Within the channel formed by the shaft elements, an optical probe may be accommodated from which the shaft elements may be removed by separating the two shaft elements from each other. | 08-22-2013 |
20140046197 | CLASSIFICATION OF TUMOR TISSUE WITH A PERSONALIZED THRESHOLD - The present invention deals with discrimination of malignant tissue from normal and benign tissue in a single patient on the basis of optical spectroscopic measurements. Starting from spectroscopic measurements in normal tissue, reference values are obtained for the normal class. With spectroscopic measurements in other tissues data points can be assigned to new class(es) when the spectral characteristics fall outside a threshold defining the reference class. Thresholds between different classes can also be defined. Finding (the transition to) malignant tissue is based on comparing the spectroscopic values to the classification threshold discriminating normal and benign versus malignant tissue. Thus, the basis of normal spectroscopic measurements is tuned to the individual patient characteristic. Discriminating the normal plus benign and malignant from that reference is more efficient compared to the reference of the all patient database. | 02-13-2014 |
20140121538 | NEEDLE WITH AN OPTICAL FIBER INTEGRATED IN AN ELONGATED INSERT - A needle is proposed including a cannula or hollow shaft with a multilumen insert inside. The insert comprises at least two lumen. Both the insert as well as the cannula have bevelled ends. In the insert substantially straight cleaved fibers are present that may be connected at the proximal end to a console. At least one of the distal fiber ends in the insert may protrude more than half the fiber diameter out of the insert. Furthermore, the bevel angle of the insert is different from the bevel angle of the cannula such that combination cannula and insert is such that the fiber ends do not protrude the bevel surface of the cannula. | 05-01-2014 |

20140213911 | NEEDLE DEVICE WITH AN OPTICAL FIBER INTEGRATED IN A MOVABLE INSERT - A needle device according to the invention comprises a hollow shaft, an elongated insert and an operating means. The hollow shaft has a first distal end portion with a bevel, the elongated insert has a second distal end portion and is movably arranged within the hollow shaft, and the operating means is shiftable between a first condition and a second condition. Furthermore, the operating means is interconnected with the elongated insert, so that the second distal end portion is located within the hollow shaft and proximally to the bevel, when the operating means is in the first condition, and that the second distal end portion is located outside the hollow shaft and distally to the bevel, when the operating means is in the second condition. | 07-31-2014 |
20140236024 | MEDICAL PROBE WITH MULTI-FIBER LUMEN - The present invention relates to a medical probe which consists of a cannula with a multilumen stylet inside. The multilumen contains at least two lumen. Both the multilumen as well as the cannula may have beveled ends. In the lumen straight optical fibers (i.e.no angle end face) are present that can be connected at the proximal end to a console. The cannula, multilumen, fiber system forming the medical probe comprises at least in one of the lumen of the multilumen more than one optical fiber. Preferably the source and detector fibers for the fluorescence detection are contained in one single lumen of the multilumen. | 08-21-2014 |
20140288368 | CAPSULE CAMERA WITH VARIABLE ILLUMINATION OF THE SURROUNDING TISSUE - The invention relates to an ingestible capsule and method for in vivo imaging and/or treatment of one or more diseased areas of interest within the gastrointestinal tract of an animal or human being. The capsule comprises an image sensor; a lens system for focusing images onto the image sensor; at least one light source for illumination of the tissue area of interest, the at least one light source optionally being capable of providing optical therapeutic treatment to the diseased areas; a variable lens system located in front of the at least one light source, wherein the variable lens system comprises beam steering means and focusing means for directing and focusing the light beams from the at least one light source onto the diseased tissue areas; a control unit in communication with the image sensor, the at least one light source, and variable lens system, the control unit comprising image storing means, processing means and image transmission means; wherein the control unit correlates stored images received from the image sensor as the capsule travels through the gastrointestinal tract and controls the beam steering means and focusing means of the variable lens system to ensure that the light beams from the at least one light source are directed and focused onto the diseased tissue areas; a power source for powering the image sensor, the at least one light source and the control unit; and a non-digestible, transparent outer protective shell configured to pass through the gastrointestinal tract, housing within the image sensor, the lens system, the at least one light source, the variable lens system, the control unit and the power source. | 09-25-2014 |
