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 Introducer Needle

The Introducer Needle is a high-precision percutaneous access instrument designed for initial vascular and non-vascular entry prior to guide wire advancement. Engineered for the Seldinger technique across interventional radiology, cardiology, and urology, it provides smooth tissue penetration with clean lumen entry. Featuring a matched stylet-cannula bevel alignment and a clear ergonomic hub, it enables immediate backflow detection while minimizing vascular wall tearing.

SKU: 4A-RA-0003

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 Hydro Tip Guide Wire

The Hydro Tip Guide Wire is an interventional guidance wire engineered with a selectively coated hydrophilic distal tip combined with a low-friction PTFE shaft. This hybrid design delivers slick, low-friction navigation across localized strictures and impacted calculi at the tip, while maintaining firm tactile control and hand grip along the main shaft. It is an ideal access solution for challenging urological and biliary procedures where precise distal tracking is required without compromising shaft handling.

SKU: 4A-RA-0005

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.

SKU: 4A-RA-0006

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.
