Device for dissection of subcutaneous tissue

A system for dissection of subcutaneous tissue, comprising:

• a handpiece comprising a tissue engaging chamber defining a treatment region in which a target tissue comprising dermis, epidermis and subcutaneous tissue may be positioned, the tissue engaging chamber having a top comprising an adjustable lid,
• the handpiece further comprising a port configured to allow elevation of the target tissue into the chamber in the treatment region relative to surrounding tissue;
• a tissue cutting device having a proximal end and a distal end, the distal end of the tissue cutting device being positionable within the chamber and the treatment region for dissecting target tissue;
• the distal end of the tissue cutting device capable of movement within a predetermined shape within the treatment region;
• and
• the top of the tissue engaging chamber having an apposition surface and being configured to contact target tissue elevated within the chamber with the apposition surface, the adjustable lid configured to adjust a depth of the distal end of the tissue cutting device relative to the apposition surface.

A system for dissection of subcutaneous tissue, comprising:

• a handpiece comprising a tissue engaging chamber comprising an adjustable lid that at least partially defines a recessed area into which target tissue may be positioned, thereby defining a treatment region;
• a tissue cutting module comprising a housing and tissue cutting blade and configured to be operably coupled to the handpiece, the tissue cutting blade comprising a proximal end and a distal end;
• and
• the tissue engaging chamber being configured to elevate, relative to surrounding tissue, the target tissue into the recessed area of chamber and into contact with an apposition surface of the adjustable lid,
• wherein the adjustable lid allows adjustment of a depth of the tissue cutting device relative to the apposition surface,
• the distal end of the tissue cutting blade being positionable into the treatment region and capable of movement within a predetermined shape within the treatment region.

A system for dissection of subcutaneous tissue, comprising:

• a handpiece comprising a tissue engaging chamber defining a treatment region in which target tissue may be positioned, the tissue engaging chamber having a top comprising an adjustable lid configured to allow adjustable elevation of the target tissue into the chamber in the treatment region, relative to surrounding tissue;
• and
• a tissue cutting device comprising a tissue cutting blade having a proximal end and a distal end, the distal end of the tissue cutting blade positionable into the chamber and in the treatment region for dissecting the target tissue, wherein the distal end of the tissue cutting blade is capable of movement within a predetermined shape within the treatment region,
• wherein the adjustable lid comprises an apposition surface which the elevated target tissue contacts and wherein adjustment of the adjustable lid allows adjusting a depth of the distal end of the tissue cutting blade relative to the apposition surface.
