accurately guide needles towards a target structure (e.g., vessel). Other embodiments are described herein.
