Abstract: Intravascular delivery systems, devices, and methods are disclosed herein. A representative delivery device can include an inner shaft defining a lumen extending along a length of the delivery device, an outer shaft surrounding the inner shaft along at least a portion of the length of the delivery device, and a tip portion distal to the outer shaft. The inner shaft can include a recess configured to receive a self-expandable implant. The outer shaft can be retractable relative to the inner shaft, and can include a functional member that provides increased tensile strength to the outer shaft, and a coil. The tip portion can extend to a distal terminus of the delivery device and include a cross-sectional dimension that tapers in a distal direction.

Abstract: A device for deploying an implant in a patient's body comprises an elongate delivery tube having an inner element comprising an imaging head, an intermediate element comprising implant retainer formations and an outer element comprising an outer sheath, the inner and outer elements being retractable relative to the intermediate element. A handle at a proximal end of the delivery tube contains a hub assembly comprising hubs of the inner element, the intermediate element and the outer element. A hub carriage that is movable longitudinally within the handle with respect to the intermediate element hub supports the hubs of the inner element hub and the outer element for movement with the hub carriage to retract the inner and outer elements relative to the intermediate element.

Abstract: A pusher assembly for a stent delivery device includes a distal end of an elongate member and a stent-engaging member having proximal and distal ends. The proximal end of the stent-engaging member is mechanically coupled to the distal end of the inner member by a connector, or the proximal end of the stent-engaging member is at least partially inside the distal end of the elongate inner member. The stent-engaging member includes a portion that radially outwardly extends towards the distal end of the stent-engaging member, or the stent-engaging member includes a portion that radially outwardly extends towards the distal end of the stent-engaging member. The stent-engaging member is configured to move a stent when distally advanced and configured to not move a stent when proximally retracted. A stent delivery device includes an elongate outer member, an elongate inner member coaxially positioned within the outer member, and the pusher assembly.

Abstract: A medical device (100), comprising: a stent graft (110), defined thereon with an opening (111); a catheter (120), configured to be partially arranged inside the stent graft (110); and a restraint member (130), configured to apply a radial compression force to the stent graft (110), so as to radially compress the stent graft (110) into a compressed configuration; the medical device (100) is configured so that the opening (111) is in positional correspondence with a distal end of the catheter (120) when the stent graft (110) is in the compressed configuration; the distal end refers to an end that first enters a body of a patient during use of the medical device (100). The medical device (100) can be used for the treatment for vascular lesions involving the aortic arch, which is favorable for establishing access in the branch vessel and shortening the operation duration.

Abstract: A hand-held device is used to deliver and hydrate a temporary polymeric implant having a length, an outer surface and a cross-section, with a disruptable cover over the implant. A lumen may pass through the entire length, the lumen having a surface forming an equivalent diameter in the polymeric stent. The temporary polymeric implant includes a first aqueous-swellable, biocompatible and biodegradable composition (e.g., polymer) having a thickness. The aqueous-swellable and biodegradable polymer retaining structural integrity for at least 1 hours up to thirty days when swollen and kept moist by a moist aqueous environment. Barrier layers of biodegradable polymer(s) may be used to prevent migration of liquids into the lumen.

Abstract: Delivery systems for expandable and stented implants include adjustable tensioning members that control the expansion of the implant along the length of the implant. The tensioning members are wound onto one or more rotors located on the distal segment of the delivery system, which are rotated to unwind the tensioning members and incrementally expand the implant. Positioning mechanisms are also provided to adjust the position and orientation of the implant during delivery.

Abstract: A hybrid graft and method for implantation in a blood vessel of a patient is described. The hybrid graft may include a graft portion having proximal and distal ends and an expandable mesh secured to the distal end of the graft portion. The expandable mesh is configured to transition from an insertion to a deployed diameter. The hybrid graft may also include a tubular sleeve having a lumen configured to receive a part of the graft portion and the expandable mesh and a suture cuff positioned adjacent the expandable mesh. During deployment, the distal end of the hybrid graft is inserted through an opening in the blood vessel wall or an end of the vascular graft and expanded from the insertion to the deployed diameter to secure the hybrid graft within the blood vessel or vascular graft. The suture cuff is sutured to the blood vessel or vascular graft.

Abstract: The invention provides a stent loading system and a method using the same for loading a stent into a sheath. The stent includes a stent body, and an outer periphery of one end of the stent body is provided with a hook. The stent loading system includes a hook straightener for straightening the hook on the stent and a compressor, wherein the stent in which the hook is straightened is reduced in diameter and crimped through the compressor, and the stent crimped is delivered into a preloaded tube; the stent is connected with a delivery system penetrating in the sheath, and the stent in the preloaded tube is delivered into the sheath under the traction of the delivery system.

Abstract: Methods, apparatuses and systems are described for deploying a stent into a body lumen. A stent delivery system may include a sheath with a partially-tubular first portion made from a first material and a second portion made from a second material that is adhered to the first portion to form a tubular body. In some cases, the first material may be chemically incompatible with the second material such that the adhesion between the first portion and second portion is free from cross-linked bonds. The stent delivery system may further include a guidewire lumen with a distal tip that may be slidably disposed within the sheath and a tubular stent disposed between the guidewire lumen and an inside surface of the sheath. The sheath may be formed by coextruding the first material and the second material to form a striped tubular body of the sheath.

Abstract: Devices, systems, and methods for delivering and deploying an implantable medical device with respect to a target site along a tissue wall by applying suction to draw the tissue wall to a delivery and deployment device, such as to a tissue-penetrating end of the delivery and deployment device. An additional implantable device may be deployed distal to the tissue wall, such as to facilitate manipulation of the distal wall. At least a portion of the first implantable medical device may be deployed with respect to the additional implantable medical device, such as within a lumen of the additional implantable medical device. The implantable medical device may shift from a delivery configuration to an expanded deployed configuration, and at least a portion of the implantable medical device may expand beyond the deployed configuration after deployment device to further resist migration of the implantable medical device from the target site.
