  • Patent number: 10773100
    Abstract: Methods and devices are disclosed for treating a patient with an unruptured saccular aneurysm that is not associated with an arteriovenous malformation, wherein ionizing radiation is delivered to the brain of a patient through stereotactic radiosurgery. The radiosurgery may be performed with a Gamma Knife stereotactic radiosurgery apparatus, LINAC device such as CYBERKNIFE® stereotactic radiosurgery apparatus, or particle-beam device. The treatment impedes a natural progression of the aneurysm towards rupture and may actually obliterate the aneurysm. The treatment plan may be based in part on measured geometric properties of the aneurysm or on physical aneurysm properties such as permeability, wall thickness, wall motion, the presence of macrophages, shear stress, and flow velocities. The methods may be used in conjunction with endovascular coil embolization.

  • Patent number: 10271973
    Abstract: A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

  • Patent number: 10231625
    Abstract: Systems and methods are provided for a catheter-based system of image-guided internally-administered treatment of medical conditions such as, for example, pancreatic cancer. A distal end of a catheter is positioned at a target site inside a patient's body. An imaging probe extended through the catheter collects image data of patient tissue at the target site. The image data is processed and a treatment plan is developed. A radiation source positioned at the distal end of the catheter without removing the catheter. In this way, images collected at the target tissue site can be used to develop a treatment plan and to guide the localized positioning and operation of a treatment device at the same internal tissue site—thereby providing higher resolution imaging than external-based imaging modalities and reduced exposure to radiation as compared to externally applied radiation therapies.

  • Patent number: 10213335
    Abstract: Methods and apparatus for the treatment of a body cavity or lumen are described where a heated fluid and/or gas may be introduced through a catheter and into treatment area within the body contained between one or more inflatable/expandable members. The catheter may also have optional pressure and temperature sensing elements which may allow for control of the pressure and temperature within the treatment zone and also prevent the pressure from exceeding a pressure of the inflatable/expandable members to thereby contain the treatment area between these inflatable/expandable members. Optionally, a chilled, room temperature, or warmed fluid such as water may then be used to rapidly terminate the treatment session.

  • Patent number: 10201716
    Abstract: Apparatus for delivering brachytherapy to a target tissue region includes an elongate body including a proximal end, a distal end sized for introduction into a tissue tract and carrying a plurality of elongate members including pathways for receiving a source of radiation. The elongate members are movable between collapsed and expanded configurations. During use, a tract is created through tissue, and the elongate body carrying the elongate members is advanced through the tract into a target location with the elongate members in the collapsed configuration. The elongate members are directed to the expanded configuration at the target location, and radiation is delivered to treat tissue at the target location, e.g., by introducing one or more radiation sources along the pathways.

  • Patent number: 10182868
    Abstract: Electromagnetic transponders as markers are used to localize and guide orthopedic procedures including: knee replacement, hip replacement, shoulder replacement, damaged bone reconstruction, and spine surgery, and more particularly, to guide orthopedic surgical navigation and alignment techniques and instruments. For example, the marker could further be used in any number of guides or templates that attach to the bony anatomy; such as a surgical guide, cutting guide, cutting jig, resection block and/or resurfacing guide. Further, the marker could be incorporated into an existing intramedullary guide rod for a femur and an extramedullary guide rod for a tibia in a knee replacement surgery; or into an external surgical guide system, or the marker could eliminate the need for an external template altogether. According to yet another anticipated use of the tracking system, the marker could be used in conjunction with or replace an optical alignment system.

  • Patent number: 10143852
    Abstract: The invention relates to a determination apparatus for determining the pose and shape of an introduction element like a catheter within a living being, wherein the introduction element is adapted to be used by a brachytherapy apparatus for introducing a radiation source close to a target object to be treated. A position determination element like guidewire with an electromagnetic tracking element is introduced into the introduction element such that it is arranged at different locations within the introduction element, wherein the positions of the position determination element within the introduction element are determined. The determined positions are then acquired depending on the determined positions for determining the pose and shape of the introduction element within the living being. This can lead to a determination procedure with reduced user interaction, thereby simplifying the determination procedure for the user.

  • Patent number: 10092775
    Abstract: The invention provides for a medical instrument (400, 500, 600, 700) comprising a magnetic resonance imaging system (404) and an external beam radiotherapy system (402) for irradiating a target zone (438) of a subject with a beam (442) of ionizing radiation within the imaging zone. The medical instrument further comprises a processor (448) for controlling the medical instrument. Execution of instructions cause the processor to: acquire (100, 200) first magnetic resonance data (458); reconstruct (102, 202) a first magnetic resonance image (460) from the first magnetic resonance data; receive (104, 204) planning data (462), wherein the planning data specifies a spatially dependent radiation dose for the target zone; register (106, 206) the planning data to the first magnetic resonance image; and calculate (108, 208) an external beam dosage plan (468) and a brachytherapy dosage plan (468) using the spatially dependent radiation dose and the first magnetic resonance image.
