    Abstract: In some aspects, the present disclosure provides a delivery device for delivering a detachable medical implant that comprises an elongated delivery member and a first engagement portion. The first engagement portion comprises a first proximal-facing surface, a first distal-facing surface, and a first lumen that is configured to accommodate an activation wire, wherein at least 50% of a surface area of the first proximal-facing surface is angled away from a proximal end of the first engagement portion. In other aspects, the present disclosure provides a medical delivery system comprising: such a delivery device; an implantable device comprising a medical device portion and a second engagement portion, the second engagement portion comprising a second lumen configured to accommodate an activation wire, a second proximal-facing surface and a second distal-facing surface; and an activation wire. Other aspects pertain to methods of medical device delivery using such a medical delivery system.

    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 microwave ablation probe including a probe body including a shielded portion and a radiation window that is at least partially transparent to microwave energy. The shielded portion includes a cannula, a coaxial cable within the probe body, and an antenna comprising a radiating portion for emission of microwave energy at a distal portion of the probe body, wherein the radiating portion is aligned with the radiation window. The probe body defines an irrigation path configured to carry cooling fluid to and from the distal portion of the probe body. At least one wall defining the irrigation path comprises a heat exchange surface having an average radius, wherein a surface area of the heat exchange surface is larger than a surface area of a smooth surface with a radius equal to the average radius.

    Abstract: Disclosed herein are devices, systems, and methods for monitoring a formation of an iceball at a cryoablation needle. An example method includes receiving an impedance from at least one electrode in an electrode arrangement that is disposed at a cryoablation needle distal portion. The electrode arrangement is configured to engage the iceball as the iceball is formed over the cryoablation needle distal portion so as to cause a change in the impedance. The example method includes determining one or more physical attributes of the iceball based on a rate of the change in the impedance.

    Abstract: The disclosure relates to systems and methods for irrigated bipolar radiofrequency ablation. The system includes an ablation probe that includes an elongate inner electrode assembly and an elongate outer electrode assembly. An irrigation path for irrigation fluid flow is defined between the outer surface of the inner electrode assembly and the outer surface of the outer electrode assembly. The irrigation path enables cooling fluid to be circulated within the probe body, cooling the outer electrode during ablation.
