Exclusion devices for anatomical structures, and related instruments and related methods, are disclosed. An exclusion device for an anatomical structure may include a first beam, a second beam, and/or a first spring operatively coupled to the first beam and the second beam to exert a closing force on the first beam and the second beam. The first spring may be generally U-shaped and/or may include a first end portion and a second end portion generally opposite a connecting portion.

An automated heat shrink device, useful for forming a connection between two tubular sections having a polymeric outer surface jacket, for example, a connection between two sections of a district heating pipeline, and a method of use thereof. The device is configured such that it requires minimal clearance to either side of the pipeline when being used.

Exclusion devices for anatomical structures, and related instruments and related methods, are disclosed. An application instrument for an exclusion device may include an end effector including a head configured to be disposed distally on a shaft, a stationary jaw fixedly disposed on the head and configured to releasably couple to a first clamping portion of an exclusion device, the exclusion device being biased in a closing direction, and a movable jaw movably disposed on the head and configured to releasably couple to a second clamping portion of the exclusion device. The movable jaw may be movable relative to the stationary jaw to reconfigure the exclusion device from a closed configuration to an open configuration. The movable jaw may be oriented generally parallel to the stationary jaw when the exclusion device is in the open configuration and the closed configuration.

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.

Exclusion devices for anatomical structures, and related instruments and related methods, are disclosed. An exclusion device for an anatomical structure may include a first beam, a second beam, and/or at least one spring operatively coupled to the first beam and the second beam to exert a closing force on the first beam and the second beam and bias the first beam and the second beam in a closing direction. The spring may be operatively coupled to the first beam by a crimp connection.

An injection molding machine includes a safety door and a guide for slidably guiding the safety door in a direction of opening and closing a mold of the injection molding machine. The guide includes: a first guide part fixed to a machine base of the injection molding machine; a second guide part arranged on the safety door's closing direction side of the first guide part and configured to be removable from the machine base; and a coupling configured to connect the first guide part and the second guide part so that the second guide part can be moved onto the first guide part.

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.

Exclusion devices for anatomical structures, and related instruments and related methods, are disclosed. An exemplary method of making an exclusion device for an anatomical structure may comprise assembling a clamping portion of an exclusion device comprising a beam and a biocompatible fabric cover, and securing the cover on the beam by ultrasonic welding a first portion of the cover to a second portion of the cover.

An assembly is provided for induction welding. This assembly utilizes a heat shield (e.g., a mica heat shield) with a recess. An induction welding coil may be disposed within this heat shield recess during induction welding operations. The wall thickness of the heat shield within the recess may be reduced to enhance heat transfer to a workpiece during induction welding operations. The heat shield may be coated with a ceramic coating to enhance the heat shield's heat resistance and reduce heat shield flaking at the recess during induction welding operations.
