  • Patent number: 10758260
    Abstract: An ultra-sonic medical dissector includes a vibration generator and a wire that defines a cutting loop remote from a first end and a second end. The wire is coupled to the vibration generator in a cutting configuration, and a cutting surface is located on an inner curvature of the cutting loop. A vibration is generated by the vibration generator is transmitted to the cutting loop by the wire when the wire is in tension. The cutting loop can free an embedded end of a vena cava filter from a vessel wall to ease retrieval.

  • Patent number: 10729415
    Abstract: An implanted device, such as an inferior vena cava filter, that is partially embedded in soft tissue is retrieved by coupling a vibration device to the implanted device. The implanted device is disembedded from the soft tissue at least in part by generating a vibration with a vibration generator, transmitting the vibration along the vibration transmission apparatus to the implanted device, and vibrating the implanted device. The implanted device is then moved away from the embedding site. A medical device assembly includes the vibration generator, the implantable device and the vibration transmission apparatus.

  • Patent number: 10588637
    Abstract: A method of treating a vessel, such as sclerotherapy, includes moving a short balloon catheter to a position at which a compliant extra-luminal balloon is outside of the vessel at an occlusion site, and between the vessel and a non-compliant bearing surface. The vessel is occluded at the occlusion site by inflating the compliant extra-luminal balloon of the balloon catheter, and bearing an outer surface of the balloon against the vessel and the non-compliant bearing surface. The vessel is medically treated upstream from the occlusion site. The short balloon catheter includes a wire guide lumen.

  • Publication number: 20180228538
    Abstract: Tissue cutting systems and methods of tissue cutting are provided. In one example, the tissue cutting system includes a first device and a second device adapted for coupling to a power supply. The first device includes a conductive probe. The second device includes a conductive material, for example, as part of an expandable structure, having an outer surface area of conductive material that may be larger than a surface area of the conductive probe. The conductive probe and the conductive material are deployed along opposite sides of a body tissue, such as an aortic dissection flap. Selective electrical power is applied to the conductive probe and the conductive material to cut the body tissue.

  • Patent number: 9280777
    Abstract: An operations dashboard may be used to present recommended solutions to various challenges faced by a retail store that is part of an enterprise. In some implementations, a metrics engine may be used to track and diagnose challenges related to various performance metrics, such as inventory, pricing, customer satisfaction, and the like at one or more of the enterprise's retail store locations. The operations dashboard may, in certain embodiments, display one or more of the retail stores along with their corresponding diagnosed business challenges. A knowledge engine may be used to identify one or more solutions to the diagnosed business challenges, and the solutions may also be displayed on the dashboard. In some implementations, each of these solutions may have a corresponding recommendation score relating to the expected efficacy of the solution to solve the challenge.

  • Patent number: 7569018
    Abstract: An auditory pulse monitor for noninvasively detecting the amplitude of arterial pulses on a beat-by-beat basis. A light-weight optical sensor including a light source and photodetector is adapted for application to the skin surface of a subject over a tissue bed containing an arterial supply. The photodetector generates an output signal proportional to the amplitude of an arterial pulse, and an electronic circuit connected to the photodetector generates a signal having a frequency proportional to the photodetector output signal level. A speaker or other audio indicator connected to the electronic circuit generates an audible tone indicating the amplitude of the arterial pulse. Another aspect of the invention is an improvement in automated or automatic external defibrillators (AEDs). An AED is disclosed which optically detects arterial pulses after delivering a defibrillation shock and signals the need for CPR if it detects inadequate cardiac pumping following successful defibrillation.

  • Patent number: 7164938
    Abstract: An optical noninvasive vital sign monitor comprising a reflectance-type optical sensor within a pressurizable capsule retained by a headband, the capsule having an optically transparent or translucent inner wall adapted for placement against a subject's forehead. The optical sensor is mounted on the inside surface of the pressurizable capsule's inner wall, which contacts the subject's forehead during use, and includes a light source and a photodetector aimed toward the inside surface of the inner capsule wall. One embodiment of the vital sign monitor includes optical oscillometric circuit means responsive to an output signal from the optical sensor for determining systolic pressure, mean pressure and diastolic pressure during a transition in capsule pressure between a pressure greater than normal systolic pressure and a pressure less than normal diastolic pressure.

  • Patent number: 7014611
    Abstract: An oscillometric, noninvasive blood pressure monitor comprising an inflatable cuff adapted for placement around a body member, a pump for cuff inflation, a pressure transducer connected to the cuff, means for detecting oscillations in arterial pressure occurring during a transition in cuff pressure between a pressure greater than normal systolic pressure and a pressure less than normal diastolic pressure, and a blood pressure measurement circuit which is capable of determining the maximum amplitude (Am) of the oscillations, identifying mean cuff pressure (Pm) as the coincident value of the cuff-pressure signal from the pressure transducer, and determining systolic pressure as a function of both Am and Pm. In accordance with one aspect of the invention, the blood pressure monitor has an optical sensor including a light source and photodetector optically coupled to the body member proximate to the cuff.

  • Patent number: 6126686
    Abstract: A method for preparing vascular valves from submucosal tissue is described. Both bicuspid and tricuspid valve constructs are described. The bicuspid constructs can be formed with or without a supporting stent. The tricuspid constructs are formed by fixing submucosal tissue to a supporting stent, folding the submucosal tissue, and forming the valve commissures from the folded submucosal tissue by cutting along the folds. The artificial vascular valves are useful for replacing damaged or diseased valves of a warm-blooded vertebrate.
