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.
