A conveyor and a lumen apparatus delivery system. The conveyor includes a sheath core tube, a delivery sheath and an operating handle. The proximal end of the sheath core tube and the proximal end of the delivery sheath are both connected to the operating handle. The delivery sheath and the sheath core tube are both a hollow tube. The delivery sheath is sleeved on the sheath core tube in an axially slidable manner, and the delivery sheath and the sheath core tube cooperatively define a storable cavity. The delivery sheath includes a loading portion, a pushing portion and a connecting portion. The proximal end of the loading portion is connected to the distal end of the pushing portion; the proximal end of the pushing portion is connected to the distal end of the connecting portion, and the proximal end of the connecting portion is connected to the operating handle.

A handle for a catheter having an inner shaft and a retractable shaft. The handle includes a housing, a pull cable and a release button mounted movably on the housing. A sleeve is secured in the housing and a brake hose is guided movably in the longitudinal direction in a continuous opening of the sleeve. The brake hose has a first continuous opening for arrangement of the pull cable and a second continuous opening for arrangement of the inner shaft. The brake hose configured and arranged such that its position relative to the sleeve in a first state is fixed by the release button, and such that the brake hose in a second state is displaceable after actuation of the release button together with the pull cable in the longitudinal direction of the sleeve and relative to the sleeve and the inner shaft in the proximal direction in order to retract the retractable shaft, such that the retractable shaft can be connected to the pull cable.

A delivery system for delivering and deploying stent grafts having a proximal stent includes a first lumen and a stent capture device including a capture portion fixedly connected adjacent a first lumen distal end. An outer catheter has a catheter distal end and a catheter inner diameter. A second lumen having a second distal end is slidably disposed about the first lumen and within the outer catheter. A stent graft sheath has a sheath proximal end connected to the second distal end and disposed about the first lumen. The sheath has a sheath distal end and a sheath inner diameter greater than the catheter inner diameter for holding a compressed stent graft. A distal nose cone has a cone proximal end connected to either the capture portion or the first distal end. The nose cone and the capture portion are movably adjustable to selectively capture the sheath distal end therebetween.

The expandable sheaths disclosed herein include an elastic outer tubular layer and a multisegmented inner tubular layer that includes at least two coextruded segments having different durometers and different coefficients of friction. The inner tubular layer further includes a thick wall portion integrally connected to a thin wall portion. The thin wall portion has a lower durometer than the thick wall portion. The thick wall portion has a first and second longitudinally extending end, and the thin wall portion extends between the first and second longitudinally extending ends. The elastic outer tubular layer and the inner tubular layer are radially movable between a non-expanded state, where the elastic outer tubular layer urges the first longitudinally extending end under the second longitudinally extending end, and an expanded state, where the first and second longitudinally extending ends of the inner tubular layer expand apart with the thin wall portion extending therebetween.

A delivery guide wire (10,100) and a therapeutic device are disclosed. The therapeutic device includes the delivery guide wire (10, 100), a medical implant and a delivery catheter (20). The delivery guide wire (10, 100) includes a core shaft (110) and a driving member (120) disposed on the core shaft (110), and the driving member (120) defines thereon a depression. The medical implant is compressed by the delivery catheter (20) and disposed over the delivery guide wire (10,100) in such a manner that it is at least partially received in the depression. This results in an increased contact area between the medical implant and the delivery guide wire (10, 100), which facilitates movement of the medical implant in sync with the delivery guide wire (10, 100) and makes its delivery easier.

Aspects of the present invention relate to a delivery device for locating an expandable implant for treating BPH within the prostatic urethra of a patient. The delivery device comprises an inner tube and an outer sleeve movable relative to the inner tube between a stored position and a deployed position. The outer sleeve surrounds the inner tube to define an annulus therebetween and the expandable implant is retained within the annulus when the outer sleeve is in the stored position.

Disclosed is a false lumen closure assembly for closing a false lumen in a body vessel including a compressed false lumen occluder, a carrier catheter and a retractable sheath. The compressed false lumen occluder includes a stent graft including at least one occlusive barrier across the stent graft to occlude blood flow through an interior of the stent graft. The carrier catheter carries the false lumen occluder and extends from a proximal end proximal of the false lumen occluder to a distal end distal of the false lumen occluder, and passes the false lumen occluder exteriorly of the stent graft. The compressed false lumen occluder and at least part of the carrier catheter are disposed in a lumen of the retractable sheath.
