Nasal Dressing dissolves completely.

Press Release Summary:

Made from plant-based CarboxyMethyl Cellulose, NASASTENT Nasal Dressing minimizes bleeding and prevents post-op adhesions after sinus surgery. Structural intranasal splint can be customized by trimming to fit size needs of patient and has tapered edges for ease of placement. Once in place, dressing quickly regains its shape as it conforms to patient's anatomy. After absorbing sufficient nasal fluid, NASASTENT converts into hydrocolloidal gel and drains from cavity as part of natural outflow.

Original Press Release:

New Customizable NASASTENT(TM) Nasal Dressing from Smith & Nephew designed to Dissolve Completely

LONDON,  -- Smith & Nephew (NYSE:SNN;LSE:SN), the global, medical technology business, today announced the launch of its new NASASTENT Dissolvable Nasal Dressing, a structural intranasal splint used to minimize bleeding and prevent post-op adhesions after sinus surgery.                      

Made from a plant-based material known as CarboxyMethyl Cellulose (CMC), the NASASTENT dressing can be easily customized by simply trimming it to fit the size needs of each patient and offers tapered edges for ease of placement into the nasal cavity. Once in place, the soft dressing quickly regains its shape as it conforms to the patient's anatomy; providing sufficient pressure to minimize bleeding and hold the surrounding soft tissues in place as they heal. Recent testing shows that the NASASTENT dressing's compressive strength is six-times greater than its leading competitor and provides significantly higher tissue separation force over a variety of simulated nasal cavity gaps ranging from 7 to 10mm.(i)

Also, unlike other structural dressings which break down into fragments that must be later removed by a physician, the CMC used in the NASASTENT dressing converts into a hydrocolloidal gel after absorbing sufficient nasal fluid and simply drains from the cavity as part of the natural outflow. CMC has a well-documented clinical history with over two decades of use in the pharmaceutical(ii) and medical device(iii )industries. The NASASTENT dressing is capable of absorbing up to 16-times its dry weight in fluid and does not require any special storage conditions(iv).

"Smith & Nephew is committed to innovation that improves both the patient and the physician experience and is proud to offer pioneering technologies such as NASASTENT within our leading specialist ENT surgical portfolio," said Mira Sahney, General Manager for ENT and Gynecology.

Surgeons attending the annual American Academy of Otolaryngology Surgeons (AAO) meeting this week in Dallas will be able to learn more about the NASASTENT Dissolvable Nasal Dressing at the Smith & Nephew booth #1721.
