Area of Science:

Interventional Radiology
Medical Device Technology
Oncology

Background:

Image-guided percutaneous interventions are crucial for managing various conditions.
Accurate needle placement is vital but challenging for deep or small lesions.

Purpose of the Study:

To evaluate the efficacy of the directable needle guide (DNG) in improving percutaneous interventions.
To assess the DNG's ability to facilitate precise needle manipulation within organs.

Main Methods:

The DNG was utilized in patients undergoing sonographic or CT-guided procedures.
Procedures included needle biopsy of hepatic/splenic lesions and percutaneous ethanol injection for liver tumors.
A 21- or 22-gauge needle was directed using the DNG.

Main Results:

The DNG successfully allowed needle direction changes during advancement in all cases.
The device facilitated avoidance of critical structures like vessels and lungs.
Improved needle tip location and access route adjustment were achieved.

Conclusions:

The directable needle guide (DNG) significantly increases the safety and ease of percutaneous interventions.
DNG offers enhanced control for precise needle placement in challenging anatomical locations.
This technology shows promise for improving diagnostic and therapeutic percutaneous procedures.
