Atraumatic medical device anchoring and delivery system with enhanced anchoring

A system for providing medical treatment to a patient, the system comprising:

• a structure for attachment to the patient, the structure having a generally rectangular shape and having extending therefrom a plurality of arms, each arm including a proximal end coupled to the generally rectangular shape of the structure and a distal end;
• an aperture located near the distal end of each arm, each aperture including a key for accepting the insertion of a retractable barb and for establishing a desired alignment of the structure with respect to the retractable barb;
• and
• a plurality of apertures located near a perimeter portion of the generally rectangular shape of the structure, each aperture of the plurality of apertures including a key for accepting the insertion of a retractable barb and for establishing a desired alignment of the structure with respect to the retractable barb.

A retractable barb for attaching a portion of a medical device to a patient, the retractable barb comprising:

• a pair of movable arms, each movable arm having a first and a second end, the first ends of the pair of movable arms being coupled together;
• a base member having a first end and a second end, each end of which is coupled in proximity to a second end of a respective one of the pair of movable arms;
• and
• wherein the pair of movable arms and the base member form a triangular structure having an outer surface and an inner surface, the inner surface forming an aperture between the pair of movable arms and the base member for tissue growth.
