摘要:
Apparatus and methods for performing glandular reduction are described. In an example embodiment, an apparatus includes a needle-like probe containing a scintillation detector for converting gamma and x-rays emitted from a radio-labeled gland into photons that are then carried from the probe through a fiberoptic cable to a photodetector, and a therapy element for causing selective tissue destruction by directing energy toward the radio-labeled gland.

A method and apparatus for detecting and optionally treating metabolically unstable or active atherosclerotic plaque is provided. The patient is given an I.V. solution containing a radioactive tracer which specifically accumulates in these plaques. A miniaturized radiation detector for local radioactivity imaging and detection is applied directly within the arterial lumen. The radiation detector identifies and differentiates the active, unstable plaque from the inactive, stable plaque. Treatment may optionally be provided through any of three forms, including opening the vessel by mechanical expansion, removing the plaque by mechanical ablation, or delivering a metabolism-altering agent to the affected site.

In the field of radioimmunoguided surgical system instrumentation there is described and claimed a hand-held probe with a disposable power source as well as a visually perceptible indicator of detected counts of radiation. Also disclosed is a system comprising the hand-held probe and an instrumentation console. The handle includes a probe link that transmits a message containing gamma data relating to the low-level electrical signal. The instrumentation console may include a housing, a console link to receive the message transmitted by the probe link, a receiver electrically coupled to the console link to convert the message to corresponding electrical display signals, and a visually perceivable display electrically coupled to the receiver to convert the electrical display signals to a visually perceivable display relating to the amount of radiation detected.
摘要:
The present invention is directed to a miniaturized biosensor and nanotechnology which is embedded in a variety of medical devices which can be used for real-time device location tracking and analysis, for the purpose of optimizing device positioning both at the time of initial placement and throughout its clinical use (i.e., device continuum). The continuously acquired device-specific standardized data is then transmitted through wireless communication networks to provide continuous feedback and alerts to authorized clinical providers as to device positioning, clinical performance, and presence of pathology.
摘要:
The present invention relates to devices for detection of active atheromatous plaque and/or thin-capped fibro-atheroma (“vulnerable plaque”) using selectively targeted radiolabeled compositions, such as beta-emitting compositions.

The present invention relates to devices for detection of active atheromatous plaque and/or thin-capped fibro-atheroma (nullvulnerable plaquenull) using selectively targeted radiolabeled compositions, such as beta-emitting compositions.
摘要:
An apparatus for detecting a locating medium in tissue includes a probe, and a console. The probe includes a handle and a detector disposed on a distal end of the probe. The console is in communication and includes a display. The display has a first graphical representation and a second graphical representation. The first graphical representation is configured to depict a count real-time count based on a signal from the detector. The second graphical representation is configured to depict a target count.

Provided herein are an apparatus, system, and method for a medical diagnostic and imaging forceps for determining the pathology of tissue in vivo during surgery, endoscopy, laparoscopy, or other medical procedure, the forceps comprising a platform for analyzing tissue pathology inside the body by way of sensors including without limitation conductivity, optical, tracking, and x-ray sensors.
摘要:
A shaped medical balloon is provided that has a conforming shape, yet is inexpensive to manufacture, wherein a central portion of the balloon is folded inside and welded together at the fold and is further welded to said lumen, thus creating a conforming depression in the surface of said balloon at the central portion.
摘要:
The present invention relates to methods for selectively targeting Photodynamic Therapy (nullPDTnull) to inflammatory components of vulnerable plaques. As such, the present invention provides methods for the identification of vulnerable plaques, as well as methods to treat vulnerable plaques by selectively targeting and/or eliminating the inflammatory components of vulnerable plaques. The invention further relates to a specially designed intravascular device that delivers excitation light to the plaque surface inside the artery and receives emitted fluorescence light when a fluorescent signal is detected.
