Abstract: An embodiment of a medical device includes a proximal handle, a distal end effector, an elongate member connecting the end effector to the handle, and a sheath enclosing at least a portion of the elongate member. The handle may include a first mechanism coupled to one of the sheath and the elongate member to move the sheath relative to the elongate member, a second mechanism coupled to the elongate member to rotate the elongate member relative to the handle, and a locking mechanism coupled to the first mechanism to hold the first mechanism in a default position. Embodiments also include methods of positioning the medical device to perform a medical procedure.

Abstract: A medical retrieval device of an embodiment of the present disclosure includes a proximal handle, a sheath, and a retrieval assembly. The sheath extends from the handle and includes a lumen and a distal end opposite the handle. The retrieval assembly is moveable relative to the sheath to achieve a collapsed position of the retrieval assembly within the lumen and an expanded position of the retrieval assembly when extended outside the lumen. The retrieval assembly includes a plurality of legs. At least one of the legs includes a wire having an inner core at least partially surrounded by an outer layer.

Abstract: The invention relates to a suturing device used to place sutures inside the human body during various medical procedures. The suturing device includes an elongate body member, a needle deployment mechanism and a needle receiving portion. The elongate body member has a distal portion that defines an opening. The needle deployment mechanism is disposed at least partially within the elongate body member for moving a needle out of the opening at the distal portion of the elongate body member into a tissue; and the needle receiving portion is provided at the distal portion of the elongate body member to capture the needle. The needle receiving portion has a non-planar surface with walls that are non-parallel with respect to a longitudinal direction of the needle receiving portion such that the walls converge to form an aperture formed in the needle receiving portion to receive the needle.

Abstract: An ablation probe and method of manufacturing the ablation probe are provided. The probe comprises a probe shaft and a unibody electrode element. The unibody electrode element comprises a common electrode base located at the distal end of the shaft, and a plurality of electrode tines distally extending from the electrode base. The electrode element may be created by forming divisions (such as slits or slots) from a first end of an electrically conductive elongate member towards an opposing second end of the elongate member. Alternatively, the divisions can be formed from a first end of an electrically conductive sheet towards an opposing second end of the sheet, and then bent or rolled to form the elongate member. In either case, the common electrode base can either be separately mounted to a probe shaft, or the probe shaft can be formed from the elongate member, in which case, the electrode base will be integrated with the probe shaft as a unibody structure. The electrode tines can be optionally shaped, e.g., to proximally evert.
