Ultrast Gel is an in vivo biocompatible and bioexcretable sterile couplant intended for use as a scanning gel in surgical procedures, biopsies and similar sterile applications.

Ultrast Gel is used to couple sound waves between the patient and medical imaging electronic transducers during intracavitary medical diagnostic ultrasound imaging procedures, transcutaneous ultrasound image guided biopsy and aspiration, intracavity ultrasound imaging, and gel infusion sonography.

Ultrast Gel is unit dose packaged, sterilized and intended for use in all diagnostic ultrasound procedures that currently use an ultrasound coupling gel or other fluid, alone or in combination with a transducer cover, where sterility, in vivo biocompatibility and bioelimination are required.

ULTRAST Gel is available by prescription only for use by healthcare providers trained in performing the indicated procedure.

Indications for use as stated in the FDA summary.
