摘要： A delivery assembly comprises a delivery apparatus and a prosthetic valve releasably connected to a cord-retaining device of the delivery apparatus by a plurality of cords or tethers. The cords desirably have a multi- stranded construction formed from a plurality of strands of material. The multi-stranded construction can be, for example, a braided construction, a twisted construction, or a whip-stitch construction. The multi-stranded construction can include integral openings along opposing end portions of each cord. Each cord can extend through an aperture in an apex of the frame of the prosthetic valve or around an apex with one end portion of the cord being retained on the cord-retaining device and another end portion of the cord being retained on a slideable release member of the delivery apparatus.

摘要： Aspects of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a variable diameter inner liner wound in a spiral slidable configuration and an outer layer. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during application of a radial outward force by passage of a medical device through the sheath.

摘要： Disclosed embodiments of introducer devices provide hemostatic sealing and allow a delivery catheter to be inserted through the introducer seals without the use of a separate loader device that covers a medical device that is mounted on the catheter. Some disclosed introducers comprise a housing, a distal sheath extending distally from the housing and adapted to be inserted into a patient's vasculature, a distal hemostatic seal mounted within the housing and a proximal hemostatic seal mounted within the housing, and a slidable tube positioned within the housing that is movable longitudinally relative to the distal hemostatic seal between a proximal position and a distal position, wherein in the proximal position a distal end of the tube is positioned proximal to the distal hemostatic seal with the distal hemostatic seal closed, and wherein in the distal position the distal end of the tube extends through the distal hemostatic seal.

摘要： Pinch devices and access systems that can be used to secure a prosthetic heart valve to a heart valve annulus and to treat valvular insufficiency. A pinch device can be a separate expandable element from the prosthetic heart valve that is first advanced to the annulus and deployed, after which an expandable prosthetic heart valve can be advanced to within the annulus and deployed. The two elements can clamp/pinch the heart valve leaflets to hold the prosthetic heart valve in place. The pinch device can have a flexible, expandable annular frame. A combined delivery system can deliver the pinch device and prosthetic heart valve with just a single access point and aid more accurate coaxial deployment. The pinch device can be mounted near distal end of an access sheath, and a catheter for delivering the prosthetic heart valve can be passed through a lumen of the same access sheath.
摘要翻译：可用于将假体心脏瓣膜固定到心脏瓣膜瓣环并用于治疗瓣膜功能不全的捏夹装置和通路系统。夹紧装置可以是与假体心脏瓣膜分离的可扩张元件，其首先被推进到瓣环并展开，之后可扩张的假体心脏瓣膜可被推进到瓣环内并展开。这两个元件可夹住/夹紧心脏瓣膜小叶以将人造心脏瓣膜保持在适当位置。夹紧装置可以具有柔性的可扩展的环形框架。联合输送系统可以仅通过一个接入点输送夹紧装置和假体心脏瓣膜，并有助于更精确的同轴部署。夹紧装置可以安装在进入护套的远端附近，并且用于输送人造心脏瓣膜的导管可以穿过相同进入护套的内腔。
