Medical devices and related methods

A medical device, comprising:

• an end effector comprising one or more arms, wherein each arm of the one or more arms comprises an extension surface and a retraction surface;
• an actuation portion comprising a prong;
• and
• a hub configured to receive the actuation portion and a proximal portion of each of the one or more arms, wherein the actuation portion is movable relative to the hub,
• wherein distal extension of the actuation portion is configured to cause the prong to contact the extension surface of one of the one or more arms to transition the one or more arms into an open configuration, and
• wherein proximal retraction of the actuation portion is configured to cause the prong to contact the retraction surface of one of the one or more arms to transition the one or more arms into a closed configuration.

A method of operating a medical device, comprising:

• delivering the medical device to a treatment site, wherein the medical device includes:
• an end effector comprising a first arm and a second arm, wherein each of the first arm and the second arm comprises an extension surface and a retraction surface;
• an actuation portion comprising a first prong and a second prong;
• and
• a hub configured to receive the actuation portion, the first arm, and the second arm, wherein the actuation portion is movable relative to the hub;
• transitioning the first arm and the second arm to an open configuration, wherein transitioning the first arm and the second arm to the open configuration includes distally extending the actuation portion, such that the first prong contacts the extension surface of the first arm and the second prong contacts the extension surface of the second arm;
• and
• transitioning the first arm and the second arm to a closed configuration, wherein transitioning the first arm and the second arm to the closed configuration includes proximally retracting the actuation portion, such that the first prong contacts the retraction surface of the first arm and the second prong contacts the retraction surface of the second arm.
