SharkocoreTM FNB Needled

Animation video

The SharkcoreTM has six distal cutting edge surfaces, designed to increase tissue yield.

Confidence in your diagnosis

The six distal cutting edges of the SharkCore™ FNB needle are specifically designed to obtain cohesive units of tissue with intact cell architecture. By minimizing tissue stacking and fracturing, the needle can potentially provide better core samples and help gastroenterologists and pathologists make more consistent and definitive diagnoses.20

Quick Reference Guides

Beacon™ EUS Fine Needle Aspiration (FNA) System

The device is used to sample targeted sub-mucosal and extramural gastrointestinal lesions through the accessory channel of an ultrasound endoscope. 

SharkCore™ EUS Fine Needle Biopsy (FNB) System

The device is used with an ultrasound endoscope for fine needle biopsy (FNB) of submucosal lesions, mediastinal masses, lymph nodes and intraperitoneal masses within or adjacent to the gastrointestinal tract.

Clinical Evidence

Clinical Summary

Medtronic provides the following synopsis of a clinical publication involving fine-needle aspiration and fine-needle biopsy.

In memoriam: Fine-needle aspiration, birth: Fine-needle biopsy: The changing trend in endoscopic ultrasound-guided tissue acquisition.

Objective: The aim of the study was to compare fine-needle biopsy (FNB) and fine-needle aspiration (FNA) diagnostic yield for onsite and offsite sample assessment.

Conclusion: This study showed that FNB performed better than FNA for both onsite and offsite evaluation of solid mass lesions.

Clinical summary

Medtronic provides the following synopsis of a clinical publication related to the Sharkcore™ FNB needle.

Randomized controlled trial comparing the Franseen needle with a Fork-tip needle for EUS-guided fine-needle biopsy

Objective: The goal of this study was to compare the ability of Franseen and Fork-tip needles to provide histologic tissue samples and reach an accurate diagnosis.

Conclusion: Franseen and Fork-tip needles both provide a high yield of histological tissue core sample, with no significant difference in tissue quality or diagnostic accuracy.

Clinical summary

Comparing Needles and Methods of Endoscopic Ultrasound-Guided Fine-Needle

Biopsy to Optimize Specimen Quality and Diagnostic Accuracy for Patients with Pancreatic Masses in a Randomized Trial 

Objective: The goal of this study was to compare specimen quality and accuracy of diagnoses from fine-needle biopsy (FNB) needles using different collection techniques.

Conclusion: When compared with samples from 22 gauge reversebevel and Menghini tip needles, collecting FNB samples using the fork-tip or franseen needle with stylet retraction results in the highest degree of cellularity and provides diagnostics accuracy >90% in patients with suspected pancreatic cancer.

Achieve more with EUS

Improving diagnosis. Improving patient care.

Achieve a more confident diagnosis with the Beacon™ EUS delivery system.

Diagnosis of some pancreatic diseases, such as well-differentiated adenocarcinomas and autoimmune pancreatitis, may be difficult to achieve with cytologic smears.21,22

In these cases, the use of ancillary testing is critical to achieve a diagnosis. These tests require a sufficient material sample for processing histologically or as a cell block.

The Beacon™ EUS delivery system helps enhance the content and adequacy of specimens for additional diagnostic testing to improve patient care.

Making diagnosis easier

The SharkCore™ EUS Fine Needle Biopsy (FNB) System allows for consistent, predictable tissue acquisition with intact cellular architecture9,10,11,12 at the same time, it requires a significantly lower number of passes to achieve an adequate specimen, compared to the standard FNA needle (p value < 0.001)13.

Clinical evidence suggests that FNB needles could have an important role in the natural evolution of EUS-guided tissue acquisition as a tool for molecular diagnostics on formalin-fixed paraffin-embedded samples for personalized treatments.1

Safety first

According to the Centers for Disease Control and Prevention and European Agency for Safety and Health at Work reports, there are more than 385,000 and 1,000,000 needle stick injury cases annually among hospital health care workers in the United States and Europe, respectively14. Needle stick injuries increase the risk of over 20 types of infectious diseases among health care workers, including hepatitis B, hepatitis C, and HIV.14

The SharkCore™ EUS delivery system is the only EUS device designed with an automatic safety shielding feature to aid in the prevention of needle stick injury to staff.15,16,17,18,19
