Introduced here is an ingestible device comprising a capsule, a camera, an antenna, and a propulsion component. The camera can capture images of various in vivo environments as the ingestible device traverses the gastrointestinal tract, and these images can be wirelessly transmitted to an electronic device located outside of the living body. The images may be transmitted to the electronic device for review by an operator responsible for controlling the ingestible device.

An elongated access device used in a medical system. The elongated access device slidably receives a medical tool and an ultrasound probe. The elongated access device includes a sheath and an intraluminal tip attached to the distal end of the sheath. The intraluminal tip includes ramp and nose donuts being spaced apart from one another and configured to be attached to one or more elongated sleeves. One or more orientation pins are engaged with the respective ramp and nose donuts and may be anchored within the sheath. The medical tool is engaged with a ramp formed in the ramp donut or a ramp received within the ramp donut. The ultrasound probe is configured to engage with the intraluminal tip so as to ensure that the medical tool directionality is oriented toward a target during a procedure.

A guided robotic system is disclosed. The guided robotic system includes a magnetic resonance imaging apparatus for real-time imaging of a subject, a computer system for analyzing images in real-time, and a robotic system for guiding a robotic arm based on real-time analysis of the images. A method of using a guided robotic system is also disclosed. The method includes acquiring live magnetic resonance images of a subject, analyzing the live magnetic resonance images to continuously identify a target portion of the subject, guiding a robotic arm towards an identified target portion of the subject based on the live magnetic resonance images, and performing a procedure at the target portion of the subject. The non-limiting procedures using the guided robotic system may include, for example, biopsy, stent insertion.

A system and method for supporting multi-probe guidance are disclosed. The system comprises: a medical guidance apparatus comprising: a rotatable portion which is rotatable around a first axis; an arc guide attached to or integrally formed with the rotatable portion, and a probe holder movably mounted on the arc guide. The probe holder is rotatable around a second axis perpendicular to the first axis by being translated along an arcuate path defined by the shape of the arc guide. In one embodiment, the probe holder includes a plurality of probe channels to guide a corresponding plurality of probes parallel to each other towards a subject. In other embodiment, the probe holder includes a single probe channel which is offset from a center point of the guidance apparatus by a fixed distance such that each probe can be inserted sequentially through a different insertion point without colliding at the center point.

A magnetic robot is provided. The magnetic robot comprises: a moving part which could be moved by means of a control of an external magnetic field; and an inspection part which is coupled to a frontal end of the moving part, wherein the inspection part comprises: a body provided with a tissue sampling needle at the frontal end thereof; a cover for covering the body; and a cover-moving part for moving the cover between a first position and a second position, wherein in the case where the cover is positioned in the first position, the tissue sampling needle is housed within the cover, and in the case where the cover is positioned in the second position, the tissue sampling needle is exposed to the outside of the cover.

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.

A biopsy needle comprises a first lumen open to a tissue penetrating distal tip of the needle for receiving a tissue sample therein and a second lumen in combination with a filter separating the first and second lumens from one another, the filter being configured to permit fluids to pass therethrough while preventing the sampled tissue from passing therethrough.

Methods and systems are provided for molecular breast imaging. In one embodiment, a method for nuclear medicine imaging comprises: during an acquisition of emission data from an anatomy of interest, calculating an average counts per pixel in non-target tissue; and responsive to the average counts per pixel reaching a threshold, automatically stopping the acquisition. In this way, an amount of time spent by a patient undergoing an MBI procedure is optimized for the patient.

Certain aspects relate to biopsy apparatuses, systems and techniques for biopsy using a biopsy pattern. Some aspects relate to moving a distal portion of a medical instrument to one or more sample locations of the biopsy pattern and guiding the instrument to obtain tissue samples from the sample locations within the biopsy pattern. Some aspects relate to obtaining the biopsy pattern and adjusting the sample locations within the biopsy pattern based on various factors such as anatomical features.

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.
