The present disclosure relates to a stent delivery component, a stent delivery system and a stent system. In particular, a stent delivery component including a base and at least two clamping wings which are rotatably connected with the base, respectively, is provided. In one aspect, the stent delivery component can effectively enclose the stent to complete delivery. In another aspect, the stent delivery component is kept in line contact with an inner wall of a delivery catheter to reduce the contact area, thereby reducing the frictional resistance and being beneficial to reduce the operation difficulty and increasing the delivery efficiency.

An endoluminal prosthesis introducer may include an elongate tubular sheath including a reinforced longitudinal segment and a peelable longitudinal segment extending distally from the reinforced segment. An elongate tubular cannula may be disposed within the sheath. Upon application of a force applied to a distal end of the sheath, the peelable segment may progressively split in a proximal direction, and the reinforced segment may longitudinally move relative to the cannula in a distal direction.

The present application discloses a covered stent and a method for navigating the covered stent to a branch vessel, the covered stent including a main body and at least one lateral side branch connected to the main body. A system of covered stents and a method for implanting, including interconnecting the covered stents is also disclosed.

A delivery system and method for implanting a stent graft includes a flexible sheath that defines loops distributed longitudinally and wherein substantial alignment of the loops along a longitudinal axis of a guidewire catheter radially constrict the flexible sheath. The flexible sheath defines longitudinal edges that at least partially form a seem when the openings are aligned, whereby, upon alignment, the flexible sheath defines at least one fenestration in the luminal configuration of the flexible sheath. A ligature extends through the openings of the flexible sheath and causes the openings to be substantially aligned, thereby constraining the flexible sheath. The ligature is proximally retractable from the openings to thereby release the flexible sheath from a radially constricted configuration.

The present disclosure includes an expandable medical device and outer sheath combination. The outer sheath is capable of being split to form multiple sheath sections that may be peeled back to expose a portion or all of the expandable medical device. The medical device, as well as the outer sheath, may include one or more therapeutic agents for delivery to a treatment area within a patient.

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.
