  • Patent number: 11224437
    Abstract: Soft embolic implants exhibiting secondary shapes are disclosed. Some of the embolic implants exhibit progressively increasing softness from the distal end to the proximal end of the coil. The embolic implants have a primary coil, an optional second coil, a shape wire, and a stretch resistant fiber disposed in the lumen of the primary coil. An optional distal support wire is also disclosed. The embolic implants include a proximal constraint assembly configured to be releaseably retained by a delivery device. Disposed near each end of some of the implants are elliptical hole washers through which the shape wire and the stretch resistant fiber are threaded. The embolic implants have a primary, linear configuration for delivery through an implant tool, and a secondary configuration after deployment from the implant tool. The secondary shape can be J-shaped, helical, spherical, complex, or a combination of shapes.

  • Patent number: 11207151
    Abstract: A marker for use in the lung of patients for marking the position of a lesion in the lung, wherein the marker comprises a self-expandable structure capable of self-expanding when released from a constricting device so as to implement marking function. Because the marker for use in the lung of a patient employs the self-expandable structure, when the position of a lesion is detected during a lung examination, the marker can be delivered to the position of the lesion via a catheter or a delivering device and substantively pressed and fixed by the lung when expanded at the lesion positions; as such, the lesion position can be located quickly by a surgeon during a surgery, the surgery time is shortened, the area of resection is reduced, and the post-surgery quality of life is improved for a patient.

  • Patent number: 11185600
    Abstract: The present invention relates to contrast agent enhanced medical ultrasound imaging. In particular, the contrast agents provided are useful for cell imaging and cell therapy, as well as in vivo targeting, drug delivery and perfusion or vascular imaging applications. More specifically, it provides a particle comprising a fluorinated organic compound and a metal. Such particles may be advantageously employed in qualitative or quantitative imaging such as acoustic imaging including photoacoustic and ultrasound imaging, MRI imaging, such as 19F imaging, 1H imaging including T1 and T2 weighted imaging, SPECT, PET, scintigraphy, fluorescence imaging and optical coherence imaging and tomographic applications. This may then be employed in cell labeling, microscopy, histology or for imaging vasculature or perfusion in vivo and in vitro.

  • Patent number: 11147562
    Abstract: An aneurysm treatment system that includes an embolic implant, a delivery system, and an introducer sheath that are collectively designed so that the combination of the introducer sheath and the delivery system can be used as a deployment apparatus for the embolic implant. The delivery system can have a pull wire, a delivery tube, and an interference feature attached to the pull wire and positioned near a proximal end of the delivery tube. Rather than being discarded, the introducer sheath can be moved proximally over the delivery tube until it engages the interference feature. To deploy the implant, the introducer sheath can be pressed against the interference feature, causing the interference feature to move proximally in relation to the delivery tube, thereby proximally pulling the pull wire to which the interference feature is attached and deploying the implant.

  • Patent number: 11141045
    Abstract: A single-use electronic endoscope has a hub, a shaft extending from the hub, flexible or rigid as desired, and an expandable distal tip extending from the shaft. Within the distal tip, an image sensor provides a field of view external from the endoscope. Illuminating elements or light guides within the distal tip emit light to illuminate the field of view. The distal tip also has a variable profile working channel that permits tools to be passed from the hub and into the field of view. The expandable working channel changes cross-sectional shape from a generally noncircular shape to a shape to accommodate the cross-sectional shape of the tool when expanded.

  • Patent number: 11103373
    Abstract: The present invention is directed to a deployment system for an endoluminal device. The deployment system includes a confining sheath placed around a compacted endoluminal device. A deployment line is provided in the system. As the deployment line is actuated, the sheath retracts from around the compacted endoluminal device. Once the sheath is retracted from around the compacted endoluminal device, the endoluminal device is operable to expand. Any remaining sheath material is removed from the implantation site along with the deployment line.
