Abstract: An introducer assembly includes an introducer element (80), which may have a catheter or sheath (82), a pusher element (84) holding an implantable medical device (88) and a dilator tip (90). The assembly also includes a protective sleeve (72) within which the introducer element (80) is disposed. The protective sleeve (72) is made of an absorbable hydrophilic material which is deployed in a wetted condition and acts as a cushion or barrier between the introducer element (80) and the vessel wall (60). The sleeve can prevent trauma to the vessel during the deployment of the introducer element (80) and as a result can avoid vessel spasm which can occur in delicate vessels such as the cerebral vessels. The introducer assembly may be used for cerebral applications.

Abstract: Methods of reducing air within a stent graft delivery device are disclosed, utilizing various flushing techniques. A port in a manifold that includes a pusher catheter coaxially disposed about a guide wire catheter is flushed. A portion in a sheath hub that excludes a longitudinally extended outer sheath coaxially disposed about the pusher catheter is flushed with a flushing fluid and/or a blood soluble gas, such as carbon dioxide. The guide wire catheter is also flushed.

Abstract: A system for deploying a stent graft includes a stent graft. The stent graft has a tubular structure and includes first and second end stents and at least one stent between the first and second end stents. The system also includes a plurality of constraining mechanisms arranged along the length of the stent graft constraining the stents of the stent graft, and an actuation mechanism configured to release the plurality of constraining mechanisms in order from the first end to the second end of the stent graft and circumferentially sequentially from about the stents.

Abstract: An endoluminal graft includes a tubular graft material having a closed sleeve integral with the tubular graft material. The closed sleeve extends a distance along the tubular graft material. A length of wire extends at least partially along the distance and is enclosed by the sleeve. The tubular graft material and the sleeve may comprise a single piece of graft material. The sleeve may be a closed circumferential sleeve and/or a closed longitudinal sleeve.

Abstract: A stent graft for deployment in a curved lumen such as the aortic or thoracic arch comprises a constraining mechanism at its proximal end. A stent provided at the proximal end of the stent graft includes loops of material that co-operate with restraining wires that extend between a central guide wire carrier and a restraining wire cannula. The constraining mechanism acts to maintain the proximal stent constrained at both the proximal and distal ends of the proximal stent. The proximal stent is thus allowed to expand after expansion of the remainder of the stent graft during deployment. In an embodiment, the constraining mechanism acts to constrain two adjacent struts of the proximal stent at three points radially therearound, at the proximal end of the stent and at the distal end of the stent. The proximal stent may then overlap with the interior of an adjacent stent at an inner part of a curved vessel.

Abstract: An introducer assembly includes a distal sheath and a proximal sheath. A splitting element is located at a proximal end of the distal sheath and is arranged to split the distal sheath in a distal direction, so as to deploy first a branch element of a medical device and thereafter the distal end of the medical device. The proximal sheath can then be retracted to release the proximal end of the medical device. Deployment of the medical device from the branch element first enables accurate positioning of the branch element prior to deployment of the main body portion of the medical device.

Abstract: An implantable medical device includes a support structure which is twistable in a longitudinal direction of the device. A sleeve of filter or occluding material is attached to the ends of the structure. The structure in practice twists on itself in the longitudinal direction, causing the sleeve to twist on itself and as a result to close the lumen through the sleeve. The device provides reliable closure and as a result occlusion of a vessel. It is also able to be delivered over a guide wire. In another embodiment, the support structure includes a wire which coils around the sleeve to constrict the sleeve and as a result to close a lumen of the sleeve.

Abstract: A delivery system for an occlusion balloon includes a delivery catheter and a balloon releasably detached thereto. The balloon can include a base portion that is threaded onto the end of the delivery catheter. The balloon can include a one-way valve or septum in the base portion, through which a filling needle is inserted into a cavity of the balloon. The balloon can be filled with a fluid to expand the balloon and fix the balloon within the patient's body. The balloon can be filled with a hardening material to assist in fixing the balloon in place and occluding the blood vessel. The balloon can include anchoring structure on its outer surface to assist in the fixing the location of the balloon. The delivery device and needle can be detached and withdrawn from the balloon, allowing the septum to close and seal the balloon, leaving the balloon fixed within the body vessel.

Abstract: An implant release mechanism for releasing, for example, a stent (60) is provided with three restraining wires (62) which pass in the space between a wire guide catheter (24) and a pusher sheath or dilator (30) and are arranged substantially equi-angularly threrearound. Each restraining wire (62) holds both the proximal and distal ends of the stent (60), in this case each holding a proportion of the ends of the stent (60). When the restraining wires (62) are pulled they will first unwrap from the proximal end of the stent (60) and will then release the distal end of the stent (60) so as to allow the stent to become fully deployed within the lumen of the patient. The use of common release wires improves deployment of implants and reduces the number and volume of components in the device, thereby allowing it to occupy a smaller volume.
