Abstract
A magnetically topped catheter is used to tunnel into the myocardium for cardiac treatment.
Claims11
A method for myocardial treatment comprising the steps of:
- navigating a catheter to a treatment site;
- displacing the catheter into the tissue at the treatment site
- directing the tip of the catheter with magnetic fields applied from outside the body;
- advancing the tip through tissue causing mechanical disruption of tissue forming a tunnel in the tissue at the treatment site.
1 more element
A catheter comprising:
- a catheter body having a proximal end and a distal end;
- a tunneling structure located at the distal end of the catheter body;
- a magnetic element located proximate the distal tip of said catheter body;
- for guiding the catheter tip in response to external magnetic fields and gradients.
1 more element
A method of treating the heart comprising the steps of:
- navigating a catheter to the myocardium;
- entering the myocardium assisted by the application of externally generated magnetic fields and gradients to create a treatment site;
- delivering a magnetically bound drug to the treatment site;
- withdrawing the catheter while retaining the drug of the site with a magnetic field or gradient.
1 more element
A method of treating the heart comprising:
- navigating a catheter having a magnetic tip to the myocardium using externally applied magnetic fields or gradients to direct the tip;
- advancing the catheter into the myocardium at a singular treatment site;
- injecting a drug through a lumen in the catheter into the myocardium at the treatment site;
- withdrawing the catheter from the treatment site.
