An apparatus is disclosed for differentially treating a medical device. One portion of the device is treated with a first fluid and a separate portion is treated with a second fluid. The second fluid generally is substantially different from the first fluid. The first fluid can be contacted with an flow region of the medical device. The apparatus can include a conduit system, where fluid flowing through the conduit system flows through the flow region. Sheet material can be treated differentially on the opposite surfaces of the sheet. The medical device can include vascular tissue.

A method is disclosed for processing tissue by inoculating the tissue with a solution having microorganisms, where the microorganisms are selected to produce compounds that process the tissue. The tissue is incubated with the inoculated microorganisms under conditions that are effective for processing the tissue by the chemicals produced by the microorganisms. The tissue maybe subsequently treated to substantially remove or inactivate the microorganisms.

A splint assembly for placement transverse a heart chamber to reduce the heart chamber radius and improve cardiac function has a tension member formed of a braided cable with a covering. A fixed anchor assembly is attached to one end of the tension member and a leader for penetrating a heart wall and guiding the tension member through the heart is attached to the other end. An adjustable anchor assembly can be secured onto the tension member opposite to the side on which the fixed pad assembly is attached. The adjustable anchor assembly can be positioned along the tension member so as to adjust the length of the tension member extending between the fixed and adjustable anchor assemblies. The pad assemblies engage with the outside of the heart wall to hold the tension member in place transverse the heart chamber. A probe and marker delivery device is used to identify locations on the heart wall to place the splint assembly such that it will not interfere with internal heart structures. The device delivers a marker to these locations on the heart wall for both visual and tactile identification during implantation of the splint assembly in the heart.

A prosthetic stentless aortic tissue valve includes a substantially annular valve body having a leaflet carried therein for occluding blood flow therethrough. A root extends generally coaxially from the valve body. Visual marking are provided on the root and act as a sculpting guide for a surgeon during implantation of the prosthetic heart valve to sculpt portions of sinus areas of the root.

A method for placing a splint assembly transverse a heart chamber includes providing an elongate member having a first end and a second end and a deployable heart-engaging assembly connected to at least the first end. The method includes advancing the elongate member through vasculature structure and into the heart chamber such that the first end of the elongate member extends through a first location of a wall surrounding the heart chamber and the second end extends through a second location of the heart chamber wall substantially opposite the first location. A deployable heart-engaging assembly is deployed such that it engages with a first exterior surface portion of the heart chamber wall adjacent the first location. The elongate member is secured with respect to the heart with a second heart-engaging assembly connected to the second end. The second heart-engaging assembly engages with a second exterior surface portion of the heart chamber wall adjacent the second location.

Devices and related methods for treating heart conditions, including, for example, dilatation, valve incompetencies, including mitral valve leakage, and other heart failure conditions, may operate to assist in the apposition of heart valve leaflets to improve valve function. A method for improving the function of a valve of a heart includes placing an elongate member transverse a heart chamber so that each end of the elongate member extends through a wall of the heart, and placing first and second anchoring members external the chamber. The first and second anchoring members are attached to first and second ends of the elongate member to fix the elongate member in a position across the chamber so as to reposition papillary muscles within the chamber. A method of treating the valve may include real-time monitoring the valve function and adjusting the device based on data obtained during the real-time monitoring.

Devices and methods for treating heart valves include members that assist the valve in closing during at least a portion of the cardiac cycle. Such devices include members configured to alter the shape of a valve annulus, reposition at least one papillary muscle, and/or plug an orifice of the valve so as to provide a coaptation surface for the valve leaflets.
