/Flexible Torque Cable For Delivery Of Medical Devices
Abstract

The present disclosure describes delivery cables for delivering a medical device and methods of making and employing the same. In one embodiment, a delivery cable includes a flexible inner core, a proximal outer coil, and a distal outer coil. The proximal outer coil has a first rigidity. The distal outer coil surrounds at least a portion of a distal section of the flexible inner core and has a second rigidity less than the first rigidity thereby, thereby reducing bias placed on the medical device by the delivery cable during deployment of the medical device. Relative dimensions of an outer diameter of the distal outer coil and an inner diameter of a delivery sheath for deploying the delivery cable reduce snaking of the delivery cable within the delivery sheath.
