Abstract: A medical device frame including an undulating frame element defining a series of peaks each defining a longitudinal splay angle, circumferential cant angle, or combinations thereof. In some examples, the series of peaks are non-overlapping when the frame is in an expanded configuration and overlap when the frame is in the collapsed configuration. The longitudinal splay angle and/or circumferential cant angle may remain relatively unchanged between the expanded and collapsed configurations (e.g., within about 15%).

Abstract: An implantable device delivery system is disclosed. The delivery system includes a constraining member situated between an interior layer and an exterior layer of a cover. The interior layer of the cover is disposed about an implantable medical device, and the exterior layer of the cover extends over a portion of the interior layer. The cover is generally tapered to minimize deployment forces. The constraining member is disposed about a portion of the interior layer and operates to constrain the implantable device to a delivery configuration. The cover and the constraining member are generally configured to be removed concurrently during deployment of the implantable device.

Abstract: Delivery systems (100) are described that include endoprostheses (102) configured to transition from compact, delivery configurations to enlarged, deployed configurations, delivery catheters including body (108) and tip (112) portions, the endoprostheses being received on body portions in the compact, delivery configuration, the tip portions including lips (114) configured to define pockets (114A) that releasably receive the endoprosthesis in the compact, delivery configuration, and constraints releasably maintaining the endoprostheses in the compact, delivery configuration. Additional and alternative delivery system features and associated methods are provided.

Abstract: An endoprosthesis having a length, a first end, a second end, and a longitudinal axis is disclosed herein, where the endoprosthesis is expandable from a compact, delivery configuration to an enlarged, deployed configuration. The endoprosthesis includes a plurality of rows of stent elements along the length of the endoprosthesis, where the plurality of rows include a first row and a second row located adjacent to the first row. The first row of stent elements has a first plurality of alternating apices, and the second row of stent elements has a second plurality of alternating apices. The first and second pluralities of alternating apices define a spaced apart, interlocking arrangement. The endoprosthesis also includes a discontinuous web of material comprising a plurality of web elements spaced from one another and interconnecting the first and second pluralities of alternating apices.

The apparatuses, systems, and methods may include at least one constraining fiber configured to form a warp knit surrounding a medical device with a first series of loops forming the warp knit with at least one of the first series of loops including a first portion forming a knot and a second portion arranged in addition to the knot.

Abstract: Various aspects of the present disclosure are directed apparatuses, systems and methods that include forming a constraining mechanism for an implantable medical device delivery. The apparatuses, systems and methods may include reducing a diameter of the implantable medical from a deployed diameter to a reduced diameter and interlocking one or more fibers along a length of the implantable medical device while the implantable medical device is in the reduced diameter to form the constraining mechanism.

Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include an implantable medical device and a constraining mechanism configured to constrain the implantable medical device to a delivery configuration. The constraining mechanism may include a single fiber arranged about the implantable medical device having a plurality of knots to maintain the constraining mechanism in constrained configuration with at least two of the plurality of knots being in contact in the constrained configuration.

In some examples, the series of peaks are non-overlapping when the frame is in an expanded configuration and overlap when the frame is in the collapsed configuration. The longitudinal splay angle and/0 or circumferential cant angle may remain relatively unchanged between the expanded and collapsed configurations (e.g., within about 15%).
