The vascular scalpel is jointly invented by a cardiovascular surgeon. The Vascular Scalpel (blade and handle) has several combinations in which different angles can be created using two different blade and handle angles. The Vascular Scalpel provides lightweight and easy handling by combining a compact edge with a curved blade for improved disposal performance. The Mani Vascular Scalpel (disposable) has excellent sharpness for ACS. The Vascular Knife (Disposable) has a slanted blade that can help reduce the risk of damaging the other side of the vessel wall. This Vessel Knife (Disposable) has several different functions such as a 0 degree incision knife (FDVKE100), a 35 degree incision knife (FDVKE101) and a scraper knife (FDVKE500). All Mani vessel knives (disposable) are approximately 190 mm in size and can be sterilized with ethylene oxide.
