A medical instrument for enhancing diagnosis and treatment comprising a handle, an ablation probe extending from the handle, a catheter extending from the handle. The catheter defines a lumen and the ablation probe is located within the lumen of the catheter. A port in fluid communication with the lumen of the catheter is configured for connection to a vacuum or fluid source, and application of a vacuum or an injection of fluid creates a consistent zone of permittivity around the ablation probe.

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 endoscope treatment instrument having a sheath, a rotation axis extending in a width direction orthogonal to a longitudinal direction of the sheath, a plate formed with a first opening through which the rotation axis passes and a second opening having a width different from the width of the first opening, a forceps piece rotatably supported about the first opening and the rotation axis passing through the second opening, and a wire connected to a proximal end portion of the plate.

A cannister system for containing a catheter, the cannister including a drive mechanism for driving the catheter from the cannister and into a luminal network of a patient, the cannister including an entrance point for insertion of a tool into the catheter.

A biopsy forceps device includes a tension member and an end effector including first and second jaws movable between an open configuration, in which the jaws are separated from one another to receive target tissue therebetween, and a closed configuration, in which cutting edges of the jaws are moved toward one another to cut a portion of the target tissue. The jaws define a tissue receiving space therebetween to house the cut tissue. The jaws are pivotable relative to one another, each of the jaws including a serrated cutting edge extending therealong, the end effector further including a tension member attachment including a proximal end coupled to the tension member. The attachment is movably coupled to the jaws so that distal movement of the attachment moves the jaws to the open configuration while proximal movement thereof moves the jaws to the closed configuration.

Certain aspects relate to systems and techniques for luminal network navigation. Some aspects relate to incorporating respiratory frequency and/or magnitude into a navigation system to implement patient safety measures. Some aspects relate to identifying, and compensating for, motion caused by patient respiration in order to provide a more accurate identification of the position of an instrument within a luminal network.
