LASER ABLATION/REMOVAL AND LASER INDUCED FORWARD TRANSFER OF BIOLOGICAL MATERIAL
A method for cell printing is disclosed. The method includes generating a receiver substrate, ablating or removing a portion of the receiver substrate via a first laser to expose a target layer, generating a donor substrate containing a back surface and a front surface, applying a coating of donor material to the front surface. The method further includes aligning the front surface of the donor substrate to be parallel to and facing the receiver substrate, wherein the donor material is disposed adjacent to the target layer, and irradiating the coating through the back surface of the donor substrate with one or more laser pulses produced by a second laser to transfer a portion of the donor material to the target layer. A system for cell printing is also disclosed.

ANTIMICROBIAL SILVER COMPLEX COATED SURFACE
The present invention relates to orthopedic implants, in particular to hip and knee prostheses, substantially involving metallic substrates with an antibacterial surface treatment consisting of silver immobilized in an organic linker and ligand via a multistep solution dipping and drying process. This treatment while being biocompatible is designed to inhibit bacterial growth and therefore combat periprosthetic infection which is one of the main causes of revision in hip and knee arthroplasty.

ANTI-INFLAMMATORY CANNULA
Various embodiments of the present invention include a cannula coated or compounded with a material to extend the wear time for a patient by reducing inflammation and therefore increasing the time that the cannula may remain inserted, thereby increasing the effectiveness of the drug delivered using the cannula. The material may include a hydrophilic material, an anti-microbial material, an anti-inflammatory material, anti-thrombogenic material, or a combination of any of these materials.
DEPOTS AND ENCASEMENT STRUCTURES FOR IMPLANTABLE DEVICES
Encasement structures and methods of customizing patient drug delivery profiles using an encasement structure are described herein. Encasement structures can be configured to receive an implantable medical device and physicians can implant the medical devices within the encasement structures. Encasement structures can include at least one sheet of a bioscaffold material and one or more depots. depots can be configured to release an active agent, such as an antibiotic, to the medical device within the encasement structure and/or the surrounding tissue. The depots can be insertable into or integrated with the at least one sheet of bioscaffold material.

METHODS, DEVICES, AND SYSTEMS FOR BLOOD FLOW
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.
