A surgical implant () comprises a flexible, areal basic structure () having a first face and a second face and being provided with pores () extending from the first face to the second face. A barrier layer () having a first face and a second face is placed, with its second face, at the first face of the basic structure () and attached to the basic structure (). The barrier layer () is deformed into at least part of the pores () where it forms, in a respective pore (), a barrier region ().

Surgical implant and process of manufacturing thereof

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.

Surface features for device retention

A surgical implant () comprises a flexible basic structure () having a face and a plurality of resorbable film pieces () attached to the face of the basic structure (). Each film piece () comprises a plurality of solid protrusions () emerging from the respective film piece () is a direction away from the basic structure ().

Surgical implant

A surgical implant () comprises a basic structure () having a first face () and a resorbable film () attached to the first face () of the basic structure (). A plurality of solid protrusions () emerges from the film () in a direction away from the basic structure (). The protrusions () comprise a shape defined by a respective body and a respective head, the body emerging from the film () and terminating in the head, and the head projecting laterally with respect to the body.

A surgical implant () comprises a flexible basic structure () having a face and a plurality of resorbable film pieces () attached to the face of the basic structure (). Each film piece () comprises a plurality of solid protrusions () emerging from the respective film piece () in a direction away from the basic structure ().

A surgical implant () comprises an areal, flexible, porous basic structure () having a first face and a second face. At least one resorbable dyed film piece () is attached to the basic structure () and comprises a plurality of solid protrusions emerging from the dyed film piece () in a direction away from the basic structure (). The at least one dyed film piece () is arranged in a shape structure which is asymmetric ('E') in the area of the basic structure (). Optionally, the implant () further comprises an adhesion barrier sheet ().

A minimally invasive approach to adjusting the amount of support on an anatomical structure. The methods and apparatus described include the use of a tape for supporting an anatomical structure. Adjustment may be achieved by use of bulking agents applied either directly to the site or into a containment device located within proximity of the tape and such that it works in conjunction with the tape to support the anatomic structure. An alternative approach utilizes mechanical means for adjusting the effective length of the supporting arms of the tape used to support the anatomical structure.
