摘要：インプラントシステムは、駆動機構を有する搬送シースと、中央部と尖端接触部と頂端部とからなる固定補助装置と、心臓弁置換インプラントとを備える。尖端接触部は、拡張可能な足場の周囲に径方向に間隔をあけて配置された複数のループ部を含む。各ループ部は、展開リングを含む領域によって周方向に別のループ部から離間して配置され、領域は、大動脈弁の交連部を跨いで遠位端から遠位方向にループ部よりも短く延びる。長尺状の展開部材は、展開リングに対して離脱可能に係合して、拡張可能な足場を搬送姿勢から展開姿勢へと駆動する。心臓弁置換インプラントは、展開姿勢の拡張可能な足場内に少なくとも部分的に配置される。

摘要： An implant system may include a delivery sheath having an actuator mechanism, an anchoring assistance device including an expandable scaffold including a mid-body section, a cusp interface section, and a crown end arrangement, and a replacement heart valve implant. The cusp interface section includes a plurality of loop portions arranged at radial intervals about the expandable scaffold. Each loop portion is circumferentially spaced apart from another loop portion by a region having a deployment ring, 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.

摘要： The present invention provides a valvuloplasty catheter which has a scoring element at its distal part to score stenotic, calcified heart valves in radial direction and to make the single valve flaps/leaflets work again. In addition to this, the device could comprise an attached balloon to post-dilate the valve after the scoring procedure. To reduce a future recalcification, the scoring element and/or the balloon have a pharmacologic coating on their outer surface.

摘要： The present invention comprises a novel and safer mechanism of deployment using a self- positioning, self-centering, and self-anchoring method. To embody the present invention, a disk-based valve apparatus allowing the repositioning and retrieval of the implantable valve while working on a dysfunctional valve structure is disclosed. The disk-based valve apparatus may comprise one or more disks, either proximal or distal, a valve-housing component and a valve component. The one or more disks may be either proximal or distal, may be either connected to each other or disconnected from each other and may either be symmetrical or have different shapes and dimensions. The disk-based valve apparatus may be self anchoring, such as anchored by pressure from the one or more disk, or may be anchored using any anchoring.

摘要： 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.
摘要翻译：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。

摘要： The present invention is an apparatus and a method for delivery of mitomycin through an eluting biocompatible implantable medical device (99). A biocompatible drug release matrix comprises a biocompatible drug release matrix and a drug (55) incorporated into the biocompatible drug release matrix. The drug (55) has antibiotic and anti-proliferative properties and is an analogue related to the quinone-containing alkylating agents of a mitomycin family. The drug (55) is initially released from the biocompatible drug release matrix at a faster rate followed by a release at a slower rate. The drug (55) release rate maintains tissue level concentrations of the drug (55) for at least two weeks after implantation of the medical device (99). The present invention provides a coating for a vascular prosthesis that elutes the drug (55) at a controlled rate to inhibit proliferation of smooth muscle cells causing restenosis.
