摘要:
Biopsy devices (10, 10′) for acquiring tissue samples (59). In embodiments, exemplary biopsy devices include a cutter (127), a cannula (13) including a tissue-receiving cavity (42), a vacuum generating mechanism (17) and a tissue cutting mechanism (15). Vacuum generating mechanism draws tissue (47) into tissue-receiving cavity and tissue cutting mechanism cuts a tissue sample (59). Vacuum generating mechanism may provide positive air pressure for tissue sample ejection.
摘要:
A method of planning a procedure to deploy an interventional instrument comprises receiving a model of an anatomic structure. The anatomic structure includes a plurality of passageways. The method further includes identifying a target structure in the model and receiving information about an operational capability of the interventional instrument within the plurality of passageways. The method further comprises identifying a planned deployment location for positioning a distal tip of the interventional instrument to perform the procedure on the target structure based upon the operational capability of the interventional instrument.
摘要:
Systems and methods for non-serial, substantially simultaneous or simultaneous tissue sampling and placement of multiple markers/fiducials in a non-linear, distributed or three dimensional configuration. The systems and methods can be applicable to other forms and combinations of distributed/3 dimensional/spherical localization which may include a single procedure or combination of procedures that may include 3D biopsy, fiducial placement, brachytherapy seed placement, injection/infusion of bioactive materials (e.g., chemotherapy, small molecules, cellular materials, cells, caustic materials, proteolytics, embolic material, glue, etc.), thermally or electrically derived ablation.
摘要:
Ein erfindungsgemäßes endoskopisches Instrument (1, 40) umfasst ein langerstrecktes Schaftrohr (2), das ein axial durchgehendes im Wesentlichen zylindrisches Haupt-Lumen (3) zur Aufnahme eines Schafts (32, 46) einer Endoskopoptik (33, 43) aufweist, und ein Werkzeug, das an einem distalen Ende (4) des Schaftrohrs (2) angeordnet ist und das über ein langerstrecktes Übertragungselement von einem proximalen Ende (25) des Schaftrohrs (2) ansteuerbar ist, wobei das Schaftrohr (2) ein axial durchgehendes, in einer Querrichtung an das Haupt-Lumen (3) anschließendes Neben-Lumen (14) aufweist, das über einen verengten Übergangsbereich (15) mit dem Haupt-Lumen (3) verbunden ist und das das Übertragungselement aufnimmt. Die Erfindung betrifft auch ein endoskopisches Instrumentensystem.
摘要:
A microwave ablation system configured for use in luminal network, comprising: a microwave energy source (16); a tool (14) for treating tissue, the tool configured to receive microwave energy from the microwave energy source; an extended working channel (190) configured to provide passage for the tool; a locatable guide catheter (12) including a position sensor (96) positionable through the extended working channel and configured to navigate the extended working channel adjacent the target tissue (68) ; and at least one imaging modality for confirming placement of the tool within target tissue.
摘要:
The present invention relates to an ultrasound elastography system (10) for providing a shear wave elastography measurement result of an anatomical site (32), wherein the ultrasound signal and image processing assembly (16) is further configured to determine a location (94, 95, 96) of a shear wave elastography measurement result within the three-dimensional image (98) of the anatomical site (32) and to display the location (94, 95, 96) of a shear wave elastography measurement result to the user. Further, a corresponding method is provided.
摘要:
An endoscope treatment tool includes a sheath; a support part that is attached to a distal end portion of the sheath; a pair of forceps members that are arranged in front of the sheath and are supported so as to be relatively rotatable around a rotation shaft provided at the support part; a linear member that is inserted through the sheath so as to be capable of advancing into and retracting from the sheath, brings opposed surfaces, which are respectively provided closer to distal end sides of the pair of forceps members than the rotation shaft, closer to each other as the linear member is separated from the rotation shaft, and separates the pair of opposed surfaces from each other as the linear member approaches the rotation shaft; an elastic member that is supported by the linear member or the support part; and a locking portion that is provided on the linear member or the forceps members.
摘要:
An excisional device may comprise an introducer comprising a distal trough portion and a cutting assembly. The cutting assembly may comprise an axial band element configured to selectively bow out of and away from the distal trough portion and to retract into the distal trough portion and a helical cutting element wound around the axial band element. A rotating drum may be provided to cause die cutting assembly to selectively rotate, bow and retract according to a mechanically-driven first cutting profile that is defined by a shape of a channel formed in the drum. An optical guidance projector assembly may be coupled to the excisional device and may be configured to visually indicate when a distal portion of the excisional device is aligned with an imaging plane of an imaging probe and in a desired position.
