Embodiment Construction

[0057] The present disclosure relates to leads for stimulating anatomical structures. Although the carotid sinus is used as an example herein to demonstrate lead structures, it is understood that leads according to the present disclosure may be used to stimulate and / or monitor other anatomical structures. Such structures may include, but are not limited to, nerves, heart, spinal cord, brain, gastric and intestinal structures, pelvic structures, and diaphragm, among others. Leads according to the present disclosure may be used, for example, to stimulate the vagus nerve. In another example, leads according to the present disclosure may be used in epicardial applications. Other applications for leads are also contemplated within the scope of this disclosure.

Abstract

Various embodiments relate to implantable leads. The lead may include a lead body. At least two conductors may extend in the lead body, eg in respective lumens of the lead body. The leads may include at least two electrodes. Each electrode may be connected to a respective one of the at least two conductors. The paddle can be connected to the lead body. The paddle may include a longitudinal axis that divides the paddle into left and right sides. At least two electrodes may be partially embedded in the paddle. At least two electrodes may be aligned along the longitudinal axis. Each electrode may be asymmetric about the longitudinal axis.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Provisional Application No. 62 / 050,936, filed September 16, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to systems for stimulating anatomical structures. The present disclosure relates more particularly to paddle leads. Background technique [0004] Implantable pulse generators have been used to stimulate various anatomical structures such as the heart, brain, spinal cord and nerves, among other targets. Electrical energy is typically delivered from the implanted pulse generator to the target tissue via leads. Various types of leads have been developed for this purpose. In order to maintain the ability to deliver reliable chronic therapy, the lead needs to be secured within the body, eg, close to the target tissue. Lack of reliable anchoring may result in failure to stimulate target tissue and / or uninten...
