Implantable port placement system including low-scarring exterior

A subcutaneous access port system, comprising:

• a placement tool including a proximal handle and a port holder disposed distally;
• and
• an implantable access port releasably secured to the port holder, the implantable access port comprising:
• a housing including a base, a reservoir, and a stem aperture extending longitudinally through the base and communicating with the reservoir;
• a needle-penetrable septum covering the reservoir;
• and
• a body coupled to the housing over the needle-penetrable septum, the body comprising:
• a stem cover extending longitudinally from an outer surface of the body in a stem-wards direction, the port holder configured to engage the stem cover;
• a tunneling portion having a tunneling edge opposite of the stem cover designed to dissect tissue as the implantable access port is urged subcutaneously, a longitudinal cross-sectional shape of the tunneling portion defining a sigmoid profile having a concave hollow disposed between the tunneling edge and the reservoir;
• a skive extending linearly from a lateral outer-most point disposed stem-wards of a transverse central axis of the needle-penetrable septum, to the tunneling edge to define a tapered footprint;
• and
• wherein the port holder directly engages an inner surface of the stem cover to releasably secure the implantable access port to the placement tool.
