Abstract: An aortic graft device (10) is provided with a graft portion (12) integrally fixed to a corrugated trunk portion (14). A fixing ring (16) is provided between the graft and trunk portions. The trunk portion (14) can be averted into the graft portion, leaving the fixing ring (16) at an extremity of the device for suturing purposes. The fixing ring (16) is preferably made from a relatively stiff material such as a compressed foam or rubber like material, which provides a relatively solid component for a surgeon to hold during suturing and which can provide a strong support for sutures.

Abstract: An occlusion device (30) includes at least one self-expanding frame (42, 44) and graft material (46). Occlusion occurs by constricting the graft material (46) at a substantially central point or at an end of the device. The constriction is sized such that a guide wire (34) is able to pass therethrough. A valve mechanism (50) includes a screen (52) made from a resilient material and which includes a closable opening (54). The valve mechanism (50) allows a guide wire to pass through the occlusion device (30) while an effective physical barrier is maintained after removal of the guide wire (34).

Abstract: An introducer assembly provided with a sheath formed of a plurality of elongate sections which are coupled to one another along their longitudinal sides by a dovetail coupling. The sheath sections are slidable longitudinally relative to one another, enabling the sheath to be retracted in stages. This reduces the amount of friction which must be overcome in the use of the sheath and in particular during the deployment of a medical device carried within the sheath. The structure can also substantially increase the precision of deployment of the medical device, as well as decreasing the force required during the deployment operation.

Abstract: A delivery assembly (10) for an implant (30) includes a release mechanism with a locking element (52) and a blocking member (56). The locking element (52) includes a latching pin (14) that engages with an eyelet (54) in the implant (30) to attach the implant (30) to a distal end of an inner catheter (36). The blocking member (56) prevents premature disengagement of the latching pin (14) from the implant (30). Withdrawal of the blocking member (56) allows disengagement of the latching pin (14). The locking pin (52) and the blocking member (56) extend along the lumen of the inner catheter (36) from a handle (12) such that a guide wire (34) is also able to extend through the lumen of the inner catheter (36). The locking pin (52) and the blocking member (56) preferably have a crescent-shaped transverse cross section. The release mechanism allows retrieval of the implant (30).

Abstract: A coupling device is formed of a double tubing of a substantially non-porous membrane material, typically a conventional graft material, that is of inner and outer layers of membrane material. The inner and outer layers are coupled by bridging rings which allow the layers to be spaced from one another in use. Attached to the inner and outer layers are first and second stents. The stent is located on the inside of the double tubing, while the stent is located on the outside of the double tubing. The device can expand in effect to ‘bulge’ and thus to fill the gaps to the vessel wall and to the stent-graft sections. The device can provide reliable coupling of stent-grafts in vessels of varying diameter or in vessels inflicted with one or more aneurysms.

Abstract: A coupling device (28) is formed of a double tubing (50) of a substantially non-porous membrane material, typically a conventional graft material, that is of inner and outer layers of membrane material (52, 54). The inner and outer layers (52, 54) are coupled by bridging rings (56, 58) which allow the layers (52, 54) to be spaced from one another in use. Attached to the inner and outer layers (52, 54) are first and second stents (60, 62). The stent (60) is located on the inside of the double tubing, while the stent (62) is located on the outside of the double tubing (50). The device (28) can expand in effect to ‘bulge’ and thus to fill the gaps to the vessel wall and to the stent-graft sections (24, 26). The device can provide reliable coupling of stent-grafts in vessels of varying diameter or in vessels inflicted with one or more aneurysms.

Abstract: There is disclosed a drug eluting balloon catheter assembly provided with a balloon formed of an inner balloon member of non-compliant material and an outer balloon member of a compliant material and which is provided with holes therein for eluting a drug or other fluid. In use, the outer balloon member is biased by contraction onto the inner balloon member thereby keeping the holes therein normally sealed closed and minimizing dead space in the device.

The locking element (52) includes a latching pin (14) that engages with an eyelet (54) in the implant (30) to attach the implant (30) to a distal end of an inner catheter (36) of the deployment of the delivery assembly (10). The blocking member (56) prevents premature disengagement of the latching pin (14) from the implant (30). Withdrawal of the blocking member (56) allows disengagement of the latching pin (14) once the implant (30) has been correctly positioned within a patient's vasculature. The locking pin (52) and the blocking member (56) extend along the lumen of the inner catheter (36) from a handle (12) at the proximal end thereof, and are arranged such that a guide wire (34) is also able to extend through the lumen of the inner catheter (36). The locking pin (52) and the blocking member (56) preferably have a crescent-shaped transverse cross section.

Abstract: A rapid exchange implant deployment catheter includes a relatively stiff hypotube (12) and a relatively flexible distal tube (14). A side port (15) for a guide wire is provided towards the distal end of a transition zone (16) between the hypotube (12) and the distal tube (14). The distal end of the hypotube (12) is laser cut to form a plurality of slits (18) between which are formed a plurality of projections (11, 11?). At least one of the projections (11?) extends into the distal tube 14 to a point beyond the position of the side port (15).
