Abstract: Exclusion devices for anatomical structures, and related instruments and related methods, are disclosed. An exclusion device may include a first clamping portion, a second clamping portion opposing the first clamping portion, and/or a biocompatible fabric cover at least partially sheathing the first clamping portion and/or the second clamping portion. The cover may be generally tubular and/or may define a relaxed circumference when the first clamping portion and the second clamping portion are in a closed configuration. At least a portion of the cover may be configured to stretch to a stretched circumference of about 2× to about 3× the relaxed circumference when the first clamping portion and the second clamping portion are reconfigured from the closed configuration to an open configuration.

Abstract: The present disclosure pertains to cryogenic devices and related methods. A ferrule coupling according to at least some aspects of the present disclosure may include a male fitting including a bore; a female fitting including a bore, the female fitting sized to receive the male fitting; a conduit sized to fit within the bores of the male fitting and the female fitting, wherein a circumferential gap exists between an exterior of the conduit and an interior surface of the female fitting demarcating the bore; a first ferrule including dual conical surfaces and a cylindrical bore, the cylindrical bore sized to receive the conduit; a second ferrule including dual conical surfaces and a cylindrical bore, the cylindrical bore sized to receive the conduit; and/or a washer including dual conical surfaces and a cylindrical bore, the cylindrical bore sized to receive the conduit.
