  • Publication number: 20200022830
    Abstract: There is described an endovascular prosthesis delivery device. The subject endovascular prosthesis delivery device comprises a combination of a delivery frame element and a hub insert element that are secured to one another by a first retention element. At a distal portion of the delivery frame element, there is a prosthesis attachment zone for coupling to an endovascular prosthesis. When it is desired to deploy the endovascular prosthesis, the first retention element is broken in a manner to allow relative movement between the hub insert element and the delivery frame element. A pull wire assembly is secured with respect to the hub insert element and comprises a pull wire which is coupled to the endovascular prosthesis in the prosthesis attachment zone of the delivery frame element.

  • Patent number: 10278840
    Abstract: There is disclosed a novel endovascular prosthesis that has an improved rotational range of proper placement of the prosthesis with respect to the opening of the aneurysm and provides improved flexibility with respect to longitudinal positioning of the device in the artery. This provides the clinician with a significant advantage over the prior art devices described above. The present elongate endovascular prosthesis comprises a first expandable portion expandable from a first, unexpanded state to a second, expanded state to urge the first expandable portion against the wall of the vascular lumen such as an artery. The endovascular prosthesis further comprises a retractable leaf portion attached to the first expandable portion; the retractable leaf portion serves to facilitate stasis and thrombotic occlusion of the aneurysm. The retractable leaf portion comprises at least one spine portion and a plurality of rib portions attached to the spine portion.

  • Patent number: 9345598
    Abstract: In one of its aspects, the present invention relates to an endovascular prosthesis. The endovascular prosthesis comprises a first expandable portion expandable from a first, unexpanded state to a second, expanded state to urge the first expandable portion against a vascular lumen and a retractable leaf portion attached to the first expandable portion. The retractable leaf portion comprises at least one spine portion and a plurality of rib portions attached to the spine portion. Longitudinally adjacent pairs of rib portions are free of interconnecting struts. The endovascular prosthesis that can be unsheathed and re-sheathed for repositioning of the endovascular prosthesis prior to final deployment thereof. There is also described a delivery device that that is particularly well suited to delivering the present endovascular prosthesis through tortuous vasculature in the body.

  • Publication number: 20150313737
    Abstract: The present invention relates to an endovascular prosthesis. The endovascular prosthesis comprises a first expandable portion expandable from a first, unexpanded state to a second, expanded state to urge the first expandable portion against a vascular lumen and a retractable leaf portion attached to the first expandable portion. The retractable leaf portion comprises at least one spine portion and a plurality of rib portions attached to the spine portion. In one preferred embodiment of the present endovascular prosthesis, the retractable leaf portion is configured such that a pair of ribs attached on opposite sides of a longitudinally straightened configuration of the spine portion in a plane of view normal to a central axis of the prosthesis defines a shape, in two dimensions, that is substantially non-circular.
