Patent ID: 8874237

Claim:
A system for implanting an implantable element proximate to the His bundle, wherein the implantable element is configured for at least one of therapy delivery or sensing proximate to the His bundle, and wherein the system comprises: a delivery catheter comprising: a catheter body comprising a proximal end, a distal end and a perimeter surface extending along a length of the catheter body between the proximal end and the distal end, wherein the catheter body comprises a longitudinal axis and defines a delivery lumen extending along the longitudinal axis within the catheter body; a side port defined in the perimeter surface, orthogonal to the longitudinal axis, and proximate the distal end and in communication with the delivery lumen, wherein the implantable element is sized for delivery through the delivery lumen and out of the side port; a first electrode; and a second electrode, wherein each of the first and second electrodes is adjacent to and spaced from the side port; and an external device, wherein the delivery catheter comprises a connector at or near the proximal end to electrically couple the first and second electrodes to the external device, wherein the first and second electrodes are configured to obtain an electrocardiogram of the patient, wherein the external device is configured to receive the electrocardiogram from the first and second electrodes, analyze the electrocardiogram, and detect a signature waveform of the His bundle based on the analysis of the electrocardiogram, for implanting the implantable element at a location based on the detection of the signature waveform of the His bundle, and wherein the signature waveform comprises at least one of the atrial P-wave, ventricular QRS signature, and a His spike between the P-wave and QRS signature.
