Clinical Trial Summary

The VisONE HF pilot is a feasibility pilot for evaluating the benefits and risks of chronically delivering Asymptomatic Diaphragmatic Stimulation in medical refractory heart failure patients using the VisONE™ implantable system for 12 months.


Description:

This 12 month study is intended to validate the early benefits observed with Asymptomatic Diaphragmatic Stimulation (ADS) as a primary form of heart failure therapy with low rates and severity of adverse effects. Medical refractory symptomatic heart failure patients with reduced ejection fraction and no evidence of arrhythmias or ventricular dysynchrony will undergo laparoscopic implantation of the VisONE™ implantable system comprised of a pulse generator and two leads, programmed to deliver cardiac-gaited diaphragmatic stimulation pulses at asymptomatic outputs. Patients will be followed in pre-specified durations of 1,3,6 and 12-months using a series of evaluations of hemodynamic, echocardiographic, heart failure status, diaphragmatic function, implanted system data and standard safety measures including adverse events, for comparison with their baseline values. The results are intended to be used for designing a subsequent larger study for performing statistical power calculations.

Outcome

Type Measure Description Time frame Safety issue
Other Clinical composite of heart failure and cardiac function The following outcomes will be analyzed determine the potential therapeutic impact on clinical heart failure management
NT Pro-BNP blood levels to assess heart failure status
Improvements to cardiac output, stroke volume or left ventricular filling
Improvements to left ventricular volumes or ejection fraction
Improvements to heart failure status, 6 minute hall walk, or assessment by heart failure questionnaire
after 0, 1, 3, 6 and 12 months of therapy
Primary Freedom from serious complications or adverse events during procedural recovery and acute therapy The following serious complications and adverse events will be analyzed for their rate and severity and compared to other implantable device systems
Excessive procedural or implanted system morbidity
Procedural or implanted system events resulting in unscheduled patient hospitalizations and surgical intervention
Incidences resulting in physician choice to permanently discontinue therapy
after 3 months of therapy
Secondary Freedom from complications or adverse events during chronic therapy The following adverse events will be analyzed for their rate and severity and compared to other implantable device systems
Procedural or implanted system events resulting in adverse patient symptoms
Degradation of respiratory function by spirometer measures associated with procedure or implanted system
Adverse events due to procedural or implanted system complications correctable by non re-operative means including system reprogramming or other readjustments
after 3 and 12 months of therapy
Secondary Freedom from serious complications or adverse events during chronic therapy The following serious complications and adverse events will be analyzed for their rate and severity and compared to other implantable device systems
Excessive procedural or implanted system morbidity
Procedural or implanted system events resulting in unscheduled patient hospitalizations and surgical intervention
Incidences resulting in physician choice to permanently discontinue therapy
after 12 months of therapy
