Abstract: Cardiac tissue motion characteristics acquired by novel cardiac sensors are analyzed and processed for the derivation of physiological indices. The indices are output to a hand held local or remote volumetric haptic display and enable an operator to obtain motion related dynamic characteristics of cardiac tissues. The ability to tactually sense the motion of cardiac tissue and the affect on such motion from inserted cardiovascular instrumentation enhances the operator's performance of procedures including the positioning and placement of implanted catheters/sensors, extraction of permanently implanted leads and delivery of cardiovascular therapies. Optimal haptic rendering is achieved by using computational techniques to reconstruct the physically and perceptually relevant aspects of acquired signals and bridge the gap between the inserted catheter and operator's hand/catheter handle.

Abstract: A method of determining pacing therapy for an individual patient including determining representative electromechanical physiologic characteristics for a plurality of normal patients having a range of anatomical dimensions and developing a plurality of normal templates. Each template indicates the representative electromechanical physiologic characteristics of a group of normal patients having similar anatomical dimensions. The method can include measuring the anatomical dimensions of a dysfunctional patient, matching the dysfunctional patient with a template for normal patients having similar anatomical dimensions as the dysfunctional patient, determining the physiologic characteristics for the dysfunctional patient, determining indicated correction factors corresponding to any differences between the dysfunctional patient's physiologic characteristics and those of the matched template, and adjusting therapy delivery by any indicated correction factors to stimulate the patient in a pattern more closely matched to the physiologic characteristics of the matched template.

Abstract: A first lead provides therapeutic stimulation to the heart and includes a first mechanical sensor that measures physical contraction and relaxation of the heart. A controller induces delivery of therapeutic stimulation via the first lead. The controller receives signals from the first mechanical sensor indicative of the contraction and relaxation; develops a template signal that corresponds to the contraction and relaxation; and uses the template signal to modify the delivery of therapeutic stimulations. In another arrangement, a second lead, with a second mechanical sensor also provides signals to the controller indicative of contraction and relaxation. The first mechanical sensor is adapted to be positioned at the interventricular septal region of the heart, and the second mechanical sensor is adapted to be positioned in the lateral region of the left ventricle. The controller processes the signals from the first mechanical sensor and the second mechanical sensor to develop a dysynchrony index.

Abstract: A multi-channel implantable syncope monitor that monitors ECG data, myopotential data, EEG data, photoplethysmography (PPG) data, and position sensor data is used to capture physiologic data about a patient who is experiencing a syncopal event. The timing of the events within the simultaneously captured physiologic data can then be used to more accurately determine potential sources of origin of the syncopal event.

Abstract: An implantable therapy system including implantable stimulation and control components. The implantable components operate under a set of variable parameters that can be adjusted for improved performance for an individual patient. The implantable components are adapted to self-evaluate the patients physiologic performance and autonomously adjust an existing set of parameters to improve performance throughout an implantation period without requiring intervention of a clinician, for example with a physicians programmer. The implantable components can compare a patient's exhibited activity to a desired template of that activity to determine when adjustments are indicated. The template can be based on observations of one or more third parties exhibiting normal activity. The implantable components can adjust the operating parameters to improve synchrony of multiple heart chambers and/or to increase a peak contractility.

Abstract: A haptic system for a minimally invasive, hand-held surgical instrument and the system's various parts including a graphical user haptic interface, one or more haptic interfaces associated with a hand-held handle used to control a sensorized end-effector of the surgical instrument or inserted catheters, associated hardware, and an operating system. The system enables users to acquire, read, modify, store, write, and download sensor-acquired data in real time. The system can provide: an open, universally compatible platform capable of sensing or acquiring physiological signals/data in any format; processing of the sensor acquired data within an operating system; and outputting the processed signals to hardware which generates tangible sensations via one or more haptic interfaces. These tangible sensations can be modified by the user in real time as the system ensures the temporal relationship of sensed fiducial events are not altered or shifted relative to the generated and displayed haptic signals.
