A medical implant delivery system is described. The system can be used to deliver a variety of implants including stents and/or stent grafts. The delivery system retains the implant during delivery and detaches the implant at a target location.

Provided is a medical tubular body delivering device that can prevent kinking and efficiently deploy a medical tubular body, while maintaining the reinforcing effect without reducing operability. The device has an outer tube through which the medical tubular body is disposed; a guidewire insertion member provided proximal to the medical tubular body; and an inner insertion member provided in the outer tube, and the guidewire insertion member has a penetration passage; a guidewire tube is provided in the penetration passage; the inner insertion member is partially fixed to the guidewire insertion member; a first protection member is provided outside a part of the inner insertion member proximal to a fixing portion; and at least a part of the inner insertion member between a proximal end of the fixing portion and a distal end of a region where the first protection member is provided is covered by a second protection member.

A vascular prosthesis for implantation at an aortic arch of a human patient includes major tubular component defining a longitudinal axis and an island graft that has a length parallel to the longitudinal axis that is greater than a width transverse to the longitudinal axis. The vascular prosthesis delivery system includes a vascular prosthesis of the invention. The vascular prosthesis can also be a hybrid vascular prosthesis, including a proximal surgical segment that can be corrugated, an endovascular stent graft segment extending distally from the surgical segment, and a collar interposed between the surgical segment and the endovascular stent graft segment. The island graft can be pleated or corrugated and can be radially raised from a surface of the major tubular component.

A venous valve prosthetic implant for treatment of venous disease may include an expandable anchoring frame, a valve seat attached to the anchoring frame, a ball retention member attached to the anchoring frame, and a ball disposed within the lumen of the anchoring frame, between the valve seat and the ball retention member. The anchoring frame may include a first end, a second end, and a middle valve portion, where the middle valve portion expands to a smaller diameter than a diameter of either the first end or the second end. The ball may move back and forth within the middle valve portion, between a fully open position and a fully closed position.

A catheter assembly for delivery of an expandable implant having at least one branch portal, which utilizes a secondary sleeve for releasably constraining a middle portion of the expandable implant after releasing a primary constraining sleeve used for constraining the expandable implant toward a delivery configuration for endoluminal delivery; and methods of using the same.

A stent graft delivery system. The system includes a stent graft cover having a central longitudinal axis. The stent graft cover houses a first guidewire lumen extending along a first guidewire lumen axis and configured to track along a first guidewire. The first guidewire lumen axis is offset the central longitudinal axis. The stent graft delivery system further includes a tapered tip extending distally from the stent graft cover and defining an offset through-channel extending within the tapered tip along a tapered tip offset axis and configured to track along the first guidewire. The first guidewire lumen axis and the tapered tip offset axis extend along a common axis.

A catheter device for implanting a medical implant includes an actuating element configured to move with a capsule of the catheter device and to be manually operated to bring the actuating element from a first state to a second state. A first and/or second stop is included in the catheter device. The first stop is configured to limit a movement of the actuating element and therewith of the capsule in a first direction, e.g. proximal direction (P), when the actuating element is in the first state. The second stop is configured to limit a movement of the actuating element and therewith of the capsule in a second direction, e.g. distal direction (D), when the actuating element is in the first state, so as to prevent pressing of the capsule against a catheter tip of the catheter device and/or against a capsule stop of the catheter device.

A stent delivery system and a method for mounting a stent (1) are disclosed. The stent delivery system includes a handle, an outer tube (52), a restraining member and delayed-release member (4) and is structurally simple and easy to use. During the release of a stent (1) from the restraining member, a proximal end of the stent (1) is always secured to the delayed-release member (4), avoiding the stent (1) from moving backward under the action of forces from the blood and thus resulting in improved positional accuracy of the release of the stent (1). Additionally, during the release of the stent (1) from the restraining member, a distal end of the stent (1) can be secured to an inner tube (51) by means of a fixed coil (32), and the proximal end of the stent (1) can remain fixed on the delayed-release member (4). This can avoid the stent (1) from moving forward or backward during the release of a middle section of the stent (1), allowing the stent (1) to be released under true accurate positional control.
