Abstract:
A computer processor (52) that: (1) generates a map (101, 151) of vasculature of a subject, by: (a) displaying (i) a schematic representation of the vasculature including a blood vessel (102), and (ii) on the schematic representation, a first plurality of branch-site options (104, 154); (b) receiving a user-selected first branch site, and responsively displaying (i) a schematic representation of a first branch of the vasculature that branches from the schematic representation of the blood vessel at the user-selected first branch site, and (ii) a second plurality of branch-site options; and (c) receiving a user-selected second branch site; (2) responsively to receiving the user-selected second branch site, displays the map; (3) detects a physiological parameter of the subject; and (4) responsively to the detected physiological parameter, determines a value for the parameter, and stores, in association with a location on the map, data representative of the value.
Abstract:
Devices, systems, and methods configured to assess the severity of a blockage in a vessel and, in particular, a stenosis in a blood vessel, provide visual depictions of vessel that allow assessment of the vessel and,in particular, any stenosis or lesion of the vessel, simulate one or more treatment options for the vessel, and perform treatment on any stenosis or lesion of the vessel, including guiding placement of one or more treatment devices are provided. The method can include obtaining pressure measurements from first and second instruments positioned within a vessel of a patient during a diagnostic procedure where the second instrument is moved longitudinally through the vessel; identifying a treatment option based on the obtained pressure measurements; and performing the identified treatment option, wherein a user display guides placement of one or more treatment devices associated with the identified treatment option.
Abstract:
A method of localizing a medical device in a magnetic localization field is disclosed. The medical device includes a distal region forming at least a partial loop and can be devoid of dedicated magnetic localization sensors. A conductive loop is defined by a conductive segment of the partial loop between a first end point ( e.g ., a first electrode on the distal region) and a second end point ( e.g ., a second electrode on the distal region) and a pathway connecting the end points through an electrically-conductive fluid ( e.g ., blood). A magnetically induced voltage is sensed in this conductive loop and then processed to localize the medical device within the magnetic localization field. Multiple such magnetically induced voltages from multiple such conductive loops can also be sensed and fit to a model to improve localization results.
Abstract:
An implantable biocompatible biosensor is described herein. The biosensor includes a chip layer including a plurality of holes fabricated vertically there through, a power source, one or more sensors on the chip layer and coupled to the power source and a hydrogel matrix including one or more angiogenesis stimulating factors in contact with the chip layer. The stimulating factors stimulate growth of organic material through the plurality of holes when the biosensor is implanted in a subject.
Abstract:
This invention relates to an implantable device for a physiologic sensor, comprising an implantable expandable anchor, a bridge on which the sensor is secured, as well as an optional adapting ring. The invention also relates to a method of monitoring bodily functions using the anchor and sensor. The anchor is compressed and the bridge assumes an elongated shape during delivery to a target lumen. Upon deployment at the target site, the anchor expands and the bridge bows into the interior lumen of the expanded anchor, distancing the sensor from the vessel wall. This invention also relates to a method of manufacturing said device and a method of implanting a sensor.
Abstract:
An apparatus for obtaining information regarding a biological structure(s) can include, for example a light guiding arrangement which can include a fiber through which an electromagnetic radiation(s) can be propagated, where the electromagnetic radiation can be provided to or from the structure. An at least partially reflective arrangement can have multiple surfaces, where the reflecting arrangement can be situated with respect to the optical arrangement such that the surfaces thereof each can receive a(s) beam of the electromagnetic radiations instantaneously, and a receiving arrangement(s) which can be configured to receive the reflected radiation from the surfaces which include speckle patterns.
Abstract:
A biomedical apparatus for pumping blood of a human or an animal patient through a secondary blood circuit is provided, comprising a blood pump (10), an inlet duct (11) and an outlet duct (12) for guiding blood of the patient to the blood pump (10) and back to the patient. The device further comprises a measuring device (14) for measuring a physical parameter of the heart (2) or of a blood vessel, and a controller (13) for regulating the power of the blood pump (10). The measuring device (14) is adapted to be arranged inside the heart (2) or the blood vessel, and the controller is configured to determine an estimate for an inner volume of the heart (2) or of the blood vessel based on the physical parameter and is configured to regulate the power of the blood pump (10) depending on this estimate.
