An aortic bare stent and an aortic dissection stent are disclosed. The aortic bare stent is in a tubular net structure, with multiple support stents in circles and arranged along an axial direction. Two adjacent support stents are connected by a connector stent. The connector stent is made of a hyper-elastic material. A flexural rigidity of the connector stent is less than that of the support stent. The support stent is made of a single-strand hyper-elastic nickel titanium wire or formed by cutting a nickel titanium tubing. The connector stent is made of a multi-strand composite wire. The multi-strand composite wire is formed by twisting or weaving multiple strands of filaments, and each strand of filament is independently of a nickel titanium material.

A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

An endoluminal device can be configured for precise positioning during deployment within a vessel. The endoluminal device can be a tack, stent, vascular implant or other type of implant. The endoluminal device can have circumferential member with an undulating configuration having multiple inward and outward apexes and struts extending therebetween. Two of the struts can be used to establish a foot for the precise positioning of the device during deployment. A method of placing the endoluminal device can include withdrawing an outer sheath such that a portion of the endoluminal device is expanded prior to the rest of the endoluminal device.

A self-closing device for implantation within a patient's body includes base material including an inner surface area for securing the base material to a tissue structure, and a plurality of support elements surrounding or embedded in the base material. The support elements are separable to accommodate creating an opening through the base material for receiving one or more instruments through the base material, and biased to return towards a relaxed state for self-closing the opening after removing the one or more instruments. The device may be provided as a patch, cuff, or integrally attached to a tubular graft or in various shapes.

An endoprosthesis constraining sleeve includes a single sheet of material forming at least two folds, and a common bond line constraining the single sheet of material to maintain the at least two folds and to form at least two discrete lumens. A first lumen of the at least two lumens is configured to receive a constrained endoprosthesis therein. A second lumen of the at least two lumens is configured to receive a control feature therethrough.
