Abstract
Catheter systems and methods for implanting helical or dart-like implants into the myocardium or other body tissue. The catheter system includes a helix for fixing the distal end of the catheter to the myocardium, an implant held by the helix, mechanisms for driving the fixation helix into the myocardium, and mechanisms for driving the implant into the myocardium, removing the fixation helix and leaving the implant behind. The implant may be coated, filled, or made of a drug or drug eluting compound, or drug delivery matrix of any composition.
