    Abstract: A medical device system may include an elongate shaft having a lumen extending from a proximal end to a distal end, a proximal release wire, and a distal release wire. The proximal release wire may extend distally from a proximal end configured to remain outside the body to a distal end and may be slidably disposed within the lumen of the elongate shaft. The proximal release wire may include a distal stopper coupled to the distal end thereof. The distal release wire may extend distally from a proximal end to a distal end and may be slidably disposed within the lumen of the elongate shaft. The proximal end of the distal release wire may be slidably coupled to the distal end of the proximal release wire. The distal release wire may be configured to releasably attach a medical device to the distal end of the elongate shaft.

    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: The present invention provides systems and methods for accurately delivering embolic coils within a body lumen of a patient, as well as recapturing deployed embolic coils for removal or repositioning. In various embodiments, an embolic coil delivery system may include an elongate sheath with a lumen extending therethrough. An elongate shaft may be slidably disposed within the sheath. The shaft may comprise a split-distal end that defines an aperture. The split-distal end may be moveable between a contracted configuration and an expanded configuration. An embolic coil may include a proximal ball-tip that may be reversibly disposed within the aperture of the split-distal end.
