  • Patent number: 10441289
    Abstract: A valve (2) comprising: (a) membrane (50) and (b) a frame (10) in communication with the membrane so that the frame expands the membrane, the frame including: (i) a rod (4), (ii) a plurality of struts (12) connected to the rod at a distal end and extending generally radially outward as the struts extend away from the distal end and towards a proximal end; (iii) a plurality of anchors (30) that are in direct communication with the struts between the distal end and the proximal end, each of the plurality of anchors extending through an exit location (52) in the membrane.

  • Patent number: 10307243
    Abstract: A valve comprising: (a) a rod, (b) a plurality of struts in communication with the rod and extending generally radially outward away from the rod in a deployed state, the plurality of struts including at least: (i) a plurality of first struts that extend radially outward from the rod a first distance, and (ii) a plurality of second struts that extend radially outward a second distance from the rod, wherein the second distance is less than the first distance; and (c) one or more membranes that are in communication with the first struts, the second struts, or both.

  • Patent number: 10258376
    Abstract: A tool for manipulating a foreign body (e.g., a deployed medical device) can include an operative portion. The operative portion can be used to move the foreign body in the proximal and/or distal directions with respect to the removal/repositioning tool and/or the tissue surrounding the foreign body. In some embodiments, the tool can include a compressing portion that can be used to compress the foreign body as the foreign body is pulled by the operative portion in the proximal direction. The tool can further include a sleeve that can be used to transition the operative portion and/or compressing portion between an opened configuration and a closed configuration. In some embodiments, the tool can be used in conjunction with an endoscope to navigate the tool to the site of a foreign body within the body of a patient.

  • Publication number: 20190053906
    Abstract: A valve planning tool comprising: (a) a stem having a distal end and a proximal end, (b) an anchor indicator located at the distal end, and (c) a balloon located proximal of the anchor indicator, the balloon including: (i) a retracted state and (ii) a deployed state; wherein the balloon is inflatable from the retracted state to the deployed state and the balloon is substantially non-compliant so that the balloon is only inflatable to one size.

  • Patent number: 10201442
    Abstract: A valve loading system is provided that uses a valve loader to transfer a valve or other medical device from a storage cartridge into a deployment catheter. The valve or other medical device can be implanted or positioned within a patient using the catheter after the valve or other medical device has been compressed and loaded into the catheter using the valve loader. The process then can be repeated by using the valve loading system to load or introduce another valve or other medical device into the catheter.

  • Patent number: 10123788
    Abstract: A deployment catheter is described herein that preferably is configured to deliver a medical device such as a valve to a location in a patient such as a patient's airway. Preferably, such a deployment catheter is configured to be used in conjunction with a bronchoscope. In some embodiments, a locking lever is provided to reduce the likelihood of accidental deployment of the device, and which resets conveniently after use to as to permit multiple device deployments.
