A medical device system includes a tubular medical device and a diameter reducing arrangement. The tubular medical device comprises a tubular graft body having a proximal end and a distal end. The diameter reducing arrangement is configured for constricting the medical device, and includes a strand section having first and second ends and being immovably secured to the medical device at the first end and at the second end. The second end is a first circumferential distance from the first end by way of a path along the strand section In a constricted configuration of the medical device a first portion of the strand section extends back on itself to form a first double-stranded tail leading to a first loop, the first tail extending circumferentially against the graft body, constricting the medical device by the strand section restricting the first circumferential distance between the first and second ends of the strand section.

A loading dilator may include a first portion and a second portion. The first portion may include a first proximal end, a first distal end, and a first outer surface extending between the first proximal end and the first distal end. The second portion may include a second proximal end, a second distal end, and a second outer surface extending between the second proximal end and the second distal end. The first outer surface may include a plurality of slits extending along at least a portion of the length of the first portion. The plurality of slits may be spaced apart circumferentially around a longitudinal axis of the first portion. The length of the second portion may be smaller than the length of the first portion.

The disclosure relates to methods of imaging a portion of a body vessel using magnetic resonance imaging (MRI), methods of performing interventional medical treatment under MRI, interventional medical devices, such as wire guides, useful in performing treatment under MRI, and methods of making interventional medical devices. A method of imaging a portion of a body vessel of a patient using MRI includes advancing through a body vessel an end of a wire guide comprising a continuous metal core member and a continuous jacket disposed over the entire core member through a body vessel and scanning the portion of the patient that is positioned within an MRI scanner and that includes a portion of the body vessel within which the end of the wire guide is disposed. A secondary medical device, such as a catheter, can be disposed over the wire guide and manipulated in the method.

Disclosed herein is a medical device including a camera including a movable member including an outer surface with a longitudinally-extending cross-sectional geometry configured to complement a longitudinally-extending cross-sectional geometry of a surface of a lumen in an elongate tube housing the movable member so as to prevent rotation of the movable member relative to the elongate tube. The device allows the operator to maintain visual orientation as the movable member is translated proximally and distally relative to the elongate tube.

A system for electrically and mechanically connecting an electrical cord and a medical device includes: a cord-side connector including a cord connecting surface, a cord-side conductive portion, and at least one protrusion extending from an intermediate surface; and a device-side connector including a device connecting surface, a device-side conductive portion, and a recess configured to slidably receive the cord-side connector in a sliding direction, the recess including at least one slot configured to slidably receive the at least one protrusion to guide the cord-side connector in the recess in the sliding direction, where the at least one protrusion and slot are configured to form a mechanical connection through an interference fit upon slidable receipt of the at least one protrusion into the at least one slot, and the cord-side conductive portion and the device-side conductive portion are configured to contact each other upon formation of the interference fit.

A stent comprises a framework that includes a sequence of cells that each occupy a discrete segment of the stent length, and each of the cells includes a plurality of struts with ends connected at respective vertices. An adjacent pair of the cells are attached to one another by a plurality of T-bars that each include a column defining a long axis that extends parallel to the stent axis, and a top bar attached to one end of the column. An opposite end of the column is attached to a first cell, and the top bar is attached at opposite ends to a second cell of the adjacent pair of cells. The column has a minimum width perpendicular to the long axis that is wider than a maximum width of each of the struts, and the column defines at least one slot. The top bar includes a curved edge on an opposite side from the column, and the curved edge straddles the long axis.

Disclosed is a stent graft, including a graft body, a sealing stent at the proximal end of the graft body and completely overlapped by the graft body, and a diameter reducing loop arrangement. The sealing stent includes proximal apices at a proximal end thereof and distal apices at a distal end thereof. The diameter reducing loop arrangement includes a loop element. The loop element includes a first end, a second end, and a strand section from the first end to the second end. The first end is attached to the distal end of the sealing stent. The loop element is configured to pass circumferentially around the distal end of the sealing stent and have a release wire pass through a loop at the second end. The diameter reducing loop arrangement is configured to constrict the distal apices of the sealing stent and cause the sealing stent to adopt a substantially conical or frustoconical shape.

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.

A control assembly for a steerable medical device shaft, the control assembly may include a steerable-shaft handle; and an elongate docking translating base, including a first-end opening dimensioned to receive and operably engage a portion of a separate medical device handle and a second-end ball. The steerable-shaft handle surrounds a longitudinal passage extending distally from a first-end terminus that includes a socket dimensioned to engagingly receive the second-end ball. The longitudinal passage includes a path in mechanical communication with the first-end opening of the base. The base includes at least two steering wires that extend through the steerable-shaft handle in mechanical communication with a steerable length of a shaft length disposed distal of the steerable-shaft handle.

An endoscopic device is provided. The endoscopic device may comprise a distal end and a proximal end. The proximal end may be opposite the distal end. The endoscopic device may further comprise a handle at the proximal end and a tube extending from the handle towards the distal end of the endoscopic device. The endoscopic device may further comprise an accessory channel. The accessory channel may extend through the tube. The endoscopic device may further comprise a slide, the accessory channel extending through the slide, and a curved track disposed adjacent to the proximal end of the endoscopic device. The slide is movable within the curved track to cause movement of the accessory channel within the tube.
