  • Patent number: 9042962
    Abstract: The present invention relates to a model based positioning system that includes a positioning device having at least one transmitter configured to be in a tracking environment, e.g. inserted into a body, a receiver having a plurality of receiver elements arranged outside the tracking environment, a control unit configured to measure amplitude and/or phase information of a signal transmitted from the at least one transmitter and received at each receiving element, and a memory unit M for storing a model for each receiving element. The control unit is also configured to estimate the position P of the positioning device by comparing the model for each receiving element with the measured received signal for each receiving element.

  • Patent number: 9034007
    Abstract: A distal embolic protection device for dedicated use in cerebral arterial blood vessels is described. The distal embolic protection device comprises a variable-thickness micro-guidewire and a collapsible filtering device mounted on the microguidewire over two mobile attachment points so that in its collapsed configuration, the thickness of the microguidewire and the filtering device at this region is less than or equal to 0.017 inch (0.432 mm) in thickness to be able to pass through existing conventional microcatheters. The mobile attachment points allow for rotatory and longitudinal mobility of the microguidewire while the filtering device is stable thereby decreasing the risk of trauma to the fragile cerebral arterial blood vessels. Preferably, the filtering device comprises an expansion assembly, e.g., a plurality of struts attached to a filter membrane that are in a folded position which self expand to the desired dimensions within the cerebral blood vessels.

  • Publication number: 20150133780
    Abstract: Embolization particles can be safely delivered to the left gastric artery of a patient by introducing the distal end of a catheter in the patient's left gastric artery, inflating a balloon located near the distal end of the catheter so that the balloon prevents blood from flowing through the left gastric artery, and injecting a mixture of particles and contrast agent into the proximal end of the catheter so that they flow through the catheter. In addition, a path is provided for blood to flow into the catheter through an opening in the sidewall of the catheter at a position that is proximal to the balloon, and out through the distal end of the catheter. This blood flow helps to carry the particles along to their destination in the distal portion of the left gastric artery. The particles are also prevented from flowing into portions of the patient's artery system that are proximal of the balloon.

  • Patent number: 9011511
    Abstract: Balloon catheters and stent delivery systems including bifurcated stent delivery systems are disclosed. An example bifurcated stent delivery system may include an elongate shaft including a proximal section, a midshaft section, and a distal section. The proximal section may include a tubular member having a plurality of slots formed therein. The slots may be arranged in one or more sections having differing slot densities. The midshaft section may include a guidewire port in fluid communication with a guidewire lumen formed in the shaft. A main branch balloon may be coupled to the shaft. A side branch balloon may be disposed adjacent to the main branch balloon. A stent may be disposed on the main branch balloon and on the side branch balloon.

  • Publication number: 20150105659
    Abstract: An energy delivery system for delivering electrical energy to tissue, includes an elongate catheter member defining a longitudinal axis and dimensioned for passage within a body vessel and an expandable treatment member mounted to the catheter member. The treatment member includes an inflatable element adapted to transition between an initial condition and an at least partially expanded condition upon introduction of an anesthetic solution within the inflatable element, an electrode for delivering electrical energy to at least the nerve tissue associated with the body vessel to cause at least partial denervation thereof and at least one aperture dimensioned to permit passage of the anesthetic solution from the inflatable element to contact the body vessel whereby the solution at least enters the body vessel to at least partially anesthetize the nerve tissue therewithin. The electrode may be mounted to at least the inflatable element of the treatment member and may be generally helical.

  • Publication number: 20150094577
    Abstract: Electrophysiology mapping and visualization systems are described herein where such devices may be used to visualize tissue regions as well as map the electrophysiological activity of the tissue. Such a system may include a deployment catheter and an attached hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. A position of the catheter and/or hood may be tracked and the hood may also be used to detect the electrophysiological activity of the visualized tissue for mapping.

  • Patent number: 8975893
    Abstract: In a method for optimization of a flow coding with switching of an additional bipolar dephasing gradient pair, used in a magnetic resonance (MR) phase contrast angiography, the strength of the flow coding is selected depending on the flow velocity in the vessels that should be depicted. MR signals of an examination region are acquired with continuously running overview measurements, with an operator-selected flow coding strength. After the selected flow coding strength is adopted automatically for the next measurement of the continuously running overview measurements, and two partial measurements with different flow codings are implemented for each selected strength and a phase difference image from the two partial measurements is calculated and depicted in real time, and the selected flow coding strength is automatically adopted for the MR phase contrast angiography.

  • Patent number: 8948848
    Abstract: Embolic protection devices and methods for capturing embolic debris. An embolic protection device includes a pigtail catheter having a lumen for housing a guidewire. The distal portion of the catheter has one or more apertures in fluid communication with the lumen and one or more radiopaque markers on the distal-most section. The device includes a self-expanding filter coupled to a side of the catheter and a movable outer sheath surrounding the catheter. The outer sheath holds the filter in a collapsed configuration when surrounding the filter. The outer sheath is proximally retracted to deploy the filter. A method of capturing embolic debris includes inserting a guidewire into a body lumen, tracking the device over the guidewire, retracting the guidewire, positioning the device using the radiopaque marker, retracting the outer sheath and deploying the filter, performing a procedure, and advancing the outer sheath to recapture the filter.
