    摘要: A solution for forming a marker or filler mass for an intracorporeal site. The solution contains a polar, water soluble non-aqueous solvent such as dimethyl sulfoxide and a bioabsorbable, essentially water insoluble polymer such as polylactic acid, or copolymers of lactic acid and glycolic acid. The solution may be delivered to the biopsy site by a suitable syringe and delivery tube. The delivery tube is preferably provided with a releasable radiopaque element on the distal tip which can be released within the polymeric marker mass formed in the biopsy cavity.

    摘要: A device to access a desired tissue site within a patient's body and separate a tissue specimen from the tissue site. The device includes a probe member having a tissue penetrating distal tip having a plurality of concaved surfaces which form curved cutting edges at the intersection of adjacent concave surfaces. The probe member has an inner lumen which when subjected to a vacuum, secures tissue for the specimen to the surface of a distal tubular section of the probe which may be off-set from a central longitudinal axis. A circular tissue-cutting blade is configured to move longitudinally to sever a tissue specimen from tissue secured to the surface of the distal tubular section by the application of a vacuum to the inner lumen of the probe.

    摘要: The disclosure describes a device for asymmetrical irradiation of a body cavity or site, such as after removal of tissue, e.g. biopsy or lumpectomy. The device includes an elongated tubular shaft having an inner lumen and a tubular wall with a plurality of lumens extending within the wall which are configured for receiving a radiation source. The distal portion of the tubular shaft is cut into a plurality of longitudinally separated wall segments with a lumen extending within at least one of the wall segments. A support member is positioned within the separated wall segments to support and position the wall segments in a desired configuration for brachytherapy. An expandable member such as an inflatable balloon is mounted on the distal shaft portion about the separated wall segments wall which when inflated secures the distal shaft portion within a desired intracorporeal site for brachytherapy treatment.

    摘要: The invention is directed biopsy site markers and methods of marking a biopsy site, so that the location of the biopsy cavity is readily visible by conventional imaging methods, particularly by ultrasonic imaging. The biopsy site markers of the invention have high ultrasound reflectivity, presenting a substantial acoustic signature from a small marker, so as to avoid obscuring diagnostic tissue features in subsequent imaging studies, and can be readily distinguished from biological features. The several disclosed embodiments of the biopsy site marker of the invention have a high contrast of acoustic impedance as placed in a tissue site, so as to efficiently reflect and scatter ultrasonic energy, and preferably include gas-filled internal pores. The markers may have a non-uniform surface contour to enhance the acoustic signature. The markers have a characteristic form which is recognizably artificial during medical imaging. The biopsy site marker may be accurately fixed to the biopsy site so as to resist migration from the biopsy cavity when a placement instrument is withdrawn, and when the marked tissue is subsequently moved or manipulated.

    摘要: The invention is directed to a system and method for separating and collecting one or more tissue specimens from a target site within a patient and flushing the specimen to remove blood, debris and the like before the specimen is removed from the biopsy device. The flow of flushing fluid to the tissue collector is preferably controlled to coincide with delivery of one or more specimens to the collecting tray or basket of the device or after the receipt of the specimen within the tissue collector to ensure that the fluid is applied to a fresh specimen. The tissue tray or basket within the tissue collector has an open or foraminous portion to facilitate removal of fluid, such as the applied fluid and blood, and other debris from the tissue specimens on the tray. Vacuum is provided within the tissue collector, preferably under the tray to remove fluid and debris from the collector interior.

    摘要: A trocar assembly including a trocar and a trocar sheath and methods for accessing an intracorporeal site, e.g. biopsy or trocar site, using the trocar assembly. The trocar has a tissue penetrating distal tip, an elongated shaft and a proximal handle portion. The distal portion of the trocar sheath forms a releasable connection, such as a friction fit, with the shaft of the trocar and a slit that extends from the distal portion to the proximal end of the trocar sheath. The trocar assembly is advanced through the patient's tissue until the distal end of the trocar sheath is located at the desired site and then the trocar is removed. A treatment device such as a radiation balloon catheter is advanced through the interior of the sheath until the treatment component thereof is at the desired site.

    摘要: Devices and methods are disclosed for treatment to tissue surrounding a body cavity or other intracorporeal site, such as after removal of tissue, e.g. cancer. Such a device includes a treatment location on a distal portion of the device with one or more radiation shielding components that partially encircle a radiation source at the treatment location to control emitted radiation from the radiation source. The device minimizes radiation damage to healthy tissue surrounding the body cavity or other site while irradiating tissue not shielded by the radiation shielding components. A device embodying features of the invention can include a sealing member at a location on a shaft of the device proximal to a treatment location to seal the passageway leading to the body cavity.

    摘要: The invention is directed to devices and methods for accessing a desired target site within a patient's body and for separating and collecting a tissue specimen from the target site. The device includes a probe member or cannula with a penetrating distal tip, and a tissue cutting member which is disposed within the probe member to cut a tissue specimen from supporting tissue at the biopsy site. This probe is releasably secured to a housing to provide a plurality of discrete orientations of the probe about its longitudinal axis. Vacuum may be provided to the inner lumen of the cutting member to transport tissue through the inner lumen thereof. Rotation (and optionally longitudinal reciprocation) of the tissue cutter is effective to separate a tissue specimen from surrounding tissue at the target site. Vacuum or fluid pressure may be used to move the specimen cut from the target site proximally within the inner lumen defined at least in part by the culling member for collection.
