Abstract:
A catheter system for implantation of a helical drug delivery coil into the myocardium of the heart of a patient through the vasculature of the patient, said catheter system comprising:an outer sheath having a distal end adapted for percutaneous entry into the vasculature of the patient and navigation through the vasculature into the heart and a proximal end having a first handle, said outer sheath having a lumen extending through the sheath from the proximal end to the distal end thereof; an inner core disposed within the lumen of the outer sheath, said inner core being rotatable within the outer sheath and longitudinally slidable within the outer sheath, said inner core having a distal end adapted for percutaneous entry into the vasculature of the patient and navigation through the vasculature into the heart and a proximal end having a second handle; a first helix securely fixed to the distal end of the inner core, said helix sized and dimensioned to fit within the lumen of the outer sheath and be slidable and rotatable within the lumen of the outer sheath; a second helix nested within the first helix and thereby releasably secured to the inner core.
