International Classification:

A61B 5/042
A61N 1/36
A61N 1/39
A61B 19/00

US Classification:

600374, 606129, 607 17, 607 5

Abstract:

Cardiac lead implantation systems, devices, and methods for lead implantation are disclosed. An illustrative cardiac lead implantation system comprises a mapping guidewire including one or more electrodes configured for sensing cardiac electrical activity, a signal analyzer including an analysis module configured for analyzing an electrocardiogram signal sensed by the mapping guidewire, and a user interface configured for monitoring one or more hemodynamic parameters within the body. The sensed electrical activity signal can be used by the analysis module to compute a timing interval associated with ventricular depolarization.

International Classification:

A61N 1/368

A61N 1/362
A61N 1/37
A61N 1/365

Abstract:

Systems and methods for selecting one or more sites at or within at least one heart chamber for cardiac stimulation are disclosed. The system can include a physiologic sensor circuit to sense physiologic signals at two or more candidate stimulation sites. The system can generate respective activation timing indicators corresponding to the two or more candidate stimulation sites, and detect MI indicators indicating the presence of, or spatial proximity of each of the two or more candidate stimulation sites to a MI tissue. The system can use the activation timing indicators and the MI indicators to select at least one target stimulation site or to determine an electrostimulation vector. The system can display the selected target stimulation site to a user, or deliver electrostimulation to the patient at the target stimulation site or according to the determined electrostimulation vector.
