600465000 | Blood flow measurement | 7 |
20090281431 | Oesophageal Doppler Monitoring Probe Having a See-Through Boot - An oesophageal Doppler monitoring probe tip for use with an oesophageal Doppler monitoring probe include a first end coupled to an elongated flexible shaft, a molded substrate and an ultrasound transducer assembly affixed to the molded substrate. The probe tip also includes a see-through boot encapsulating the molded substrate and ultrasound transducer assembly. In certain embodiments, the additional use of a see-through sealant material may be used to affix or secure one or more components of the ultrasound transducer assembly in place. | 11-12-2009 |
20090287088 | LUMINAL CLIP APPLICATOR WITH SENSOR AND METHODS FOR OCCLUDING BODY LUMENS - A method for occluding a body lumen includes providing a clamping device having a pair of opposed pressure applying jaws, providing a sensor on one of the pressure applying jaws for sensing blood flow through a body lumen, and releasably securing a luminal clip between the pressure applying jaws. The method includes using the sensor for detecting blood flow through the body lumen for locating the body lumen, positioning the luminal clip adjacent the located body lumen, and closing the pressure applying jaws for clamping the luminal clip over the body lumen for at least partially occluding blood flow through the body lumen. | 11-19-2009 |
20130030303 | Combination Sensor Guidewire and Methods of Use - The present invention provides for an improved combination sensor tip that includes an ultrasound transducer and a pressure sensor both disposed at or in close proximity to the distal end of the combination sensor tip. The present invention also provides for an improved connector to couple a guide wire to a physiology monitor that reduces torsional resistance when maneuvering the guide wire. | 01-31-2013 |
20140288431 | SUBJECT INFORMATION ACQUISITION APPARATUS, SUBJECT INFORMATION ACQUISITION METHOD, AND PROGRAM - A subject information acquisition apparatus of the present invention includes a transmission/reception unit including a plurality conversion elements which transmit an elastic wave to the subject and receive a reflected wave that is reflected at each position in the subject, a scan line signal acquisition unit which acquires a plurality of signals corresponding to the reflected waves from each position in the subject as scan line signals by using a plurality of reception signals outputted from the conversion elements, and a processing unit which acquires moving information of the object by using the plurality of scan line signals. The processing unit acquires the moving information of the object on the basis of a distribution of cross-correlation values on a plane represented by two axes including an axis of time difference and an axis of distance difference by using a plurality of cross-correlation values between scan line signals at different positions. | 09-25-2014 |
20150032007 | METHOD AND SYSTEM FOR DETECTING CARDIAC TAMPONADE IN A PATIENT - System for indicating a possibility a cardiac tamponade occurring in a patient, comprising: —a right atrium pressure sensor, configured for measuring a right atrium pressure in a right atrium of the patient; —an intra pericardial pressure sensor, configured for measuring an intra pericardial pressure in a portion of an intra-pericardial space of the patient; —a processing device that is operatively connected to the pressure sensors, is provided with a predetermined statistical distribution of pressure versus tamponade probabilities, and is configured for: —determining a trans-mural pressure difference between the right atrium pressure and the intra pericardial pressure; —comparing the trans-mural pressure difference with the statistical distribution, and —indicating the possibility of cardiac tamponade occurrence, based on the trans-mural pressure difference comparison. | 01-29-2015 |
20150305679 | SYSTEMS AND METHODS FOR EVALUATING HEMODIALYSIS ARTERIOVENOUS FISTULA MATURATION - The invention relates to evaluation of maturity of arteriovenous (AV) fistula using guidewires that measure intravascular blood flow and/or pressure. The invention provides methods of evaluating AV fistula maturation using an instrumented guidewire to measure intravascular flow and/or pressure. By using a small diameter guidewire that does not interfere substantially with the flow, an accurate measurement can be made that is useful for identifying when a fistula is mature and therefore ready to be used for hemodialysis. The flow of blood through the fistula is measured using the guidewire and the measured flow and/or pressure of blood is used to determine if the fistula is mature. | 10-29-2015 |
20220133235 | SENSOR HAVING AN ADAPTED HOUSING - The present invention relates to a sensor comprising a housing; at least a sensor element arranged within the housing; plurality of elongate structures providing one or more slots; a front end and a back end provided by the housing; wherein the one or more slots are arranged between the front end and the back end of the housing; and wherein the one or more fingers are configured to receive the sensor element extending within the one or more slots. Furthermore, a device comprising the sensor and a method for manufacturing the sensor is provided. | 05-05-2022 |
