A method for displaying guidance information using a graphical user interface during an medical procedure comprises displaying, in a first mode of the graphical user interface, first image data from a perspective corresponding to a distal end of an elongate device. The first image data includes a virtual roadmap. The method also comprises transitioning from the first mode of the graphical user interface to a second mode of the graphical user interface. The transition is based on an occurrence of a triggering condition. The method also comprises displaying, in the second mode of the graphical user interface, second image data from a perspective corresponding to the distal end of the elongate device. The second image data includes a target indicator corresponding to a target location and an alignment indicator corresponding to an expected location of the medical procedure at the target location.

An airbag tube apparatus has a hollow tube with a closed end and an open end. A side hole is disposed near the closed end; when matter leaves the airbag tube apparatus, it enters the hollow tube from the side hole and flows out of the open end. A balloon is attached to the hollow tube, and connected to a vent. The balloon in a large volume can flexibly fix animal tissue. A vent is connected to the balloon, a valve, and a pneumatic module to form an air inflator to inflate, hold and deflate the balloon. The valve opens and closes the liquid flow in the vent, and is controlled by a circuit module; the pneumatic module, providing inflating function, is controlled by the circuit module; the circuit module, has a microprocessor unit, a memory unit and an input-and-output unit.

An imaging catheter includes a shaft extending along a longitudinal axis between a proximal end and a distal end, a plug at the proximal end, and an imaging sensor at the distal end. The plug includes electrical terminals oriented perpendicular to the longitudinal axis. The imaging sensor includes an infrared transmitter and an infrared receiver.

A light-intensity-based forced sensor comprises a Sarrus linkage, a biasing mechanism, a light emitter, and a light detector includes a first plate, a second plate, and at least one collapsible linkage pivotably coupled to both the first and the second plates. The biasing mechanism biases the collapsible linkage toward an extended configuration. The light emitter is coupled with and displaceable with the first plate; and the light detector is coupled with and displaceable with the second plate and configured to receive light emitted from the light emitter and generate an electrical signal in response to light received from the light emitter, wherein the generated electrical signal provides an indication of the distance between the first plate and the second plate. The sensor can be distally mounted on, e.g., an endoscope to provide haptic feedback at the distal end of the endoscope.

An interventional medical device includes an insertion tube extending between a proximal end and a distal end. The distal end configured to be inserted into internal tissues of a patient during a medical procedure. The insertion tube has an internal channel. The interventional medical device includes a tool received in the internal channel of the insertion tube. The tool has a tool body and a needle at an end of the tool body forms a tip of the tool. The tool body forms a tool channel. The interventional medical device includes a pressure sensor module received in the tool channel. The pressure sensor module includes a pressure sensor and a carrier holding the pressure sensor. The carrier is coupled to the tool body to position the pressure sensor in the tool channel proximate to the tip of the tool for measuring pressure of fluid of the internal tissues of the patient.

A system for assisting endoscope tracking used to track a travel path of an endoscope probe within an organ includes three position sensors and three distance sensors which are surrounding an endoscope probe, and a computing device. The said three position sensors respectively sense a first coordinate, a second coordinate and a third coordinate relative to a navigation origin. The said three distance sensors respectively sense a first distance, a second distance and a third distance apart from an inner wall of the organ. The computing device obtains a position coordinate of the endoscope probe relative to the navigation origin according to the first coordinate, the second coordinate and the third coordinate. The computing device further determines whether to send a warning message according to the first distance, the second distance and the third distance.

Disclosed is an endoscope for measuring intra-organ pressure (e.g., intragastric pressure), and more particularly an endoscope for measuring intra-organ pressure (e.g., intragastric pressure) and visualizing the response of an adjacent sphincter (e.g., lower esophageal sphincter) to changes in the intra-organ pressure.

An endoscope is provided and includes a flexible insertion tube; a distal end assembly provided at an end of the insertion tube; and a cooling medium tube provided in the inside of the insertion tube, and connected to the distal end assembly. A cooling medium for cooling the distal end assembly is introduced through one of the insertion tube and the cooling medium tube, and discharged through the other of the insertion tube and the cooling medium tube. Since the endoscope is configured such that the cooling medium directly contacts with a heating element or a conductor through which the heat of the heating element is conducted, the cooling effect of the front end portion of the endoscope is improved.

A system and method is configured for use with an endoscope, a biopsy needle, and a data acquisition system. The system includes a sensor tip and a pressure sensor coupled to the sensor tip and having at least one piezo-resistor component with an internal-facing side and an external-facing side, and an opening adjacent to the at least one piezo-resistor component to allow fluid access to the internal-facing side and the external-facing side. The system also includes a tubing member with a distal end and a proximal end, the sensor tip coupled to the distal end, the sensor tip and the tubing member configured to be routed through the biopsy needle and connection elements coupled to the proximal end of the tubing member, the connection elements configured to mount the tubing member relative to the biopsy needle and to couple the pressure sensor to the data acquisition system.

Systems and methods are provided for inserting an endoscope through an anatomical cavity to a target site. A speaker is positioned externally proximate to a patient and the endoscope is inserted into the anatomical cavity. A signal is received from at least one sensor positioned near the distal end of the endoscope. The signal is indicative of vibrations induced in internal cavity tissue by the externally positioned speaker. A first anatomical structure in contact with the distal end of the endoscope is identified based on the signal indicative of vibrations induced in the internal cavity tissue by the externally positioned speaker. As the distal end of the endoscope moves from the first anatomical structure into contact with other anatomical structures along a path to the target site, the received signal indicative of induced vibrations changes correspondingly and is used to guide the endoscope to the target site.
