摘要:
A method is provided for ablating a portion of the myocardium. The method includes inserting an occlusion catheter into a vessel on a heart, occluding the vessel using the occlusion catheter, inserting an ablation catheter into a chamber of the heart, positioning the ablation catheter against the myocardium, and ablating a portion of the myocardium while the vessel is occluded. The system includes an occlusion catheter having a catheter body including a tubular member having a distal portion and a bend located in the distal portion, a balloon located proximal of the bend and configured to contact an inner surface of the CS when positioned therewithin, a plurality of marker bands positioned on the catheter body, and a plurality of electrodes positioned on the catheter body. One or more electrodes or coils can be used as a reference for an electroanatomical system and can be disposed on the occlusion catheter.

A catheter for anchoring an electrode in a coronary sinus includes an elongate catheter body adapted to be inserted into a coronary sinus and at least one electrode on the catheter body. The elongate catheter body also includes at least one anchor movable between an undeployed configuration and a deployed configuration. When the anchor is in the undeployed configuration, the catheter may be introduced into and removed from the coronary sinus. When the anchor is in the deployed configuration, the anchor engages a tissue surface of the coronary sinus to inhibit movement between the catheter body and the coronary sinus, preferably without completely occluding the coronary sinus. The anchor may be a section of the catheter body having an expandable axial cross-section, an expandable member mounted on the catheter body, one or more wire anchors, or a flexible section of the catheter body.

The invention relates to a tri-surface table tennis table and method of use, the tennis table comprising a configuration achieved placing three regulation tennis table surfaces next to each other to form a symmetrical arrangement, so that two of each surface's vertexes touch another surface's vertex, with each two touching vertexes forming a 120° angle. The invention also comprises a triangular surface that fits in the hole created in the center of the tri-surface configuration to form a smooth surface holding the three tennis table surfaces together, and a trilateral net structure further comprising three pieces of net, each piece of net having an inner end and an outer end, wherein the three inner ends are attached to one another and centered on the tri-surface table tennis table and the outer ends are one hundred twenty degrees apart, running to the three touching vertexes of the three playing surfaces.

The present invention relates to deflectable access sheath assembly. The present invention relates to deflectable sheaths and catheters, including a deflectable sheath access device or introducer, wherein the deflection and movement of the sheath access device is controlled through the relative movement of a plurality of sheaths with respect to one another. Moreover, the present invention relates to catheter assemblies designed for increased flexibility.
摘要:
A water intake screen installation has a traveling water screen unit, that is positioned between a water intake and a stream of water flowing in a channel, to strain a quantity of water diverging from the channel stream towards the water intake. The screen unit includes an endless belt strainer in the form of a loop and a drive for revolving the strainer. The strainer has a screening surface, that extends in a predetermined direction of stream flow in the channel and in an upwardly direction. Means are provided for directing a backwash current, through the screening surface, towards the stream of water flowing in the channel, at an elevation below the stream surface. Material, such as refuse and aquatic life, retained on the screening surface can be dislodged by the backwash current. This current forces such material backwardly from the screening surface, into the stream of water flowing in the channel, to be carried away therewith. Also disclosed is a method of straining water from a stream with the above described screening installation that enables water to be drawn from the stream without the removal of aquatic life and refuse.
