  • Patent number: 10279153
    Abstract: A supportive balloon catheter which may be used to assist a wire guide in advancing across a lesion which partially or totally occludes an intraluminal passage. The supportive balloon catheter is advanced over the wire guide, close to the location of the lesion. The supportive balloon catheter is then inflated, securing the position of the wire guide in the intraluminal passage. A braid on the catheter may provide additional structural support. The secured catheter restricts the movement of the wire guide advancing across the lesion, preventing kinking or deflection off the surface of the lesion. Once the wire guide has advanced across the lesion, the supportive balloon catheter or a different angioplasty may be used to clear the lesion from the intraluminal passage.

    Abstract: A stiffenable structure is made of longitudinal beams that are positioned around a longitudinal axis. In one state, the longitudinal beams are bendable so that the structure is bendable. As the structure bends, the longitudinal beams slide longitudinally with reference to one another.

In some aspects the longitudinal beams are made of two or more longitudinal laminar elements. As each beam bends, the laminar elements slide longitudinally with reference to one another. Each beam, and accordingly the structure, is stiffened by preventing the laminar elements from sliding longitudinally relative to one another.

The first characteristic is that the surgical drain/catheter can be bent without causing any fold/crease to its outer and inner surfaces. The second characteristic prevents internal occlusions while the drain/catheter is bent.

  • Publication number: 20140276642
    Abstract: Apparatus and methods for an endovascular catheter that can be inserted within tortuous body anatomies and then selectively stiffened and fixed in place. In a particular embodiment, this stiffness is reversible. The stiffness or a comparable mechanical characteristic of the catheter assembly may be adjusted to a relatively low value during insertion (so that it easily navigates a guide wire or the like), and then subsequently adjusted to a relatively high value in situ to keep the catheter assembly substantially fixed in place (i.e., during delivery of an interventional device).

  • Publication number: 20140249510
    Abstract: A flexible, steerable intravascular catheter includes an elongate flexible shaft having a heterogeneous or multi-zone stiffness profile or structure. A first or distal portion of the catheter shaft may have a substantially constant or distinct stiffness or flexibility, a second, intermediate or transition section is proximal relative to, and less flexible than, the first section, and a third section is proximal relative to, and also less more flexible than, the first section. The third section also includes a substantially constant or distinct stiffness or flexibility. The flexibility or stiffness of the second section varies along its length, e.g., in a substantially linear, step-like or ramp-like manner to provide a smooth or gradual transition between the stiffness of the first or distal section and the flexibility or stiffness of the third or proximal section.

  • Publication number: 20140221967
    Abstract: Disclosed herein are devices for minimally invasive vertebral augmentation and restoration of spinal lordosis using a steerable cannula assembly. When deployed, the articulating cannula, including an outer cannula and an inner cannula extending into a central lumen of the outer cannula and coupled to each other at their distal ends, can be manipulated to curve/bend the body of the articulating cannula. This manipulation is used to create a void within the interior body and may also be used to control delivery of a treatment element to the interior body.

  • Patent number: 8790387
    Abstract: Embodiments of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such embodiments can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some embodiments can include a sheath with inner and outer layers, where a folded portion of the inner layer extends through a slit in the outer layer and a portion of the outer layer overlaps the folded portion of the inner layer. Some embodiments include an elastic outer cover positioned outside the outer layer. Embodiments of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.

  • Patent number: RE45380
    Abstract: A coaxial guide catheter to be passed through guide catheter having a first lumen, for use with interventional cardiology devices that are insertable into a branch artery that branches off from a main artery. The coaxial guide catheter is extended through the lumen of the guide catheter and beyond the distal end of the guide catheter and inserted into the branch artery. The device assists in resisting axial and shear forces exerted by an interventional cardiology device passed through the second lumen and beyond the flexible distal tip portion that would otherwise tend to dislodge the guide catheter from the branch artery.
