The present invention advantageously provides a molding device with conductive material for creating a catheter balloon with conductive elements, and methods and systems for manufacturing the catheter balloon with conductive elements. An exemplary method for coupling a plurality of conductive elements to an expandable element may include placing a first portion of a mold proximate a second portion of the mold to define a casting cavity. Conductive material may be deposited into the casting cavity. Polymeric material may be inserted into the casting cavity. The first portion of the mold may be secured to the second portion of the mold. The polymeric material may be expanded to place the polymeric material in contact with the conductive material.

Method for applying conductors to catheter based balloons

One or more non-transitory machine-readable media to store data and instructions executable by one or more processors. The instructions are programmed to analyze workflow data for a given phase of a plurality of phases of an ongoing electrophysiology (EP) workflow implemented using a first computing apparatus. The instructions can also determine at least one support event based on the analysis of the workflow data and send a request to at least one remote support specialist responsive to determining the at least one support event. The instructions further can establish a communication link between the first computing apparatus and a second computing apparatus, which is associated with a respective remote support specialist, and enable user interaction with and control of the machine-readable EP workflow instructions on the first computing apparatus responsive to a user input by the respective remote support specialist at the second computing apparatus.

Automated triggers for electrophysiology case support

In an example, a signal segment evaluator can be programmed to evaluate a morphology of at least one electrophysiological signal to identify a signal segment of interest. The morphology of the signal segment of interest can be indicative of an electrophysiological event of a patient during a respective time interval. A reconstruction engine can be programmed to reconstruct electrophysiological signals on a surface of interest within a body of the patient based on the electrophysiological signals measured from an outer surface of the patient and geometry data representing an anatomy of the patient. A map generator can be programmed to generate a map representing the reconstructed electrophysiological signals on the surface of interest for the respective time interval of the signal segment of interest. A target generator can be programmed to identify a target site within the patient's body based on the map for the electrophysiological event.

Systems and methods for electrocardiographic mapping and target site identification

In a described example, a method includes identifying, by a processor, negative deflections of at least one unipolar signal representing cardiac electrical activity on a surface of interest during a respective interval of the at least one signal. The method also includes determining, by a processor, an activation time for a last identified negative deflection in the respective interval. The method also includes detecting, by the processor, an instance of late activation based on comparing the activation time to a temporal threshold.

Late activation of cardiac signals

A compressible and expandable stent assembly for implantation in a body lumen such as a mitral valve, the stent assembly including at least one stent barrel that is shaped and sized so that it allows for normal operation of adjacent heart structures. One or more stent barrels can be included in the stent assembly, where one or more of the stent barrels can include a cylinder with a tapered edge.

Stented heart valve devices and methods for atrioventricular valve replacement

The present invention relates to a method, device, and system for improved mapping and/or ablation of a tissue. The device may generally include an elongate body and a distal assembly affixed to the elongate body that includes a treatment electrode having a conductive mapping region and a selectively conductive ablation region that is conductive of high-frequency current and substantially non-conductive of low-frequency current. Alternatively, the device may generally include a treatment electrode having a conductive mapping or ablation region and a region that is coated with an electrically insulated but thermally conductive layer.

Electrophysiology catheter design

A computer-implemented method includes storing location data for at least one invasive electrode that is movable within a patient's body. The method also includes storing electrophysiological measurement data representing the electrophysiological signals measured at the outer surface of a patient's body by body surface electrodes and within the patient's body by the at least one invasive electrode. The method also includes storing geometry data representing anatomy of the patient spatially, and locations of the respective body surface electrodes and the at least one invasive electrode in three-dimensional space. The geometry data for the at least one invasive electrode can vary based on movement of the at least one invasive electrode within the patient's body. The method also includes reconstructing electrophysiological signals on a surface of interest within the patient's body based on the electrophysiological measurement data and the geometry data.

Monitoring and analysis of invasive and non-invasive electrophysiological signals

A stented valve including a generally tubular stent structure that has a longitudinal axis, first and second opposite ends, a plurality of commissure support structures spaced from the first and second ends and extending generally parallel to the longitudinal axis, at least one structural wire positioned between each two adjacent commissure support structures, and at least one wing portion extending from two adjacent commissure support structures and toward one of the first and second ends of the stent structure. The stented valve further includes a valve structure attached within the generally tubular stent structure to the commissure support structures.

Stents for prosthetic heart valves

A device, system, and method for optically evaluating and treating or ablating tissue. Specifically, device, system, and method allow for the optical and/or electrical evaluation of tissue at the same location(s) at which ablation or treatment or ablation energy is delivered. This allows for a more accurate evaluation of lesion formation and tissue condition before, during, and/or after a treatment or ablation procedure. In one embodiment, a device for performing a medical procedure includes an elongate body including a proximal portion, a distal portion having a distal end, and a longitudinal axis, and a distal tip electrode at the elongate body distal end, the tip electrode being optically transparent and electrically conductive. The device may also include optical windows in the elongate body aligned with one or more transparent lateral electrodes for optically interrogating tissue and/or for delivering treatment or ablation energy to tissue.

Ablation catheter with dual optical-electrical stimulation and sensing

An example method includes establishing a communications link between an electrophysiology (EP) monitoring system and an implantable medical device (IMD). IMD electrical data is received at the monitoring system via the communications link. The IMD electrical data may be synchronized with EP measurement data to provide synchronized electrical data based on timing of a synchronization signal sensed by an IMD electrode and/or EP electrodes. The method also includes computing reconstructed electrical signals for locations on a surface of interest within the patient's body based on the synchronized electrical data and geometry data. The geometry data represents locations of the EP electrodes, a location of the IMD electrode within the patient's body and the surface of interest.

Using implantable medical devices to augment noninvasive cardiac mapping

A stented valve including a generally tubular stent structure that has a longitudinal axis, first and second opposite ends, a plurality of commissure support structures spaced from the first and second ends and extending generally parallel to the longitudinal axis, at least one structural wire positioned between each two adjacent commissure support structures, and at least one wing portion extending from two adjacent commissure support structures and toward one of the first and second ends of the stent structure. The stewed valve further includes a valve structure attached within the generally tubular stent structure to the commissure support structures.

Systems and methods for controllably variable fluid flow are disclosed that provide the ability to modify the effective cross-sectional area of the fluid delivery conduit available for fluid flow. Accordingly, selective control of these configurations allows fluid flow to be regulated as desired while the fluid delivery pressure remains the same. Additional configurations provided herein allow for the selective manipulation of a footprint or therapeutic pattern achievable with the medical device during a single procedure, negating the need for the removal and insertion of multiple devices to achieve the same variations in treatment geometry or characteristics.

Systems and methods for variable injection flow

Systems and methods for cardiac fast firing (e.g., atrial fast firing) detection perform frequency analysis on channels of collected cardiac waveform data and test the data for outlier frequency complex content that is of higher frequency than baseline frequency complex content associated with cardiac fibrillation (e.g., atrial fibrillation) or other arrhythmogenic activity. Anatomical regions from whence the cardiac fast firing originates can be displayed in real time on an epicardial surface map via a graphical display, aiding administration of therapy. Prior to such detection, QRST complex removal can be performed to ensure that ventricular activity does not infect the atrial fast firing analysis. A frequency-based method for QRST complex removal is also disclosed.
