Splittable sheath

Abstract

A splittable sheath for an implantable medical device can include a jacket having an outer diameter and an inner diameter. A lumen can be defined by the inner diameter and extended from a proximal end to a distal end of the jacket. An electrode can be located at the distal end of the jacket. A signal wire can be disposed within the jacket and can be electrically coupled to the electrode. A rail can be configured to shield the signal wire from a cut path of a sheath splitter. In some examples, the sheath can further include a second rail. For instance, the signal wire can be located between a first rail and a second rail along the length of the sheath. The cut path can be located between the first rail and the second rail on a radially opposing side of the sheath from the signal wire.

Description

technical field [0001] The present disclosure relates to a detachable sheath for navigating placement of an implantable device into a patient. Background technique [0002] Cardiac rhythm management systems are used to electrically stimulate a patient's heart to treat various arrhythmias. The current standard of care is right ventricular pacing via myocardial stimulation. In this technique, pacemaker leads are placed at the apex of the right ventricle and the atrioventricular node, coronary sinus, or left ventricle, and the pacemaker sends electrical impulses to these areas of the heart. While effective, this technique results in abnormal electrical activation sequences that lead to mechanical ventricular dyssynchrony, increasing the risk of heart failure, atrial fibrillation, and overall mortality. [0003] An alternative approach has been proposed in which electrode leads are placed in the bundle of His located in the septal wall of the right atrium or also in the intera...
