6 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.

The invention discloses a one-time forming multi-cavity rubber head guide pipe pressing die which comprises an upper die, a lower die and a rubber head guide pipe, the upper die and the lower die are matched to form a plurality of cavities, the rubber head guide pipe comprises a silica gel pipe body and a cavity head, and the silica gel pipe body is provided with a plurality of cavities communicated with the cavity head. A rubber head catheter, a urinary catheterization cavity core rod, a center cavity core rod assembly and a balloon cavity core rod are contained in the cavities respectively, the tail ends of the urinary catheterization cavity core rod, the tail end of the center cavity core rod assembly and the tail end of the balloon cavity core rod are inserted into the cavity channels respectively, and the center cavity core rod assembly comprises a center cavity core rod and a center cavity outer sleeve arranged on the center cavity core rod in a sleeving mode. A plurality of bending grooves are formed in the center cavity outer sleeve, a plurality of core needle holes are axially distributed in the circumference of the center cavity outer sleeve, and water inlet and outlet cavity core needles are arranged in the core needle holes. The problem that the multi-cavity rubber head catheter is difficult to form is solved.
