Abstract
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.
Claims29
An apparatus comprising:
- (a) a first fluid applicator for contacting a first portion of a medical device with a first fluid;
- and
- (b) a second fluid applicator for contacting a second portion of said medical device with a second fluid, said second fluid applicator applying said second fluid in effective isolation from said first portion of said medical device and said first fluid applicator applying said first fluid in effective isolation from said second portion of said medical device.
A method of treating a medical device comprising the steps of:
- (a) contacting a first portion of said device with a first fluid such that a second portion of said device is not significantly contacted by said first fluid;
- and
- (b) contacting said second portion of said device with a second fluid substantially different from said first fluid such that said first portion of said device is not significantly contacted by said second fluid.
An isolated vascular tissue comprising a first region treated with a surface modifying composition and a second region substantially devoid of modification by said surface modifying composition.
A vascular tissue comprising an outer decellularized portion and an inner portion substantially devoid of decellularization.
A vascular tissue comprising an outer decellularized portion and an inner decellularized portion comprising leaflets, said-leaflets substantially maintaining the mechanical properties of the native leaflets.
