Applicator and tissue interface module for dermatological device
First Claim
1. A tissue interface module for use with an applicator in a microwave-based tissue modification system, the tissue interface module comprisingan applicator chamber on a proximal side of the tissue interface module, the applicator chamber comprising:
- an opening adapted to receive the applicator;
an attachment mechanism positioned in the applicator chamber and adapted to attach the tissue interface module to the applicator;
a sealing member positioned at a proximal side of the applicator chamber;
a vacuum interface positioned at a proximal side of the applicator chamber and adapted to receive a vacuum inlet positioned on a distal end of the applicator;
a tissue acquisition chamber on a distal side of the tissue interface module, the tissue acquisition chamber comprising a tissue acquisition opening on a distal side of the tissue interface module;
a flexible bio-barrier positioned between, and in fluid communication with, the applicator chamber and the tissue acquisition chamber, the flexible bio-barrier being substantially impermeable to air or fluids;
an airflow pathway within the tissue interface module, the airflow pathway connecting the applicator chamber and the tissue acquisition chamber;
a filter disposed in the airflow pathway connecting the applicator chamber and the tissue acquisition chamber, the filter being permeable to air and substantially impermeable to fluids.

Abstract
An tissue interface module has an applicator chamber on a proximal side of the tissue interface module and a tissue acquisition chamber on a distal side of the tissue interface module. The applicator chamber may include: an opening adapted to receive the applicator; an attachment mechanism positioned in the applicator chamber and adapted to attach the tissue interface module to the applicator; a sealing member positioned at a proximal side of the applicator chamber; and a vacuum interface positioned at a proximal side of the applicator chamber and adapted to receive a vacuum inlet positioned on a distal end of the applicator. The invention also includes corresponding methods.
