Choosing 3Fr Flexible Biopsy Forceps for Ureter & Kidney: How AthenaGrasp™ Compares

This page is designed for clinical and purchasing teams comparing 3Fr flexible ureteroscopic biopsy forceps for upper‑tract work. It focuses on key buying criteria, neutral device categories, and when a single‑use 3Fr platform may make sense for your program.

Key Buying Criteria for Upper‑Tract Biopsy Forceps

• Outer diameter (OD) and channel size: 3Fr (≈1.0 mm) designs are intended to pass through standard flexible ureteroscope working channels while preserving deflection.
• Working length: Shafts in the ~115–120 cm range are typically needed to comfortably reach the renal pelvis and calyces in adult patients.
• Jaw style and cup design: Cup jaws (with or without teeth) and overall cup volume affect both specimen size and the potential for mucosal trauma.
• Single‑use vs reusable construction: Single‑use devices remove reprocessing steps and wear‑related variability; reusable devices may appear lower in upfront cost but carry repair and sterilization overhead.
• Backloading and handling: Ability to pass through the scope, ergonomic handle design, and how easily the device fits into existing flexible ureteroscopy technique all influence adoption.

AthenaGrasp™ is positioned as a sterile single‑use 3Fr cup‑jaw forceps with a 120 cm working length and small channel requirement, tailored to ureter and kidney biopsy via flexible ureteroscopy.

When to Standardize on a Single‑Use 3Fr Platform

Many centers now favor a single‑use 3Fr platform for upper‑tract biopsy work, using devices in the same general class as AthenaGrasp™ and other modern cup‑jaw forceps. Standardization can be especially valuable in the following situations:

• High‑volume UTUC and upper‑tract biopsy lists: Single‑use 3Fr forceps help keep jaw performance consistent from case to case, supporting more reliable grading and potentially reducing repeat “non‑diagnostic” procedures.
• Mixed inpatient–outpatient or multi‑site workflows: Eliminating reprocessing simplifies logistics across hospitals and ASCs, avoids backlogs, and makes instrument availability more predictable.
• Narrow anatomy and complex access: For calyceal or infundibular lesions where deflection matters more than maximal cup volume, a flexible 3Fr shaft preserves maneuverability and visualization.
• Infection‑control and quality initiatives: Single‑use designs remove cross‑contamination concerns related to complex distal tips and make per‑case device costs more transparent than repair and reprocessing line items.

Which Option Fits Which Facility?

• High‑volume or multi‑site programs: Single‑use 3Fr platforms can standardize performance across locations, simplify logistics, and support clear per‑case costing.
• Academic centers with fellows and research protocols: A consistent single‑use 3Fr forceps strategy reduces device variability in studies and teaching cases, supporting reproducible data and training.
• Community hospitals with mixed inventory: A phased approach can work well—introduce single‑use 3Fr forceps first for UTUC workups, complex anatomy, or higher infection‑risk cases, while maintaining selected reusable sets.
• Lower‑volume sites with robust reprocessing capacity: Reusable 3Fr forceps may remain practical if repair rates are low and the team is confident in cleaning, sterilization, and tracking processes.
