摘要

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.

主权项

1. A catheter for delivery of a lead within a mammalian body, comprising:
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 integral to the elongated tube and defined within a relative side of the wall at or near the distal end of the elongated tube; and a balloon group positioned within the balloon chamber, the balloon group comprising a central compliance balloon, a first lateral balloon, and a second lateral balloon, the balloon group 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, wherein inflation of the balloon group causes the balloon group to protrude from the balloon chamber on the relative side of the wall of the elongated tube, wherein when inflated the balloon group does not surround the entire circumference of the elongated tube.
