Patent number: 9295548Abstract: A heart valve assembly includes an annular prosthesis and a plurality of guide shields removably attached around a circumference of the annular prosthesis. A plurality of elongate guide rails extend from the annular prosthesis, which are releasably retained by the guide shields. During use, the annular prosthesis is directed into a biological annulus, e.g., with the guide rails retained by the guide shields, and secured to tissue surrounding the biological annulus using fasteners. The guide rails are released from the guide shields, and a valve prosthesis is advanced over the leaders and through a passage defined by the guide shields towards the annular prosthesis. The guide rails may include retentions elements that secure the valve prosthesis to the annular prosthesis. The guide shields are removed from the annular prosthesis, the guide rails are separated from the annular prosthesis, and are removed from the biological annulus.Type: GrantFiled: April 30, 2007Date of Patent: March 29, 2016Assignee: Medtronic, Inc.Inventors: Michael J.

Patent number: 9053944Abstract: A semiconductor device has a plurality of closely spaced fins each coated at its top and sidewalls with a SiGe layer used for improving charge carrier mobility in a channel portion of the device. The sidewalls of the closely adjacent Fins are selectively thinned so as to prevent an undesired bridging of SiGe material between immediately adjacent ones of the Fins. A method of manufacturing the same comprises: providing a substrate having a plurality of tri-gate transistors, at least two fins of the tri-gate transistors being closely adjacent to each other, where respective top and sidewall surfaces of the fins are coated with a SiGe layer; performing a tilted ion implantation on the SiGe coated fins so as to partially convert the SiGe material into a predetermined etch resistant material (e.g., and oxide of the SiGe); and etching away the non-converted sidewall parts of the SiGe coating layers so as to provide greater spacing between the immediately adjacent sidewalls of the SiGe coated fins.Type: GrantFiled: February 13, 2014Date of Patent: June 9, 2015Assignee: SEMICONDUCTOR MANUFACTURING INTERNATIONAL (SHANGHAI) CORPORATIONInventor: James Hong

Patent number: 8916413Abstract: The present invention discloses a phase change memory and a manufacturing method thereof. The phase change memory according to the present invention uses top electrodes provided on the top of storage nodes to heat the storage nodes such that a phase change layer in the storage nodes undergoes a phase change. In the phase change memory of embodiments of the present invention, the contact area between the top electrode and the storage node is relatively small, which is good for phase change. Moreover, each column of storage nodes is connected by the same linear top electrode, which can improve photo alignment shift margin.Type: GrantFiled: October 19, 2012Date of Patent: December 23, 2014Assignees: Semiconductor Manufacturing International (Shanghai) Corporation, Semiconductor Manufacturing International (Beijing) CorporationInventors: Minda Hu, James Hong
