    • Novel approaches for a conformable vascular prosthesis delivery system are provided which overcome the limitations of existing high pressure balloons for delivering intravascular prostheses to the site of high-risk plaques. One embodiment involves a short balloon segment which is inflated at one end of the prosthesis and then pulled to traverse the length of the prosthesis, dilating the surrounding prosthesis and securing it to the vessel wall as it traverses the length of the prosthesis. The short balloon segment causes less local trauma to the vessel relative to a full length balloon. Another embodiment involves use of a self-expandable mesh to expand the surrounding prosthesis and secure it to the vessel wall. The self expandable mesh is less traumatic than a typical angioplasty balloon because of the lower radial forces applied and the relatively higher transverse flexibility of the mesh.
    • 提供了适用于血管假体输送系统的新方法,其克服了用于将血管内假体递送到高风险斑块位置的现有高压气囊的局限性。 一个实施例涉及一种短气囊段,其在假体的一端处被充气,然后被拉动以穿过假体的长度,扩张周围的假体并且当其穿过假体的长度时将其固定到血管壁。 短气囊段相对于全长气囊对血管造成更少的局部创伤。 另一个实施例涉及使用自扩张网来扩展周围假体并将其固定到血管壁。 由于施加较小的径向力和网格的相对较高的横向柔韧性,自膨胀网格比典型的血管成形术球囊创伤小。

    • An implant system may include a delivery sheath having an actuator mechanism, an anchoring assistance device including an expandable scaffold including a mid-body (114) section, a cusp interface section (116), and a crown end arrangement(118), and a replacement heart valve implant. The cusp interface section includes a plurality of loop portions (134) arranged at radial intervals about the expandable scaffold. Each loop portion is circumferentially spaced apart from another loop portion by a region (133) having a deployment ring (134), the region being configured to span a commissure of the aortic valve and extending distally a shorter distance from the distal end than the loop portions. An elongate deployment member is configured to releasably engage with the deployment rings to actuate the expandable scaffold from a delivery configuration to a deployed configuration. The replacement heart valve implant is configured to be at least partially disposed within the expandable scaffold in the deployed configuration.
    • 植入系统可以包括具有致动器机构的输送护套,包括可扩展支架的锚定辅助装置,所述支架包括中体部(114)部分,尖部接合部分(116)和冠部端部布置(118),以及 更换心脏瓣膜植入物。 尖端界面部分包括围绕可膨胀支架以径向间隔布置的多个环部分(134)。 每个环部分通过具有展开环(134)的区域(133)在周向上与另一个环部分间隔开,该区域构造成跨越主动脉瓣的连接并且远离远端远离环路延伸较短的距离 部分。 细长展开构件构造成可释放地与展开环接合,以将可扩展支架从输送构型驱动到展开构型。 置换心脏瓣膜植入物构造成在展开构型中至少部分地设置在可扩展支架内。
