Abstract: Example medical systems useful in performing treatment under magnetic resonance imaging and related devices, kits, and methods are described. An example medical system includes a first medical device and a second medical device. The first medical device has a first passive marker. The first passive marker is formed of a first material that has a first magnetic susceptibility. The second medical device has a second passive marker. The second passive marker is formed of a second material that has a second magnetic susceptibility. The second passive marker creates an image artifact under MRI. The image artifact created by the second passive marker is altered under MRI when the first passive marker overlaps the second passive marker.

Abstract: Described are drainage catheter hub devices which seal the hub from leakage when connected to a catheter. The catheter hub includes a hub body having an aperture with a sealing element mounted therein and a fluid passageway that communicates with the aperture. The fluid passageway and sealing element are configured to receive a tension member. A lever arm attached to the hub body is operable to secure the position of the tension member in the sealing element in a locked position or allow movement of the tension member through the sealing element in an unlocked position. The lever arm is configured to engage and compress the sealing element to block fluid flow through the sealing element and the aperture when the lever arm is in any position. The hub body may include a centering tab to align the tension member along a longitudinal axis of the hub body.

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: The disclosure relates to medical devices and methods of assembling medical devices, such as MRI-compatible interventional wireguides. An example of a wireguide includes a series of individual segments, a plurality of connectors, and a plurality of spacers. Each segment in the series of individual segments has a first end and a second end. Each connector of the plurality of connectors joins adjacent segments in the series of individual segments to one another such that a first end of a first segment and a second end of a second segment in the series of individual segments are attached to a connector of the plurality of connectors. A spacer of the plurality of spacers is disposed between each pair of adjacent segments in the series of individual segments. Each of the segments in the series of individual segments is electrically insulated from an adjacent segment in the series of individual segments.

Abstract: The present embodiments provide a medical device for implantation in a patient comprising a stent and a valve. The stent comprises a proximal region comprising a cylindrical shape having a first outer diameter in an expanded state, and a distal region comprising a cylindrical shape having a second outer diameter in the expanded state. The second outer diameter is greater than the first outer diameter. A proximal region of the valve is at least partially positioned within the proximal region of the stent, and the distal region of the valve is at least partially positioned within one of tapered and distal regions of the stent. When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.

Abstract: Disclosed is a false lumen closure assembly for closing a false lumen in a body vessel including a compressed false lumen occluder, a carrier catheter and a retractable sheath. The compressed false lumen occluder includes a stent graft including at least one occlusive barrier across the stent graft to occlude blood flow through an interior of the stent graft. The carrier catheter carries the false lumen occluder and extends from a proximal end proximal of the false lumen occluder to a distal end distal of the false lumen occluder, and passes the false lumen occluder exteriorly of the stent graft. The compressed false lumen occluder and at least part of the carrier catheter are disposed in a lumen of the retractable sheath.
