Abstract: The present invention is generally related to methods and systems for preventing onset or worsening of RHF in patients with implanted ventricular assist devices. More particularly, the present invention relates to identifying patients at risk for RHF following implantation of a ventricular assist device based on pulmonary artery pressure measurement and/or trends and adjusting a pump operating parameter to prevent or reduce the onset or worsening of RHF in such patients, improve patient outcomes, or reduce mortality risks associated with VAD implantation. In particular, a pump operating parameter may be adjusted to reduce or minimize particularly high pressure loads on a patient’s heart or amount of time the patient is exposed to such high pressure loads following implantation.

Abstract: Systems and methods are provided for implanting an implantable cardiac monitor. An insertion system includes an implantable cardiac monitor (ICM). An insertion housing comprises a passage extending from a first end of the insertion housing to a second end of the insertion housing. The passage configured to receive the obturator and a receptacle in communication with the passage and an external environment. The receptacle configured to receive the ICM. An obturator is configured to move within the passage when the obturator is moved relative to the insertion housing. The obturator has a channel forming section at a distal end thereof and a motion limiter is provided on at least one of the shaft and the insertion housing.

Abstract: Controllers and methods for heart treatments are disclosed herein. The controller can include a communication module that can send and receive data from heart therapy devices. The controller can include memory including stored instruction. The controller can include a processor. The processor can receive a signal of an impending electrical treatment at a processor. The processor can determine a current operating parameter of a blood pump communicatingly coupled with the processor. The processor can determine an adjustment to the operating parameter of the blood pump to affect an impedance of heart tissue to be affected by the impending electrical treatment. The processor can control the blood pump according to the adjustment to the operating parameter of the blood pump.

Abstract: A method of pacing a His bundle of a patient heart using a stimulation system including a memory, a pulse generator, a stimulating electrode and at least one sensing electrode includes applying a plurality of impulses through the stimulating electrode to induce a plurality of responses from the patient heart. Each impulse of the plurality of impulses is delivered at a different impulse energy corresponding to a respective output setting of the stimulation system. The response characteristics for each of the plurality of responses are measured and each impulse is assigned a classification based on whether the respective response characteristics indicate capture of one or both of the His bundle and a ventricle of the patient heart. The output setting and classification for each impulse is then stored in the memory.
