®Fire is Micro-Invasive A bioabsorbable stent with thinner stent beams and covered with sirolimus was developed.Professor Xu BoReproduce the unique advantages of Firesorb® BRS in combination with the latest research progress of FUTURE series. The FUTURE-I study, as a FIM study using Firesorb® BRS, preliminarily proved the feasibility and safety of Firesorb® BRS. followed byThe one-year follow-up results of the prospective, multicenter, randomized controlled trial FUTURE-II showed that the Firesorb® BRS stent had no significant effect on late lumen loss and stent beam coverage. Inferior to control stents and did not find any late stent beam disruption or lumen collapse. The 2-year follow-up results of the much-received FUTURE-II study have also been officially announced. The excellent study results once again confirmed the safety of the new generation of thin-walled Firesorb® BRS stents Sexuality and effectiveness. The 2-year follow-up results of the FUTURE-II study showed that the incidence of target lesion failure (TLF) in patients with Firesorb® BRS stent implantation was 3.8%, PoCE (all-cause death, all myocardial infarction or any blood supply) The incidence of reconstruction) was 11.3%, which was non-inferior to the control stent group (Fig. 1), and there was no significant difference in each composite endpoint, especially in terms of safety indicators, patients implanted with Firesorb® BRS stent showed a trend toward lower rates of cardiac death and device-related thrombotic events (Figure 2).

span>In addition, the researchers also explored subgroup analysis, grouping the enrolled patients according to the size of the vessel diameter. The results showed that there was no significant difference in the stent beam coverage rate at 1 year after surgery and the incidence of TLF events at 2 years after surgery between the Firesorb® BRS stent group and the control stent group. The proportion of late lumen loss after implantation of the Firesorb® BRS stent was slightly higher in middle-stage patients, which needs to be systematically verified in the future. (Figure 4).

In conclusion, the results of the FUTURE-II study showed that the Firesorb® BRS stent was non-inferior to the control stent in terms of the primary end point of late loss and the secondary end point of stent beam coverage. And the two-year incidence of adverse clinical events including TLF, PoCE and stent thrombosis continued to be low, confirming that Firesorb® BRS stent can be used for the treatment of uncomplicated primary coronary lesions , providing a chance to make a comeback for bioabsorbable stents with PLLA as the main body of the stent! Now that the FUTURE-III study has also completed the enrolment work, we look forward to the publication of the research results to bring new inspiration to more experts and scholars in the industry!
Expert Comments
Professor Dou Kefei:< /span>Through the results of the FUTURE series, it can be found that the Firesorb® BRS stent is superior in terms of late lumen loss, complete protrusion of the vessel wall or composite endpoints. They are not inferior to or even superior to mainstream drug-eluting stents. Although the current indication for implantation of this stent is only for uncomplicated coronary artery disease, as Professor Xu Bo said, Firesorb® BRS The stent has the ability to treat complex coronary lesions. It is believed that with the publication of more evidence-based evidence, the Firesorb® BRS stent will be approved for the treatment of patients with complex coronary lesions in the near future. We look forward to the launch of the Firesorb® BRS stent as soon as possible!

Introduction to Minimally Invasive Argus™ OCT
3F FOR YOU Minimally Invasive ® sup>Coronary Coronary Heart Disease Total Solution Medical Solution
The advent of the era of non-implantation intervention, the widespread application of DCB, especially the re-understanding and re-application of bioabsorbable stents, OCT has become a coronary intervention therapy Professor Jingbo Hou elaborated on the Minimally Invasive Argus™ Features of the OCT system.The minimally invasive Argus™ OCT system consists of the ArgusClarity® OCT imaging system and the NOPURGE® imaging catheter. NOPURGE ®The imaging catheter adopts patented technology, simple structure, no Luer port at the proximal end, and fully closed at the distal end, plug and play, no need to rinse the distal lens, the lens does not contact blood, avoids damage to the lens by the guide wire, reduces the The use of contrast media simplifies the surgical procedure, especially when multiple withdrawals are required, greatly shortens the operation time, solves all the clinical problems caused by flushing the lumen, and the imaging quality is consistent with foreign OCT products. NOPURGE® The proximal end of the imaging catheter core is an optical fiber connector, and the distal end is an optical fiber lens. The integrated design of the optical fiber without solder joints makes the imaging catheter have good anti-breakage and bending ability, which can reduce the occurrence of catheter fracture; the front end of the imaging catheter Covered with Surskin hydrophilic coating, which can reduce the friction between the imaging catheter and the blood vessel after activation with heparin saline, and improve the passage and pushability of the catheter in the blood vessel. The smallest outer diameter of the distal end of the imaging catheter and tip-lens The distance can help the catheter to reach stenosis, smaller diameter and further vascular segments, and can provide intravascular imaging information of the distal longer segment. The NOPURGE® imaging catheter has 3 imaging rings at the front end, The distal end of the catheter, the position of the lens, and the proximal end of the catheter are respectively marked, and a reference scale for real-time evaluation of the scanning range is provided. The 1-meter mark in the middle of the catheter can feedback the length of the catheter in the patient’s body. When advancing and retreating the imaging catheter, the operator will be reminded to control Speed and strength. The ArgusClarity® imaging system achieves quantum limit low-noise light transmission through patented technology, making the OCT detection image clearer and reaching the same level as imported brands. ArgusClarity® OCT The wider range of scanning in blood vessels makes it possible to explore blood vessels with larger diameters; ArgusClarity® has a high resolution rate of 10 μm, and in the scanning range of 2.0 mm-3.5 mm, the image The branch office rate can reach the same level as imported brands.In general, the minimally invasive Argus™ OCT system has excellent features such as clear visibility, clear identification, accurate matching, no flushing, easy passage, and good positioning. Compared with other brands of OCT, the relative error level of the clear stent length in the Minimally Invasive Argus™ OCT group did not exceed ±10%, the measurement performance of the two was comparable, and the main evaluation index of effectiveness reached expectations, and there was no related test equipment during the test. of adverse events and serious adverse events, the safety of Minimally Invasive Argus™ OCT products is guaranteed!
