摘要： PROBLEM TO BE SOLVED: To provide an expandable device for proximately irradiating an internal tissue.SOLUTION: This invention relates to a device 10 for delivering a proximate irradiation to a target tissue region, having a proximal end 32 and a distal end 34 each sized to enter between tissues and an elongated body supporting two or more elongated members having pathways for receiving a radiation source. The elongated members can move between a folded structure and an expanded structure. During use, a tube passing the tissue is formed, and the elongated body supporting the elongated members is brought through the tube forward to a target position with the folded structure of the elongated members. The elongated members are directed to the expanded structure at the target position so as to, for instance, introduce one or more radiation sources along the pathways, thereby delivering the radiation and treating the tissue in the target position. This device is characterized by preventing an excess expansion and/or facilitating a prompt folding of the elongated members.

摘要： Systems and methods are provided for identifying or locating a tag within a patient's body that include a probe that transmits synchronized electromagnetic signals, e.g., RF energy, and optical signals, e.g., infrared light pulses into the patient's body, whereupon the tag converts the optical signals into electrical energy to open and close a switch in the tag to modulate signals, e.g., backscatter signals, transmitted by the tag in response to the electromagnetic signals. For example, the tag may include photodiodes coupled to the switch that transforms the optical signals to alternately short the antenna to modulate the backscatter signals. Alternatively, the tag may include a smart circuit that harvests electrical energy from the optical signals to power the smart circuit and/or modulate the backscatter signals, e.g., to include data related to the tag and/or alternate the tag between an information mode and a distance mode.

摘要： Markers, probes, and related systems and methods are provided for localizing locations within a patient's body, e.g., a lesion within a breast. The marker includes an energy converter e.g., one or more photodiodes, for transforming light energy striking the marker into electrical energy, a storage device coupled to the energy converter for storing the electrical energy, a threshold element that closes a switch when the electrical energy reaches a predetermined threshold to discharge the electrical energy and cause the antenna to transmit a radio frequency (RF) signal. The system includes a probe that transmits light into the patient's body and a processor that correlate the frequency of the RF signals to a distance from the probe to the marker.

摘要： Devices, systems, and methods used to deploy a localization device into a target lesion are disclosed. The system includes a delivery device configurable in a ready-to-deploy state and a deployed state. When the delivery device is in the ready-to-deploy state, biased engagement members are engaged with proximal detents of a handle of the delivery device. When the delivery device is in the deployed state, the biased engagement members are engaged with distal detents. The delivery device is transitioned from the ready-to-deploy state to the deployed state by distal displacement of a plunger relative to the handle. The localization device is deployed from a cannula of the delivery device into the target lesion when the delivery device transitions from the ready-to-deploy state to the deployed state.

摘要： Markers, microwave probes, and related systems and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The marker includes an energy converter e.g., one or more photodiodes, for transforming energy pulses striking the marker into electrical energy, a switch, e.g., FET, coupled to the photodiodes such that light from a probe cause the switch to open and close. A pair of antenna wires are coupled to the switch to provide an antenna, the switch configured to open and close when light strikes the photodiodes to modulate signals from the probe reflected by the antenna back to the probe to identify the location of the marker. The marker also includes an electro static discharge (ESD) protection device coupled to the switch to provide protection against an electrostatic discharge event.

摘要： Probes and related systems and methods are provided for localizing markers implanted within a patient's body. The probe includes an antenna assembly adjacent a distal end thereof including a ceramic base including a planar distal surface and four proximal surfaces extending at an angle relative to a longitudinal axis of the probe to define a generally pyramidal shape. The base includes antenna elements on the proximal surfaces and radial slots between adjacent proximal surfaces to substantially isolate the antenna elements from one another. A controller is coupled to the antenna elements for transmitting signals into a patient's body and receiving reflected signals reflected from a marker implanted within the patient's body to identify and/or localize the marker.

摘要： Brachytherapy treatment apparatus are provided that include an elongate core member, a plurality of expandable catheters or other elongate members and a balloon or other expandable member on a distal portion adjacent the core member. Each catheter includes a distal end coupled to the core member distal end, a proximal end movable relative to the core member, and a lumen extending between the proximal and distal ends for receiving a source of radiation therealong. The balloon is expandable independently of the catheters such that the balloon may be expanded after expanding the catheters, e.g., to facilitate imaging and/or dose planning. Optionally, a working channel may be provided for receiving an aspiration catheter or other instrument or at least one of the catheters may include an aspiration lumen and one or more ports, e.g., for aspirating material from a region surrounding the distal portion.
