Safer. Singlepass is a small, hand-held device that works seamlessly with the biopsy procedure as it fits with an 18 Gauge guide needle or larger.
Patented, Disposable, Electrocautery Device
The Singlepass biopsy closure cautery device is the only single-use tool for co-axial biopsies that uses a patented method of cauterizing damaged tissue to prevent bleeding. This means less adverse events and less time spent in the hospital.

Improves the biopsy
With more than 27 million new cases of cancer predicted to occur in the next 17 years, improving the biopsy experience is more important than ever.
Faster. The cauterization process is quick. The single-use, disposable tool has a probe tip that “heat-seals” the tissue damaged from the biopsy in a matter of minutes.
Effective. In two case studies of 60 patients with lung, liver, or kidney biopsies, Singlepass was used to prevent bleeding. There were zero adverse events and the biopsy channels were completely blood free every time.
Decreases anxiety and hold time
Bleeding after a biopsy is a common problem. But now, with Singlepass, your patients and staff have a solution.
-
Decrease risk Because this tool can go through a biopsy guide needle and poses no new threats to at-risk patients, they can directly benefit from the safe, effective procedure. This decreases anxiety in both patients and staff.
-
Shorten hospital stay. The four to eight hour hold time that is common practice after a biopsy is to watch for adverse events. This hold time can be shortened or eliminated altogether with the effective use of Singlepass.
-
Frees up beds. If holding time is eliminated or shortened, then nursing hours and beds are freed up. This can save thousands of dollars and build patient confidence.
-
May prevent seeding. Some medical professionals have suggested this procedure may prevent tumor seeding, which is when cancer cells spread after a biopsy.
-
Modern design. Singlepass uses two AA batteries in the handle to power the cauterization. Its light-weight design is user-friendly and disposable.
“The biopsy channels were completely blood free after cauterization with confirmation by multiple imaging modalities.
Our confidence for performing co-axial biopsy procedures without potential bleeding issues has increased.”
