  • Publication number: 20240001080
    Abstract: A medical probe, including a flexible insertion tube having a proximal segment and a deflectable distal segment, and containing first and second proximal tubular structures, first and second distal lumens, and first and second wires. The first and second proximal tubular structures are twisted around each other in the proximal segment. The first and lumens are parallel to each other in the deflectable distal segment. The first and second wires run respectively through the first and second proximal tubular structures and the first and second distal lumens. The first and second wires have respective first and second proximal ends which deflect the deflectable distal segment when the respective proximal ends are pulled.

  • Publication number: 20230114222
    Abstract: A catheter has single axis sensors mounted directly along a portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are on a linear or nonlinear single axis sensor (SAS) assembly. The catheter includes a catheter body and a distal 2D or 3D configuration provided by a support member on which at least one, if not at least three single axis sensors, are mounted serially along a length of the support member. The magnetic-based sensor assembly may include at least one coil member wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system. The joint region provides strain relief adaptations to the at least one coil member and the respective cable member from detaching.

  • Publication number: 20220117654
    Abstract: An irrigated needle electrode ablation catheter has a distal tip section with a tip electrode, a needle electrode assembly longitudinal movable relative to the catheter, and a needle centering insert in a channel in the tip electrode. The assembly has a proximal tubing and a distal needle electrode, and the insert supports the needle electrode in the channel at a predetermined separation distance from the tip electrode while enabling irrigation to flow circumferentially around the needle electrode through the channel and exit at the distal end of the tip electrode. The catheter also provides a first dedicated fluid pathway through the assembly and exits at the distal end of the needle electrode, and a second dedicated fluid pathway to supply fluid to the channel in the tip electrode, wherein the second pathway is defined by a guide tube and directed by a plunger member.

  • Patent number: 8287532
    Abstract: A catheter adapted for mapping and ablating epicardial tissue from the pericardial cavity includes a catheter body and an electrode assembly that has a tip section and a loop member lying generally within a plane, wherein the tip section includes an ablation electrode exposed on one side of the loop member and an insulation member exposed on an opposite side of the loop member. The catheter also includes a intermediate section between the catheter body and the electrode assembly, wherein the intermediate deflects the loop member and the tip section bi-directionally within the same plane. So arranged, the catheter can be safely maneuvered in the pericardial sac and swept in a side to side motion over the epicardium with the ablation electrode reliably facing and making contact with the epicardium. The tip section can include a balloon that is inflatable to push away surrounding pericardial tissue.
