Cook Medical launched a new set of access products for performing sialoendoscopies, or removal of salivary stones and other obstructions within the salivary duct. These include a new guide wire, a serial dilator set, the Kolenda salivary access introducer set and the NGage and NCircle salivary stone extractors.
The soft tipped wire is used to introduce dilators that expand the duct and allow for placement of a sheath through which extracters can be introduced and manipulated safely to remove salivary stones.
The salivary duct access products are available to doctors internationally and are among the new minimally invasive devices that Cook Medical has launched as part of its new Otolaryngology—Head and Neck Surgery (OHNS) clinical division. Initially, Cook MedicalOHNS will focus on products that are used to treat salivary gland disease, chronic sinusitis, vocal cord paralysis and obstructive sleep apnea, as well as products used for soft tissue repair and in interventional airway and esophageal procedures.
Cook Medical’s new salivary duct access tools create a working channel through which physicians can treat obstructive salivary gland disease. The soft-tip wire guide is used to access the salivary duct through the duct opening and maintain ductal access throughout the procedure. Flexible serial dilators are introduced over the wire to expand the opening and prepare the salivary duct for the introduction of procedural instruments. The Kolenda introducer sheath is passed over the wire to create an open working channel into the salivary duct. The sheath serves to protect the ductal wall and allow for easy insertion and removal of the procedural instruments.
The stone extractors, including the NGage and the NCircle, have baskets that are made of nitinol “memory” wire, which allows the baskets to retain their shape following torsion. The baskets are used to manipulate and remove salivary stones.
