Implantable interface device

A method for implanting an interface device for transcutaneous access in a subject, the method comprising the steps of:

• a. preparing tissue at an implant site of the subject;
• b. placing the interface device, having a porous tissue integration layer and a crowning element, at the prepared implant site, with the porous tissue integration layer in contact with the prepared tissue, the interface device including:
• i. a tissue integration layer having a porous structure forming a scaffold into which tissue integrates to anchor the device when implanted,
• ii. a crowning element attached to an upper surface of the tissue integration layer and configured such that once implanted, there is epidermal attachment to part of the crowning element, and part of the crowning element extends though the epidermis and is accessible from outside the body, and
• iii. a removable seal capable of applying a negative pressure overlaying the part of the crowning element accessible from outside the subject's body,
• wherein the porous structure of tissue integration layer is interconnected for tissue ingress during implantation, and wherein the tissue integration layer is sized and shaped to provide a foundation that supports the crowning element such that when implanted, the tissue integration layer is entirely anchored beneath the epidermis;
• and
• c. applying negative pressure to the device to enhance tissue integration into the pores of the tissue integration layer.
