An organic-inorganic hybrid material is disclosure. The organic-inorganic hybrid material contains 5˜50 wt % of inorganic compounds and has a characteristic peak at 1050±50 cm.sup.−1 in FTIR spectrum. Furthermore, the invention also provides a fabricating process of the organic-inorganic hybrid material as well as its starting material “isocyanates”. In particular, the isocyanates are prepared from carbonate containing compounds and amines.

Transluminally implantable cardiac valves configured for use in cardiac valve replacement and/or cardiac valve exclusion that are capable of percutaneous delivery on low-profile catheters having 15 French size or less. The implantable cardiac valves are fabricated of from a unitary metal material to form a lattice frame support having a main body portion and valve leaflet portion, and a plurality of elongate biasing arm members. A polymer coating or covering is disposed on the valve leaflet portion and the elongate biasing arm members and subtends space between adjacent pairs of elongate biasing arm members to form valve leaflet portions in which the elongate biasing arms and the polymer coating operate to share a mechanical load thereupon.

The present invention relates to a microballoon. The microballoon is made of polyurethane (urea). The microballoon is characterized in that an inner surface of the microballoon contains ionic groups. According to the present invention, through use for a CMP polishing pad, affinity with a slurry liquid for polishing is improved, and thus it is possible to provide a microballoon by which good polishing characteristics may be exhibited without lowering the resin strength of a polishing pad.
