From November 17th to 20th, MEDICA 2025, the world’s premier medical extravaganza, grandly took place in Düsseldorf, Germany.

Amid this feast of ideas gathering global cutting-edge technology and medical wisdom, we outlined the future blueprint of the healthcare industry through frontier technologies, innovative products, and in-depth dialogues.

Chinese Solutions on the International Stage

Bringing its latest technological achievements and industry insights, Kossel explored cutting-edge trends with global partners. A number of innovative achievements and solutions across three major product lines—Peripheral Vascular, Coronary, and Electrophysiology—made a stunning debut, demonstrating the innovative vitality of Chinese medical enterprises on the global stage.

During the exhibition, we conducted in-depth negotiations with agents and physician representatives from multiple countries in Europe, the Americas, Asia, and other regions. While discussing product features, we accurately aligned with registration requirements and clinical needs, laying a solid foundation for the deepening of future cooperation.

Europe is Kossel’s key strategic market. The company successfully obtained MDR CE certification in May this year, removing critical barriers for product entry into the European market. In the future, we will continue to launch more high-quality products, continuously enhance brand influence and market share, and support the company’s long-term development in Europe.

Every medical technology event marks the starting point of a new journey. We will embark on the next phase with the trust of global partners, persist in innovative R&D, advance the global market layout in parallel, focus deeply on the application needs in the pan-vascular intervention field, and provide more innovative and practical products and solutions for physicians and patients worldwide.

From October 23 to 24, 2025, the 2025 Complex Cardiovascular Therapeutics (CCT 2025) was grandly held in Kobe, Japan. As one of the most influential academic conferences on cardiovascular interventional therapy in Asia, it shares the latest advancements in PCI therapy, structural heart disease, and surgical treatment through live surgical demonstrations, special seminars, and academic reports. The conference attracts cardiovascular experts from around the world and has become an internationally recognized high-level academic exchange platform.

As one of the few Chinese manufacturers exhibiting at CCT, Kossel made a focused appearance with a range of star products and localized solutions, showcasing the company’s latest technologies and achievements to medical professionals.

Kossel’s exhibition team received doctors and agents from Japan and other Asian countries during the conference, and conducted in-depth exchanges on concepts, strategies, new devices, and clinical research.

Focused on the pan-vascular intervention field, Kossel has been committed to bringing original Chinese medical technologies and achievements to more doctors and patients. In 2021, Kossel’s PTCA balloon obtained certification in Japan. In addition, Japan serves as one of the clinical centers for Kossel’s coronary product, the MiStent® coronary drug-eluting stent, which has gained partial market recognition and laid a foundation for product promotion. More localized products and solutions will be developed and launched in the future.

Going forward, Kossel will continue to deepen innovative R&D in the pan-vascular intervention field, advance the layout of the Asian market simultaneously, and focus closely on application needs in the pan-vascular intervention sector. It aims to provide more innovative and practical products and solutions for doctors and patients in Asia and beyond.

Recently, Kossel Medtech (Suzhou) Co., Ltd. received approval from the National Medical Products Administration (NMPA) for its independently developed Peripheral Thrombectomy Catheter (Registration No. 20253031757).

This product, together with the previously approved Medical Electric Suction Pump (Registration No. 20252141564), Disposable Suction Connection Tube (Registration No. 20252141452), Negative Pressure Collection Device (Registration No. 20252109), and the separator currently under registration, forms the “K-Rhino” Peripheral Thrombectomy System, designed for aspiration of thrombi in peripheral arteries and veins.

While the industry remains within the “comfort zone” of 8–12F, we chose to push the boundary. 14F is not a gamble on size—it is an exploration for greater efficiency in peripheral thrombectomy.

Why are existing aspiration catheters sometimes insufficient?
When the thrombus burden is high, the lesion is located distally, or the thrombus is highly adherent, do you ever find that with 8–10F catheters:
Aspiration feels inadequate?
Residual thrombus remains despite repeated attempts?
Thrombectomy is incomplete, time-consuming, with significant blood loss?
Catheter-directed thrombolysis becomes necessary afterward, carrying bleeding risks?
The root cause: Insufficient aspiration efficiency.

How to break through?
Two core factors determine aspiration efficiency:
Thrombus Removal Force: The catheter’s ability to capture thrombus
Thrombus Transport Capacity: The catheter’s ability to deliver thrombus through its lumen

1. Catheter Diameter Determines Thrombus Removal Force
Mechanical principle:

(F: thrombus removal force; P: pressure; R: catheter radius)

When the thrombus completely occludes the catheter tip, a larger catheter diameter generates a greater removal force, resulting in stronger aspiration power.

2. Catheter Diameter Determines Thrombus Transport Capacity
Mechanical principle: Hagen–Poiseuille’s Law

(Q: thrombus transport capacity; ΔP: pressure difference; R: catheter radius; η: viscosity; L: catheter length)

Thrombus transport capacity is directly proportional to catheter radius—the larger the diameter, the greater the transport efficiency.

In summary: The closer the catheter diameter is to the vessel diameter (without exceeding it), the higher the aspiration efficiency.
This is the rationale behind the 14F large-lumen aspiration concept, leading to the K-Rhino 14F Aspiration Catheter.

Three Key Facts About the 14F Aspiration Catheter
1. Deliverability
Is 14F too large for the iliac-femoral vein?
For peripheral thrombectomy, the catheter size should match the vessel diameter.
Common access: popliteal vein
popliteal vein diameter(4.5–7 mm), femoral vein (5–8 mm), iliac vein (8–12 mm).
14F catheter outer diameter: 4.66 mm—well within the vessel range and safely deliverable.
2. Blood Loss
With 14F, aspiration efficiency improves, residual thrombus is reduced, and procedure time shortens. Blood loss remains within a normal range.
Technique tip: When transparent tubing shows a sudden increase in blood flow, stop aspiration, reposition the catheter tip to the thrombus, then resume.
3. Safety
A soft distal tip minimizes vascular injury.

In Vitro Study
Objective: To analyze the correlation between catheter diameter, thrombus clearance rate, and blood loss.

Method: 8F, 10F, 12F, and 14F catheters were used to aspirate thrombi in a 7 cm iliac vein segment. Metrics: aspiration time, total blood loss, and catheter occlusion events.

Experimental Results

Experimental Conclusion
Compared with 8F, 10F, and 12F catheters, the 14F aspiration catheter demonstrated higher aspiration efficiency, lower total blood loss, and no catheter occlusion.
