| 20080249245 | BLENDS OF AMORPHOUS AND SEMICRYSTALLINE POLYMERS HAVING SHAPE MEMORY PROPERTIES - A shape memory polymeric material has a glass transition temperature, T | 10-09-2008 |
| 20090253842 | SHAPE MEMORY POLYMERS BASED ON SEMICRYSTALLINE THERMOPLASTIC POLYURETHANES BEARING NANOSTRUCTURED HARD SEGMENTS - Thermoplastic polyurethanes having an alternating sequence of hard and soft segments in which a nanostructured polyhedral oligosilsesquioxane diol is used as a chain extender to form a crystalline hard segment constituting SMPs. The polyurethanes are formed by reacting a polyol, a chain extender dihydroxyl-terminated polyhedral oligosilsesquioxane and a diisocyanate. The polyurethanes have multiple applications including for example, implants for human health care, drug delivery matrices, superabsorbant hydrogels, coatings, adhesives, temperature and moisture sensors, etc. | 10-08-2009 |
| 20090275704 | CROSSLINKED POLYCYCLOOCTENE - Chemically crosslinked polycyclooctene having excellent shape recovery properties is prepared by ring-opening metathesis polymerization of cis-cyclooctene followed by chemical crosslinking. The crosslinked polycyclooctene can be shaped, the shape memorized, a new shape imparted with the original shape being recoverable by suitable temperature adjustment. The dependence of shape memory characteristics on degree of crosslinking was established. In addition to polycyclooctene, blends thereof with other materials such as SBR, EVA, polyurethane rubbers, and inorganic fillers can be utilized to provide chemically crosslinked products having excellent and tailored shape memory properties. | 11-05-2009 |

| 20100331954 | IMPLANTABLE MEDICAL DEVICES - A medical device includes a balloon catheter having an expandable member, e.g., an inflatable balloon, at its distal end and a stent or other endoprosthesis. The stent is, for example, an apertured tubular member formed of a polymer and is assembled about the balloon. The stent has an initial diameter for delivery into the body and can be expanded to a larger diameter by inflating the balloon. | 12-30-2010 |
| 20110054591 | IMPLANTABLE MEDICAL DEVICES - A medical device includes a balloon catheter having an expandable member, e.g., an inflatable balloon, at its distal end and a stent or other endoprosthesis. The stent is, for example, an apertured tubular member formed of a polymer and is assembled about the balloon. The stent has an initial diameter for delivery into the body and can be expanded to a larger diameter by inflating the balloon. | 03-03-2011 |
| 20110071562 | MEDICAL DEVICES - A medical device, such as, for example, a catheter, includes a tubular member having a first portion having a shape memory polymer. | 03-24-2011 |
| 20110172753 | ENDOPROSTHESES - Endoprosthesis are disclosed. | 07-14-2011 |
