    摘要: 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.

    摘要: The invention is directed to devices and methods for separating and collecting a tissue specimen from a patient's target site. The device includes a probe member with a penetrating distal tip and a tissue receiving aperture, and a tissue cutting member which is rotatable disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture. The longitudinal edges of the aperture are preferably sharpened to engage the cutting edges of the tissue cutting member. Vacuum may be provided in the inner lumen of the cutting member to transport tissue therethrough. Rotation, rotational oscillation and/or longitudinal reciprocation of the tissue cutting member is effective to separate a tissue specimen from surrounding tissue. An accessing cannula having an tissue receiving aperture may be concentrically disposed within the probe member and about the tissue cutting member. The tissue cutting edge of the tissue cutting member preferably is longitudinally oriented and may have a cutting angle less than 90null with respect to the longitudinal axis of the tissue cutting member.

    摘要: In one form, the invention is directed to a method for forming a porous implant suitable for a cavity from which tissue has been removed, including mixing soluble alginate and a radiopaque imaging agent with water; incorporating a gas or a pore forming agent into the alginate-water mixture; transferring the alginate-water mixture with the gas or the pore forming agent into a mold to form the mixture into a solid body of desired shape; removing the water from the body; and converting at least part of the soluble alginate to a less soluble alginate. In another form, the invention includes forming a mixture by mixing about 0.5 percent to about 4 percent by weight chitosan into an acidified aqueous solution containing 1 percent to 25 percent by weight acetic acid, along with about 0.5 percent to about 5 percent by weight of a powdered radiopaque imaging agent.
