Surface features for device retention are disclosed herein, e.g., for retaining an access port within a patient during a surgical procedure. The surface features can prevent ejection of the access port from a body of a patient. The surface features can be positioned along the access port and configured to glide along body tissues with minimal friction so as not to hinder travel of the access port in an insertion direction. After insertion of the access port, the surface features can engage with surrounding tissue to increase friction therebetween and to prevent ejection of the access port from the patient. Deployment of the surface features can occur due to friction with the surrounding tissue and/or via activation of the surface features to protrude from the access port. The surface features can include teeth, hooks, scales, fins, bristles, braids, and/or threads for engaging tissue. The surface features can be disengaged from the tissue to enable withdrawal of the access port without damaging the surrounding tissue.
