Abstract
Devices, systems, and methods for lead delivery. In at least one exemplary embodiment of a catheter for delivering a lead within a mammalian body of the present disclosure, the catheter comprises an elongated tube comprising a wall extending from a proximal end to a distal end, a lead delivery channel within the elongated tube, the lead delivery channel defining an outlet for delivering a lead, a balloon chamber positioned at or near the distal end of the elongated tube, and at least one balloon positioned within the balloon chamber, the at least one balloon capable of inflation to reversibly anchor the elongated tube within a mammalian body when at least a portion of the elongated tube is positioned therein.
