Embodiment Construction

[0057] In order to better clearly express the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0058] Described herein are mechanical delivery devices and methods for delivering neural implants. Taken together, these mechanical delivery devices can rapidly and reliably release an implant (such as a vaso-occlusive coil). This ensures that the implant is released with the least possible strain and that no part of the implant becomes lodged in the vessel or neck of the aneurysm when the aneurysm is filled. These instruments generally require mechanical deformation (deformation of a release switch or detent lock) to release and eject the implant.

[0059] for example, Figure 4 An example of the system described here is shown. In this example, the system includes an implant 401 (shown here as a coil) permanently attached to a bushing assembly 403 . The bushing assembly includes a...

Abstract

The invention relates to a mechanical embolism conveying instrument and a mechanical embolism conveying method. A vascular embolism spring ring system comprises an implantation object constituted by an embolism spring ring; a releasing lining assembly connected with the embolism spring ring; and a releasing conveying conductor (DDW) assembly. The releasing conveying conductor (DDW) assembly comprises an external pushing assembly and an internal traction conductor. The internal traction conductor comprises a far-end area having an increased diameter. The external pushing assembly also comprises a far-end spring tube provided with a flexible far-end area and a near-end micro-internal diameter tube. The object of the invention to release the spring ring by using the instrument releasing system is achieved, and complete releasing is guaranteed. Both of the reliability and the firmness of the mechanical instrument in an operation process are considered.

Description

[0001] This application claims the priority of the U.S. Patent Application No. 62348710, entitled "MECHANICAL EMBOLIZATION DELIVERY APPARATUS AND METHODS", filed with the U.S. Patent Office on June 10, 2016, the entire contents of which are incorporated herein by reference. technical field [0002] The invention relates to the field of medical devices, in particular to an implantation method and a mechanical delivery device for neurovascular implantation devices. Background technique [0003] Described herein are medical devices for placing an implant, such as an embolization device, at a predetermined location within a blood vessel or lumen of a human (or animal). For example, described herein is a catheter system based delivery device for delivery of an implant such as a coil. This device is particularly useful for delivering an embolic device such as an embolic coil through a cerebral vessel to a designated intravascular site or an aneurysm, and solves many of the existin...
