PERICARDIAL SPACE ACCESS

Abstract

A medical access system can comprise an inner needle assembly including an inner needle shaft configured to be slidably disposed at least partially within a delivery lumen of an outer needle assembly, the inner needle shaft comprising a narrower distal portion and a wider portion proximal of the narrower distal portion, and a transition segment between the narrower distal portion and the wider portion. A first delivery lumen within the inner needle shaft can extend from a proximal end of the inner needle shaft to a distal end opening at a distal end of the narrower distal portion, and a second delivery lumen within the inner needle shaft can extend from the proximal end to a distal opening associated with the transition segment.
