20110218445 | NEEDLE WITH INTEGRATED FIBERS - Needles equipped with fibres allow tissue inspection based on optical spectroscopy to diagnose whether tissue is cancerous or not. This requires integration of optical fibers into needles. The problem is how to manufacture the needle having at least one fiber exit at the distal end of the needle, where the fiber does not obstruct the hollow part of the needle if present as well as does not extend beyond the outer cylinder geometry. To solve this problem we propose to manufacture the needle consisting of four parts: an inner cylinder tube, an outer hollow cylinder tube, a needle tip part with integrated fiber exit and a holder part, wherein the hollow spacing between the inner and the outer cylinder is larger or equal to the outer diameter of the fibers, the inner and the outer cylinder are mounted in the holder part and where the tip part is mounted on the two cylinders. | 09-08-2011 |
20110251494 | NEEDLE WITH OPTICAL FIBERS - Needle interventions are widely used in the field of oncology for taking biopsies of tissue in order to inspect whether tissue is cancerous or not. To make these interventions more reliable feedback of what kind of tissue is in front of the needle is required. A way to achieve this is by making use of optical spectroscopy. This requires integration of fibers into the needle. These fibers are used to deliver light to illuminate the tissue in front of the needle and to collect back the reflected light from the tissue. The present invention proposes to integrate the fiber distal ends in the slanted bevel of the needle in such a way that at least one source-detector fiber pair has a distance that is larger than the outer diameter of the needle. | 10-13-2011 |
20120029360 | NEEDLE WITH INTEGRATED FIBERS IN THE CUTTING FACETS OF THE BEVEL - A needle comprises a tip part, a holder part, a shaft, and fibers capable of transmitting light, wherein the shaft comprises a distal end connected to the tip part, and a proximal end connected to the holder part, wherein the tip part comprises a bevel, cutting facets, and at least one channel for accommodating a fiber, and wherein an end section of the fiber is located in the channel and an end surface of the fiber is located at one of the cutting facets. By way of the facets an introduction of the needle into tissue may be facilitated. A further aspect of the invention is a method for producing such a needle. | 02-02-2012 |
20120088991 | ALGORITHM FOR PHOTONIC NEEDLE CONSOLE - Needles are widely used in interventional radiology. Each medical application requires a specific needle type. The same holds for the photonic needles which analysis depends on the type of application the clinician aims for. Therefore, it is relevant to have the X-ray machine recognize the type of needle that is being used and to load the required software for the tissue analysis. It is therefore proposed to have a data link established between the imaging modality used for the acquisition of the patient anatomy (X-ray, CT, MR or US) and the system that processes optical data from the needle, so that the information from this imaging modality can be used to guide the processing. In a preferred embodiment the selection is made by reading out the code present in the disposable needle when it is connected to the console. | 04-12-2012 |

20130026367 | DETERMINATION OF A LIPID WATER RATIO - The present invention relates to an apparatus, a method and a computer program for determining a lipid-water ratio and a scattering parameter of a sample. In particular, the invention relates to an apparatus comprising a light source and a detector arranged to measure an optical parameter at various wavelengths, where the wavelengths are selected so that at two of the wavelengths the absorption coefficients for both water and lipids are substantially identical. This enables determination of a scattering parameter. A further measurement at a third wavelength enables determination of a water-lipid ratio. According to a specific embodiment, the light source and the detector are arranged in relation to an interventional device, so as to be able to examine a tissue in terms of lipid-water ratio and scattering during an intervention. | 01-31-2013 |

20130217989 | SPLITTABLE NEEDLE WITH FIBER PROBE - A needle comprises an elongated first shaft element with a C-shaped cross section and an elongated second shaft element with a C-shaped cross section. The first shaft element and the second shaft element are adapted to be detachably connected to each other. This is achieved by an overlap of respective end sections of the first and second shaft elements. 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 |
