An apparatus for determining heart transplant rejection of a heart in a patient includes at least two electrodes adapted to be sewn into the heart that span the left ventricle. The apparatus includes a voltage generator adapted to be inserted in the patient which generates a voltage to the two electrodes and senses the resulting voltage from the two electrodes. A method for determining heart transplant rejection of a heart in a patient. A pacemaker for a patient (including bi-ventricular pacing and AICDs). The pacemaker includes an RV lead having four electrodes adapted to be inserted into the RV apex. The pacemaker includes a voltage generator which generates a voltage signal to the electrodes and senses the instantaneous voltage along the length of the RV and determines the real and imaginary components to remove the myocardial components of the septum and RV free wall to determine absolute RV blood volume. The pacemaker includes a battery connected to the voltage generator. The pacemaker includes a defibrillator connected to the battery. The pacemaker can also be a bi-ventricular pacemaker to restore RV and LV synchrony during contraction. A method for assisting a heart of a patient.

Method and apparatus for determining cardiac performance in a patient

An apparatus for monitoring a patient post operation having electrically conducting leads which are adapted to extend from inside the patient. The leads having electrodes adapted to communicate with a heart of the patient and apply electrical signals to the heart. The electrodes providing cardiac signals to the computer in response to the electrical signals so the computer can determine in real time at least one of heart volume, end diastolic heart volume, end systolic heart volume, stroke volume, change in heart volume, change in stroke volume, contractility, respiration rate or tidal volume regarding the patient.

Method and apparatus for monitoring a patient

An apparatus for a heart of a patient having a cardiac assist device adapted to be implanted into the patient to assist the heart with pumping blood. The apparatus has a sensor adapted to be implanted into the patient. The sensor in communication with the cardiac assist device and the heart which measures native volume of the heart. The apparatus has a first cardiac assist device and a second cardiac assist device tuned to maximize blood flow to the body of the patient, while resting the heart so the heart may recover function. Alternatively, the sensor monitors the heart based on admittance while the cardiac assist device. Alternatively, the sensor monitors the heart based on impedance.

Method and apparatus for assisting a heart

Exemplary embodiments of the present disclosure include apparatus and methods to classify the plaque tissue present in the coronary artery using intravascular optical coherence tomography (IVOCT) images.

Systems and methods for automated coronary plaque characterization and risk assessment using intravascular optical coherence tomography

Exemplary embodiments of the present disclosure include systems and methods for treatment of occlusions, including coronary artery chronic total occlusions.

Apparatus and methods for endometrial tissue identification

An apparatus for a heart of a patient having a cardiac assist device adapted to be implanted into the patient to assist the heart with pumping blood. The apparatus has a sensor adapted to be implanted into the patient. The sensor in communication with the cardiac assist device and the heart which measures native volume of the heart. Alternatively, the sensor monitors the heart based on admittance while the cardiac assist device. Alternatively, the sensor monitors the heart based on impedance.

An apparatus for measuring complex electrical admittance and/or complex electrical impedance in animal or human patients includes a first electrode and at least a second electrode which are adapted to be disposed in the patient. The apparatus includes a housing adapted to be disposed in the patient. The housing has disposed in it a stimulator in electrical communication with at least the first electrode to stimulate the first electrode with either current or voltage, a sensor in electrical communication with at least the second electrode to sense a response from the second electrode based on the stimulation of the first electrode, and a signal processor in electrical communication with the sensor to determine the complex electrical admittance or impedance of the patient.

Low power apparatus and method to measure complex electrical admittance or impedance

The present disclosure includes catheter systems and methods for treatment of occlusions, including coronary artery chronic total occlusions. The catheter system comprises a catheter coupled to a control system with a distal end inserted into a patient and proximal to a location within a blood vessel with an occlusion. The catheter comprises a flexible outer sheath surrounding a housing with a plurality of lumens to perform various functions to penetrate occlusions.
