Vanderbilt researchers have created a novel device for tissue biopsy. By combining the advantages of a core biopsy device and a FNA needle, this device is designed to combine the advantages of improving the accuracy of biopsies from small targets during CT or ultrasound guided biopsies.
This device improves the current low spatial accuracy of CT guided biopsy of small targets such as pulmonary nodules. The device also decreases adverse events resulting from oversampling/ non targeted sampling of normal lung tissue surrounding the nodule. Because a higher quality sample is obtained earlier, less needle passes are required before a sample is deemed adequate.
This needle can be used for any CT or ultrasound guided biopsy, i.e. in any part of the body and for any size of targets. For example, an initial application is designed for CT guided small lung nodule biopsies . The design incorporates a clever combination of a beveled cutting tip, a sampling notch and a nested coaxial set of tubes to provide end and side tissue sampling capabilities.
