简要总结
Product Name:Angiographic Catheter (Diagnostic Catheter)
Study Design:This is a prospective, single-center, interventional clinical investigation designed to assess the safety and performance of the diagnostic catheter in angiography, enrolling 73 subjects.
Eligible subjects will provide informed consent and baseline clinical data will be recorded. Pre-procedure assessments will include vital signs, a review of medical history and a vascular access evaluation. The catheter will be inserted in accordance with institutional guidelines, navigated to the target vessel, and used for contrast injection and angiographic imaging. Post-procedure, subject s will be monitored for AEs and SAEs.
Follow-ups visits will be conducted on Day 7 and Day 30. Data from each visit will be collected and recorded in CRFs, and analyzed accordingly. Safety and performance endpoints will be evaluated using descriptive statistics. The investigator will assess and categorize adverse events based on their severity and relationship to the device.
Description of the investigational device-
Diagnostic catheters are specialized diagnostic intravascular catheters used for the coronary diagnostic angiography performed as part of diagnostic cardiac catheterization. The basic design of diagnostic catheter comprises of a catheter tube having a proximal end and a distal end. A Nylon lumen extends from the proximal end of the diagnostic catheter to the distal end of the catheter and is configured to serve as a conduit for contrast media delivery, catheter flushing and pressure measurement during cardiac catheterization procedure. The lumen of the catheter is also designed to house a guidewire. The diagnostic catheter are designed to allow access into the arterial vasculature from access sites such as femoral, radial, and brachial arteries. Diagnostic catheter manufactured with different material (Polycarbonate, Pebax, Polyurethane, Polyamide, Stainless Steel, Nylon.
Primary Objective:
To assess the safety of the diagnostic catheter in angiography procedures.
Secondary Objective:
To evaluate the performance of the diagnostic catheter in successfully facilitating contrast injection and imaging.

结局指标
主要结局
The primary outcome of the study is the performance of the diagnostic catheter during angiographic procedures. This includes catheter should facilitate smooth and successful navigation through the blood vessels, ensuring stable positioning for angiographic imaging Additionally, it should enable effective contrast injection, providing clear imaging for accurate diagnosis of vascular lesions and determining the need for PTCA.
时间窗: In this clinical study, follow-ups will be conducted on the 7th day and 30th day. Data collected at each follow-up will be assessed, recorded, and analyzed to evaluate safety, performance, and any adverse events.
次要结局
- The secondary outcome of the study is the safety, the catheter is expected to have a low incidence of AEs and SAEs, including vessel perforation, thromboembolism, vasospasm, device-related infections, and complications at the insertion site. It should not cause significant trauma to vascular structures during insertion, navigation, or removal.(In this clinical study, follow-ups will be conducted on the 7th day and 30th day. Data collected at each follow-up will be assessed, recorded, and analyzed to evaluate safety, performance, and any adverse events.)
