Dr. Theodore Abraham is associate chief of cardiology at Johns Hopkins Hospital, specializing in hypertrophic cardiomyopathy, the leading cause of sudden death among young athletes. As the director of the Johns Hopkins Hypertrophic Cardiomyopathy Center of Excellence and the Athletic Heart Clinic, Dr. Abraham founded Heart Hype, a program that screens local high-school athletes for potentially serious heart issues. He holds several patents for image-guided catheters and ultrasound-related devices, and is director of the Johns Hopkins Echocardiography Programs.
Dr. Abraham attended medical school in Bombay, India. He completed his internship and residency at Wake Forest University in North Carolina and pursued fellowships in echocardiography research at Wake Forest, clinical cardiology at the University of Texas, Southwestern, and in echocardiography and muscle physiology at the Mayo Clinic, where he was a Mayo Scholar. Dr. Abraham joined Johns Hopkins University in 2004. He is the author of nearly 150 publications including over 100 peer-reviewed articles as well as book chapters and editorials, and serves on the editorial boards of several journals, including Circulation: Cardiovascular Imaging and Cardiology Journal.

Wired and Wireless Remotely Controlled Ultrasonic Transducer and Imaging Apparatus
Patent # US8038622 B2 | 10/18/2011
A remotely manipulatable transducer element or linear transducer array for use with a remote work station including a display permits an operator of an ultrasound system to be remotely located from a patient. The transducer or linear transducer array comprises an assembly within a housing for fixation to a human body and intended to be placed one time and then remotely manipulated in directions of rotation, twist, and linearly in first and second perpendicular directions within a plane parallel to the surface of the human body under study. In one embodiment, the housing comprises a motor and a linear transducer array which are mounted to a rotor of the motor via an optional gear assembly for rotation, for example, in a range of 180 degrees so that multiple planes of imaging can be obtained, for example, of a heart or other body organ. The remotely manipulatable transducer or transducer array assembly may comprise a wireless transceiver having a unique identifier for communication with one or more work stations, each having a unique identifier.
Wired or Wireless Remotely Controlled Ultrasonic Transducer and Imaging Apparatus
Patent # CA2693730 C | 07/16/2013
A remotely manipulatable ultrasound transducer element or transducer array permits an operator of an ultrasound system to be remotely located from a patient and yet remotely control the location of the element or array on a patient's body such as on the skin surface or within a body cavity. The transducer element or transducer array associated with motors and control circuits comprises an assembly within a housing for fixation to or within a human body and is intended to be placed one time and then remotely manipulated in directions of rotation, twist, and linearly in first and second perpendicular directions within a plane parallel to the surface of the human body and remotely controlled to provide therapeutic or diagnostic treatment or imaging of an internal body region of interest under study. In one embodiment, the housing comprises at least one motor and one of a transducer element and a transducer array which is mounted to a rotor of the motor via an optional gear assembly for rotation, for example, in a range of 180 degrees so that multiple planes of imaging can be obtained, for example, of a heart or other body organ from the skin surface. The remotely manipulatable ultrasound transducer or transducer array assembly may comprise a wireless transceiver having a unique identifier for communication with one or more remote workstations, each having a unique identifier. Motors may provide linear, longitudinal axis movement, perpendicular movement to a longitudinal axis, rotation, twist and focus.Control information may comprise pulsing frequency, delay between elements, beamforming, time of day, direction, frequency, amplitude and the like to control one or more transducer elements or transducer arrays for therapeutic, diagnostic or imaging purposes.
Image Guided Catheters and Methods of Use
Patent # US8403859 B2 | 03/26/2013
An interventional medical device is provided that incorporates a forward-directed ultrasound imaging system integrated into a single device. The medical device can be in the form of sheaths, catheters, and interventional devices, particularly those suitable for minimally invasive procedures in the human or other mammalian body. The imaging system comprises one or more small ultrasound transducers that can be permanently integrated into the device or integrated into an interchangeable ultrasound transducer that can be inserted into and removed from the device to customize the device for a particular use. An ultrasound system can be provided in the device either alone or in combination with fiber optic imaging to provide a range of imaging and therapeutic capabilities of the device.
Image Guided Catheters and Methods of Use
Patent # US8403858 B2 | 03/26/2013
An interventional medical device that incorporates an imaging system may be minimally invasive and equipped with an anchoring portion at a proximal end for securing the device to a human body. A luer lock may be utilized at the proximal end, for example, for introducing a syringe. The medical device can be in the form of sheaths, catheters, and interventional devices, particularly those suitable for minimally invasive procedures in the pericardium. The imaging system comprises one or more ultrasound transducers and can be used to guide the device to a target area and to perform a procedure and/or provide access to a target area for performing a procedure via a plurality of lumen. In one embodiment, a micro-electro-mechanical system may be utilized to monitor pressure within a human body.
Remotely controlled implantable transducer and associated displays and controls
Patent # US8235903 B2 | 08/07/2012
An implantable, remotely controlled medical device that incorporates an imaging/therapy ultrasound system may be minimally invasive and equipped with an anchoring portion for securing the device within a human body. Transducers for imaging/therapy may be manipulated remotely using motors and/or selectively actuated to obtain different fields of view and stereoscopic imaging. The implantable medical device can be in the shape of a disc, double disc, sphere or pellet, for example, and may be implanted during open surgery using a manipulatable tool or using a minimally invasive image-guided sheath or catheter. The imaging system comprises one or more ultrasound transducers and can be used to provide therapy to or obtain ultrasound images of a target and surrounding volumes or focal points. The device may be controlled and report data by wired or wireless means and, if wireless, permanently worn inside the body as the patient follows their normal daily routine.
