5.4 Caution shall be exercised when drawing conclusions from the particles found in a particular sample, especially if the sample being examined is the first from that type of machine. Some machines, during normal operation, generate wear particles that would be considered highly abnormal in other machines. For example, many gear boxes generate severe wear particles throughout their expected ...
Users should be familiar with surgical procedures and techniques involving nonabsorbable sutures before employing PROLENE suture for wound closure, as risk of wound dehiscence may vary with the site of application and the suture material used. Do not resterilize. Discard opened packages and unused sutures. As with any foreign body, prolonged contact of any suture with salt solutions, such as ...
