The present invention is directed to tissue removal devices and methods. A tubular element having an open distal end is advanced into tissue so that tissue enters the tubular element. The tissue, which entered the tubular element is cut to separate the tissue from the surrounding tissue. The tissue is then transported proximally by the cutting element or a separate transport element.

Methods and devices for removing tissue from a patient

Devices and methods for cutting and collecting a specimen from a mass of tissue. The device may include an integrated cut and collect assembly. The integrated cut and collect assembly includes a cutting portion and a collection portion that includes a flexible membrane. The collection portion of the assembly is attached to the cutting portion thereof. The cutting portion is configured to cut the specimen from the mass of tissue and the collection portion is configured to collect the cut specimen and to encapsulate and isolate the cut specimen within the membrane to enable its safe retraction from the mass of tissue.

Methods and devices for cutting and collecting soft tissue

The device is used to remove tissue from a patient and to also place a marker in the patient. The device has an opening through which tissue enters the device. The tissue, which enters the opening is cut and the tissue is removed. The device may be used a number of times to remove a number of tissue masses. The device also includes a marker, which the user may release in the patient at the desired time.

Methods and devices for removing tissue from a patient and placing a marker in the patient

A method of cutting breast tissue for removal may include a step of providing a tissue cutting device having an elongate cutting element, the cutting element being movable between a bowed position and a retracted position, the cutting element having a radially outer side and a radially inner side. The tissue cutting device may be introduced into a breast and the elongate cutting element may be moved to the bowed position. A power source may be coupled to the elongate cutting element; and the cutting element may be rotated after the moving step so that the cutting element cuts the breast tissue. The radially outer side of the cutting element may have a larger surface area for transmitting energy to cut the tissue than the radially inner side.

The present invention is directed to tissue removal devices and methods. A tubular element having an open distal end is advanced into tissue so that tissue enters the tubular element. The tissue which entered the tubular element is cut to separate the tissue from the surrounding tissue. The tissue is then transported proximally by the cutting element or a separate transport element.

Devices and methods for collecting or cutting and collecting a specimen from a mass of tissue within a patient. The device may include a specimen collection assembly including a flexible membrane that isolates collected specimen from the surrounding tissue. The collection device may also include structures that draw the collected specimen toward the shaft and/or otherwise ease the insertion and retraction of the device and the collected specimen from the patient through a small incision.

An electrically activated surgical device includes a probe body, an active element and a structure for selectively electrically insulating and/or physically isolating the active element from the patient's tissue when the device is in use. The probe body defines an outer surface, a proximal end, a distal end and a window defined within the outer surface near or at the distal end. The active element is electrically connected to a power source and is configured to selectively assume a non-deployed configuration and a variable deployed configuration in which the active element at least partially emerges from the window out of the probe body. The insulating structure selectively insulates the active element from the patient's tissue when the device is inserted therein. In operation, a physician inserts the probe into the tissue, insulates the active element from the tissue (either before, during or after insertion of the probe), energizes the insulated active element using for example, radiofrequency (RF) power from the power source, and only then exposes the energized active element to the tissue. By insulating the active element during the energizing thereof, little or no current applied to the active element is dissipated in the patient's tissue, thus decreasing the time required to energize the active element and enabling lower and safer power levels to be applied to the active element during the energizing thereof.

Methods and devices for radiofrequency electrosurgery

Surgical devices include a selectively cutting and atraumatic distal tip that is configured to assume a first configuration in which cutting surface or surfaces thereof are effective to cut tissue and a second configuration in which the cutting surface or surfaces thereof are ineffective to cut tissue.
