The Valleylab LS10 generator contains LigaSure vessel sealing technology. It is indicated for sealing vessels up to 7mm in diameter and tissue bundles during general surgery. LigaSure technology uses pressure and radiofrequency energy to fuse vessels and lymphatics without sutures or clips. Clinical studies show LigaSure reduces operative blood loss and complications, while also decreasing procedure time and length of hospital stay compared to mechanical ligation. The generator automatically controls energy delivery, with a double beep signaling when the seal is complete.
