  • Patent number: 12011151
    Abstract: Among other things, there is disclosed structure and methods for maintaining access to a location in the body while reducing or eliminating the potential for pulling an access device (e.g. a catheter) back through an opening. An introducer sheath includes a distal indented portion and a balloon, so that once placed in a desired location through tissue, the balloon can be inflated to anchor the sheath against retraction. In particular embodiments, structure and methods for accessing the pericardial cavity via the right atrial appendage are shown.

  • Publication number: 20230233065
    Abstract: Disclosed herein is a medical device including a camera including a movable member including an outer surface with a longitudinally-extending cross-sectional geometry configured to complement a longitudinally-extending cross-sectional geometry of a surface of a lumen in an elongate tube housing the movable member so as to prevent rotation of the movable member relative to the elongate tube. The device allows the operator to maintain visual orientation as the movable member is translated proximally and distally relative to the elongate tube.

  • Publication number: 20230079970
    Abstract: A method of treating a lesion in a gastrointestinal tract and an injectate system are provided. The method includes injecting a crosslinkable gel into a first tissue layer, the crosslinkable gel increasing a volume of the first tissue layer. The method also includes providing a crosslinker and resecting a portion of a first tissue layer having the increased volume away from a second tissue layer creating an exposed region in a remaining portion of the first layer and leaving a portion of the gel covering at least a portion of the exposed region. The injectate system includes a crosslinkable gel and a crosslinker where the crosslinkable gel and the crosslinker form a crosslinked gel having a compressive modulus of about 10-500 kPa.

  • Patent number: 11517710
    Abstract: Methods of modifying the luminal profile of a body vessel are described. An example method comprises advancing a cannula out of the distal end of a catheter disposed within the lumen of a body vessel of an animal and toward a target site on the wall of the body vessel; passing contrast dye through the cannula toward the target site; simultaneously continuing the advancing and passing until the distal end of the cannula punctures the inner layer of the wall of the body vessel at the target site; and passing a bulking agent through the cannula and into a space between connective tissue layers surrounding the vessel wall at the target site. Medical devices, medical device assemblies, and kits are also described.

  • Patent number: 11439384
    Abstract: Among other things, there are shown embodiments of locking mechanisms for holding sutures in tension. Such devices may be used with implants that use or require sutures, and are easily locked remotely. In particular embodiments, a lock includes a housing member, a pin member at least partially within the housing member, and a spring biasing the pin member into the housing member. The pin member includes a gripping portion, and has a retracted condition and a locked condition. When retracted, a suture can move through the housing member and around the gripping portion of the pin member. When locked, the gripping portion of the pin member engages the suture and presses it against the interior of the housing member.
