A guide wire deployment system that can be utilized as a pre-surgical procedure without the need for radiology imaging. The clip marker would include light and sonic sensors to determine angular orientation and distance from the needle. Wireless communication between the handheld insertion device and the clip marker would provide information to guide the needle to the clip marker location. The guide wire would then be pushed from the needle and laid in a path to outside the patient.

A lumpectomy knife set including a main knife having at least one first planar wall extending between an upper edge and a knife edge with the at least one first planar wall defining a first geometric shape about a first through opening. A margin knife has at least one second planar wall extending between an upper edge and a knife edge with the at least one second planar wall defining a second geometric shape about a second through opening larger than the first through opening. The second geometric shape complements the first geometric shape such that the margin knife is concentrically positionable about the main knife with a margin gap between the main knife and the margin knife.

Described herein are devices for placement in surgically created soft tissue spaces, potential spaces, or cavities. The implantable devices generally include a bioabsorbable body having an open framework that facilitates attachment of tissue thereto in a manner that helps avoid post-surgical deformities. Methods for using the implantable devices in oncoplastic surgery are further described.

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.

An embodiment in accordance with the present invention provides a handheld cryoprobe for use in percutaneous cryotherapy of tumorous masses. It includes a probe attached to a CO.sub.2 gas dispensing backend. The probe has specifically optimized parameters designed for use with CO.sub.2 gas and is made out of a partially hollowed and threaded aluminum rod providing maximum heat exchange. The system backend regulates flow of compressed CO.sub.2 gas while throttling and cooling the gas coolant to the cytotoxically low temperatures necessary for targeted tumor cell death. Additionally, the incoming initial stream of CO.sub.2 gas is throttled by the Joule-Thomson nozzle on the backend. The low temperature exhaust gas is then used to pre-cool all subsequent incoming gas, resulting in an even lower temperature at the probe tip, which provides a positive feedback loop, continually decreasing the gas's temperature. The temperature drop is caused by the Joule-Thomson effect.

A method of operating a device (1) for treatment of a tissue (6) of a living being and such a device (1) including a transducer (2) comprising at least two subtransducers (2, 2), each for emitting a sub-beam (8) of ultrasound waves, preferably high intensity focused ultrasound waves, for irradiating the tissue (6). Each of the sub-beams (8) is focused on or focusable onto a focal point (F). In order to reduce skin burns, the intersection Area (A.sub.si) of a skin surface (7) for each sub-beam (8) is evaluated and a power (P.sub.si) and/or a duration (t.sub.si) of the irradiation, for every sub-transducer (2, 2), is determined as a rate of the total power (P.sub.total) or duration (t.sub.total) depending from the evaluated intersection area (A.sub.si).
