The SPIWay® Endonasal Access Guide is indicated for use in endoscopic sphenoid sinus and transsphenoidal surgery.

The SPIWay®Endonasal Access Guide is a temporary working channel sheath for use in endoscopic sphenoid sinus and transsphenoidal surgery. The device consists of a single piece of thermoplastic polymer with a low friction coating, which creates a working channel sheath in the natural orifice of the nose to facilitate visualization of the surgical site and smooth manipulation of introduced instruments during transnasal endoscopic surgery. The shape of the SPIWay Endonasal Access Guide contains a flared portion at the proximal end of the device which remains outside the nasal passage and a conical body that sits within the nasal cavity. The flared proximal end and conical body act to anchor the device, preventing migration once inserted and allow simple removal. The device has an elliptical shape, and the major axis of the ellipse is oriented vertically with the nostril. The device is supplied in several lengths that are selected based upon the surgeon's needs. It is provided sterile and for single use in a pack of two, one for each nostril. A pair of devices is sealed in a Tyvek pouch and 5 pouches are placed into a labeled carton.
