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 for ablation of a target tissue is disclosed. The medical device includes a catheter assembly attached to a balloon for the ablation of the target tissue. The catheter assembly includes a proximal end and a distal end. The catheter assembly includes a plurality of individual shafts placed concentrically or adjacent to each other. Further, the plurality of individual shafts includes a respective lumen, wherein the lumens of the plurality of individual shafts can be configured to supply radio frequency (RF) energy to an RF transmitter placed inside the balloon and also to serve as the passageway for a fluid to travel within the balloon. The fluid flowing within the lumens of the catheter assembly can further help in expanding the balloon and transferring energy from the RF transmitter within the balloon to the ablation site via a plurality of windows attached.

Abstract: Systems and methods are provided for extracting a bodily fluid sample (e.g., an interstitial fluid sample) and monitoring an analyte therein. Certain of the systems include a a penetration member configured for penetrating and residing in a target site of a user's skin layer and, subsequently, extracting a fluid sample therefrom. The system also includes a pressure ring(s) adapted for applying pressure to the user's skin layer in the vicinity of the target site. The system is configured such that the pressure ring(s) is capable of applying pressure in an oscillating manner. Certain methods include penetrating the skin and applying pressure to the skin in an oscillating manner.
