Exclusion device application instruments and related methods

An application instrument comprising:

• an end effector comprising
• a head configured to be disposed distally on a shaft operatively coupled to a user control,
• a first jaw mounted to the head and configured to releasably couple to a biased-closed exclusion device for an anatomical structure, and
• a second jaw mounted to the head and configured to releasably couple to the biased-closed exclusion device;
• wherein the first jaw is repositionable with respect to the head in a linear path using a linear track and a bearing follower;
• wherein the first jaw extends longitudinally in parallel to the second jaw;
• wherein the first jaw is repositionable with respect to the second jaw;
• and,
• wherein a cover is mounted to the head to contain the linear track and the bearing follower.

An application instrument comprising:

• an end effector comprising
• a head configured to be disposed distally on a shaft operatively coupled to a user control,
• a first jaw mounted to the head and configured to releasably couple to a biased-closed exclusion device for an anatomical structure, the first jaw extending from the head at a first angle that remains constant, and
• a second jaw mounted to the head and configured to releasably couple to the biased-closed exclusion device, the second jaw extending from the head at a second angle that remains constant;
• wherein at least one of the first jaw and the second jaw is movable relative to the head to reconfigure the exclusion device from a closed configuration to an open configuration, wherein the first angle is constant in the open configuration and the closed configuration, wherein the first jaw is repositionably mounted to the head, wherein the end effector further includes a cable operatively coupled to the first jaw and extending along the shaft and into engagement with a repositionable handle of the user control, and wherein the second angle is constant in the open configuration and the closed configuration.

An application instrument comprising:

• an end effector comprising
• 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 for an anatomical structure, 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,
• wherein the movable jaw is movable relative to the stationary jaw to reconfigure the exclusion device from a closed configuration to an open configuration,
• wherein the movable jaw is disposed on a traveler;
• wherein the traveler is movably disposed on the head;
• and
• wherein the end effector comprises at least one bearing operatively interposing the traveler and the head, and
• wherein the movable jaw is oriented generally parallel to the stationary jaw when the exclusion device is in the open configuration and the closed configuration.

An application instrument comprising:

• an end effector comprising
• a head configured to be disposed distally on a shaft operatively coupled to a user control,
• a first jaw mounted to the head and configured to releasably couple to a biased-closed exclusion device for an anatomical structure, and
• a second jaw mounted to the head and configured to releasably couple to the biased-closed exclusion device;
• wherein the first jaw is repositionable with respect to the head in a linear path using a linear track and a bearing follower;
• wherein the first jaw extends longitudinally in parallel to the second jaw;
• wherein the first jaw is repositionable with respect to the second jaw;
• and,
• wherein the first jaw is mounted to a traveler, the traveler including a post received by the bearing follower.
