Implant conveying system and using method thereof

Abstract

The invention provides an implant conveying system and a using method thereof. The implant conveying system comprises a release unit, an electrolysis part, a push rod and a micro-catheter, as well asa conducting layer which is arranged on the micro-catheter, wherein an electrode end of the release unit is electrically connected to the push rod; and another electrode end of the release unit is electrically connected to the conducting layer. By adding the conducting layer on the micro-catheter as an electrode end which is required by implant release, an implant is conveyed by virtue of the micro-catheter, and meanwhile, the conducting layer, which functions as the electrode end, is conveyed into an ion solution; when the electrolysis part gets into contact with the ion solution and the release unit is electrified, a loop is defined between the conducting layer and the push rod, and the electrolysis part conducts electrolysis in the ion solution, so that the implant is released from thepush rod. According to the implant conveying system provided by the invention, harm of a conducting needle, which functions as the electrode end, to a patient is avoided, and operation pain is relieved; moreover, due to the defined loop, consumed time is shortened and stability is guaranteed, so that the release efficiency of the implant is improved; and meanwhile, the additional use of the conducting needle is avoided, and operations are further simplified.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an implant delivery system and a method for using the same. Background technique [0002] An aneurysm is a local weakness caused by disease, injury or congenital factors. Under the impact of long-term blood flow, the weak point of the arterial wall protrudes outwards and gradually expands to form a round, oval or prismatic sac bulging. [0003] There are many methods for interventional treatment of intracranial aneurysms, mainly including vascular reconstruction on the parent artery with dense mesh stenting and embolization in the aneurysm cavity. Embolization of implants (such as spring coils) in the aneurysm cavity is currently the main method for treating aneurysms. [0004] In 1991, Guglielmi et al first reported GDC embolization for the treatment of intracranial aneurysms. The implant at the distal end of the GDC is made of platinum, which is connected to the push...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide an implant delivery system and its use method, in order to solve the problem of releasing the implant from the push rod, it is necessary to insert the conductive needle into the patient's skin, so that the push rod and the conductive needle form a loop, and there is a need to form a loop. The time is long and unstable, and the user experience effect is not good, which increases the difficulty of surgical operation
