  • Patent number: 12201321
    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.

  • Publication number: 20220218881
    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.

  • Patent number: 10441256
    Abstract: Among other things, there are disclosed apparatuses and methods for medically sealing an opening in a vessel or wall. For example, in medical applications, a delivery tube is provided for insertion through a sheath into a vessel (e.g. a blood vessel). A dome-shaped seal fixed to a filament, an absorbent and/or compressible buffer, and a locking member are provided in the delivery tube. The delivery tube is configured so that it can be inserted into the vessel through a sheath. Tension is maintained on the filament to hold the seal against the tube or sheath. The sheath is pulled out, which pulls out the tube at the same time, leaving the seal over the opening in the vessel wall. The locking member compresses the buffer against the outside of the vessel and with the filament holds the seal in place against the inside of a vessel.
