    Abstract: A system orientates and displays intra-vascular ultrasound imaging data using an acquisition processor and an image data processor. The acquisition processor acquires, during navigation of an ultrasound catheter through a vessel, for multiple individual intra-vascular ultrasound images comprising an image sequence, data representing an individual image and orientation data associated with the individual image indicating orientation of the catheter and individual image with respect to a reference position external to patient anatomy. The image data processor aligns the multiple individual intra-vascular ultrasound images with respect to the external reference position by rotating individual images of the image sequence as necessary to have substantially the same orientation with respect to the external reference position in response to the orientation data.

    Abstract: A method, system, and program product are provided for x-ray pose recovery during an endoscopic procedure. An x-ray image is taken with a C-arm at a first pose, capturing a region of an endoscope with fiducials thereon. The C-arm is moved from the first pose to a second pose at another viewing angle while maintaining the position of the endoscope. Another x-ray image is taken with the C-arm at the second C-arm pose, capturing the region of the endoscope with the fiducials thereon. The location of the fiducials on each x-ray image is determined using segmentation. An iterative optimization is performed using the locations of the fiducials in the two x-ray images to form two-dimensional projections of the three dimensional curve of the region of the endoscope with fiducials thereon to determine the three-dimensional translation and rotation of the C-arm from the first x-ray pose to the second x-ray pose.

    Abstract: High radiopacity is achieved in a polymeric marker by combining a polymeric resin, a powdered radiopaque agent having uniformly shaped particles of a specific particle size distribution and a wetting agent. The method to produce the marker calls for the blending and pelletization of these materials followed by extrusion onto support beading. The resulting supported tubing is subsequently cut to length with the beading still in place. After ejection of the beading remnant the marker is slipped into place on the device to be marked and attached by melt bonding. Marking of a guidewire allows lesions to be measured while the marking of balloon catheters allow the balloon to be properly positioned relative to a lesion.

  • Patent number: 8636715
    Abstract: Catheter devices having low profile shafts and laterally deployable members (e.g., cannulas, needles, etc.) that may be extended or advanced laterally from the catheter shaft. Also disclosed are methods for bypassing a vascular obstruction (e.g., a chronic total occlusion or other full or partial obstruction) wherein a guidewire is entrapped in a subintimal space adjacent to the obstruction. A catheter of the foregoing character is advanced over the entrapped guidewire and into the subintimal space. The laterally deployable member is then advanced or extended from the subintimal space back into the true lumen of the blood vessel distal to the obstruction. A second guidewire is then advanced through or along the laterally deployable member. The catheter and first guidewire are then removed and one or more working device(s) (balloons, atherectomy devices, setnts, etc.) is/are advanced over the second guidewire and used to establish a subintimal bypass channel through which blood may flow around the obstruction.

  • Publication number: 20140025004
    Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include a proximal shaft having a first outer diameter. A distal sheath may be attached to the proximal shaft and may have a second outer diameter greater than the first outer diameter. A trackable tip member may be attached to the distal sheath and extending distally therefrom. The trackable tip member may define a guidewire lumen therein.

  • Publication number: 20130345677
    Abstract: A catheter has an outer peripheral portion (15) in the form of a tube and an internal, wall (16, 26) within the tube forming a plurality of lumens (11a, 11b, 21a, 21b). Axially extending linear contrastradiography sections (17a, 17b, 27a, 27b) of radiopaque material are formed at a plurality of intersection points between the outer peripheral section and the wall, the peripheral extent (a, b) of the respective contrastradiography sections being different.

  • Patent number: 8585858
    Abstract: A medical catheter for inserting into a body includes a bump tubing section with proximal and distal ends, wherein the proximal end is configured to mate with a hub. The bump tubing section has an intermediate portion extending away from the proximal end with a substantially constant outer diameter and thickness, and a taper portion adjacent the distal end with generally decreasing inside and outside diameters to provide a gradually increasing flexibility toward the distal end of the bump tubing section. The bump tubing section is comprised of a polymer having a predetermined flexural modulus. A tip section is disposed distally of the distal end of the bump tubing section comprising a distal liner and a distal cover such that at least a majority of the tip section has a substantially constant stiffness and a flexural modulus substantially equal to or greater than the predetermined flexural modulus.

  • Patent number: 8556883
    Abstract: An engagement system for a surgical sensor assembly, formed of a sensing component in a fixed position and a lead wire in an electrical communication therewith. The engagement system employs a jacket of heat shrink polymeric material to hold the sensing component to the lead wire and eliminates the employment of soldering and welding and crimping which can damage such sensing components. The system is employed in combination with catheters having a lumen for control wires for surgical instruments.

  • Patent number: 8540697
    Abstract: A method for making a deflectable catheter includes positioning a flexible element along a catheter liner. A flexible element distal portion extends along at least a portion of a deflectable distal end portion of the catheter liner. At least one anchor is engaged to the flexible element distal portion. The flexible element resides radially between the catheter liner and a band extending at least part way around a perimeter of the liner. An encapsulant, positioned around at least the flexible element distal portion, forms at least a portion of a sidewall of the deflectable distal end portion of the liner. The anchor and band are within the sidewall so that the encapsulant transmits pushing and pulling forces from the at least one anchor to the deflectable distal end portion of the liner.
