This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device system for treating a heart includes a control system including a display unit. Further, the display unit is configured to display a first visual representation of a first medical device disposed in a first anatomical location, a second visual representation of a second medical device disposed in a second anatomical location, a third visual representation of a first physiological parameter, wherein the first physiological parameter is measured by a first sensor disposed at a first location proximate the first medical device and a fourth visual representation of a second physiological parameter, wherein the second physiological parameter is measured by a second sensor disposed at a second sensor location proximate the second medical device.

Disclosed are techniques for delaying initiation of coagulation and suppressing fibrin formation. The disclosed techniques may include providing a percutaneous blood pump that may include a metal or ceramic surface (such as a surface of a shaft, bearing, rotor, stator, etc.) that has been modified with a bifunctional modifier. The modified surface may be within a motor section and/or pump section of the blood pump. The modified surface may be configured to interact with blood. When blood is allowed to interact with the modified surface, a desirable microenvironment may be formed. The bifunctional modifier may be a functionalized aminosilane, a functionalized aminosiloxane, and/or a functionalized silanetriol. The blood pump may be configured to have a purge fluid pass through at least a portion of the motor section and/or the pump section. The purge fluid may be free of anticoagulants.
