  • Patent number: 10272231
    Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system. The access route is through the inferior vena cava to the right atrium, where a trans-septal puncture, followed by advancement of the catheter is completed. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement through the atrial septum into the left atrium. The distal end of the sheath is expanded using a radial dilator. In one application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as electrophysiological mapping of the heart, radio-frequency ablation of left atrial tissue, placement of atrial implants, valve repair, or the like.

  • Patent number: 9433766
    Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, small cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the femoral arteries and the iliac arteries into the aorta. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is subsequently expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters.

  • Patent number: 9044577
    Abstract: Disclosed is an expandable percutaneous sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion to a second, enlarged cross-sectional configuration. The sheath is maintained in the first, low cross-sectional configuration by a removable tubular restraint or by structural elements built into the wall of the expandable portion of the sheath. In one application, the sheath is utilized to introduce a formed in place orthopedic fixation rod such as for use in spinal fixation procedures, preparation of a spinal segment, or placement of a vertebral body spacer. The sheath can further comprise structural elements to permit re-collapse of the sheath under fluid pressure following completion of the procedure and prior to removal from the patient.

  • Patent number: 8728153
    Abstract: The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the ventricular myocardium, more specifically at the left ventricular apex, into the aortic root. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is subsequently expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters. In an exemplary application, the sheath includes a supported proximal end, a supported distal end, and a collapsible center section. Certain configurations of the sheath are capable of being inserted in a first, small cross-sectional configuration, being expanded diametrically to a second, larger cross-sectional configuration, and then being reduced to a diametrically small size for removal.

  • Patent number: 6108907
    Abstract: A method of assembling a work machine, such as a skid steer loader, includes manufacturing a lower frame assembly with a pair of laterally spaced side rails which extend along the entire length of the lower frame assembly and a pair of spaced engine mounts distanced from the side rails. Then, manufacturing an upper frame assembly with a pair of laterally spaced side members which extend along the entire length of the upper frame assembly. A rear end portion of an engine is then mounted to the pair of engine mounts. The upper frame assembly is then mounted to the lower frame assembly by connecting the respective side members exclusively to the respective side rails to define a main frame assembly. A bumper assembly is then mounted to the main frame assembly through a connection with the lower frame assembly and includes an engine stabilizer. Finally, a front end portion of the engine is then connected to the bumper assembly at the engine stabilizer.
