Devices, systems, and methods for lead delivery
First Claim
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.

15. A system for delivering 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; a lead having a lead tip, the lead configured for at least partial insertion into the lead delivery channel and delivery to a heart tissue from the lead delivery channel outlet; 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. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A method of placing a lead in a tissue of a heart, the method comprising the steps of:
-
introducing into a blood vessel at least part of an elongated tube comprising a wall extending from a proximal end to a distal end; advancing the distal end of the elongated tube into a pericardial space surrounding a heart; positioning the distal end of the elongated tube within the pericardial space so that an outlet of a lead delivery channel of the elongated tube is positioned adjacent to a targeted heart tissue; inflating a balloon group positioned within a balloon chamber at or near the distal end of the elongated tube to anchor the elongated tube within the pericardial space, the balloon group comprising a central compliance balloon, a first lateral balloon, and a second lateral balloon, and the 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, 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; and delivering a lead through the lead delivery channel, out of the outlet, and into the targeted heart tissue. - View Dependent Claims (23, 24, 25)
