Matrix stents for peripheral and coronary arteries
Description of the matrix stents
Matrix stents are designed to restore the lumen of the coronary and peripheral blood vessels by catheter balloon expansion and placement of the endoprosthesis in the expanded lumen. The stents are modern and highly effective equipment used in cardiac surgery. Stents are supplied with a delivery system in the form prepared for installation in a vessel.
Specifications
Matrix stents are manufactured on high-precision laser equipment from a unique cobalt-chromium alloy marked L605 or stainless steel 316 LVM (316L). These materials are known for such qualities as strength and ductility. Molybdenum, which is also part of the cobalt-chromium holometallic stent, gives the alloy elasticity and resistance to all kinds of external influences.
By prior agreement with the consumer, the length and diameter can be of any value. The diameter of the catheter system of this stent should correspond to the diameter of the vessel. The maximum diameter of the stent after installation should be 0.5 mm higher than the nominal value of the diameter of the vessel.
Benefits
- High biocompatibility with human organs and tissues.
- Hydrodynamic compatibility.
- Effective x-ray control during implantation. Compliance with safety standards during the procedure.
- Efficient longitudinal flexibility and high radial stability.
- The optimal ratio of metal – arterial stent at the level of 12-15%.
- Easy to hold the area of stenosis of the system. Permanent effective profile at all stages of the operation.
- Ultra low profile system
Contraindications
- In the case of presence of allergic reactions to stent materials.
- Patients with cardiogenic shock.
- The use in the treatment of patients with contraindications to therapy using platelet aggregation inhibitors and / or anticoagulants.
- Used for the treatment of injuries distal to a previously installed stent.
- The use in the treatment of injuries distal to an upstream stenosis, which is not subject to preliminary dilatation, or injuries adjacent to inoperable zones with significant ailments that impede blood circulation.
- Damaged areas that cannot be covered by a single stent.
- The use in the treatment of patients with diffuse vascular diseases, expressed in a long abnormal segment of the vessel without intermediate normal sections of the vessels within this segment.
- Damage preventing the PTCA or any other intervention procedure.
- Treatment of patients with significantly curved vessels and (or) with proximal atherosclerosis, in which it is impossible to provide adequate support for the guiding catheter.
- Acute allergic reaction to contrast medium.
- Used in the treatment of patients with injuries that may interfere with proper stent positioning.p
