Abstract
A therapeutic agent is delivered to heart tissue in a body. The therapeutic agent is introduced to a first side of the heart tissue. An electrode is percutaneously located on a second side of the heart tissue. The electrode is energized to induce migration of the therapeutic agent into the heart tissue.
Claims24
A method of delivering a therapeutic agent to heart tissue in a body, comprising:
- introducing the therapeutic agent to a first side of the heart tissue;
- percutaneously locating an electrode on a second side of the heart tissue;
- and
- energizing the electrode to induce migration of the therapeutic agent into the heart tissue.
1 more element
An apparatus for delivering a therapeutic agent to heart tissue in a body, the apparatus comprising:
- an elongate member having a proximal end and a distal end;
- an electrode coupled to the distal end of the elongate member;
- and
- wherein the elongate member is configured to be introduced and advanced through vasculature in the body and positioned in a heart chamber, the electrode being configured to be energized to induce migration of the therapeutic agent, injected proximate the heart tissue, into the heart tissue.
1 more element
A method of delivering a therapeutic agent to heart tissue in a heart of a body having vasculature, the method comprising:
- introducing ionic therapeutic agent on a first side of the heart tissue;
- and
- with a field generator, at least a portion of which is located within the body on a second side of the heart tissue, generating a field inducing migration of the therapeutic agent into the heart tissue.
