A delivery guidewire for navigating a catheter in the heart to deliver a valve prosthesis. The delivery guidewire comprising an elongated core, an outer sleeve disposed on the elongated core, and a coil disposed on a distal portion of the elongated core. The delivery guidewire having a first section having a generally uniform diameter and a second section having a tapering section. A distal portion of the second section of the delivery guidewire comprises a pigtail shape atraumatic tip which can remain in the left ventricle.

A method for providing a treatment recommendation to a physician for treating a patient is disclosed. The method comprises determining, from a processor in communication with a patient data repository, a first treatment recommendation based on a combination of selected patient demographics from the patient data repository applicable to the patient, and operational parameters of a plurality of ventricular assist devices (VADs) suitable for treating the patient, the first treatment recommendation having a first survival rate and comprising the use of a first VAD. The method then obtains a first signal from using the first VAD on the patient. The method then determines a second treatment recommendation based on the first signal and the first treatment recommendation, the second treatment recommendation having a second survival rate. The method then provides the second treatment recommendation to the physician if the second survival rate is higher than the first survival rate.

A quantum cardiac electrophysiology device comprising an array of consumable half-ferromagnetic active electrodes connected to an array of semiconductor of half-ferromagnetic selector switches over an array of half-ferromagnetic resistors to a neutral charges out of the heart, by casting and/or inking the arrhythmic substrate of an arrhythmia by the electrophysiology quantum entan- glement of said arrhythmic substrate.

A quantum spin liquid (QSL) electrophysiology device comprising a spontaneous and an induced quantum arrhythmia vacuum states, switchable between them through at least one entangled measurement of one negative differential resistance.

The present technology is generally directed to interatrial shunting systems and associated devices and methods. For example, a system configured in accordance with embodiments of the present technology can include a shunting element implantable into a patient at or adjacent a septal wall. The shunting element can have a lumen that fluidly connects a left atrium and a right atrium of the patient to facilitate blood flow therebetween when the shunting element is implanted. In some embodiments, the system further includes a flow control element to selectively control blood flow between the left atrium and the right atrium.

A catheter includes a tip electrode with a shell and a support member to provide a plenum chamber. The plug is formed with a U-shaped passage for a safety line to wrap around and secure the support member (with the shell affixed thereto) to the catheter. Additional passages are formed in the plug to accommodate components such as irrigation tubing, lead wire and thermocouple wire pair. A method of manufacture provides distal installation and/or anchoring of the safety line, lead wire and thermocouple wire pair in the support member prior to sealing the support member and mounting the shell.

The present invention generally relates to heart treatment systems. In some aspects, methods and systems are provided for facilitating communication between implanted devices. For example, an implantable cardiac rhythm management device may be configured to communicate with an implantable blood pump. The implantable cardiac rhythm management device may deliver heart stimulation rate information in addition to information associated with any detected abnormalities in heart function. In response, the pump may be configured to adjust pumping by the pump to better accommodate a patient's particular needs.

The present technology relates to interatrial shunting systems and methods. In some embodiments, the present technology includes interatrial shunting systems that include a shunting element having a lumen extending therethrough that is configured to fluidly couple the left atrium and the right atrium when the shunting element is implanted in a patient. The system can also include an energy receiving component for receiving energy from an energy source positioned external to the body, an energy storage component for storing the received energy, and/or a flow control mechanism for adjusting a geometry of the lumen.

A control device for a heart pump, comprising a device for establishing the end-diastolic filling pressure in a ventricle and a device for associating a delivery rate of the pump, in particular a pump speed or an electric pump capacity, with the established end-diastolic filling pressure. By taking into account the end-diastolic filling pressure, a robust operating option of the heart pump, similar to the physio-logical control, is created.

Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.
