Abstract
A cardiac lead includes a half-domed or semi-spherical shaped distal assembly and an active fixation mechanism. The half-domed or semi-spherical shape provides directionality as to whether a flat side of the lead is facing the myocardial tissue and therefore the active fixation mechanism can be deployed safely into the myocardial tissue.
Claims20
A cardiac lead, comprising:
- a cylindrical body having a proximal assembly and a distal assembly, said distal assembly comprising:
- a distal end having a half-domed or semi-spherical shape;
- an active fixation mechanism housed in the distal assembly and that is deployable and retractable from a flat surface of the distal assembly;
- and
- a steroid reservoir.
2 more elements
A cardiac lead, comprising:
- a cylindrical body having a proximal assembly and a distal assembly, said distal assembly comprising:
- a distal end having a geometric shape to provide lead directionality to heart tissue and to provide placement of means for fixing the distal end to the heart tissue, said means for fixing being deployable and retractable from a flat surface of the distal assembly.
