    摘要： A method for forming a porous implant suitable for a cavity from which tissue has been removed includes incorporating a gas or a pore forming agent into an alginate solution; transferring the alginate solution with the gas or the pore forming agent into a solidified body mold having a desired shape with an outer surface; removing the water from the solidified body; and subjecting the solidified body to a conversion solution to convert the outer surface to a less soluble alginate creating a composition comprising the outer surface having less soluble alginate and a core having more soluble alginate.

    摘要： A system for controlling an electrosurgical electrode of a medical device includes a hand-held electrosurgical electrode having cutting probe. A return electrode is positioned remote from the electrosurgical electrode. An RF generator is coupled to the electrosurgical electrode and to the return electrode, and includes an RF amplifier. The RF generator generates an RF signal at a first RF power level for tissue cutting and generates the RF signal at a second RF power level greater than the first RF power level to initiate tissue cutting. A sensor monitors an electrical characteristic associated with the electrosurgical electrode. A controller coupled to the RF amplifier maintains a desired RF power output and a desired RF duty cycle at the first RF power level by adjusting a DC input voltage applied to an output stage of the RF amplifier based on the monitored electrical characteristic associated with the electrosurgical electrode.

    摘要： A tissue cutting member includes a distal tubular portion having a side wall defining a lumen, a longitudinal axis, and a flared distal section. The flared distal section has an inclined distal tip and an outwardly flared distal tubular portion that defines an inner tissue receiving aperture. The inclined distal tip has a beveled front face with a leading tissue cutting edge and a trailing cutting edge. A single longitudinally oriented opening is in the side wall in the flared distal section which radially opens to the lumen. The longitudinally oriented opening has an open distal end and is configured to extend from a closed proximal end to the open distal end. The closed proximal end has a relief opening with a transverse dimension larger than a transverse dimension of the longitudinally oriented opening adjacent the relief opening. The longitudinally oriented opening diverges to intersect the trailing cutting edge.

    摘要： A method for marking a surgically formed cavity in a patient includes providing an implant comprising a matrix material and a marking material, the matrix material configured to be elastically compressible; modifying the shape and size of the implant to fit the shape and size of the surgically formed cavity in the patient, the implant being configured to fill the surgically formed cavity and support tissue surrounding the surgically formed cavity and to allow in-growth of fibrous tissue into and replace at least a portion of the matrix material; and inserting the implant into the surgically formed cavity.

    摘要： A method for collecting a tissue specimen from a target site within a patient includes rotating an elongated tubular section about a longitudinal axis to provide a desired aperture orientation of a tissue receiving aperture; applying a vacuum within the elongated tubular section to draw tissue at the tissue site through the tissue receiving aperture of the elongated tubular section into the interior thereof; advancing an elongated tissue cutting member longitudinally within the elongated tubular section to cut a tissue specimen from the tissue extending into the elongated tubular section; and applying a vacuum to the proximal end of the elongated tissue cutting member for transporting a cut tissue specimen through the inner lumen of the elongated tissue cutting member to discharge the cut tissue specimen directly from the proximal end of the elongated tissue cutting member into a tissue collection device.
