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.
Claims30
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.
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.
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.
