Definition of Interventional Therapy

1. Definition of Interventional Therapy

Interventional treatment is an emerging treatment method between surgery and medical treatment. To put it simply, interventional therapy is to make tiny channels with a diameter of a few millimeters on blood vessels and skin without exposing the lesion by surgery, or through the original pipeline of the human body, in the imaging equipment (angiography machine, fluoroscopy machine, CT, MR). , B-ultrasound) to treat the lesion locally under the guidance of the least traumatic treatment. Following the traditional drug therapy and surgical thoracotomy, interventional therapy ushered in a new era of modern medical treatment with its advantages of less trauma, less risk of operation, and obvious curative effect.

2. Intervention in the development trend of the material industry

Interventional materials and devices is a multidisciplinary interdisciplinary field including materials, medicine, mechanical manufacturing and physical chemistry. China has a huge demand in the fields of high-value biological materials, precision processing, and medical device evaluation and testing, but domestic related industries cannot meet the demand, resulting in the current situation where high-end materials and devices dominated by foreign-funded products can only be obtained through imports. With the continuous increase of the country’s support and investment in strategic emerging industries and the continuous strengthening of the determination to attack, the development of interventional materials and equipment will surely drive the common progress of the following related industries:

High value medical biomaterials field
The main raw materials required for interventional medical devices include stent tubing, catheters, wires, etc. are high value-added biomaterials, some of which have a unit price higher than gold, and the materials are required to have good strength, plasticity, biocompatibility, and corrosion resistance. At present, there is no mature application-oriented raw material system in China, and the drug-machine combination and drug elution process of stents, catheters, and guide wires still need to be improved. It can be expected that the development of domestic interventional therapy medical applications will definitely drive the development of high-value biomaterial technology industry.

Precision Processing Manufacturing Industry
Catheter braiding technology, shape memory alloy processing technology, guide wire processing and welding, and mechanical valve manufacturing, etc., all belong to the category of precision machining or even ultra-precision machining. The development of interventional materials and instruments, especially the development of catheter guide wires, which are currently relatively backward in domestic technology, will strongly promote the development of the precision processing and manufacturing industry. The products of the precision machining and manufacturing industry are not limited to the medical field. Precision machining technology can serve all aspects of society and promote the technological progress of the entire society.

Medical device evaluation and testing
At present, more than 85% of diagnostic and evaluation devices such as angiography machines in the domestic market rely on imports. In addition, there is almost a lack of software and equipment in the fields of structural design of interventional auxiliary devices and structural finite element simulation analysis. Interventional devices are the third category of medical devices with the strictest control. The development of interventional devices can drive the development of the evaluation and testing industry, which in turn can promote the development of interventional devices, shorten their R&D cycle, timely detect and help improve the performance of devices, and form Virtuous circle.

3. Characteristics of interventional medicine

Interventional therapy is characterized by less trauma, simplicity, safety, effectiveness, fewer complications and significantly shortened hospital stay.

3.1. For diseases that require medical treatment, the advantage of interventional therapy compared with medical treatment is that the drug can directly act on the lesion, which can not only greatly increase the drug concentration in the lesion, but also greatly reduce the drug dosage and reduce drug side effects.

3.2. For diseases that require surgical treatment, the advantages of interventional treatment over surgical treatment are:

1) It does not require surgery to expose the lesion, generally only a few millimeters of skin incision is needed to complete the treatment, with little epidermal damage and beautiful appearance.

2) Most patients only need local anesthesia instead of general anesthesia, thus reducing the risk of anesthesia.

3) Small damage, fast recovery, satisfactory effect, and little impact on normal organs of the body.

4) For malignant tumors that are difficult to treat at present, interventional therapy can limit the drug to the lesion as much as possible, and reduce the side effects on the body and other organs. Some tumors are equivalent to surgical resection after interventional therapy.

The Balloon Catheter Coating System is a special spray system designed for drug eluting balloons that provides a uniform drug coating to the balloon catheter through ultrasonic spray technology. Ultrasonic Coating System can also be used to adjust and control the deposition process of drug coatings for different liquid formulations. With the help of a special fixing device design, the entire balloon catheter can be sprayed with a maximum spraying length of 280 mm., It also has the functions of solvent doping, pre-heating, humidity control, and drying. The equipment has the characteristics of precise application amount, uniform film layer, and high utilization rate of chemical liquid. Cheersonic has extensive experience in surface coating of implantable medical devices (such as drug stents and balloons), and can provide customers with complete solutions.
