  • Publication number: 20250049426
    Abstract: A vascular closure device is configured to seal a puncture in an artery or vein. The vascular closure device includes a deployment assembly having a proximal end and a distal end opposite the proximal end, a suture carried by the deployment assembly, and a footplate carried by the deployment assembly and coupled to the suture. The footplate is configured to exit the distal end of the deployment assembly for deployment in the puncture. The vascular closure device includes a retraction assembly coupled to the footplate, the retraction assembly configured to, after deployment of the footplate, retract the footplate in a proximal direction.

  • Publication number: 20240238555
    Abstract: A guide extension catheter positionable within a guide catheter and configured to receive an interventional device for insertion into vasculature is disclosed. The guide extension catheter can comprise a push member, a first reinforcement member in contact with the push member, and a radially-collapsible, tubular membrane in contact with the push member and the first reinforcement member. The tubular membrane can be positioned distal to the first reinforcement member and radially collapsed or wrapped about the push member prior to receiving the interventional device. The push member can provide column strength sufficient to prevent longitudinal collapse of the tubular membrane during use. The guide extension catheter can provide a low friction, large diameter (for a given compatible guide catheter size) pathway proximal to, and optionally through, a target lesion in the vasculature, thereby reducing micro and macro vasculature injury attributable to delivery of interventional devices.

  • Patent number: 11752307
    Abstract: This patent document discloses accessory devices and associated methods for catheter and guidewire management in a surgical setting. Implementations can include an accessory device having a manually deformable body that includes proximal and distal surfaces. The body may further define at least first and second apertures, each aperture extending through the body. The first aperture can be engageable with a proximal end portion of a first elongate medical device, and the second aperture can be configured to receive a second elongate medical device. The body can be slidable along the proximal end portion of the first elongate medical device and/or the second elongate medical device, and the proximal surface of the body may include a funnel leading into the first aperture, the second aperture, or both. The body may be incorporated into, or attached to, a proximal side of a hemostasis valve utilized for a medical operation.

  • Publication number: 20230270990
    Abstract: This patent document discloses devices and associated methods for catheter and guidewire management in a surgical setting. Implementations can include a hemostasis valve configured to prevent the backflow of blood during a medical procedure. The hemostasis valve can have a valve body defining an inner lumen extending from a proximal end of the body to a distal end of the body. The inner lumen can be configured to accommodate passage of one or more elongate interventional devices therethrough. An interventional device management component can be positioned at the proximal end of the valve body. The interventional device management component can comprise a body defining a first seal member lumen configured to receive a first elongate interventional device and a second seal member lumen configured to receive a second elongate interventional device. A narrow slit configured to receive a guidewire can connect the seal member lumens.

  • Patent number: 11524142
    Abstract: Guide extension catheters and related methods are disclosed. A guide extension catheter can comprise an elongate tube member, a push member, and an external manipulation member. The push member can be eccentrically coupled relative to the tube member and extend proximally therefrom for slidably positioning the tube member within and partially beyond a distal end of a guide catheter. The manipulation member can be coupled to a proximal end of the push member, where the manipulation member can be configured to secure the guide extension catheter in place during use by attaching to an external object such that the tube member and push member remain stationary without user engagement.

  • Publication number: 20220257910
    Abstract: Split support catheters, loading tools, and methods of use are disclosed. A support catheter can include an elongate tubular member and a push member. The tubular member can comprise a longitudinal slit configured to accommodate the exchange of various interventional devices into and out of the lumen defined by the tubular member. A loading tool can comprise a body member, a rod member, or both and can facilitate loading of the support catheter onto one or more interventional devices during a medical procedure. The support catheters can provide intravascular support to various interventional devices and can advantageously be inserted and removed without first removing an interventional device having its distal end at or near a target site within a patient's vasculature.

  • Publication number: 20220151622
    Abstract: Wire assemblies and methods for blood vessel occlusion in vascular procedures. The wire assemblies comprise a shaft and an occlusion member. The shaft includes a proximal end portion, a distal end portion spaced from the proximal end portion, a lumen, and a cross-sectional dimension that is perpendicular to the longitudinal axis. The occlusion member is configured to transition between a collapsed configuration and an expanded configuration.

  • Publication number: 20210196928
    Abstract: Percutaneous devices and methods for releasably engaging a guidewire against an inner surface of a tubular member are disclosed. A percutaneous device can include a tube member, a push member, and a fixation mechanism such as a fixation balloon. The tube member can define a lumen sized and shaped to receive one or more interventional medical devices therethrough and can have an outer diameter smaller than a lumen of a guide catheter. The push member can extend proximal of the tube member for slidably positioning a distal end portion of the tube member within and beyond a distal end of the guide catheter. The push member can include a lumen in fluid communication with an interior of the fixation balloon, for example, for delivering inflation fluid to, or removing fluid from, the balloon. The fixation balloon can be positioned can be positioned and configured to engage a guidewire against the inner surface of the guide catheter or of the tube member when inflated.
