  • Ablation Catheter Having an Optical Fiber and an Adjustment Device
    Publication number: 20190000550
    Abstract: An ablation catheter for ablating biological tissue, including an optical fiber extending through the catheter, and an out-coupling region for coupling out laser light into the external environment of the catheter, said catheter being provided with at least one adjustment device designed to bend the catheter at least in the area of the out-coupling region such that the out-coupling region can be aligned relative to the tissue to be ablated.

  • Ablation Catheter with Sensor System for Detecting the Ablation Success
    Publication number: 20180243031
    Abstract: An ablation catheter for ablation of biological tissue, including at least one optical fiber for transporting laser light along the ablation catheter and at least one coupling-out region for decoupling the laser light transported by the optical fiber from the catheter. A sensor system that continuously detects parameters, from which ablation success can be determined.

  • Coupling device for connecting an optical waveguide to an associated optical waveguide connection
    Patent number: 9759616
    Abstract: A coupling device for an optical waveguide includes an optical waveguide connection for a first optical waveguide. The coupling device includes an optical filter arranged in a beam path between a laser light source and the optical waveguide connection which reflects light of a first wavelength range or a first polarization direction and transmits light of a second wavelength range or a second polarization direction.

  • Laser applicator
    Patent number: 8790332
    Abstract: The laser applicator includes a catheter (10) having a proximal section (10a), a midsection (10b) and a distal end section (10c). It contains a light guide, the light of which is output in a decoupling portion (40). The light guide runs in a longitudinal groove on the outside of a catheter body. While the light guide (20) is continuous, the catheter is composed of catheter bodies, which are joined together at a catheter splice site (37).

  • Laser applicator
    Patent number: 8672927
    Abstract: A laser applicator includes an optical fiber with a core surrounded by a cladding. The cladding contains openings (40) for coupling radiative energy outward. To accomplish an even distribution of energy, the size of the opening increases from the proximal end to the distal end. The openings (40) are combined into groups (45), with the number of openings within a group varying. The openings (40) are of a uniform size so that the area of decoupling (13) can be produced in a simple manner.

  • Laser applicator
    Patent number: 8647335
    Abstract: A laser applicator has a catheter (12) that contains a optical fiber and a lateral decoupling area at the distal end. The end section of the strand is preformed to a loop (16) the plane of which runs crosswise to the main section (14) of the strand. This makes possible an extensive linear introduction of laser energy into the surrounding tissue. The invention is suited especially for the treatment of arrhythmia.
