    摘要： An implant for insertion into a breast lumpectomy cavity to serve as a guide for orienting a radiation source relative to the breast lumpectomy cavity, includes a body formed of a bioabsorbable material comprised of chitosan having a porosity sufficient to ensure tissue in-growth before significant bio-absorption of the implant, the body having exterior margins. An interior orientation marker is spaced inwardly from the exterior margins of the body to facilitate relative orientation between the implant and the radiation source.

    摘要： The disclosure describes devices and methods for asymmetrical irradiation at a body cavity or site, such as after removal of tissue, e.g. biopsy or cancer. One device includes a lumen which is off-set or off-settable from a longitudinal axis to increase the intensity of radiation received from a radiation source by a first tissue portion surrounding the body cavity and to reduce or minimize radiation received by a second tissue portion (e.g. healthy tissue) surrounding the body cavity.

    摘要： The invention provides materials, devices and methods for marking biopsy sites for a limited time. The biopsy-marking materials are ultrasound-detectable bio-resorbable powders, with powder particles typically between about 20 microns and about 800 microns in maximum dimension, more preferably between about 300 microns and about 500 microns. The powders may be formed of polymeric materials containing cavities sized between about 10 microns and about 500 microns, and may also contain binding agents, anesthetic agents, hemostatic agents, and radiopaque markers. Devices for delivering the powders include tubes configured to contain the powders and to fit within a biopsy cannula, the powders being ejected by action of a syringe. Systems may include a tube containing powder, and a syringe containing sterile saline. The tube may be configured to fit within a biopsy cannula such as a Mammotome® or SenoCor 360™ cannula.

    摘要： A system for at least partially filling and marking a cavity at a site within a patient's body includes a marker delivery device having a chamber configured to contain a marking substance and having a mechanism configured to expel the marking substance. A quantity of the marking substance is contained within the chamber of the marker delivery device. The marking substance is configured to at least partially fill the cavity and form therein a porous bioabsorbable body. A delivery tube is coupled in fluid communication with the chamber of the marker delivery device. The delivery tube has a distal end with a discharge port through which the marking substance is expelled. A releasable remotely detectable distal tip is coupled to the distal end of the delivery tube and is configured to be released to remain within the porous bioabsorbable body within the cavity upon the formation thereof.

    摘要： A method for maintaining access to a biopsy site within a patient, includes forming a passageway from an opening in an exterior site on the patient to a desired location for a biopsy specimen within the patient; removing a tissue specimen from the desired location thereby leaving a biopsy cavity; providing a temporary catheter having an elongate shaft, a flexible proximal shaft section, and a distal shaft section having a cavity filling member thereon; inserting the cavity filling member on the distal shaft section into the biopsy cavity; inflating the cavity filling member after inserting the cavity filling member within the biopsy cavity, but before closing the opening, using the flexible proximal shaft section; placing the flexible proximal shaft section at an intracorporeal location; and closing the opening so as to seal the passageway.

    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.
