Medical system using optical shape sensing fiber for triggering an event

A method for triggering an event in a medical system using an interventional elongated medical device having an optical fiber configured for optical shape sensing of the medical device;

• the method comprising:
• detecting a confined manipulation section of the medical device, the confined manipulation section being a length of the medical device configured to be gripped by a user for maneuvering the medical device inside a body and for applying a user manipulation to the confined manipulation section, the user manipulation comprising at least one of a pinch into an outer wall of the medical device or a deformation of the confined manipulation section into a predefined shape, while the user grips the confined manipulation section;
• analyzing the user manipulation applied to the confined manipulation section based on optical shape sensing of the medical device in the confined manipulation section;
• and
• triggering the event in response to identifying the user manipulation in the confined manipulation section as being associated with the event to be triggered, the event to be performed at a distal portion of the medical device.

A non-transitory computer readable medium comprising computer program instructions that, when executed by a computer, cause the computer to:

• detect a confined manipulation section of medical device, the confined manipulation section being a length of the medical device configured to be gripped by a user for maneuvering the medical device inside a body and for applying a user manipulation to the confined manipulation section, wherein the user manipulation comprises at least one of a pinch into an outer wall of the medical device or a deformation of the confined manipulation section into a predefined shape, while the user grips the confined manipulation section;
• analyze the user manipulation applied to the confined manipulation section based on optical shape sensing of the medical device in the confined manipulation section;
• and
• trigger an event in response to identifying the user manipulation in the confined manipulation section as being associated with the event to be triggered, wherein the event is to be performed at a distal portion of the medical device.
