  • Patent number: 9522073
    Abstract: An endovascular stent graft delivery device has portion to remain outside a patient in use and a proximal portion to be introduced into a patient. The proximal portion has a dilator at the proximal end and a length extending module is fastened to the dilator and extends proximally. The length extending module has a proximal end which in use extends out of the patient. The dilator has a dilator marker and the length extending module has a first and second marker at the distal and proximal ends of the length extending module. The first marker and the second marker are at the same relative circumferential position on the length extending module so that the rotational position of the elongate body within the patient can be determined.

  • Publication number: 20080046065
    Abstract: A leg extension (10) for a stent grafting system to connect between an aortic graft and an iliac graft. The leg extension is a tubular body (12) of a biocompatible graft material with self-expanding stents connected along the length of the tubular body and the tubular body having a distal end with a connection region. The connection region has a flared stent defining an external frusto-conical surface to provide a connection arrangement to engage within an internally flared portion of an iliac graft.

  • Publication number: 20070255390
    Abstract: A stent graft introducer actuation assembly (1) having a fixed handle (3) and at least one sliding handle (5, 7), the sliding handle or handles telescoping within the fixed handle, and a winch arrangement (9) to retract the sliding handle into the fixed handle. There may be provided arrangements to give a mechanical advantage to the winch arrangement.

  • Publication number: 20070239141
    Abstract: A medical grasping device (1) has an elongate control member (9) with a grasping member (17) proximal to its distal tip. An outer sheath (3) with a passageway therethrough surrounds the elongate control member and is relatively movable with respect to the control member. A control assembly (2) disposed at a proximal end of said outer sheath has a fixed handle (5) and a sliding handle (7) and the proximal end of the elongate control member is fixed to the sliding handle to move the control member. The grasping member (17) has a plurality of pre-formed wire loops (50, 52, 54, 56) which self-deploy transversely upon emerging from said distal end of said outer sheath. Each wire loop is fastened to substantially opposite sides of the elongate control member so that each of said wire loops is substantially semi-circular upon full deployment and the respective ends (27, 29) of each wire loop extend substantially in opposite directions from the elongate control member.

  • Publication number: 20070219621
    Abstract: A stent graft (10) has a tubular body (12) of a biocompatible material and at least one fenestration (18, 20). The or each fenestration has a tubular side branch stitched into it with a portion of the tubular side branch extending within the tubular body and a portion of the tubular side branch extending exteriorly of the tubular body. The stitching by which the tubular side branch is mounted into the fenestration extends circumferentially and diagonally from one end of the tubular side branch to the other such that the tubular side branch extends from the tubular body at an angle thereto. The tubular side branch has a resilient ring around at least one and preferably both ends thereof and a self expanding stent in between them. The tubular side branch can have a circumferential linear portion (46) at an inner end to engage against the inner wall (58) of the tubular body.
