A method, system, or apparatus for stent delivery. Delivering one or more stents with a delivery tool that can include a kinetic transfer of energy to deliver one or more stents. The stents can include a modifiable stent that can change its overall shape and/or dimensions based on pre-configured design parameters. A coil stent that can engage with a vessel that surrounds the modifiable stent forming a dual stent configuration. The coil stent can also include anchor points that allow it to engage with a second vessel securing the first vessel and the second vessel together to aid in the healing process.

A tubular stent formed of at least one wire includes proximal and distal ends and an intermediate part that includes annular windings extending in a circumferential direction around a longitudinal axis of the stent and arranged in a direction along the longitudinal axis. Each of the windings has hill-shaped sections bent toward the proximal end and valley-shaped sections bent toward the distal end, alternately arranged in the circumferential direction. All sections form intersections helically arranged around the longitudinal axis. The hill-shaped sections of one of the windings and the valley-shaped sections of the neighboring winding overlap each other at the intersections in a radial direction of the stent. Distances in the direction of the longitudinal axis between the hill-shaped and the valley-shaped sections of a first winding forming at least one of the proximal and distal ends are different from each other in a circumferential direction of the stent.

A medical device comprises a substrate (10) defining a major surface (9) defining a plane, including a plurality of first struts (14) along a first direction interconnected with a plurality of second struts (12) extending along a second direction not parallel with the first direction, wherein widths (11) of the second struts as measured along the major surface are larger than thicknesses of the second struts as measured perpendicular to the major surface such that when the substrate is stretched in the first direction, intermediate sections (15) of the second struts (12) rotate relative to the first struts (14) and the intermediate sections of the second struts bend out of the plane of the major surface. The medical device is operable to extend and/or retract elements suitable for a particular purpose. The elements are extended and/or retracted in response to a stress applied by way of stretching and/or retracting the device, among other methods. The elements may remain extended and/or retracted or may recoil back to an initial position upon the removal of the force. In various embodiments, the elements are used to treat or deliver treatment to a target site within a body.

Aortic root replacement grafts, systems and methods for implanting an aortic root replacement graft are disclosed. The graft includes a tubular portion; a bulged portion with a first end and a second end, wherein the second end of the bulged portion is coupled to a first end of the tubular portion; a cuff portion coupled to the first end of the bulged portion; and at least one side arm coupled to and extending from the bulged portion. Methods for implanting an aortic root replacement graft with two side arms are also disclosed.

A crimper includes a first arm that includes a first crimper die that defines a first tapered channel. The crimper also includes a second arm coupled to the first arm at a pivot connection. The second arm includes a second crimper die that defines a second tapered channel. The pivot connection enables the first arm and the second arm to rotate about the pivot connection from an open state to a closed state. The first arm and second arm rotate at an angle relative to one another to allow loading of the expandable medical device into the first tapered channel or the second tapered channel and to allow positioning of the expandable medical device relative to a delivery device. When transitioning, the first tapered channel and the second tapered channel form a chamber that is configured to crimp the expandable medical device from the uncompressed state to the compressed state.
