    摘要: A system for measuring real-time tissue reflection spectral characteristics during ablation includes a catheter for collecting light reflected from tissue undergoing ablation, a detection component for separating constituent wavelengths of the collected light, a quantification apparatus for generating measured light intensity data of the collected light, and a processor for analyzing the data in relation to time. A method for monitoring formation of steam pop during ablation includes delivering light to tissue, delivering ablative energy to the tissue, measuring the reflectance spectral intensity of the tissue, and observing whether the measured reflectance spectral instensity (MRSI) initially increases in a specified time period followed by a decrease at a specified rate. If the MRSI does not decrease, delivery of ablation energy continues. If the MRSI decreases within the specified time at the specified rate, formation of a steam pocket is inferred and delivery of ablative energy is decreased or discontinued.

    摘要: Technologies are provided for an opto-mechancial device is provided for enabling surgeons to rapidly simulate proposed intestinal/colorectal anastomosis cut lines and assess their impact upon tissue perfusion prior to their implementation. The pre-selection process enables a surgeon to decide upon the locations of the anastomotic cut lines that are most likely to reduce ischemia, while preserving most of the intestinal tissue length. The opto-mechanical device may simulate a cut line by applying pressure to intestinal tissue and detecting a light pattern transmitted through the intestinal tissue before and after the applied pressure. A perfusion map may be generated to estimate perfusion quality around the circumference of the intestinal tissue at the site of a simulated cut line, and the perfusion map may be displayed as a two-dimensional graphic image of the proposed anastomosis site. Once the site of the best cut line is selected, the surgeon may activate a cutting blade to implement the cut.
