  • Patent number: 7376464
    Abstract: A method and system for delivering anti-tachycardia pacing is disclosed. A cardiac rhythm management device, such as an implantable pacemaker having anti-tachycardia pacing capability, delivers anti-tachycardia pacing therapy in accordance with an anti-tachycardia pacing protocol upon detection of a terminable arrhythmia. The anti-tachycardia pacing is delivered as a burst of one or more pacing pulses at a specified coupling interval after a sensed ventricular polarization. By sensing if an evoked potential occurs, the device can determine whether or not the anti-tachycardia pacing burst has captured the ventricle and can adjust the coupling interval and/or other parameters accordingly.

  • Publication number: 20080111276
    Abstract: A grip cap for a container has a thermoplastic shell in an inverted cup shape with a top wall and a skirt bounded by a lower rim. An elastomeric layer is integrally molded to the cap shell along the outer surface of the top wall and the skirt as well as along the underside of the lower rim. This layer defines multiple spaced apart and raised vertical ribs joined by a pad at the top wall and a gasket extending along the lower rim. The ribs and the pad provide a cushion and the gasket can seal against a shoulder of the container when tightened. Also disclosed is a two-shot method of molding such a grip cap, including integral resilient material at the outer surfaces and the underside of the cap shell rim.

  • Publication number: 20070246147
    Abstract: A method for forming and stabilizing an absorbent composite web includes conforming a first web onto a forming surface having a plurality of raised nubs having upper surfaces. The first web defines a plurality of bond areas corresponding to those portions of the first web overlying the upper surfaces of the nubs. The method further includes depositing absorbent material onto the first web to form a unitary absorbent core having a plurality of holes therein. The method further includes joining a second web to the first web at the bond areas to form an absorbent composite web. The unitary absorbent core is positioned between the first web and the second web. The first web and the second web are bonded together through the holes in the absorbent core. The method further includes removing the absorbent composite web from the forming surface.

  • Publication number: 20070250026
    Abstract: An absorbent article includes a liquid pervious liner, a liquid impervious back sheet, and an absorbent composite located between the liner and the back sheet. The absorbent composite includes a first sheet, a second sheet, and a unitary absorbent core. The unitary absorbent core has a plurality of holes there through, wherein each hole has an area less than 200 mm2. The unitary absorbent core has a uniform density and is positioned between the first sheet and the second sheet. The first sheet is directly joined with the second sheet at a plurality of bond points. The bond points are located within the holes and are substantially devoid of absorbent material.

  • Patent number: 6939345
    Abstract: A first electrode is positioned within an artery proximate an implanted intravascular stent. A second electrode is positioned at a separate location relative the position of the first electrode. Electrical energy is then delivered between the first and the second electrodes to produce an electrical field adjacent the implanted intravascular stent. When a intravascular stent is implanted in a coronary artery, the delivery of the electrical energy is coordinated to cardiac cycles detected in sensed cardiac signals, where the delivery of the electrical energy between the first electrode and the second electrode occurs during a predetermined portion of the cardiac cycle.
