Patent number: 10918479Abstract: A stent (1) used for a heart valve prosthesis and the heart valve prosthesis that includes the stent (1) and is used for heart valve replacement. The stent is configured to support a heart valve (3) and includes, along a longitudinal axis, an inflow section (8), an outflow section (6) and a transition section (7) between the inflow section (8) and the outflow section (6). The stent (1) has a contracted delivery configuration and an expanded deployed configuration. In the expanded deployed configuration, the inflow section (8) defines a concave contour that is complementary to a structure of a native valve annulus. The concave contour enables self-deployment and close adherence of the stent (1), thereby preventing its displacement and perivalvular leakage after implantation.Type: GrantFiled: October 15, 2018Date of Patent: February 16, 2021Assignee: SHANGHAI MICROPORT CARDIOFLOW MEDTECH CO., LTD.Inventors: Guoming Chen, Yu Li, Feng Huang, Lei Huang, Jianchao Han, Yihao Duan, Shaohui Chen, Qiyi Luo

Patent number: 10918485Abstract: Disclosed herein are patient-specific craniofacial implants structured for filling bone voids in the cranium as well as for simultaneously providing soft tissue reconstruction and/or augmentation for improved aesthetic symmetry and appearance. Pterional voids or defects generally result from a chromic skull deformity along with a compromised temporalis muscle or soft tissue distortion from previous surgery. When muscle atrophy occurs in the pterion, temporal hollowing generally results where there would be soft tissue but for the atrophy. The patient-specific temporal implants herein are configured to have an augmented region adjacent the temporal region of the cranium in order to account for and correct any such temporal hollowing.Type: GrantFiled: September 24, 2018Date of Patent: February 16, 2021Assignee: Plastic Surgery LLCInventor: Chad Gordon

Patent number: 10864098Abstract: Embodiments provide methods and systems for treating aneurysms using filling structures filled with a curable medium. An embodiment of a method comprises positioning at least one double-walled filling structure across the aneurysm and filling the structure(s) with a filling medium so that an outer wall conforms to the inside of the aneurysm and an inner wall forms a generally tubular lumen to provide for blood flow. The lumen is supported with a balloon or other expandable device while and/or after filling. The pressure within the structure and/or in the space between an external wall of the structure and the aneurysm wall is monitored and a flow of the medium into the structure is controlled responsive to the pressure. The pressure can also be used to determine a filling endpoint. The medium is hardened while the lumen remains supported by the balloon. The balloon is then removed after the medium hardens.Type: GrantFiled: August 21, 2017Date of Patent: December 15, 2020Assignee: Nellix, Inc.Inventors: Michael A. Evans, Gwendolyn A.
