NFX-1 Removal Clamp for Nonpalpable Etonogestrel Implants
The NFX-1 Removal Clamp is designed to assist healthcare providers in the outpatient removal of deeply inserted Nexplanon® and Implanon® implants—especially those that are nonpalpable or challenging to access. This page reports clinical evidence and related removal techniques from recent studies and literature.
Evidence-Based Foundations
This content reports on peer-reviewed literature highlighting modified vasectomy clamps as effective tools for removing nonpalpable etonogestrel implants after localization by ultrasound or fluoroscopy.
Removal Technique Considerations
- Suggested small incision (≤5mm) outpatient procedure
- Pre-procedural sonographic localization improves outcomes
- Clamp design emphasizes gentle implant grasping to minimize trauma
- Reported to reduce risk of implant breakage and bleeding complications
NFX-1 Clamp Overview
The NFX-1 clamp features stainless steel construction with precision tension and a slim tip profile engineered to provide control and minimize tissue injury during implant removal procedures.
Summary of Dr. Chen and Creinin’s Study
Context
The study addresses challenges removing nonpalpable or deeply inserted etonogestrel implants, which can lead to referrals or surgical removal under anesthesia.
Reported Technique
- High-frequency ultrasound accurately localized the implant prior to removal
- A small skin incision (≤5 mm) was made at the location identified by imaging
- A modified vasectomy clamp was used to gently grasp and extract the implant
- All cases were successfully removed in outpatient clinic settings without complications
Clinical Implications
The report suggests that using a small incision combined with a modified vasectomy clamp after ultrasound localization may allow for safe, efficient outpatient removal of difficult implants. This technique may minimize patient discomfort and reduce need for surgery.
“Nonpalpable contraceptive implants can be removed in the office using a modified vasectomy clamp after localization with high-frequency ultrasonography.”

Product Information
- Precision-engineered stainless steel, autoclavable
- Slim tip design for secure grasp and minimal tissue damage
- Essential tool for providers managing difficult etonogestrel implants
Indications for Use
Helpful for removal of implants that are difficult to palpate, have migrated, or are deeply inserted, especially when conventional techniques prove challenging.
Imaging Guidance
Ultrasound or fluoroscopic localization is recommended for accurate implant identification prior to removal attempts to optimize safety and efficiency.
Benefits of Clamp-Assisted Removal
Allows gentle stabilization and traction of the implant, reducing risk of breakage, bleeding, and tissue trauma compared with blunt instruments or sharp dissection.
