Abstract: A device for cardiac surgery is disclosed. The device for cardiac surgery includes an aortic root retractor frame, an introducer, and one or more suture locking apparatuses. The device for cardiac surgery also includes an actuator for releasing the aortic root retractor frame, as well as a deployment mechanism for fully expanding the aortic root retractor frame. Multiple suture locking apparatuses used for releasable locking and unlocking of suture during a cardiac surgery procedure may be included in the device for cardiac surgery.

Abstract: A cannulation coupler has a primary branch comprising a retaining feature. The cannulation coupler also has a side inflow branch in communication with the primary branch. The cannulation coupler further has an outflow branch in communication with the primary branch and in communication with the side inflow branch. An adjustable cannulation assembly is also disclosed, having a cannulation coupler, an outer cannula, and an inner cannula. The cannulation coupler has 1) a primary branch comprising a retaining feature, 2) a side inflow branch in communication with the primary branch, and 3) an outflow branch in communication with the primary branch and in communication with the side inflow branch. The outer cannula is coupled to the primary branch. The inner cannula is coupled to the side inflow branch, wherein: 1) the inner cannula also passes through the primary branch; and 2) the inner cannula is coaxially slidable within the outer cannula.
