Impedance tissue confirmation system

A delivery catheter for an implantable device, the delivery catheter comprising:

• a first conductive wire electrically connected to the implantable device or extending to a first electrode disposed adjacent to a first portion of the implantable device;
• a second conductive wire extending to a second electrode disposed adjacent to a second portion of the implantable device;
• and
• an electrical impedance sensor connected to the first conductive wire and the second conductive wire and configured to determine an electrical impedance between the first portion and the second portion of the implantable device to detect tissue capture between the first portion and the second portion of the implantable device.

A system comprising:

• a delivery catheter configured to be inserted into a puncture in a tissue wall, the delivery catheter comprising:
• a first conductive wire having a first electrode;
• and
• a second conductive wire having a second electrode;
• and
• a shunt device disposed on the delivery catheter, the shunt device comprising:
• a central flow tube extending from a first axial end to a second axial end;
• a first distal arm attached to the first axial end of the central flow tube;
• and
• a first proximal arm attached to the second axial end of the central flow tube, the first distal arm and the first proximal arm configured to capture the tissue wall therebetween;
• wherein the first electrode is disposed on the first distal arm, the first electrode separated from the shunt device by an insulating material;
• and
• wherein the second electrode is disposed adjacent to the first proximal arm, the second electrode separated from the first proximal arm by a spatial separation and/or an insulating material.
