Abstract
An introducer cannula for use in crossing pleural layers includes an elongate tubular member and a pleural access liner. The elongate tubular member has a proximal end, a distal end, and a side wall that longitudinally extends between the proximal end and the distal end. The side wall has an outer surface and an inner surface, wherein the inner surface defines a lumen. The pleural access liner is made of a swellable and bioabsorbable material that swells when hydrated. The pleural access liner has a shape of an elongate tube and the pleural access liner has an elongate opening that surrounds an outer surface portion of the outer surface of the elongate tubular member.

An introducer cannula for use in crossing pleural layers, comprising:
- an elongate tubular member having a proximal end, a distal end, and a side wall that longitudinally extends between the proximal end and the distal end, the side wall having an outer surface and an inner surface, wherein the inner surface defines a lumen,
- wherein the outer surface of the side wall of the elongate tubular member has a first outer surface portion having a first diameter and a second outer surface portion that separates the first outer surface portion into two sections, the second outer surface portion having a second diameter that is less than the first diameter, wherein the second outer surface portion of the side wall defines an elongate exterior recess that extends around the elongate tubular member between the two sections of the first outer surface portion of the tubular member;
- and
- a pleural access liner made of a swellable and bioabsorbable material that swells when hydrated, wherein the pleural access liner has a shape of an elongate tube and the pleural access liner surrounds an outer surface portion of the outer surface of the elongate tubular member, wherein the pleural access liner resides in and surrounds the elongate exterior recess of the side wall of the elongate tubular member.

- and
- a bioabsorbable member positioned in the elongate exterior recess of the side wall of the tubular member, the bioabsorbable member constructed of a material that swells upon contact with a fluid.
