    Abstract: Catheters and methods are provided for performing medical procedures, such as tissue ablation, adjacent the ostia of anatomical vessels, such as pulmonary veins. The catheter comprises an elongated flexible integrated catheter body having proximal and distal shaft portions and at least one operative element carried by the distal shaft portion. The distal shaft portion has a proximal section configured to be internally actuated (e.g., using a steering mechanism or pre-shaping the proximal section) to form a simple curve with an apex that can be inserted into the vessel ostium, an intermediate section pre-shaped to form a curve that bends opposite the simple curve, and a distal section configured to be placed into a non-radial relationship (tangential or oblique) with the vessel ostium when the apex of the simple curve is inserted into the vessel ostium. By this arrangement, the operative element is configured to be placed firmly in contact with tissue at a predefined radial location relative to the vessel ostium when the apex of the simple curve is inserted into the vessel ostium.

    Abstract: The bracelet (1) is formed of several juxtaposed links (2) made of rigid material and a flexible core (3) onto which the links are threaded. The flexible core (3) is formed over a part of its length of flexible elements (4) removably assembled one after the other. Each flexible element comprises on two opposite sides a first assembling portion (7) and a second assembling portion (6) complementary to the first assembling portion. The elements can be assembled one after the other by fitting the first and second assembling portions together to form a flexible strip. The links (2) are positioned on the flexible core to hold the flexible elements in their assembled position.

    Abstract: A releasable fastener system comprises two hook portions. The hook portions each include a support and a plurality of closely spaced upstanding hook elements extending from one side thereof. When the two hook portions are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. The head elements of the hook elements are formed of a material that provides a change in directional orientation of the head elements. In this manner, the directional orientation of the head elements of the hook elements can be remotely changed to provide a reduction or magnification in the shear and/or pull-off forces.

    Abstract: Foam bedding products including viscoelastic foam having a high airflow value that do not feel hot to the person sleeping on the products. One product is a pillow having a contoured core having sufficient firmness to provide effective support for a user and a hyper soft viscoelastic foam shell surrounding the core having sufficient firmness to maintain the appearance of a conventional pillow when supporting only a pillowcase or other bed coverings. The core may be made of higher density viscoelastic foam or of a resilient foam. Another product may be a mattress topper with or without foam cores for body support carried within slabs of high airflow viscoelastic foam.

    Abstract: The instant invention is directed toward an ablation catheter and sheath incorporating wire rail system. The catheter may have a combination of rigid and flexible components to orient an ablation electrode at the distal tip toward the target tissue. The wire rail acts to guide an ablation tip along the tissue to aid in the formation of spot or continuous linear lesions on a trabecular surface, e.g., in the right atrium along the isthmus between the ostium of the inferior vena cava and the tricuspid valve.
