The guidance of "precision key" and the accurate upgrading of interventional therapy: the interpretation of balloon catheter

Public date:2025-07-14 11:08:44  Views:

Balloon catheter is an important device in the field of interventional therapy, which is suitable for the establishment of intraoperative vascular access, the delivery of interventional equipment, and the dressing or pretreatment of the lesion through balloon dilatation.

The "core equipment" of interventional therapy: the clinical mission of balloon catheter

Balloon catheter, as the "standard weapon" of interventional surgery, undertakes three core tasks:

Vascular access construction: The passage from outside the body to the lesion site is established in a minimally invasive manner without open surgery

Device delivery bridge: provides a precise delivery platform for interventional devices such as stents and embolization materials

Lesion pretreatment tool: The stenotic/occluded vessels were rapidly opened by balloon dilatation to restore blood perfusion

According to statistics, more than 10 million interventional procedures rely on balloon catheter technology every year, from coronary heart disease intervention to neurovascular reconstruction, and its performance directly affects the success rate of surgery and the prognosis of patients.

【 Marine advantage 】

Material combination:

Outer layer: nylon, polyurethane (wear/pressure resistance)

Inner layer :Pebax, TPU(flexibility/pushability)

Precision co-extrusion technology:

There were no interface defects in the interlayer adhesion, and the delamination or rupture of the balloon was avoided

Customized design:

Slice thickness ratio was adjusted according to lesion type. (For example, high burst pressure is required in cardiovascular system and low compliance in nerve system)

【 Processing capacity 】

The inner wall thickness could reach 0.015mm.

The outer wall thickness was up to 0.05mm.

The concentricity can reach 85%

Balloon folding device up to 6 wing folds

Through the co-extrusion process without interface defects between layers, the two major pain points of traditional balloons are solved:

Eliminate hidden dangers of stratification:

The traditional single-layer balloon may delaminated due to the stress concentration of the material. The double-layer structure eliminates the hidden danger by molecular bonding

Increase blasting pressure:

After testing, the burst pressure of double-layer balloon is 30% higher than that of single-layer balloon, which is especially suitable for high pressure scenarios such as cardiovascular disease

[From "Heart" to "nerve" precise protection]

Cardiovascular intervention:

Coronary artery disease: Used for predilation of coronary artery disease before stent implantation to open occluded vessels in acute myocardial infarction

Structural heart disease: Assisted valvuloplasty to restore heart valve function without thoracotomy

Peripheral vascular and neural fields:

Lower extremity artery/renal artery: to treat arteriosclerosis obliterans and restore blood supply to the limbs

Intracranial angioplasty: for cerebral artery stenosis, to reduce the risk of stroke

Flow diverter assist: precise positioning of the device in the treatment of intracranial aneurysms

Interdisciplinary innovative application:

Urinary/digestive endoscopy: biliary stricture dilatation, ureteroplasty

Tumor intervention: assisted embolization catheter localization and increased local drug concentration
