    摘要: A medical grasping device (10) for vascular use, having an outer sheath (12), an elongate control member (50) extending within an outer sheath (12) to a distal tip section (54), and a proximal control assembly (22) including an actuation section (24) joined to the elongate control member (50). Adjacent to the distal tip section (54) is a grasping portion (70,70′) that is extendable from the outer sheath (12) to create loops (74,74′) for grasping a target object (T) for repositioning within the vascular system, or for removal from the patient, with loops being retractable into the outer sheath to hold the target object against the device (10) during movement of the device. Elongate control member (50) is preferably a cannula or tube having a lumen (58) extending completely therethrough for placement over a guide wire (28) already in the patient.

    摘要: A fenestration (32) for a stent graft (30). The fenestration is an aperture in the biocompatible graft material and has at least one flap (38, 40) of a biocompatible graft material covering the aperture on the inside whereby the flap closes off the aperture but can be displaced to allow access through the fenestration. An array of such fenestrations may be placed on a stent graft to facilitate alignment of a branch vessel with a fenestration. A slip knot (46, 46) which can be released by forcing a dilator between the flaps can be used to hold the flaps together.

    摘要: A deployment system for introducing stent grafts which have a side arm or into which a side arm can be deployed. For instance the stent graft can be deployed into the thoracic arch of a patient. The deployment system including an introducer (1), an auxiliary catheter (13) disposed within the introducer and an auxiliary guide wire (14) disposed within the auxiliary catheter. The auxiliary guide wire extends to adjacent the proximal end (6) of the introducer and can be extended from the proximal end of the introducer so that it can be snared from a side branch artery (56) to assist with deployment of a side arm (23) of the stent graft into the side artery or for the deployment of a side arm stent graft into the stent graft.

    摘要: 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.
