Abstract: A stent delivery system includes a core member and an expandable member coupled to the core member distal segment. A stent extends along the core member distal segment such that an inner surface of the stent is positioned over the expandable member. The stent has a primary heat-set configuration where the stent is radially expanded, and a secondary heat-set configuration where the stent is radially compressed. The expandable member is adapted to radially expand at least a portion of the stent from a radially compressed configuration toward a radially expanded configuration.

Abstract: Medical device loading apparatuses, systems, methods and kits are described. A loading apparatus comprises a main body having a passageway. The passageway has a first inner diameter, a second inner diameter, and a transition chamber. An expandable intraluminal medical device can be loaded into a delivery catheter using the loading apparatus by placing the device into the passageway and pushing the device along an axial path.

Abstract: A method for implanting a prosthesis centrally within a curved lumen includes loading a prosthesis into a delivery sheath, advancing the sheath in a patient towards the curved lumen to place at least the proximal end of the prosthesis within the curved lumen, and centering the proximal end of the prosthesis and/or the distal end of the sheath within the curved lumen. In a first advancing step, the outer catheter containing the inner sheath is advanced together towards the curved lumen to a location proximal of the curved lumen and, in a second advancing step, the inner sheath containing the prosthesis is advanced into the curved lumen to place at least the proximal end within the curved lumen while the outer catheter substantially remains at the location. After centering, the proximal end of the prosthesis is deployed centered within the curved lumen.

Abstract: A medical stent having a first end, a second end, and a central longitudinal axis extending from the first end to the second end, may include a plurality of first filaments each extending in a first helical path around the central longitudinal axis in a first direction and a plurality of second filaments each extending in a second helical path around the central longitudinal axis in a second direction. The plurality of first filaments may be interwoven with the plurality of second filaments. The first helical path of at least one of the plurality of first filaments may include a circumferential offset disposed between the first end and the second end.

Abstract: An expandable sheath is disclosed herein, which has a first polymeric layer and a braided layer positioned radially outward of the first polymeric layer. The braided layer includes a plurality of filaments braided together. The expandable sheaths further include a resilient elastic layer positioned radially outward of the braided layer. The elastic layer is configured to apply radial force to the braided layer and the first polymeric layer. The expandable sheath further includes a second polymeric layer positioned radially outward of the elastic layer and bonded to the first polymeric layer such that the braided layer and the elastic layer are encapsulated between the first and second polymeric layers. Methods of making and using the devices disclosed herein are also disclosed, as are crimping devices that may be used in methods of making the devices disclosed herein.

Abstract: Storage devices, loading devices, delivery systems, kits, and associated methods for implantable medical devices are described. An example embodiment of a storage device includes a storage member, a first cap, and a second cap. The storage member has a first end, a second end, and a main body that defines a first opening, a second opening, a passageway, a separating wall, and a plurality of holes. The passageway has a first portion and a second portion. The first portion extends from the first end of the storage member to the separating wall and the second portion extends from the second end of the storage member to the separating wall. Each hole of the plurality of holes extends through the separating wall and provides access between the first portion and the second portion. Each of the first and second caps is releasably attached to the storage member.

Abstract: An endoluminal device can comprise a flexible tubular wall and a frame member. The frame member can be comprised of a shape-memory material having sides with protrusions which are partially or substantially flattened when formed together with the flexible tubular wall to thereby create a bias in the side wall of the endoluminal device that resists deformation from a desired device profile during crush loading and is thereby resistant to invaginations when deployed.
