Abstract
An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple penetrators advanced through supported guide tubes which expand around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, nerve sensing, nerve stimulation, or ablation by application of energy. The catheter can include a proximal handle for the advancement of guide tubes and penetrators.
Claims21
1-20. (canceled)
A catheter comprising:
- a catheter body;
- a first guide tube having a first lumen and a second guide tube having a second lumen, wherein the first guide tube and the second guide tube are configured to rest against a wall of a target vessel;
- a first penetrator and a second penetrator configured to penetrate the wall of the target vessel, the first penetrator located coaxially inside of the first lumen of the first guide tube, and the second penetrator located coaxially inside of the second lumen of the second guide tube;
- and
- a proximal handle comprising a movement mechanism configured to allow relative movement of the first guide tube and the second guide tube with respect to the catheter body by advancing the movement mechanism longitudinally along the catheter body between a first catheter state icon and a catheter state icon, the movement mechanism further configured to allow relative movement of the first penetrator and the second penetrator relative to the first guide tube and the second guide tube, respectively, by advancing the movement mechanism longitudinally along the catheter body between the second catheter state icon and a third catheter state icon.
A catheter comprising:
- a catheter body;
- a first guide tube having a first lumen and a second guide tube having a second lumen, wherein the first guide tube and the second guide tube are configured to rest against a wall of a target vessel;
- a first penetrator and a second penetrator configured to penetrate the wall of the target vessel, the first penetrator located coaxially inside of the first lumen of the first guide tube, and the second penetrator located coaxially inside of the second lumen of the second guide tube;
- and
- a proximal handle comprising a movement mechanism configured to allow simultaneous outward movement of the first guide tube and the second guide tube with respect to the catheter body by advancing the movement mechanism longitudinally along the catheter body between a first catheter state icon and a second catheter state icon, the movement mechanism further configured to allow simultaneous penetration of the first penetrator and the second penetrator beyond the first guide tube and the second guide tube, respectively, by advancing the movement mechanism longitudinally along the catheter body between the second catheter state icon and a third catheter state icon.
