Abstract: Systems, methods, and interfaces are described herein for assisting in a user in configuring cardiac therapy. A projection of a phrenic nerve stimulation map may be projected on a graphical depiction of a portion of a patient's heart. The phrenic nerve stimulation map may indicate to a user the regions of the patient's heart that may have a likelihood of stimulating the patient's phrenic nerve.

Abstract: A method for localizing an internal body structure during an image-guided procedure that includes obtaining a three dimensional image of a body portion containing a targeted structure and selected reference structures; determining a set of landmark point coordinates for defining the location of each of the targeted and reference structures; computing triangulation parameters relating the location of the landmark points for the targeted structure and the reference structures; and, during an image-guided procedure, using the computed triangulation parameters to plot an estimated location of the targeted structure on an intra-operative image in which the reference structures have been identified.

Abstract: A heart model provides a simulative environment for lead implantation and affixation. In one embodiment, removable silicone plugs are provided at appropriate locations so that an inserted lead can be affixed to the plugs with a helical tip. A simulative venous structure is provided that has increased lubricity to facilitate the insertion and manipulation of the lead.
