2026
The Foldable Capsular Vitreous Body (FCVB) is an intraocular implant that encapsulates silicone oil within a flexible capsule to reduce silicone oil-related complications. This protocol describes the surgical implantation of the FCVB via scleral incision for the treatment of complex retinal detachment and ocular trauma.

Middle cerebral artery (MCA) ligation is a technique to study focal cerebral ischemia in animal models. In this method, the middle cerebral artery is exposed by craniotomy and ligated by cauterization. This method gives highly reproducible infarct volumes and increased post-operative survival rates compared to other methods available.

We describe a highly reproducible method for the permanent occlusion of a rodent major cerebral blood vessel. This technique can be accomplished with very little peripheral damage, minimal blood loss, a high rate of long-term survival, and consistent infarct volume commensurate with the human clinical population.

Various murine models of middle cerebral artery occlusion (MCAO) are widely used in experimental brain research. Here, we demonstrate the model of transcranial permanent distal MCAO which produces consistent cortical infarction of a size corresponding to damage imposed by the majority of human ischemic strokes.

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals1 dictates that rodent survival surgery be performed aseptically. Aseptic technique utilizes specific practices that minimize the contamination of the surgical site, including patient preparation, surgeon preparation, sterilization of instruments and other supplies, and the use of a clean and controlled environment. Presurgical planning,...
FAQs
Biocompatibility determines how well the implanted device or material is tolerated by surrounding tissues over time. Poor compatibility can contribute to tissue reactions and compromise the intended therapeutic or functional support. Selecting materials suited to the anatomical site therefore works alongside precise placement and postoperative monitoring to promote stable healing and reduce the likelihood of adverse local responses.
Healing may stabilize an implant through two different tissue responses described in implantation surgery. Tissue integration allows surrounding tissue to become associated with the implant, whereas a fibrous capsule forms a layer around it. Either response can contribute to long-term positioning, but the resulting stability depends on the implant, its location, and the quality of surgical placement.
Device selection must match the intended therapeutic or functional purpose and the anatomical site where placement will occur. Surgeons also need to account for biocompatibility, accurate positioning, and a method of securing the implant. These factors work together: an appropriate device may still perform poorly if placement is imprecise or fixation does not support healing.
A controlled operative pathway and sterile conditions help limit contamination while the surgeon reaches the intended anatomical site. The implant is then positioned and secured without disrupting the planned placement. This procedural control is important because infection is a recognized complication of long-term implantation, and infection can threaten healing, implant stability, and the desired therapeutic result.
The procedure centers on creating a controlled surgical route, preparing access to the intended anatomical location, positioning the selected device or material, and securing it for long-term support. Sterile technique is maintained throughout the operation. Subsequent healing may reinforce stability through tissue integration or fibrous encapsulation, so the operative result must be assessed over time.
This approach is relevant when a patient needs durable structural replacement, restoration of bodily function, or a delivery or support system that must remain in place. The specific choice depends on the intended clinical purpose and the suitability of the device for long-term placement. Its value lies in providing continuing support after the operative pathway has closed.
Follow-up should focus on infection, displacement, and tissue reactions, along with whether the implant remains stable and continues to provide its intended support. These complications can arise despite technically careful placement. Monitoring helps identify problems that may affect healing or function and supports evaluation of whether the selected device and implantation site remain appropriate over time.
