5 results about "Tip catheter" patented technology

A catheter tip may be a fabricated as a planar flexible circuit, e.g., via lithography, as having a first planar segment and a second planar segment that includes various electrodes on different sectors that are insulated from each other. The tip may be deformed to have a non-planar configuration, e.g., cylindrical, and then assembled onto a catheter. The catheter may be used to monitor ECG signals and temperature and to precisely deliver ablative energy to tissues via the various electrodes. ECG signals and temperature may be monitored for one sector while ablation energy is being delivered to another sector.

A movable bougie tip device includes a tip section having a tip, a holder, and a recoiled wire and a bougie section having a bougie, a silk thread, and a slide button located at a first end thereof. The slide button adjusts an angle of the tip relative to the bougie. The silk thread is disposed within a body of the bougie and extends through an outer surface of the tip from the body of the bougie through an opening and protrudes out the tip. The holder holds the silk thread at a distal end of the tip section. The tip bends at an angle ranging from 30° to 90° relative to the bougie, and the recoiled wire prevents kinking of the tip.

A catheter assembly comprises a catheter (18), a needle (12) having a sharp distal tip disposed within the catheter (18), a catheter hub (14) connected to the catheter (18) having the needle (12) passing therethrough, the catheter hub (14) including a valve (38) that selectively permits or blocks a flow of fluid through the catheter (18), a valve actuator (54) that moves between a first position and a second position, and a return member (56) that returns the valve actuator (54) from the second position to the first position, and a needle protection member (176) that encloses the sharp distal tip of the needle (12).

To provide a catheter that allows the tip of a sheath tube to be easily checked under radioscopy.SOLUTION: A catheter 10 (antegrade catheter 18) can advance along a blood vessel of a living body and includes a tubular first catheter body 24 having a first lumen 22, and a marker 26 having a radiopaque material arranged at the tip 24a of the first catheter body. The marker includes a stripe part 32a parallel to an extending direction of the first lumen.SELECTED DRAWING: Figure 2

A catheter device and drive system configured to navigate a catheter through complex, narrow tissue openings, such as lung bronchial tract openings of 3 mm or less. The device includes a proximal catheter portion housing a hollow torque shaft, and a tip catheter portion connected to the proximal portion connected to this torque shaft. The tip position of the catheter is controlled by at least one control cable / tension cable arrangement. The system uses a processor-controlled actuator that acts as a control cable while simultaneously rotating the torque shaft and at least one control cable / tension cable in a 1:1 relationship. The catheter tip is formed by a tool plate, which is equipped with various sensors and other devices and can be connected to the outside via other conduits.
