  • Patent number: 10802265
    Abstract: There are provided a lesion part volume measuring method and an endoscopic diagnostic apparatus capable of easily detecting the volume of a lesion part without using a special treatment instrument. This problem is solved by detecting the position of a distal end portion of a scope hood from an image captured by an endoscope to which the scope hood is attached, finding the volume of the internal space of the scope hood, which is formed by the scope hood and the distal end surface of an insertion part, from the position of the distal end portion of the scope hood and the model of the endoscope and/or the model of the scope hood, and injecting water into the scope hood and detecting the volume of a lesion part from the difference between the water injection amount and the volume of the internal space of the scope hood.

    Abstract: At the present time, physicians often treat patients with atrial fibrillation (AF) using radiofrequency (RF) catheter systems to ablate conducting tissue in the wall of the Left Atrium of the heart around the ostium of the pulmonary veins. These systems are expensive and take time consuming to use. The present invention circular ablation system CAS includes a multiplicity of expandable needles that can be expanded around a central axis and positioned to inject a fluid like ethanol to ablate conductive tissue in a ring around the ostium of a pulmonary vein quickly and without the need for expensive capital equipment. The expansion of the needles is accomplished by self-expanding or balloon expandable structures. The invention includes centering means so that the needles will be situated in a pattern surrounding the outside of the ostium of a vein. Also included are members that limit the distance of penetration of the needles into the wall of the left atrium.

  • Patent number: 8961423
    Abstract: Ultrasound catheter devices and methods of the present invention generally provide for ablation and/or disruption of vascular occlusions. An ultrasound transmission member, such as a wire, transmits vibrational energy from an ultrasound transducer to a distal head of the catheter to disrupt vascular occlusions. An absorber member is disposed on or around the ultrasound transmission wire at a location adjacent the sonic connector of the catheter. The absorber member absorbs heat, vibrations, and/or the like from the ultrasound transmission wire at or near the area where the transmission wire is coupled with the sonic connector. The absorptive function typically slows the process of wear and tear on the transmission wire, thus extending the useful life of the ultrasound catheter.

  • Patent number: 8012096
    Abstract: The present invention contemplates a surgical device for both ablating a channel in a patient's tissue and also delivering a therapeutic agent. The device includes an elongated multi-lumen tube, an elongated tissue ablating assembly, and a therapeutic agent delivery assembly. The therapeutic agent is capable of being delivered into the channel and/or to the surrounding tissue. The device may further include a second multi-lumen tube also capable of delivering therapeutic agents. Although suitable for many operations, the device is particularly well suited for transmyocardial revascularization operations. The present invention also contemplates a procedure for using such a surgical device to ablate a channel in a patient's tissue and also deliver a therapeutic agent.

  • Patent number: 7981041
    Abstract: A needle biopsy guide system is disclosed for attachment to an endoluminal ultrasound probe or like sonographic instrument. The device includes a biopsy-guide attachment that allows for trocar catheter placement for abscess drainage or like procedures, using the transvaginal or transrectal route under sonographic control. The device has a base portion, which is attachable to an ultrasound probe. A removable retainer is provided that slides into the base unit to hold a biopsy needle in place. A physician may locate the target area in the body with the ultrasound probe, insert the biopsy needle into the target area, and then remove the insert (retainer) from the base unit and ultrasound probe, and leave the biopsy needle in place in the body.

  • Patent number: 7976483
    Abstract: A catheter system is disclosed. The catheter system includes a catheter body having an external surface and an ultrasound transducer having a side between a first end and a second end. A first medium is positioned adjacent to the first end of the ultrasound transducer and a second medium is positioned adjacent to the external side of the ultrasound transducer. The second medium is harder than the first medium to encourage flexibility of the catheter body adjacent to the first end of the ultrasound transducer and efficient transmission of ultrasound energy from the external side of the ultrasound transducer.

  • Patent number: 7967763
    Abstract: An apparatus and method for treating subcutaneous tissues using acoustic waves in the range of low acoustic pressure ultrasound waves is disclosed. The method includes injections of enhancing agents, wherein disruption of subcutaneous tissues and subcutaneous cavitational bioeffects are produced by ultrasound waves having a power that will not produce tissue cavitation in the absence of the enhancing agents. The apparatus and method of use is useful for treatment of subcutaneous abnormalities including cellulite, lipomas, and tumors.

  • Patent number: 7870505
    Abstract: A graphical user interface for use in phacoemulsification surgical systems that allows a user to select different pulse modes by touching portions of the display screen. The user interface includes first and second display elements. One display element includes a representation of the on-time of the pulses, and the other display element includes a representation of the off-time. The representations show how the on-time and off-time change relative to a position of a controller, such as a foot pedal. The representation show a constant time, or that a time increases or decreases as the foot pedal is pressed. To select a pulse mode, a user can scroll through different pulse representations by touching the screen at the display elements. The selected pulse mode can be continuous, pulse, burst, or a combination or derivation thereof.

  • Patent number: 7806892
    Abstract: An ultrasound medical treatment system includes an end effector insertable into a patient. The end effector includes a tissue-retaining device. The tissue-retaining device includes a first tissue-retaining member having an ultrasound medical-treatment transducer and includes a second tissue-retaining member. The first and second tissue-retaining members are operatively connected together to retain patient tissue between the first and second tissue-retaining members and to release patient tissue so retained. In one example, the second tissue-retaining member has an ultrasound reflector. In the same or a different example, the ultrasound medical-treatment transducer is an ultrasound imaging and medical-treatment transducer.

  • Patent number: 7736317
    Abstract: An ultrasound transducer array (408) includes at least one transducer element (412) having a first (604) and second (606) portions separated by an acoustical discontinuity (520). The first portion (604) has the desired length to form a half-wave k31 resonance, while the second portion (606) has a resonant length for an undesired very low frequency out-of-band k31 resonance. The thickness of the transducer element (412) is designed for k33 half-resonance. Given the design, the transducer element (412) can operate and provide for both forward-looking (514) and side looking (512) elevation apertures. A method is also disclosed for using the disclosed ultrasound transducer (412) in ultrasound imaging.
