Abstract: An aromatic thermal wrap comprises aromatic compounds such as camphor, menthol, essential oils and similar compounds, mixed with an absorbent material such as a silica powder and then combined with a superabsorbent polymer (SAP) to form a dry, aromatic mixture (200), and packaged in a flexible, water-permeable sachet (100). When suitably mixed with a silica powder, the aromatic compounds do not cause agglomeration or clumping of the superabsorbent polymer. Hydration of the sachet will cause the SAP to absorb water, forming a gel 210. The sachet may be produced with multiple pockets (110) that can be separated into single packets or into sets of packets to accommodate the specific application. The end user hydrates the sachet, and optionally heats or freezes the hydrated package, to produce an aromatic, thermal wrap.

Abstract: Methods and apparatus for delivering a medical instrument over the exterior of an endoscope while the endoscope is installed in the patient's body allow the use of instruments which are too large to fit through the lumena of an endoscope.
