Appl. No.:

8/889469

US Classification:

424111

Abstract:

A system for detecting and destroying living tumor tissue within the body of a living being. The system is arranged to be used with a tumor localizing radiopharmaceutical. The system includes a percutaneously insertable radiation detecting probe, an associated analyzer, and a percutaneously insertable tumor removing instrument, e. g. , a resectoscope. The radiation detecting probe includes a needle unit having a radiation sensor component therein and a handle to which the needle unit is releasably mounted. The needle is arranged to be inserted through a small percutaneous portal into the patient's body and is movable to various positions within the suspected tumor to detect the presence of radiation indicative of cancerous tissue. The probe can then be removed and the tumor removing instrument inserted through the portal to destroy and/or remove the cancerous tissue. The instrument not only destroys the tagged tissue, but also removes it from the body of the being so that it can be assayed for radiation to confirm that the removed tissue is cancerous and not healthy tissue.

Abstract:

A biopsy probe for detecting radiation emanating from a hidden source in a patient. The probe comprises a body member formed of a radiation blocking material and having a distal end portion and a proximal end portion. The proximal end portion is arranged to be held in the hand of a user. The probe comprises a radiation detector, e. g. , a scintillation crystal, located within the distal portion of body member, a first radiation transparent window located at the distal end of the body member confronting the detector and through which radiation may pass to the detector, and a passageway extending through the distal end portion of the body member centered in the window and the detecting means. The passageway is arranged to guide a thin instrument, e. g. , a biopsy needle, therethrough when the distal end portion is oriented in a direction toward the hidden source of radiation.

International Classification:

A61B 612

US Classification:

128654

Abstract:

An apparatus and method for producing audible signals, which are representative of the level of detected radiation from a probe, and which are statistically valid. The output of a radiation detector is a series of pulses, which are counted for a predetermined amount of time. At least two count ranges are defined by circuitry in the apparatus and the count range which includes the input count is determined. For each count range, an audible signal is produced which is audibly discriminable from the audible signal produced for every other count range. The mean values of each count range are chosen to be statistically different, e. g. , 1, 2, or 3 standard deviations, from the mean of adjacent lower or higher count ranges. The parameters of the audible signal, such as frequency, voice, repetition rate, and/or intensity are changed for each count range to provide a signal which is discriminable from the signals of any other count range.

International Classification:

G01T 1161

US Classification:

2503361

Abstract:

A collimating probe and methods of use for detecting, localizing, and mapping or imaging radiation emanating from a hidden source, such as within the body of a living being. The probe comprises a radiation detector and an adjustment mechanism for adjusting the solid angle through which radiation may pass to the detector. That solid angle is continuously variable. The probe is constructed so that the only radiation reaching the detector is that which is within said solid angle. By adjusting the solid angle from a maximum to a minimum while moving the probe adjacent the source of radiation and sensing the detected radiation, one is able to precisely locate the probe at the source of radiation. The probe can be used for diagnostic or therapeutic purposes. A receptacle is also provided to hold a specimen on the probe to detect the presence of radiation emanating therefrom.

International Classification:

US Classification:

25036310

Abstract:

A probe and collimator to be releasably secured thereto for use in detecting, localizing, and mapping or imaging radiation emanating from a hidden source, such as within the body of a living being. The probe comprises a small body arranged to be readily held in one's hand and a radiation detector located within the body. The probe's body includes a window located at its distal end over the detector. The collimator comprises a cylindrical member adapted to be snap-fit onto the distal end of the probe body to reduce the solid angle of acceptance of radiation entering the window to a predetermined value less than that if the collimator was not in place on the probe. The collimator includes a central bore having an air vent and at least one recess extending about the inner periphery thereof and in which is located a resilient locking member, e. g. , an O-ring. The body at the distal end of the probe includes at least one recess extending about the outer periphery thereof and into which the locking member is snap-fit to releasably secure the collimator to the probe.

US Classification:

600/407000

Abstract:

A probe or sheath for use on a probe for detecting and removing radioactively tagged tissue, e.g., a sentinel lymph node, within the body of a living being. The probe or sheath and probe is arranged to be inserted through a small percutaneous portal into the patient's body and is movable to various positions adjacent the tagged tissue to detect the presence of radiation therefrom so that it can be positioned immediately adjacent that tissue to ensnare or trap that tissue. The probe or sheath and probe can then be removed from the being's body, carrying the tagged tissue with it. The probe may be constructed to make use of a scintillation crystal, a collimator, adjustable or fixed, and a backshielding lightpipe. A blunt dissecting device is provided as part of the sheath or as part of the probe itself to aid in separating the tagged tissue from adjacent tissue without injury to the adjacent tissue. The probe may be a fully integrated, self-powered unit.
