Abstract: Example access devices, treatment devices, and kits useful in performing treatment under magnetic resonance imaging and related methods are described. An example access device includes an elongate tubular member formed of an MRI compatible material and moveable between a first, unexpanded configuration and a second, expanded configuration. The elongate tubular member has a central lengthwise axis, a proximal end, a distal end, an axial length, and a main body that defines a circumferential wall, a lumen, a proximal opening, a distal opening, and a main body opening. The main body opening is arranged in a spiral relative to the lengthwise axis and extends circumferentially along the circumferential wall. The main body opening extends along the entire axial length of the elongate tubular member from the proximal end to the distal end.

Abstract: Example tissue removal devices and kits useful in performing treatment under magnetic resonance imaging and related methods are described. An example tissue removal device includes an elongate member and a tubular member partially disposed over the elongate member. The elongate member has a lengthwise axis and a main body that defines a lumen, a proximal portion, a coil member, and a sharp edge. The coil member extends around a portion of the lengthwise axis in a first direction. The coil member extends from the away from the lengthwise axis and away from the proximal portion. The tubular member has a proximal end, a distal end, and a main body that defines a lumen and a slot. The slot extends from the distal end of the tubular member toward the proximal end of the tubular member. The slot is sized to receive a portion of the coil member.

Abstract: Example interventional medical devices useful in performing treatment under magnetic resonance imaging and related methods are described. A method of making a medical device useful in procedures performed under magnetic resonance imaging includes selecting a first material, selecting a second material that is different from the first material, incorporating the second material into a portion of the first material, and forming the first and second materials into a desired structure to form the interventional medical device. The second material can be melted and disposed in a void formed in the first material, and work hardened to increase magnetic susceptibility.

Abstract: An indwelling stent is provided. The stent includes a distal member that extends between a distal end portion and a proximal end portion and defines a lumen therethrough, and a proximal member that extends between a distal end portion and a proximal end portion and defines a lumen therethrough, wherein the distal member and the proximal member collectively define the stent, and wherein the distal and proximal members are discrete components and are telescopingly arranged with the distal end portion of the proximal member extending over an outer surface of the distal member.

Abstract: A catheter hub for use with a medical device and a catheter, the hub includes a hub body defining a fluid passageway in communication with a first aperture. Optionally, the hub body defines a second aperture that intersects the first aperture. The hub body attaches to the catheter wherein the fluid passageway and the catheter are aligned for fluid flow therethrough. The first aperture extends from and communicates with the fluid passageway to an exterior surface of the hub body and the first aperture configured to receive the medical device. The second aperture extends from and communicates with the first aperture and the exterior surface. A sealing element is sized for and positioned in either the first or the second apertures. The sealing element is configured to receive the medical device and seal both of the first and the second apertures.

Abstract: Example medical devices for performing treatment under magnetic resonance imaging and related methods are described. An example medical device includes a cannula and a plug. The cannula has a proximal end, a distal end, a first portion, a second portion, and a main body that defines a lumen and a passageway. The first portion extends from the distal end toward the proximal end. The second portion extends from the first portion toward the proximal end. The first portion is formed of first material. The second portion is formed of a second material that is different than the first material. The plug is disposed within the passageway and has a main body that defines a passageway in fluid communication with the lumen defined by the cannula. The plug is formed of a third material that is different than the second material.
