  • Publication number: 20200011590
    Abstract: A resilient gasket for an appliance defines a longitudinal direction. The gasket includes a base, a pocket attached to the base, and at least one internal component located within a chamber defined by the pocket. The internal component includes a first leg extending along the longitudinal direction of the gasket from a first end of the internal component to a first side of an arcuate portion of the internal component and a second leg extending along the longitudinal direction of the gasket from a second end of the internal component to a second side of the arcuate portion of the internal component.

  • Publication number: 20180299189
    Abstract: A resilient gasket having a multi-piece construction that can be readily manufactured. The gasket includes a body having at least one, non-attached component positioned inside that provides additional resiliency. The body and the non-attached, internal component can be constructed from materials having different properties so as to determine or tune the overall resiliency of the gasket. The gasket can be provided as rails surrounding an opening of the appliance.

  • Patent number: 9622886
    Abstract: An expandable prosthetic device and method of delivery that allows the initial placement of multiple guidewires into selected target sites. The prosthesis includes a main body device. This main body device has a separate side branch guidewire lumen that passes through the main body device and through a side opening in the main body device. As the main body device is advanced, the side opening is self guided (by the side branch guidewire) and self-aligns to the side branch vessel ostium. The main body device is then deployed, leaving the side branch guidewire in place. A side branch device is then advanced along the side branch guidewire through the main body device, through the side wall opening and into the native side branch vessel. The side branch device can then be deployed to engage the main body device and the native side branch vessel.

  • Patent number: 9623603
    Abstract: A conduit, such as an introducer sheath, catheter, or guide catheter, incorporating two or more separate lumens to prevent the entanglement of guidewires located at least partially within the conduit. The lumens are separated by at least one disruptable barrier that allows multiple lumens to be converted into fewer lumens prior to or as a device is advanced through the introducer sheath.

  • Patent number: 8845675
    Abstract: The present invention is a catheter device that includes a disruptable guidewire channel. The guidewire channel is configured to provide necessary trackability of the catheter along the guidewire during introduction of the catheter to a treatment site. Once treatment is completed, the guidewire channel can then be disrupted so as to free the guidewire from the catheter in situ. The apparatus of the present invention provides distinct advantages over existing over-the-wire and rapid exchange catheter introduction methods, including the ability to achieve much faster treatment implement exchanges, the ability to rapidly deliver multiple treatment implements in series, and the ability to maintain multiple treatment implements simultaneously at a treatment site using a single guidewire.

  • Patent number: 8197464
    Abstract: A deflecting guide catheter for use in minimally invasive medical procedures such as the treatment of mitral valve regurgitation by reshaping the mitral valve annulus using one or more plications of annular or adjacent tissue each fixed by a retainer is described. The catheter includes an elongated tubular portion having various durometers along its length and at least one puller wire attached to an anchor band near the distal end.

  • Publication number: 20090281612
    Abstract: A balloon catheter and stent delivery system for medical treatment of a patient includes a balloon having a pattern of ridges in an initial deflated state. The ridges may cooperate with structural elements of a stent crimped onto the balloon, to increase and enhance longitudinal retention of the stent while the catheter system is advanced or withdrawn. Upon inflation, the balloon recovers to an inflated shape having a cylindrical working portion. The balloon catheter thus provides for uniform expansion of the stent when the balloon is inflated. The present invention also tends to protect the leading or distal end of the stent during advancement, and tends to protect the leading or distal end of the stent during advancement, and tends to protect the proximal end of the stent during any withdrawal of the catheter system.
