摘要： A device for delivering an occlusive element includes an elongate sheath having a lumen therein. An elongate core member is disposed within the lumen and is formed from a proximal portion and distal portion connected via a joint. The distal portion of the elongate member includes a severable junction secured to the occlusive element. A marker coil is coaxially arranged around the distal portion of the elongate core member and is partially disposed inside the sheath lumen. A coil member is coaxially arranged around the distal portion of the elongate core member and coaxially arranged around at least a portion of the marker coil extending outside the lumen of the sheath. The coil member is secured at a distal end thereof to the distal portion of the elongate core member. The device resists axial compression while allowing for radial bending.

摘要： Devices for loading a collapsible implant onto a delivery catheter. In one aspect, a loading device comprises an outer tubular structure and an inner tubular structure. The outer tubular structure comprises a narrowing passage configured to receive a catheter at one end and a collapsible implant at another end. The inner tubular structure is configured to move slidably and co-axially within the outer tubular structure. The inner tubular structure comprises a carrier pin configured to move within the narrowing passage as the inner tubular structure slides into the outer tubular structure. The sliding of the inner tubular structure into the outer tubular structure causes an implant mounted on the carrier pin to collapse as the implant moves through the narrowing passage and into the distal end of a catheter. In an optional aspect, the outer tubular structure further comprises a grasper to stabilize the catheter for receipt of the collapsible implant, and the internal diameter of the inner tubular structure varies to cause the grasper to first contract and stabilize the catheter, and then expand and release the catheter, as the grasper moves into the inner tubular structure.
摘要翻译：用于将可折叠植入物装载到输送导管上的装置。在一个方面，装载装置包括外部管状结构和内部管状结构。外部管状结构包括被配置为在一端接收导管并在另一端容纳可折叠植入物的狭窄通道。内部管状结构构造成在外部管状结构内可滑动地和同轴地移动。内部管状结构包括承载销，其构造成随着内部管状结构滑入外部管状结构而在变窄的通道内移动。内部管状结构滑动到外部管状结构中，当植入物移动通过变窄的通道并进入导管的远端时，安装在承载销上的植入物塌陷。在可选方面，外部管状结构还包括抓紧器，用于稳定导管以接收可折叠植入物，并且内部管状结构的内径变化，使得抓紧器首先收缩和稳定导管，然后膨胀和释放导管，因为抓紧器移动到内部管状结构中。

摘要： A removal tool for an implanted device, including pulmonary stents, occlusive devices, valved devices, and flow-restrictive devices, is provided. The removal tool includes an elongate tube having a central passage, a slideable inner member within the passage, and a coupling member disposed on the distal end of the inner member. The coupling member of the removal tool includes a distal tip configured to pierce a membrane of the implanted device. The coupling member also includes a coil or a hook configured to engage a support element of the implanted device. A method of removing implanted devices is also provided. A removal tool is placed adjacent to the device, the distal end of the tool is moved to pierce its membrane, a portion of the tool engages the support member, and the distal end of the tool is retracted along with the implanted device.

摘要： Devices and methods for removing a foreign object from a body lumen are disclosed. An embolectomy device can include a filter basket having a plurality of filter struts forming a cage-like structure that can be expanded to circumferentially surround the incoming foreign object. A support frame including a proximal hoop and one or more rail members may be employed to support the filter basket. The support frame and filter basket can be coupled to a pusher wire that can be used to manipulate the device within the body. In certain embodiments, the filter struts may vary in thickness to impart a desired flexibility characteristic to the device. Methods of manufacturing such devices are also disclosed.
