  • Patent number: 10456595
    Abstract: A system for interventional brachytherapy for generating data to be used directly for therapy and/or for therapy planning includes a radiation source which irradiates tissue of a patient and one or more radiation detectors which detect radiation delivered to the patient and generate radiation dosage data indicative thereof. One or more position sensors determine the position of the radiation source and a localization unit, in communication with the one or more position sensors, generates position data indicative of the position of the radiation source. An image database stores one or more anatomical images of the patient. A dose calculation unit which co-registers the one or more anatomical images with the positional and radiation dosage data and generates dose monitoring data based on the co-registration.

  • Patent number: 10448994
    Abstract: A method for manufacturing a shaping structure having a generally helical profile and configured to support electrodes for delivering electric energy into a cylindrical lumen of a patient. The method comprises providing a mandrel with a circular cylindrical shape and forming a first hole in the mandrel along the elongate axis, such that opposing ends of a bore of the first hole emerge at the proximal end and at the distal end; forming a second hole in the mandrel to extend from the curved surface to connect with the first hole; wrapping a metal wire around the mandrel; and inserting opposing ends of the metal wire into the second and the third hole respectively, and threading the opposing ends of the metal wire until they emerge from the opposing ends of the bore of the first hole; finally, heating the mandrel and the wire.

  • Patent number: 10420732
    Abstract: The present invention relates to the design and development of a drug delivery nanoplatform that consists of nanoporous, multi-layer biodegradable polymeric (BP) thin films for controlled release of its payload. The method is used notably to synthesize nanoporous BP coatings as drug delivery vehicles exhibiting uniform nanopores with tailored characteristics for control of drug delivery and release. It enables the multiplex delivery of drugs that can be eluted at desirable time intervals in line with each medical need. Atomic Force Microscopy and Spectroscopic Ellipsometry are applied for determining nanoporosity, thickness, drug loading, structural properties, and quality of the BP films ensuring the quality control of the final product. The complete degradation of the polymers minimizes the toxicity within the human body and such nanoplatform can be used in a wide range of drug eluting and other medical implants and biomedical devices.

  • Patent number: 10413750
    Abstract: The disclosure describes devices and methods for asymmetrical irradiation at a body cavity or site, such as after removal of tissue, e.g. biopsy or cancer. One device includes a lumen which is off-set or off-settable from a longitudinal axis to increase the intensity of radiation received from a radiation source by a first tissue portion surrounding the body cavity and to reduce or minimize radiation received by a second tissue portion (e.g. healthy tissue) surrounding the body cavity.

  • Patent number: 10413381
    Abstract: An implantable tissue marker device is provided to be placed in a soft tissue site through a surgical incision. The device can include a bioabsorbable body in the form of a spiral and defining a spheroid shape for the device, the spiral having a longitudinal axis, and turns of the spiral being spaced apart from each other in a direction along the longitudinal axis. A plurality of markers can be disposed on the body, the markers being visualizable by a radiographic imaging device. The turns of the spiral are sufficiently spaced apart to form gaps that allow soft tissue to infiltrate between the turns and to allow flexibility in the device along the longitudinal axis in the manner of a spring.

  • Patent number: 10413318
    Abstract: Various embodiments of devices and systems comprising a polymer driveshaft for use in high-speed rotational medical procedures, e.g., atherectomy, are disclosed. Generally, the primary driveshaft for transferring torque and activating rotation of a tool attached thereto, e.g., an abrasive element, is constructed with at least a polymer outer and inner surface. In certain embodiments, the polymer driveshaft may comprise a metallic band for fixed attachment of a structure, e.g., an abrasive element, thereto. Various embodiments may comprise a coupler that connects a drive shaft connected with a prime mover, e.g., a turbine or electric motor, with the polymer drive shaft, the coupler comprising openings through the coupler wall to the inner diameter of the coupler to allow fluid flow to the inner diameter of the coupled polymer drive shaft.

  • Patent number: 10350433
    Abstract: Disclosed is a layer structure for epidermal radionuclide therapy (brachytherapy) of a patient comprising, from a patient's view, a proximal adherent layer for applying the layer structure on the skin surface to be treated of a patient; a flexible, transparent carrier layer that from a patient's view is located in a distal direction on the adherent layer; and at least one radionuclide-containing emission layer located on the carrier layer, the adherent layer and the carrier layer with regard to their components and thickness being formed such that they are essentially transparent for ? and ? radiation. The layer structure is suited particularly for radiotherapeutic treatment of the basal-cell carcinoma (BCC) and the squamous cell carcinoma (SCC). With the aid of the layer structure, geometrically complex skin lesions caused by a tumor, as occurring e.g. on the outer edge of the auricle, may be treated easily.

  • Patent number: 10346719
    Abstract: The present disclosure provides a magnetic resonance (MR) image analysis method for a patient who underwent radiotherapy. The method includes the steps: receiving an MR image set of a patient and a dose map of a radiotherapy plan; converting the dose intensity distribution of the dose map into the relative spatial positions in the MR image set; selecting a radiation dose and a radiation exposure region, wherein the radiation exposure region has radiation intensity being equal to or higher than the radiation dose; using the radiation exposure region to determine a region of interest (ROI) in the MR image set; classifying the voxels inside the ROI of the MR image set into different clusters according to the grayscale values of the voxels inside the ROI; and calculating the volume or ratios of the different clusters inside the ROI. The present disclosure also provides a method for evaluating risks of radiotherapy.
