Abstract: An example implantable microparticle for delivering therapeutic heat treatment comprises a generally spherical body. The body may be formed from a first material comprising a biodegradable material and a second material comprising a Curie temperature material. The biodegradable material may be a non-Curie temperature material or have a Curie temperature lower than a Curie temperature of the Curie temperature material. The first material and the second material are mixed to form a composite having a Curie temperature in the range of 35° C. and 100° C.

Abstract: An example medical device is disclosed. The medical device includes a catheter shaft including a distal end portion, wherein the distal end portion includes an ablation assembly. The ablation assembly includes an expandable frame including a base, an end region and a plurality of struts extending between the base and the end region, the struts defining a plurality of apertures along the frame. The ablation assembly also includes an electrical circuit coupled to an inner surface of the second end region of the frame, the electrical circuit including a plurality of ablation electrodes coupled thereto. Further, the expandable frame is designed to shift from a delivery configuration in which the ablation electrodes face inward from the inner surface of the expandable frame to an expanded configuration in which the ablation electrodes face away from the base of the expandable frame.

Abstract: A variable-length microwave ablation probe is provided. The probe is configured to have a range of resonant frequencies. The probe includes a microwave antenna, an outer conductor, and a cap. The probe further includes a radiation window that is at least partially transparent to microwave energy. The distal boundary of the outer conductor or the proximal boundary of the cap varies in distance from the probe distal end. The probe can have a choke length, an arm length, a radiating portion length, and a cap length. The lengths can each affect the resonant frequency of the antenna. Some examples provide a variable choke length, a variable arm length, a variable radiating portion length, and/or a variable cap length.

Abstract: An occlusive medical device system may include a microcatheter, an elongate shaft, an occlusive medical device, wherein a release wire is configured to releasably attach the medical device to the distal end of the shaft at a release mechanism, and an RF generator. In a first electrical state current is not flowing and in a second electrical state current is flowing to the medical device. The shaft is slidable between a first position wherein the medical device is disposed within the microcatheter, a second position wherein at least a portion of the medical device is disposed outside of the microcatheter and the release mechanism is disposed within the microcatheter, and a third position wherein the release mechanism is disposed outside of the microcatheter. The medical device system is configured to be in the second electrical state when the elongate shaft is in the second position.

Abstract: In some aspects, the present disclosure pertains to self-expanding emboli-capturing centering devices for centering a medical instrument in a conduit within a patient. The centering devices comprise (a) an elongate shaft, (b) a self-expanding centering member having an open distal end and an inner surface forming a central lumen with a flared distal portion, the centering member being configured such that a fluid flowing in a distal-to-proximal direction that is received by the open distal end flows proximally along the flared distal portion of the central lumen before exiting the central lumen through one or more openings in a proximal portion of the centering member, and (c) a filter material configured to filter the fluid received by the open distal end of the centering member. Other aspects of the present disclosure pertain to systems and methods employing such centering devices.
