    摘要: The invention is directed to an electrosurgical device having a shapeable elongate cutting electrode having a free distal end with an exposed length of at least 0.5 inch and secured by its proximal end to the distal end of a handle. The electrosurgical device is designed for use with a high frequency electrosurgical generator which has an output at a frequency of between about 1 MHz and about 10 MHz, preferably about 3 to about 8 MHz. Preferably, the output has an essentially sinusoidal waveform with little harmonic distortion. The methods provide for the enhanced cutting of a variety of tissue including muscular, connective, glandular and fatty tissue. The device is particularly suitable in performing a breast biopsy.

    摘要: The invention provides marker delivery devices, assemblies, and methods. Assemblies embodying features of the invention include marker delivery devices having a delivery tube with an orifice, markers, and a plug releasably disposed in the tube occluding the orifice. The plug prevents markers from passing through the orifice before the marker is to be placed at a desired location within a patient's body, prevents ingress of tissue into the bore of the tube, and allows markers to pass out of the orifice when marker delivery is desired. Guidance of a delivery tube to a desired location within a patient's body may include the use of an imaging device, with or without the use of a guide cannula. The plug may itself serve as a marker, and may be the sole marker. Markers may be detectable by ultrasound, X-ray, magnetic resonance imaging, and other imaging devices, and may include bioactive elements.

    摘要: An electrosurgical biopsy device includes a stylet and a cannula movably mounted on a base. The stylet has a shaft with a head at its distal end and a stylet ablation element extending distally from the head. The stylet shaft is disposed through the cannula for axial translation therein between withdrawn and extended positions. The cannula has an opening at its distal end and a cannula ablation element adjacent the opening. Both ablation elements are activatable with energy that ablates adjacent tissue. A translation mechanism controllably moves (a) the stylet between the withdrawn and extended positions and (b) the cannula between a proximal position and a distal position relative to the base. In use, with the stylet in the withdrawn position against the distal end of the cannula, and with the stylet ablation element activated, the stylet and the cannula are pushed through the skin and the underlying tissue until the stylet head is adjacent a targeted tissue mass. Next, the stylet is extended distally from the distal end of the cannula so that its head penetrates the tissue mass. The cannula ablation element is then activated, and the cannula is pushed through the tissue mass toward the stylet head, thereby cutting a nullcorenull through the tissue mass that is captured as a tissue specimen within the distal end of the cannula. The cannula and the stylet are then removed from the patient's body.

    摘要: A method for forming a tissue cutting member includes: providing a single longitudinally oriented opening in a side wall in a flared distal section of a distal tubular portion which radially opens to a lumen of the distal tubular portion, the single longitudinally oriented opening having an open distal end and extending from a closed proximal end to the open distal end; and providing a relief opening at the closed proximal end of the single longitudinally oriented opening, the relief opening having a transverse dimension larger than a transverse dimension of the single longitudinally oriented opening adjacent the relief opening, the single longitudinally oriented opening diverging from the closed proximal end to intersect a trailing cutting edge of a beveled front face of the inclined distal tip of the distal tubular portion and facilitating formation of the outwardly flared distal tubular portion.

    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 90° with respect to the longitudinal axis of the tissue cutting member.

    摘要: An intracorporeal marker delivery system includes a delivery device including a delivery cannula and a plunger. The delivery cannula has an inner lumen, a distal tip, and a discharge opening in communication with the inner lumen. A radiographically detectable marker having a fibrous-body and a radiographically detectable marker element coupled to the fibrous body is disposed within and pushable by the plunger through the inner lumen of the delivery cannula. An MRI detectable distal tip plug is disposed at least in part within a distal portion of the inner lumen distal to the radiographically detectable marker, and configured to partially occlude the discharge opening in the delivery cannula. An ultrasound detectable short term marker is interposed between the radiographically detectable marker and the MRI detectable distal tip plug in the inner lumen of the delivery cannula.

    摘要: The invention is directed to tissue cutting members and biopsy devices with such tissue cutting member for separating a tissue specimen from a patient's body at a target site. The tissue cutting member is slidably disposed within an inner lumen of an elongated probe member of the biopsy device to cut a tissue specimen drawn into the interior of an outer cannula of the biopsy device through a tissue receiving aperture in the probe. The tissue cutting member has a tubular distal portion with a distal tip having an outer tissue cutting edge, an inner tissue receiving aperture, and a longitudinally oriented opening with a closed proximal end and open distal end which opens to the inner tissue receiving aperture to facilitate flaring of the distal tubular portion. The cutting member has at least one opening in a wall of the tubular portion to maintain a vacuum during use.
