摘要： An instrument for implanting radioactive and/or thermal seeds in body tissue for radiation and/or heat therapy comprises a tubular hypodermic needle barrel affixed to a pistol-grip shaped handle incorporates a reciprocally movable push rod for stripping one such seed from a cartridge containing a plurality of seeds and advancing it to the end of the barrel. Actuation of a trigger in the pistol grip handle causes the barrel to retract relative to the push rod, causing the seed to be deposited in the channel in the body tissue created by the original puncturing thereof by the instrument's barrel.

摘要： A soft plastic Brachy tube cap has a tubular body with one closed and one open end. The body's internal bore is sized so that the end of a Brachy tube fits snugly within the body when inserted through the open end. A pair of spaced locking rings integral with the body are adapted to fit about the Brachy tube. If the cap receives pressure towards removal, the two rings deform, through the pressure on the connecting straps, which results in reducing the bore radius and causes them to bend tighter on the Brachy tube. This prevents displacement of the caps.

摘要： A novel brachytherapy device is formed from a hollow-tube-shaped seed-substrate, allowing the easy association of the device with suture material. This shape minimizes the chance of migration of implanted seeds due to better attachment to tissue. The distribution of the radioactive material on the exterior surface of the tubular device provides a relatively uniform radiation field around the hollow-tube-shaped brachytherapy seed source. Brachytherapy devices are described that are inherently radioactive. Also disclosed are devices that can be rendered radioactive by the transmuting effects of neutron irradiation. Brachytherapy devices are discussed that facilitate medical application and improve safety for patients and medical personnel.

摘要： A minimally invasive intravascular medical device for providing a radiation treatment in a body passageway such as a coronary vessel of the vascular system. The device includes a flexible elongated member having distal and proximal portions. The distal portion is percutaneously insertable into a vessel and includes a distal end that is directable through the vessel to the treatment site. A radiation source is attached about the distal portion for delivering a radiation treatment to the walls a vessel having a stent positioned thereagainst. The distal portion of the elongated member includes a wire coil positioned about the tapered distal end of a mandril wire. The combination of the wire coil and the tapered distal end of the mandril wire provides variable flexibility to the distal portion of the device. The distal portion also has a predetermined curvature for directing the distal end of the device through the vessel. A safety wire is also extendable through the passageway of the wire coil to provide further flexibility to the distal portion. The radiation source is fixedly positioned about either the tapered distal end of the mandril wire or the safety wire in the passageway of the wire coil. An annular recess is included about the tapered distal end of the mandril wire to fixedly position a source of radioactive material therein.

摘要： A method of forming implantable low dose solid radioactive segments of desired lengths sealed against end leakage of radioactive particles, for use in brachytherapy of malignant tumors. The segments are separated from a single continuous elongate assembly of composite material which includes a continuous solid radioactive elongate core at least partly composed of iridium, sufficiently brittle to break cleanly when cut transverse to its longitudinal axis, encased along substantially its entire longitudinal surface in a sheath having a predetermined thickness and composed of substantially pure platinum or other metal which is malleable relative to the hardness of the core and, when irradiated, has a half-life much shorter than that of the core. When a radioactive segment of selected length is needed for use as a brachytherapy implant, the continuous assembly is cut transversely to provide the selected length, using a pair of scissors having opposed blunt blades, by bringing a portion of the assembly transversely between the blunt blades and thereupon exerting a cutting force on the assembly lying therebetween to break the core cleanly at that point while squeezing the sheath firmly about the newly cut end of the core to encapsulate and substantially seal it within the sheath against radioactive leakage at the newly cut end.

摘要： The incidence of restenosis after angioplasty is reduced by exposing the potentially stenotic site to radiation from a source within the same vascular structure in which the site is located. The radioactive source can be mounted at the distal end of a guidewire, or in a balloon catheter, or on a balloon expansible stent, and is inserted through the vascular structure to the site to be exposed.

摘要： Method and apparatus is disclosed for treating tissue interstitially with multiple modalities of treatment. The apparatus comprises a semi-rigid elongated member that is implanted interstitially in the malignant tumor. A hollow passageway is longitudinally positioned in the member for positioning one or more modalities inserted or positioned therein. The elongated member is coated with another modality such as a carrier substance that is responsive at a temperature above normal tissue temperature for releasing a carried substance such as a therapeutic anti-cancer drug. Within the elongated member, an electrical heater element for one modality produces heat when energized for heating the probe, the carrier substance, the anti-cancer drug, and the surrounding tissue. A second modality such as a source of radiation is inserted in the passageway after the probe is interstitially implanted. A trocar stylet is initially inserted in the passageway to implant the probe. When the probe is implanted, the trocar stylet is removed, and the heater element and/or source of radiation is inserted into the passageway. The several modalities combine in a synergistic manner to provide an overall treatment that has an effectiveness level greater than the sum of the individual modalities.

摘要： A drivable radioactive source capsule is provided which comprises a tubular body containing therein a plurality of radioactive sources. The said tubular body has a first end and a second end which is a terminus of the tubular body. A plug has an elongated closure portion with the diameter of the closure portion being substantially equal to the inside diameter of said tubular body. The closure portion is disposed within the tubular body through the second end thereof and is attached to the second end of the tubular body. The plug has a connection portion adjacent the closure portion with the diameter of the connecting portion being substantially equal to the outside diameter of the tubular body. An elongated flexible drive cable is connected to the connection portion of the plug. By this arrangement, radioactive sources may be placed in the tubular body and the body is closed by disposing the closure portion of the plug into the second end of the tubular body and attaching the closure portion to the second end of the tubular body.
