Various types of incision control devices secure the periphery and / or adjacent tissue of a target incision site and maintain the size of the incision by a single wall of a blood vessel, organ or lumen within the body. This may reduce, among other things, unintentional trauma, dilation, contraction, or movement of the incision during the surgical procedure. They may also be used for the beneficial purpose of allowing immediate communication between lumens prior to complete formation of a permanent anastomosis. In some embodiments, magnetic compression stapling devices and / or other devices may be deployed through a channel of an incision control device, such as for deployment in a distal lumen.

Modular IOL removal systems and methods that cut an optic portion of an intraocular in a single motion such to facilitate removal of the optic portion from an eye through an incision, for example a corneal incision, without increasing the size of the corneal incision. Various cutting tools having one or more blades may be utilized. The cut intraocular lens may have one continuous cut or be cut into multiple smaller pieces. The single cutting step may apply balanced forces and torque to avoid damaging the surrounding eye anatomy, reducing the risk of trauma.

Among other things, this can reduce unintended trauma, dilation, contraction, or migration of the incision during a surgical procedure. They can also serve the beneficial purpose of allowing immediate communication between lumens prior to the complete creation of a permanent anastomosis. In some embodiments, magnetic compression anastomosis devices and / or other devices can be deployed through a channel in the incision control device, such as for deployment within the distal lumen.

A system for treating glaucoma is disclosed that includes a modular tube diverter implant having a flexible plate and a separable fluid drainage tube that are separately inserted and connected after insertion. The system includes a tube inserter featuring a delivery cannula having a needle tip-like distal end and a plunger having a pop-up rod configured to pierce the sclera and deliver the tube into the anterior chamber. A plate inserter, also including a cannula and a plunger, is configured to deploy the flexible plate in a compact form through the same small conjunctival incision, where the flexible plate is deployed to fit over the sclera. The connecting mechanism can easily connect the plate and the pipe through the notch. The system is specially designed for minimally invasive surgery, and therefore efficient deployment of the two components is achieved through the small-diameter cannula, and tissue damage and recovery time are reduced.
