Product Description

304/316L Stainless Steel Capillary Tube Tapered Tip Threaded Side-Port Needles are precision-engineered, multifunctional fluidic components designed for controlled, leak-proof fluid delivery or extraction in demanding medical, analytical, and industrial applications. These needles integrate four critical features: a precision capillary tube for fine fluid handling; a tapered (reduced-diameter) tip for precise penetration or controlled fluid egress; a threaded hub or shaft for secure mechanical connection; and one or more precision side ports for lateral fluid flow. Manufactured from corrosion-resistant 304 or 316L stainless steel, these components offer exceptional durability, biocompatibility, and chemical resistance. The combination of a tapered tip with side ports enables targeted fluid delivery while the threaded connection ensures a secure, leak-free interface—ideal for high-pressure chromatography, drug delivery systems, and specialized laboratory instrumentation.

Product Description

Laser-Cut 304/316L Stainless Steel Capillary Tube Snake Bone Cardiovascular Stents are ultra-precision, expandable tubular mesh structures engineered for endovascular applications. Manufactured through advanced femtosecond or fiber laser micromachining of medical-grade 304 or 316L stainless steel capillary tubing, these stents feature intricate, flexible “snake bone” or serpentine pattern geometries that provide exceptional radial strength, longitudinal flexibility, and conformability to vessel walls. The laser cutting process produces clean, burr-free struts with minimal heat-affected zones, preserving the material’s mechanical integrity and corrosion resistance. Post-processing treatments including electropolishing and passivation ensure a smooth, biocompatible surface that minimizes thrombogenicity and promotes endothelialization. These precision-engineered scaffolds are designed to maintain vascular patency in coronary, peripheral, and neurovascular interventions.
