摘要:
An electrophysiologic catheter with an improved control handle is provided. The catheter includes a heat transfer assembly to better dissipate heat in the control handle. The heat transfer assembly includes a pump, a reservoir containing a coolant, a heat transfer member, and a coolant transport network transporting coolant between at least the reservoir and the heat transfer member. In one embodiment, the heat transfer member is located within the control handle as a heat exchanger on the circuit board to receive the coolant for transferring heat from the integrated circuits to the coolant. In another embodiment, the heat transfer member is located on the circuit board directly surrounding the integrated circuits to internally cool the integrated circuit within the control handle. A second heat transfer member is located outside of the control handle as a heat exchanger.

An oral care system comprising an oral care implement, such as a toothbrush, and dispenser containing a fluid detachably coupled to the toothbrush. In one embodiment, the dispenser includes a reservoir containing a fluid and a rotatable actuator for dispensing the fluid from the dispenser; and the dispenser is alterable between: (i) a storage state in which the dispenser is detachably coupled to the toothbrush and a mechanical interference between a portion of the rotatable actuator and a portion of the toothbrush prohibits rotation of the rotatable actuator relative to the toothbrush; and (ii) an application state in which a user can rotate the rotatable actuator to dispense the fluid from the dispenser.
摘要:
A toothbrush having an arrangement of cleaning elements for improved oral care and dentifrice retention. In one aspect, the invention is a toothbrush comprising a first set of cleaning elements forming a loop that extends from the distal periphery of the head to the proximal periphery of the head. The loop has the shape of a racetrack and comprises a first par-elliptical wall of cleaning elements at the distal periphery of the head and a second par-elliptical wall of cleaning elements located at the proximal periphery of the head. The par elliptical walls are connected first and second arcuate rows of cleaning elements. In one embodiment, the first and second arcuate rows are symmetrically arranged about the longitudinal axis so that peripheral convex surfaces of the first and second arcuate rows face the longitudinal axis.

The present invention is directed to a system, a method and a catheter that provide improved ablation capabilities and improved energy efficiency by selectively energizing catheter electrodes on the basis of impedance measurements. In particular, the invention is directed to the selective energization of catheter radial electrodes that together with a tip electrode form a generally continuous tissue contact surface, wherein the selection is made on the basis of impedance measurement as an indication of the amount of tissue contact of each radial electrode.

摘要:
An oral care implement such as a toothbrush includes a head defining a longitudinal axis and a plurality of tooth cleaning elements supported by the toothbrush head. The tooth cleaning elements preferably include at least one tooth polishing unit having a polishing element including a supporting base and a broadened flexible tooth polishing head extending angularly outwards from the base and defining a polishing surface. In a preferred embodiment, the polishing element is made of an elastomeric material. In some embodiments, the polishing element may be comprised of a plurality of individual polishing members.
