Method And Apparatus For Measuring Volume Flow And Area For A Dynamic Orifice
US Patent:
6544181, Apr 8, 2003
Filed:
Dec 20, 1999
Appl. No.:
09/467165

Thomas Buck - Cambridge MA

International Classification:
A61B 802
US Classification:
600455, 600453, 600454, 600456, 7386125
Abstract:
Techniques are provided for obtaining selected instantaneous area measurements for a dynamic orifice through which blood is flowing in at least one direction, for obtaining instantaneous flow rates of blood passing through such a dynamic orifice and for obtaining flow volume for blood passing through a dynamic orifice. All of these techniques involve ensonifying a thin sample volume of blood flow exiting at the orifice, which volume is in a region of flow which is substantially laminar, such region normally being the vena contracta for the orifice, with an ultrasonic pulsed Doppler signal, receiving backscattered signal from blood within the sample volume and forming a power-velocity spectrum from the received backscattered signal. Techniques are disclosed for assuring that only laminar flow is looked at in forming the power-velocity spectrum. To obtain instantaneous area measurements, the power integral of laminar flow from the spectrum is formed, this power integral being proportional to an instantaneous cross-sectional area of the orifice.

International Classification:
A61B005/04
US Classification:
600/509000, 600/513000, 600/528000
Abstract:
The present invention provides systems and methods for performing automated auscultation and diagnosis of conditions of the cardiovascular system. The invention acquires an acoustic signal emanating from the cardiovascular system via an sensor. In addition, in certain embodiments of the invention an electrical signal, e.g., an electrocardiogram (EKG) is simultaneously acquired. The signals are digitized, and, optionally, filtered to remove noise. The invention then processes and analyses the signal(s) so as to provide a clinically relevant conclusion or recommendation such as a diagnosis or suggested additional tests or therapy. In preferred embodiments the system comprises: (1) a beat selection component that selects a plurality of beats for analysis, wherein each beat comprises an acoustic signal emanating from the cardiovascular system; (2) a time-frequency analysis component that performs a time-frequency decomposition of beats selected for analysis so as to identify or extract physiologically relevant features; and (3) a processing component that processes the information so at to provide a clinically relevant conclusion or recommendation. In preferred embodiments of the invention the system further includes an aggregation component that combines information obtained from a plurality of the beats selected for analysis. In one embodiment, the system diagnoses mitral valve prolapse.

International Classification:

US Classification:
600/437000, 600/465000
Abstract:
Techniques are provided for obtaining selected instantaneous area measurements for a dynamic orifice through which blood is flowing in at least one direction, for obtaining instantaneous flow rates of blood passing through such a dynamic orifice and for obtaining flow volume for blood passing through a dynamic orifice. All of these techniques involve ensonifying a thin sample volume of blood flow exiting at the orifice, which volume is in a region of flow which is substantially laminar, such region normally being the vena contracta for the orifice, with an ultrasonic pulsed Doppler signal, receiving backscattered signal from blood within the sample volume and forming a power-velocity spectrum from the received backscattered signal. Techniques are disclosed for assuring that only laminar flow is looked at in forming the power-velocity spectrum. To obtain instantaneous area measurements, the power integral of laminar flow from the spectrum is formed, this power integral being proportional to an instantaneous cross-sectional area of the orifice. For instantaneous flow rates, the instantaneous power-velocity integral is formed from the laminar flow of the spectrum, while flow volume is obtained from the timed integral of the instantaneous flow rate.
Cardiac Devices And Methods For Minimally Invasive Repair Of Ischemic Mitral Regurgitation
US Patent:

International Classification:
A61B 17/32
US Classification:
606 41, 606 42, 606 52
Abstract:
Novel apparatus and minimally invasive methods to treat atrioventricular valve regurgitation that is a result of tethering of chordae attaching atrioventricular valve leaflets to muscles of the heart, such as papillary muscles and muscles in the heart wall, thereby restricting the closure of the leaflets. Catheter embodiments for delivering and positioning chordal severing and elongating instruments are described.
Cardiac Devices And Methods For Percutaneous Repair Of Atrioventricular Valves
US Patent:
7559936, Jul 14, 2009
Filed:
Aug 13, 2003
Appl. No.:
10/640974
Inventors:
Robert A. Levine - Brookline MA, US
Assignee:
The General Hospital Corporation - Boston MA
International Classification:
A61B 17/10, A61B 17/08
US Classification:
606139, 606213
Abstract:
Novel apparatus and minimally invasive methods to treat The present invention provides methods and devices for grasping, stabilizing and fastening of cardiac valve leaflets to treat atrioventricular valve regurgitation, particularly mitral valve regurgitation, in the context of prolapse and/or flail mitral valve. Independent leaflet grasping elements provide the ability to reposition the leaflets for fastening and enough stability to prevent leaflet movement during fastening.
