Brief Summary

The Locaste 8F Delivery Catheter by Kai MedTech has been launched in China since 2022 and has been widely used clinically. It won the government tendering in many provinces in China in early 2024. As a guiding and access device, the investigational device is used in interventional surgeries. The clinical investigation plans to conduct a non-interventional post-marketing real-world study to evaluate the safety and effectiveness of the product in clinical use. The investigator shall use the Locaste 8F Guiding Catheter according to his own surgery plan and the instruction for use (IFU) of this device. The large-bore guiding catheters (also called as long guiding sheath) by global manufacturers are generally used. Locaste 8F Guiding Catheter is marketed in China and widely accepted in clinical application. By collecting data in the real-world clinical routine treatment, the effectiveness and the safety of Locaste 8F Guiding Catheter is evaluated to provide data support of further global use of this device.

Detailed Description

This clinical investigation is a single-arm, retrospective, multicenter clinical study of a medical device marketed in China. Patients with Locaste 8F Guiding Catheter used in the neurovascular interventional surgery and the surgery video of the Locaste 8F Guiding Catheter available are recruited in this study. The data on the surgery day and follow-up data within 24 hours after surgery are collected retrospectively.

This clinical investigation will be performed in accordance with the Declaration of Helsinki [5] and the applicable parts of ISO 14155：2020 Clinical investigation of medical devices for human subjects - Good clinical practice made by International Organization for Standardization except for section 5.8 informed consent and other non-relevant aspects for retrospective study. The ethic approval was achieved with the exemption of informed consent according to the local China regulations "The Guidelines for the Establishment of Ethical Review Committees for Clinical Research Involving Humans", article 5 Exemption of Informed consent.

Since this clinical investigation is a non-interventional post-market study with the intended use of the investigational device in China, this study does not apply to the scope of pre-market clinical investigation for medical device approval defined in the Medical Device Good Clinical Practice (2022) issued by the China NMPA . Thus, this clinical investigation only refers to the applicable part of the Medical Device Good Clinical Practice (2022) issued by the China NMPA.

Given the fact that this clinical investigation is a retrospective study, any serious adverse event (SAE) should have been reported according to the regulation Procedure for Monitoring and Re-evaluation of Medical Device Adverse Event (2018). No serious adverse events in this study shall be reported again. In case of any underreporting, the investigator shall report the serious adverse events according to the Procedure for Monitoring and Re-evaluation of Medical Device Adverse Event (2018).

The intended use of the investigational device approved in China is that "The device is indicated for the introduction of interventional devices into the peripheral, coronary, and neuro vasculature". The subject cohort in this clinical investigation is covered by the device use scope.
