A biopsy device includes a housing body, and a cannula assembly that has a first elongate cannula and a second elongate cannula coaxial with the first elongate cannula. The second elongate cannula has a lumen and a side wall having a vacuum side port in fluid communication with the lumen. A vacuum source is positioned in the housing body. The vacuum source has a chamber side wall having a chamber vacuum port. A seal is interposed in sealing engagement between the chamber vacuum port and the second elongate cannula. A trigger slide assembly is coupled to the housing body, and coupled to the cannula assembly, and is configured to move the second elongate cannula to align the vacuum side port of the second elongate cannula with the chamber vacuum port of the vacuum source to supply vacuum from the vacuum source to the lumen of the second elongate cannula.

This invention relates to electrosurgical systems for coagulation and ablation of tissue, including in relation to tissue biopsy.

An impact biopsy device is disclosed. The impact biopsy device may be configured to displace various cutting elements, such as an outer tubular member and cutting element and a cannula to sever a tissue sample from a patient. The impact biopsy device may comprise an actuation system configured to transfer displacement or force to the cutting elements by the impact of an element on another element.

A biopsy apparatus includes a piercing module having a probe drive slider coupled to a probe carrier body of a biopsy probe assembly, and has a primed position and a fired position. A nut housing has a home position and an extended position. A drive spindle is drivably coupled to a motor driveshaft, and is coupled to the nut housing. A firing spring is interposed between a motor housing and the probe drive slider. A release arm is pivotably coupled to a piercing module frame. When the probe drive slider is in the primed position and the release arm is in a latch position, the release arm is positioned to engage the probe drive slider to hold the probe drive slider in the primed position. A release slider releases the release arm from the latch position when the nut housing is moved from the home position to the extended position.

Provided are embodiments of systems, devices and methods to aid in or perform the capsulotomy procedure via access into an eye through a small incision. Embodiments of the present disclosure may employ the unique characteristics of shape-memory materials to enable device access into the eye through the requisite small incision size, and via simple mechanical means either to create a template for surgeons to follow in order to create an appropriately-sized capsulotomy, or to create such a capsulotomy via cutting, tearing, or abrading the lens capsule.

A biopsy device includes an elongated handle body having a proximal end portion and a distal end portion, a needle disposed within the handle body, first and second transducers, and a display. The needle is configured to move between a retracted position and a deployed position. The first and second ultrasound transducers are disposed within the distal end portion of the handle body. The first and second ultrasound transducers are angled relative to one another and define a space therebetween configured for passage of the needle.

A full core biopsy device includes a needle assembly having stylet, spoon, and at least one coring cannula. A window is located in at least one of the spoon and coring cannula. A excising finger is configured to prolapse through the window into a lumen of the inner spoon or cannula to sever a tissue sample upon translation or axial advancement of the excising finger.

Methods and systems are provided for reconstruction error assessment for an interventional tool utilized in an image guided interventional procedure. In one example, an error model based on a target lesion position within a tissue, one or more interventional tool parameters, and imaging system parameters may be utilized to estimate an expected reconstruction error for the interventional tool. In another example, when the interventional tool is within the tissue, the expected reconstruction error may be utilized along with observed tool shape and size to infer an actual tool position and shape within the tissue.

A breast biopsy lateral arm system includes a removable gun mount which attaches to a carriage that traverses along an X-axis defined by a lateral arm in order to position a biopsy needle relative to a patient. The carriage rides along the lateral arm on self-adjusting rollers which are loaded against the lateral arm by spring members. A cam-actuated carriage slide lock can be used to secure the carriage in a desired position relative to the lateral arm. A cam-actuated removable gun mount lock allows the gun mount to be quickly changed and offset orthogonally with respect to the X-axis. An X-axis stop can be used to establish a position to which the carriage can be returned with accuracy.

A biopsy device includes a disposable elongated probe component having a coaxial arrangement of an elongated tubular section and an elongated tissue cutting member, and having a coaxial arrangement of a first driven gear, a second driven gear, and a third driven gear. The first driven gear is configured to rotate the elongated tubular section. The second driven gear is configured to rotate to longitudinally move the elongated tissue cutting member. The third driven gear is configured to rotate or oscillate the elongated tissue cutting member. A driver component has a coaxial arrangement of a first drive gear, a second drive gear, and a third drive gear. The first drive gear is drivably engaged with the first driven gear. The second drive gear is drivably engaged with the second driven gear. The third drive gear is drivably engaged with the third driven gear.
