Medical devices, components, and methods for reusable devices or components

A medical device, comprising:

• a disposable portion, the disposable portion including a distal tip, the distal tip including a cavity at a proximal end of the distal tip,
• a handle, the handle comprising:
• a main body with a slot, the main body including a protrusion extending distally from a distal end of the main body, the cavity configured to receive and contain the protrusion of the distal tip when the disposable portion is in an engaged configuration with the main body,
• a moveable body,
• wherein movement of the moveable body is configured to control an end effector of the medical device.

A method of releasably engaging components of medical device, wherein the medical device includes a reusable portion including a handle with an actuator, wherein the actuator is a moveable body, wherein the medical device includes a disposable portion, the disposable portion including a wire and a crimp positioned at a proximal end of the wire, wherein the moveable body includes a release tab and a recess configured to receive the crimp, wherein a tab of the release tab is distal to the recess and blocks insertion of the crimp into the recess when the release tab is in an deactuated state, wherein in an actuated state the tab of the release tab no longer blocks insertion of the crimp into the recess, the method comprising:

• coupling the disposable portion to the reusable portion;
• inserting components of the disposable portion into a bodily lumen of a patient;
• treating a treatment site;
• removing components of the disposable portion from the bodily lumen of the patient;
• and
• uncoupling the disposable portion from the reusable portion.
