Methods and tools for accessing an anatomic space
First Claim
1. A method of accessing an anatomic space of a patient comprising:
- advancing a tubular access sleeve having a working lumen and a suction tool lumen through an opening in the patient to dispose a distal end of the sleeve adjacent tissue enclosing the anatomic space;
advancing a suction tool comprising a suction pad mounted to a support arm branching from a suction tool trunk and suction ports through the suction tool lumen to extend the suction ports distally from the sleeve, the suction pad comprising at least a portion of the suction ports; and
applying suction through the suction ports to grasp the tissue, whereby the anatomic space may be accessed through the working lumen.

Abstract
A tubular access sleeve and suction tool for accessing an anatomic surface or anatomic space and particularly the pericardium to access pericardial space and the epicardial surface of the heart in a minimally invasive manner are disclosed. A suction tool trunk extending through a suction tool lumen of the sleeve is coupled to suction pads at the ends elongated support arms. The suction pads can be retracted into a sleeve working lumen during advancement of the access sleeve through a passage and deployed from the tubular access sleeve lumen and disposed against the an outer tissue layer. Suction can be applied through suction tool lumens to suction ports of the suction pads that fix to the outer tissue layer so as to tension the outer tissue layer and/or pull the outer tissue layer away from an inner tissue layer so that the anatomic space can be accessed by instruments introduced through the working lumen to penetrate the outer tissue layer.
