Abstract
A wireless electrostimulation system can comprise a wireless energy transmission source, and an implantable cardiovascular wireless electrostimulation node. A receiver circuit comprising an inductive antenna can be configured to capture magnetic energy to generate a tissue electrostimulation. A tissue electrostimulation circuit, coupled to the receiver circuit, can be configured to deliver energy captured by the receiver circuit as a tissue electrostimulation waveform. Delivery of tissue electrostimulation can be initiated by a therapy control unit.
Claims21
(canceled)
A wireless electrostimulation device, comprising:
- an implantable seed having a proximal end, a distal end, and a longitudinal axis extending from the proximal end to the distal end;
- a tissue attachment mechanism positioned proximate the distal end of the implantable seed, the tissue attachment mechanism configured to secure the implantable seed to cardiac tissue;
- a first electrostimulation electrode configured to contact cardiac tissue when the implantable seed is secured to cardiac tissue;
- a second electrostimulation electrode;
- wherein the first and second electrostimulation electrodes form an electrostimulation circuit to provide an electrical stimulus to cardiac tissue;
- and
- a retention pin located proximate the proximal end of the implantable seed, the retention pin oriented perpendicular to the longitudinal axis.
A wireless electrostimulation system, comprising:
- an implantable seed including:
- a housing having a proximal end, a distal end, and a longitudinal axis extending from the proximal end to the distal end;
- a tissue attachment mechanism positioned proximate the distal end of the housing, the tissue attachment mechanism configured to secure the implantable seed to cardiac tissue;
- and
- a retention pin located proximate the proximal end of the housing;
- an intravascular delivery system including:
- a delivery catheter having a distal end region surrounding the implantable seed during delivery of the implantable seed to cardiac tissue;
- and
- a retention feature configured to engage the retention pin while the implantable seed is positioned in the distal end region of the delivery catheter.
