  • Patent number: 10390848
    Abstract: A snare for snaring an article in a vessel of a vascular system or other body vessel. The snare includes a core cable having a proximal end portion and a distal end portion. The snare also includes first, second and third loops each having a proximal end portion and a distal end portion, and a mid-portion therebetween formed by spaced apart first and second sides connected together at the distal end portion of the loop. The mid-portions of each of the loops cross over mid portions of one of the other two loops, and the loops are only connected together at their proximal end portions, where they are gathered together and attached to the distal end portion of the core cable. The loops are movable between an open position and a closed position.

  • Patent number: 10076244
    Abstract: A physiological monitoring system includes a near-end portable monitoring module for generating first sensed data, capturing a user's first image, an image sensing module for synchronizing the first sensed data and the first image to form first combination data, and searching and connecting the corresponding near-end portable monitoring module to receive the first sensed data and display the near-end information display module corresponding to the screen of the first combination data, when the first sensed data includes a warning signal, the first combination data is transmitted and stored in the Internet by the second communication unit within a time period from a first time before the warning signal is issued to a second time for releasing the warning signal, and the first combination data within the time period from the first time to the second time is transmitted to the near-end information display module to display the first combination data.

  • Patent number: 6328701
    Abstract: The present invention includes a biopsy needle for use in a biopsy gun or as surgical instrument, capable of taking multiple samples, and a guiding needle holder for holding a biopsy needle. The biopsy needle includes an inner needle, also called a stylet, and an outer needle, also called a cannula, and a guiding needle holder. The stylet has a recess in the vicinity of its distal end which receives the tissue sample. The guiding needle holder includes an integrated spacer, and first and second connecting elements. The first connecting element holds the proximal end of the cannula and is displaceably attached along the length of the integrated spacer. The second connecting element holds the proximal end of the stylet and is fixedly attached to the distal end of the integrated spacer. The connecting elements each have an opening that facilitates insertion of the biopsy needle into a known biopsy gun in either the cocked or uncocked position.

  • Patent number: 6283925
    Abstract: A novel handle assembly has an opening that allows for the insertion of a needle set. The needle set is an integral unit and consists of an outer hollow cannula and an inner pointed tip stylet. The stylet and the cannula are capable of being urged forward separately into the biopsy area in a defined motion in relation to each other. The handle assembly includes a housing, and a slidable extension. In operation, the stylet and the cannula are inserted into the housing. The extension is moved rearward until the cannula is in a spring loaded position and a first locking member has engaged a second locking member. An adjustable wheel on the extension is turned to set the stylet to a predetermined distance for insertion into the biopsy area. The stylet and the cannula are inserted into a patient near the biopsy area. The stylet is then urged into the biopsy area to the predetermined depth.

  • Patent number: 5823970
    Abstract: A biopsy needle set 10 comprises an outer cannula 1 and an inner cannula 2. The outer cannula 1 includes an outer opening 14 and the inner cannula 2 includes an inner opening 12. The inner cannula 2 is rotatable relative to the outer cannula 1 such that the needle set 10 has an opened position wherein the inner opening 12 is located adjacent to the outer opening 14, and a closed position wherein the outer cannula 1 covers the inner opening 12. The needle set, in a closed position, can be inserted into a body in order to collect a tissue sample. Once properly inserted, the needle set can be moved to an opened position and then either selectively further inserted and closed to collect the tissue sample or closed to collect the tissue sample.

  • Patent number: 5752923
    Abstract: A biopsy instrument 40 includes a handle 1 and a disposable biopsy needle set or needle cartridge 20. The needle set includes a cannula 9 with a cannula hub 8 and a stylet 7 with a stylet hub 6. The needle set 20 is positionable within the handle 1 and actuatable thereby for purposes of taking a biopsy tissue sample. The needle set 20 and in particular the hubs 6, 8, in combination with the handle 1, perform the actuation sequence which allows the needle to be projected into the tissue to be biopsied and the cannula to be subsequently urged over the needle to collect the tissue.

  • Patent number: 5172702
    Abstract: Soft tissue biopsy apparatus (10) for obtaining a tissue specimen. An elongate housing (12) has an opening (20) at one end (14). A hollow cannula (26) is positioned within the housing, is reciprocally movable therewithin, and one end (28) of the needle extends through the opening for insertion into tissue (T) from which a specimen is to be taken. A needle (44) is positioned within the cannula, is reciprocally movable therewithin, and also has an end (46) extending through the opening for insertion into the tissue. This needle has a recess (50) adjacent its outer end in which a tissue specimen is captured. The needle is connected to a slide (68) by which the needle is moved independently of the cannula. A sleeve (110) installed over the housing is manually operable to move the slide to a selected and cocked position prior to insertion of the cannula/needle into the tissue. Movement of the slide moves the second needle from a first position to a second position while the cannula remains stationary.

  • Patent number: 5127916
    Abstract: A localization needle assembly includes an outer tubular cannula and a reinforced needle structure slidably mounted for movement within the outer cannula between extended and retracted portions, the needle structure includes a rearwardly extending retractable barb and a non-retractable barb which are contained within the outer cannula when the inner needle structure is extended while the surgeon locates a lesion. When the target area is reached, the inner needle structure is retracted, and the retractable barb is deployed through an opening in the sidewall of the outer cannula for anchoring the localization needle assembly in body tissue in the proximity of the lesion. When positioning is satisfied with precise targeting of the lesion, the outer cannula is removed, leaving both the fixed and retractable barbs in place with both barbs deployed and localizing the lesion to be removed for biopsy procedure.
