1. A surgical device, comprising:
- a one-piece biocompatible anchor configured to be implanted in a bone of a patient, the anchor not being bioabsorbable, the anchor having at least one bone-engaging surface feature on an exterior surface thereof that is configured to engage the bone and thereby secure the anchor in the bone, the anchor having an inner lumen extending therethrough configured to allow blood to flow into the inner lumen through a first open end of the inner lumen and out of the inner lumen through a second open end of the inner lumen when the anchor is implanted in the bone, and the anchor including an anti-coagulation agent, the at least one bone-engaging surface feature including a first flange, which extends radially outward from a proximal end of the anchor in which the first open end is formed, and a second flange, which extends radially outward from a distal end of the anchor in which the second open end is formed, wherein the anchor has a solid sidewall defining an entire length of the inner lumen through which the blood can flow in the anchor and that thereby limits blood that flows into the inner lumen through the first open end from exiting the inner lumen only through the first open end or the second open end.

Abstract
Various exemplary methods, systems, and devices for blood flow are provided. In general, an implant can be configured to be implanted in bone and to delay clotting of blood flowing from the bone. The implant can include an anti-coagulation agent to delay the clotting of the blood. The anti-coagulation agent can be a coating on the implant, can be natural to a material forming the implant, or can be impregnated into a material forming the implant. In an exemplary embodiment, the implant is implanted in a bone in a surgical procedure for securing a soft tissue to bone, such as a rotator cuff repair procedure or an anterior cruciate ligament (ACL) repair procedure.

8. A surgical device, comprising:
-
a biocompatible anchor configured to be implanted in a bone of a patient with an inner lumen extending through the anchor being open and free of occlusions, the inner lumen extending through the anchor such that blood can flow into the inner lumen through a first open end of the inner lumen and out of the inner lumen through a second open end of the inner lumen when the anchor is implanted in the bone, the anchor including an anti-coagulation agent; wherein the anchor includes a body and a flange integrally formed with the body, the flange extends radially outward from the body around an entire perimeter of the body at a fixed axial position along a longitudinal axis of the body, the body has a first maximum diameter, and the flange has a second maximum diameter that is greater than the first maximum diameter. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
