Abstract: The present invention relates to an endoscope (2) having first conduction means configured to transmit electromagnetic waves between an illumination device (40) for illuminating an observation area (41) and a distal end (5) of the endoscope (2), and second conduction means configured to transmit electromagnetic waves between a therapy device (42) for treating a therapy area (43) within the observation area (41) and the distal end (5) of the endoscope (82). The endoscope is characterized by a third conduction means configured to transmit electromagnetic waves between an optical coherence tomography device (37) by means of which depth information about said area can be obtained during treatment of the therapy area (43) and the distal end (5) of the endoscope (2).

Abstract: A metathesized natural oil composition comprising (i) a mixture olefins and/or esters, or (ii) a metathesized natural oil, is disclosed. The metathesized natural oil composition has a number average molecular weight in the range from about 100 g/mol to about 150,000 g/mol, a weight average molecular weight in the range from about 1,000 g/mol to about 100,000 g/mol, a z-average molecular weight in the range from about 5,000 g/mol to about 1,000,000 g/mol, and a polydispersity index of about 1 to about 20. The metathesized natural oil composition is metathesized at least once.

Abstract: Natural oil based fatty acid wax compositions and their methods of making are provided. The methods comprise providing a natural oil, and hydrogenating and metathesizing the natural oil, and then converting the hydrogenated metathesized natural oil to obtain a fatty acid wax comprising free fatty acids and/or salts of fatty acids, glycerol and/or alcohol, and paraffin, wherein the fatty acid wax has at least 50 wt % of carbon chain compositions with at least 18 carbon atoms. The compositions may comprise 85-100 wt % long-chain fatty acids, 0-15 wt % esters, wherein the fatty acid comprises between 15-60 wt % long chain di-acids and 40-85 wt % long chain mono-acids. The compositions may comprise about 50-100 wt % long-chain fatty acids and about 0-50 wt % esters, wherein the fatty acid may comprise between about 15-80 wt % long chain di-acids and about 20-85 wt % long chain monoacids.

Abstract: A metathesized natural oil composition comprising a blend of (i) a high molecular weight metathesized natural oil, and (ii) at least 10% of metathesized natural oil back blended with the high molecular weight metathesized natural oil. The blend has a number average molecular weight in the range from about 300 g/mol to about 76,000 g/mol, a weight average molecular weight in the range from about 300 g/mol to about 81,000 g/mol, a z-average molecular weight in the range from about 300 g/mol to about 87,000 g/mol, and a polydispersity index of about 0.5 to about 1.5. The metathesized natural oil composition is metathesized at least once.
