A device is provided for piercing a graft and artery wall in order to retain the graft on the artery. The device has a central section with an abutment surface for contacting the inner wall of the graft and two elongate members with distal ends for contacting the outer wall of the artery when the device is pierced through the graft and artery. The elongate members are biased so as to urge the abutment surface into the graft and retain the graft on the artery.

Device for the repair of arteries

A control mechanism comprises an elongate handlehaving an external threadand a barrelwith internally projecting pinsthreaded over handle. Rotation of barrelcauses handleto move back and forth along its longitudinal axis to retract and advance a catheter sheath to which handleis coupled, thereby enabling an implant to be deployed by the catheter. Rotation movement of barreland longitudinal movement of handlecan be disassociated to enable speedy retraction or advancement of the catheter sheath.

Control device for medical catheters

A sewing machine is provided which is capable of sewing reinforcing wire to tubular grafts in order to form stent grafts. A bobbin (which may be seated in a shuttle) carries a bottom thread through the bore of the tubular graft and forms a stitch in combination with a top thread carried on a needle which pierces the graft wall.

Method for manufacturing stent-grafts

A stent for occluding the human ductus arteriosus comprises a length of wire of shape memory effect or superelastic material which is expandable from a relatively straightened state for introduction into the patient to an occluding state wherein the wire defines an occluding anchor part and a spiral anchor part and a straight linking part connecting the two wherein the wire has a series of turns extending over the cross-sectional area of the occluding anchor part.

Surgical implants and delivery systems therefor

A method for stitching thread onto the wall of a tubular medical implant (preferably a graft) employs a sewing machine with an elongate bobbin or a needle on an elongate element, depending on whether it is desired to sew from the outside-in or the inside-out. A motor rotates and translates the implant, which is mounted on a hollow drum, relative to the needle.

Method for manufacturing a medical implant

A graft is provided with a flexible sheet of graft material to which is sewn a reinforcing wire, preferably of shape-memory alloy. Sewing of the wire is carried out while the sheet is substantially planar, thus by conventional embroidery machines. The sheet is subsequently rolled into a tubular shape.

Reinforced graft

A tubular graft/stent comprises a tubular sheath having at intervals along its length a plurality of ring-like rigid members, which are attached to the sheath around their respective circumferences and are made of a shape memory material, so that when the members change shape the sheath adopts a new cross section in conformity with the members along the sheath's whole length. The members may be discontinuous to allow the adoption of a contracted shape in the martensitic phase and an expanded shape in the austenitic phase. A graft may also have a branched side tube which can be inverted so as to be housed within the sheath.

Method of producing a surgical implant

An occlusion device comprising an occluding barrier, anchor means and means for retaining orientation. Preferred embodiments comprise means for urging the anchor means into position.
