    Abstract: An imaging marker for use with a catheter, the imaging marker comprising a plurality of segments including at least two stiff segments and at least one flexible segment, wherein for each pair of stiff segments, one of the flexible segments is located therebetween such that the flexible segment is operable to function as a hinge when the imaging marker is bent. In typical embodiments, the stiff segments are visible under a medical imaging system. In some embodiments, the stiff segments are comprised of a radiopaque material which is visible under an X-ray (fluoroscopy) imaging system.

    Abstract: Methods and devices are disclosed for puncturing tissue, comprising a puncture device for puncturing tissue and a supporting member for supporting the puncture device. The puncture device is capable of being insertable within the supporting member and being selectively usable in co-operation therewith during a portion of a procedure for puncturing tissue and wherein the puncture device is usable independently therefrom during another portion of the procedure. The puncture device comprises visual or tactile markers for determining the relative positioning between puncture device and supporting member.

    Abstract: Novel and unique medical devices and associated methods are disclosed, for facilitating efficient and repeatable puncture of a tissue site while allowing vascular access from various access sites of a patient's body. Disclosed medical devices include dilators and wires usable alone or in combination and configured to facilitate tissue access and puncture at various anatomical locations from desired access sites. The medical devices each include one or more sections having sufficient flexibility for accessing the tissue site from the access site while retaining sufficient stiffness to perform one or more additional functions.

    Abstract: A method and apparatus are disclosed for providing forward fluid delivery through an energy delivery device that avoids coring when it delivers energy to a tissue. The device has a distal face defining an opening, with the distal face including at least one electrically exposed portion and at least one electrically insulated portion. An embodiment of the energy delivery device includes an elongate member defining a lumen structured to receive a fluid, and a distal face defining an aperture in communication with the lumen. The distal face includes an electrically exposed conductive portion and an electrically insulated portion. The electrically exposed conductive portion is configured such that the energy it delivers while the energy delivery device is advanced into a tissue punctures the tissue without the tissue substantially occluding the lumen and without creating embolic particles.

    Abstract: Methods and devices are disclosed for the formation of a communication between the aorta and left atrium. The method includes introducing a puncturing device, positioning the device at a location along the aorta, and advancing the puncturing device to create a pathway. The method may include: a. via an inferior artery, advancing a perforating tip of the puncturing device towards the aorta; b. positioning the perforating tip adjacent a wall of the aorta, proximate the left atrium; and c. advancing the perforating tip to perforate through the wall of the aorta and then through a wall of the left atrium, to create a pathway between the aorta and the left atrium, wherein the creation of the pathway can be confirmed with at least one of fluoroscopy, electro-anatomical mapping, pressure measurement, contrast injection, and echocardiograph.

    Abstract: Medical devices are disclosed having improved visualization of a portion of the medical device insertable into a patient's body while minimizing obstruction of fluid flow through a lumen of the device and while minimizing an increase in the outer diameter of the device attributable to the feature providing improved visualization. The device can include, for example, an imaging marker distal to lumen openings (exit ports), or, where the device comprises a tube, such as a metallic tube, an imaging marker embedded into a wall of the tube. Another embodiment includes attaching a marker to the surface on the inside of a lumen of a medical device without embedding the marker. Various alternative embodiments, methods and applications of using such devices are disclosed as well.

    IPC: A61B18/14

    Abstract: An electrosurgical device comprises an electrically conductive elongate member for traversing body vasculature defining a hollow lumen with one or more apertures at or near its distal end, wherein electrical energy can flow through the wall of the elongate member; and an energy delivery device in electrical communication with the elongate member is located distal to the end of the elongate member. The energy delivery device includes an electrode for delivering energy. Methods of using the electrosurgical device include cutting through occlusions and creating transseptal punctures.
