  • Patent number: 9370447
    Abstract: A probe for endo-ocular photocoagulation procedures provides straight and curved tip configurations. A flexible tubular material, pre-formed with a radius of curvature, allows the tip to be inserted through a trocar cannula and to resume its pre-formed shape for use during a surgical procedure. Alternatively, a tubular material is pre-formed with a radius of curvature, and is stiffened by use of a preferably stainless steel tube. Inside the tubular material is a distal end of at least one optical fiber, inserted such that its tip is coterminous with the tubular material. A tube surrounds the optical fiber and is free to move along the axis of the assembly, acting to straighten the tubular and optical fiber members as it moves forward via a sliding member associated with the hand piece. Illumination energy, laser energy, or both may be supplied to the targeted surgical site.

The guiding unit establishes a guiding axis (612, 818) substantially perpendicular to the pair of parallel control planes along which guiding axis the needle-shaped object is translatable. The angular orientation of an imaging plane (204) applied by the imaging modality determines a reference for the angular orientation of the pair of parallel control planes.

  • Publication number: 20150005745
    Abstract: The present disclosure involves a process for guiding the distal end of a guide wire or working catheter as it emerges from the distal end of a guide catheter into a blood vessel. The distal end of the guide wire or working catheter is provided with an X-ray marker, a determination is made that this distal end has emerged from the distal end of the guide catheter and a fluoroscopic image of the distal end of a guide wire or working catheter is taken. This image is correlated with the length of guide wire or working catheter inserted into the guide catheter. After further advancement of the guide wire or working catheter, another fluoroscopic image of the distal end of a guide wire or working catheter is taken and this image is correlated with the length of guide wire or working catheter which has been inserted into the guide catheter.

  • Publication number: 20140378945
    Abstract: A device and method for inserting a variable stiffness catheter into a subject with a catheter body being in relatively stiff state at a first temperature and a more flexible state at a second temperature. A temperature sensitive polymer is incorporated into the catheter that varies in stiffness depending on the temperature. The stiffness of the catheter is regulated by being in thermal contact with a circulating fluid within the catheter, or by being connected to resistive members in thermal contact with temperature sensitive alloys or polymers. The variable stiffness catheter can therefore be guided through the vasculature while in a relatively flexible state, but be changed into a relative stiff state during ablation procedures.

  • Publication number: 20140371720
    Abstract: A catheter positioning system includes a catheter needle assembly comprising a catheter having a permanent hub and a needle carried in the catheter lumen. A releasable clamp is used to compress the catheter against the needle to prevent axial movement of one relative to the other. The clamp is periodically released after being moved a short distance toward the target vessel or nerve and is repositioned a short distance from the skin entry point to further advance the catheter needle assembly. The clamp is configured to be removed from the catheter by movement in a direction other than along the longitudinal axis of the catheter while the catheter hub remains in place. After successful placement of the catheter, the clamp may be snapped apart or opened along a hinge without moving the catheter from its final position.

    Abstract: A control handle for a steerable catheter body for navigation of the catheter body through a biological lumen and manipulation at a treatment site. The control handle includes a housing assembly that houses a piston assembly and a resistance adjusting assembly. The resistance adjusting assembly can be adjusted to provide the desired frictional characteristics of the user for control of the resistance between the piston assembly and the housing assembly. In one embodiment, the piston assembly is configured to provide a frictional resistance that varies dynamically to substantially match the restorative force across the range of catheter tip deflection. Other embodiments include a vibrating member that provides tactile feedback to the operator to indicate conditions at the distal end of the catheter, such as contact force.

    Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the performance of procedures in the left atrium. The access route is through the inferior vena cava to the right atrium, where a trans-septal puncture, followed by advancement of the catheter is completed. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the right atrium and through the atrial septum into the left atrium. The distal end of the sheath is subsequently expanded using a radial dilatation device.

  • Publication number: 20140330251
    Abstract: A bi-directional steerable catheter that, for a given tip deflection angle, generates a first articulation radius in a first lateral direction and a second articulation radius in a second lateral direction, the second articulation radius being different than the first articulation radius. The catheter includes two pull wire portions that can be individually and selectively put under tension to cause deflection of the tip in a corresponding lateral direction. Actuation of a first of the pull wire portions causes a shift in the neutral axis of the catheter over a portion of the steering section, resulting in articulation over a shorter length of the steering section and thus a smaller bend radius. Actuation of a second of the pull wire portions does not result in a neutral axis shift, so that articulation is over substantially the entire length of the steering section, resulting in a larger bend radius.
