1. A method for recanalizing an occluded body vessel, comprising:
- advancing a longitudinal member through the occluded body vessel;
advancing a catheter over the longitudinal member, wherein the catheter comprises a proximal end, a distal end, and at least one lumen therebetween;
stabilizing the distal end of the catheter on a portion of an occlusion by applying suction through the lumen; and
penetrating the occlusion using the longitudinal member to recanalize the body vessel.

Abstract
Methods, devices, and systems for accessing and penetrating an anatomical structure using suction force and energy ablation or mechanical penetration. In one aspect, a catheter is stabilized on the occlusion, a longitudinal member is advanced to penetrate the occlusion and recanalize the body vessel. In another aspect, a catheter is stabilized on the pericardium, ablation energy is delivered through a longitudinal member to create an opening on the pericardium.

17. A system for recanalizing an occluded body vessel, comprising:
-
a catheter comprising a proximal end, a distal end, and a first lumen therebetween, wherein the catheter comprises an opening at the distal end configured to contact a portion of an occlusion; wherein the first lumen is configured to communicate a suction force applied at the proximal end to the opening at the distal end, thereby stabilizing the distal end of the catheter on the portion of the occlusion. - View Dependent Claims (18, 19, 20, 21, 22)

26. A method for accessing the heart, comprising:
-
advancing an access catheter through up to a portion of the pericardium; stabilizing a distal end of the access catheter on the portion of the pericardium; advancing a longitudinal member from the access catheter, wherein the longitudinal member comprises at least one energy delivery portion; delivering energy through the energy delivery portion of the longitudinal member to the portion of the pericardium, wherein an opening is created in the portion of the pericardium; and accessing the heart through the opening in the portion of the pericardium. - View Dependent Claims (27, 28, 29, 30)
