4A Chiba Needle

The Chiba Needle is a fine-gauge, ultra-sharp diagnostic needle engineered for percutaneous fine-needle aspiration (FNA), fluid sampling, and initial access during interventional radiology procedures. Designed with a classic 30 degree bevel tip and a thin-wall cannula, it maximizes internal lumen volume for efficient fluid and cellular retrieval while minimizing trauma to surrounding parenchymal tissue. Manufactured from high-tensile stainless steel with depth markings along the shaft, the Chiba Needle ensures precise control, tactile feedback, and optimal radiopacity under ultrasound or CT guidance.

4A I.P Needle (Initial Puncture Needle)

The I.P Needle (Initial Puncture Needle) is a specialized two-part entry system designed specifically for initial percutaneous renal access during Percutaneous Nephrolithotomy (PCNL) and nephrostomy tube placement. Consisting of a sharp inner trocar stylet and an outer cannula with millimeter graduations, it enables controlled, precise entry through dense lumbar musculature and renal parenchyma into the renal calyx under fluoroscopic or ultrasound guidance.

4A Hydrophilic Guide Wire

The Hydrophilic Guide Wire is a fully polymer-jacketed interventional wire designed for low-friction navigation through highly tortuous, obstructed, or strictured anatomical pathways. Activated upon hydration with sterile saline, its durable hydrophilic coating creates an ultra-slick surface layer that dramatically reduces surface friction. Combined with a superelastic Nitinol core, it easily navigates difficult ureteral, vascular, and biliary pathways where standard wires meet resistance.

4A Lunderquist Guide Wire

The Lunderquist Guide Wire (Extra Stiff / Ultra Stiff) is a heavy-duty interventional wire designed to provide maximum structural support during complex sheath exchanges and heavy device delivery. Engineered with a high-tensile stainless steel core, it resists bending and buckling under significant axial loads. Featuring a short flexible distal tip to protect internal tissue, the Lunderquist Wire is an essential component for delivering large-bore access sheaths in PCNL, aortic stent-graft placements, and severe ureteral dilations.

4A PTFE Guide Wire (SS)

The PTFE Guide Wire (Stainless Steel) is a foundational workhorse guide wire used across general surgical, urological, and radiological procedures for standard catheterization and device exchange. Constructed from a precision-wound stainless steel coil surrounding a central core wire, it is coated with smooth Polytetrafluoroethylene (PTFE). This fluoropolymer coating lowers surface friction, minimizes tissue drag, and resists clot adhesion, providing reliable daily performance in routine diagnostic and therapeutic access.

SKU: 4A-RA-0008

4A Femoral Catheter

The Femoral Catheter is a central venous access device specifically shaped and sized for rapid percutaneous insertion into the femoral vein. Engineered for short-term vascular access during acute hemodialysis, emergency fluid resuscitation, or continuous renal replacement therapy (CRRT), it provides stable high-volume flow in critical care environments. Constructed from thermo-sensitive polyurethane, the catheter offers sufficient column strength for smooth insertion over a guide wire, then softens within the vessel to reduce vascular wall erosion and thrombosis risks.
