  • Publication number: 20110066074
    Abstract: A biopsy needle comprises a first lumen open to a tissue penetrating distal tip of the needle for receiving a tissue sample therein and a second lumen in combination with a filter separating the first and second lumens from one another, the filter being configured to permit fluids to pass therethrough while preventing the sampled tissue from passing therethrough.

  • Publication number: 20110046512
    Abstract: A device for gathering tissue samples includes a needle defining a distal tissue penetrating tip. The needle includes an increased diameter proximal portion extending proximally from the distal tip. An outer diameter of the distal tip is smaller than an outer diameter of the proximal portion. The needle defines a lumen extending therethrough from a distal opening in the distal tip thereof to a proximal opening at a proximal end thereof. The lumen includes a distal portion having a first inner diameter and a proximal portion having a second diameter greater than the first diameter. The device also includes a stylet slidably received within the lumen.

  • Publication number: 20090177114
    Abstract: An echogenic needle aspiration device. In one embodiment, the device includes an echogenic needle, the needle including a tubular sidewall having a non-circular transverse cross-section over at least a portion of its length. The non-circular cross-sectional shape of the needle may be provided, for example, by radially spacing one or more straight, longitudinally-extending fins, ribs or other projections about the periphery of the needle and/or by providing the needle with a polygonal cross-sectional shape.

  • Publication number: 20080287740
    Abstract: Disclosed herein are various systems and methods for traversing an anatomic wall. A system can include a port that mates with an anatomic wall and provides a lumen for the passage of a guide tube of a transluminal device. The port can inhibit the passage of biological materials through the anatomic wall. Further described herein are methods for implanting the port and/or for inserting the transluminal device into a body cavity.
