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.

Guidewire fixation

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.

Guidewire and catheter management device and related methods

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.
