  • Patent number: 9801688
    Abstract: An intracorporeal marker delivery system includes a delivery device including a delivery cannula and a plunger. The delivery cannula has an inner lumen, a distal tip, and a discharge opening in communication with the inner lumen. A radiographically detectable marker having a fibrous-body and a radiographically detectable marker element coupled to the fibrous body is disposed within and pushable by the plunger through the inner lumen of the delivery cannula. An MRI detectable distal tip plug is disposed at least in part within a distal portion of the inner lumen distal to the radiographically detectable marker, and configured to partially occlude the discharge opening in the delivery cannula. An ultrasound detectable short term marker is interposed between the radiographically detectable marker and the MRI detectable distal tip plug in the inner lumen of the delivery cannula.

  • Patent number: 9375204
    Abstract: A structurally integrated biopsy system includes a movable base having wheels to facilitate movement of the structurally integrated biopsy system. On the movable based there is mounted a tissue removal system, an ultrasound imaging system, and a controller. The tissue removal system includes a probe connector configured to connect to a tissue removal probe. The ultrasound imaging system is configured to generate an ultrasound image of a body region of a patient, and has an image display system having an image display screen to display ultrasound images taken by the ultrasound imaging system. The controller is configured to be in communication with each of the tissue removal system and the ultrasound imaging system to both provide control information for the ultrasound imaging system and provide control information for the tissue removal system in the structurally integrated biopsy system.

  • Patent number: 8880154
    Abstract: An intracorporeal marker includes a fibrous unitary marker body having bioabsorbable fibers compressed into a compressed configuration, and bound in the compressed configuration by a polymer binding agent. The intracorporeal marker may be incorporated into an intracorporeal marker delivery device having a delivery cannula which has a distal tip, an inner lumen and a discharge opening in communication with the inner lumen. The compression and binding occur prior to insertion of the fibrous unitary marker body into the inner lumen of the delivery cannula. The fibrous unitary marker body is slidably disposed within and pushable through the inner lumen of the elongated delivery cannula proximal to the discharge opening.

  • Patent number: 8622907
    Abstract: A biopsy system is disclosed that has a tissue removal system, an imaging system, an image display system and a common input console for these systems. The tissue removal system can have a mechanical tissue cutting blade or an electrosurgical cutting element and the tissue removal system is capable of handling both tissue cutting configurations. The imaging system is preferably an ultrasound imaging system and the image display system has a video screen for displaying diagnostic ultrasound images from an ultrasound probe. The common input console preferably has a touch screen display and a keyboard to facilitate operation of the tissue removal system, the ultrasound imaging system and the image display system from the same console.

  • Patent number: 7983734
    Abstract: The invention is directed to an intracorporeal marker, a delivery device and assembly for such marker and the method of delivering one or more of the markers to an intracorporeal location within a patient. The marker is a body formed at least in part of a bioabsorbable fibrous material such as a fibrous mat or fabric. The delivery devices preferably also include one or more bioabsorbable short term markers which are configured to expand within the body cavity due to contacting a body fluid. The fibrous marker has a radiographically detectable member which preferably hold a portion of the fibrous body in a compressed condition. Preferably, the fibrous marker has a fibrous felt core formed of bioabsorbable material with a fabric jacket formed of bioabsorbable material. Therapeutic, diagnostic and binding agents may be incorporated into the fibrous body of the marker.
