摘要:
A biopsy marking apparatus (10) for placing a radiopaque marker at the location of a percutaneous biopsy. The biopsy marking apparatus comprises an introducer (12) in combination with a radiopaque marker. The introducer (12) ejects the radiopaque marker at the location of the biopsy. The introducer (12) is configured to completely eject the radiopaque marker and prevent if from being subsequently drawn into the introducer (12) as the introducer is removed from the biopsied tissue mass. The radiopaque marker has enhanced radiopaque characteristics and enhanced non-migration characteristics.

A device for inserting securing anchors into human or animal tissue, in particular for securing plastic meshes, comprises an actuation part (10) that can be pushed forwards and returned for an insertion procedure, a needle (13) that is pushed forwards and drawn back by the actuation part (10), several securing anchors arranged on the needle (13) passing through their channels (8), a press-in part (16) which is pushed forwards as the actuation part (10) is advanced and with which the securing anchor (3) arranged at the very front, relative to the direction of advance, and located in a standby position in the area of the needle tip, is pressed into the tissue, and a reloading mechanism with which the securing anchor (3) located behind the securing anchor to be pressed into the tissue is displaced in the direction of the needle tip during the insertion procedure. The press-in part (16) comprises a portion (17) which, when the device is filled completely with securing anchors (3), extends over several of the securing anchors (3) in the direction to the front end of the needle (13) and has, at its front end, engagement elements (18) for engaging on the rear face of at least one protruding part (5) of a securing anchor (3). During the resetting of the actuation part (10), the engagement elements (18) of the press-in part (16) can be carried over or around at least one protruding part (5) of the next behind securing anchor (3) and can be brought to rest on the rear face of at least one protruding part (5) of this next behind securing anchor (3).
摘要:
A marking device (10) according to one embodiment of the invention comprises a handle (14), a cannula (16) having a cannula distal end (180) and slidably mounted to the handle (14), and a stylet having a stylet distal end and slidably mounted to the handle (14) in the cannula (16). The stylet distal end is spaced proximally of the cannula distal end (180) to form a marker recess that receives an imaging marker. The marking device (10) further comprises an actuator (20) operably coupled to the cannula (16) to effect retraction of the cannula (16) into the handle (14) following implantation of the imaging marker. The imaging marker can be implanted by advancing the stylet relative to the cannula (16) to eject the imaging marker from the marker recess, or the cannula (16) can be retracted relative to the stylet to expose the imaging marker.
摘要:
The invention provides a device for percutaneously implanting an imaging marker for identifying a location within a tissue mass. The subcutaneous imaging marker comprises at least a first element and a second element, each of which have a primary imaging mode. The primary imaging mode of the first element is different from that of the second element.
