Percutaneous skin access devices include a plurality of locked connecting units mounted to the exterior surface of an implantable medical object which, in position, is configured to penetrate the skin of a subject. The locked connecting units may be mounted directly onto the desired surface of the exterior of the device or may be held on a substrate sheet, which is mounted to the exterior surface of the device. In position, the locked connecting units engage with soft tissue which can include the skin to form a bio-junction layer which includes mechanical and bio-sealing connection between the device body and the soft tissue. The configuration at the bio-junction layer secures the medical object in location in the subject even for long-term indwelling applications in a manner, which inhibits soft tissue infection.The locked connecting units may be rigid or semi-rigid for longer-term indwelling applications, and semi-rigid and / or resilient for shorter term indwelling applications. The locked connecting units may take on the form of rings, hooks, or loops having aperture or gap width / length sizes of from about 0.2–4 mm. The rings, loops, or hooks may connect with any soft tissue including skin as well subcutaneous tissue. The rings, hooks, or loops may be released from the skin / tissue without requiring surgical cutting procedures.The locked connecting units may be configured as a semi-rigid mesh collar arranged about the primary body providing access to the subject such that it resides in the subject and engages with the skin (epidermal / dermal layer). The mesh collar can be described as a particular type of ring or loop structure as the mesh defines the gap provided in individual loop configurations. The mesh collar may be used alone, or in combination with the loops, rings, or hooks. A skin stop collar having increased rigidity may be disposed under the mesh collar.
