Assignee:

R4 VASCULAR, INC. - Maple Grove MN

International Classification:

A61M 29/02

US Classification:

606194, 606191

Abstract:

The present invention provides a compliant balloon for use with a catheter having an inner compliant inner layer defining a cylindrical lumen encased by a fiber layer including non-braided inelastic fibers imparting integrity to the balloon wall. The balloon further includes radiopaque material which may be disposed over substantially the entire length of the balloon as a coating or by incorporation within the fiber layer or an outer coating layer. The balloon is expandable from a folded deflated state to an inflated state by increasing pressure within the balloon and can be used with saline as the sole inflation medium to allow rapid deflation as compared to use of a balloon with a contrast medium.

International Classification:

A61B 17/22
A61M 25/10

Abstract:

A medical device may include an elongated body, a balloon positioned at a distal portion of the elongated body, and one or more pressure-wave emitters positioned along a central longitudinal axis of the elongated body within the balloon. The one or more pressure-wave emitters may be configured to propagate pressure waves radially outward through the fluid to fragment a calcified lesion at the target treatment site. The at least one of the one or more pressure-wave emitters may include an electronic emitter comprising a first electrode and a second electrode. The first electrode and the second electrode may be arranged to define a spark gap between the first electrode and the second electrode, and the second electrode may comprise a portion of a hypotube.

Abstract:

The disclosure includes a vein ablation system, comprising a catheter having an elongated body. In some embodiments, the vein ablation system comprises an ablation device at a distal portion of the elongated body. According to some embodiments, the vein ablation system comprises a control device at a proximal portion of the elongated body. The control device may comprise an input mechanism configured to simultaneously control at least two of a longitudinal translation of the ablation device through a target vessel, a rotation of the ablation device about a central longitudinal axis, and an infusion of a chemical agent into the target vessel.

International Classification:

A61B 17/22

Abstract:

A balloon guiding sheath may include an elongated sheath comprising a proximal end, a distal end, an inner tube, an outer tube surrounding the inner tube, an access port, a distal port, and a working lumen extending through an interior portion of the elongated sheath between the access port and the distal port. The balloon guiding sheath may also include an inflatable balloon located on an outer surface of the elongated sheath adjacent the distal end. The balloon guiding sheath may include a plurality of inflation holes extending through a side wall of the elongated sheath. The elongated sheath may be sized and configured to enable direct insertion into a patient's vasculature through an arteriotomy in at least one of a femoral artery and vertebral artery to position the inflatable balloon at a target site.

International Classification:

A61F 2/24

Abstract:

An anchor assembly is configured to implant a cardiac anchor into a heart wall of a patient to anchor a suture configured to extend from a valve leaflet of the heart as an artificial chordae. The anchor assembly can include an anchor hub defining an open interior and a helical coil extending distally from the anchor hub and having a sharpened tip configured to embed the helical coil into the heart wall upon rotation of the helical coil. A spring can be disposed within the open interior of the anchor hub. Compressing the spring distally can create an open space within the open interior of the anchor hub for a suture extending through the anchor hub to slide freely and releasing compression on the spring can cause the spring to expand in a proximal direction to clamp the suture within the open interior of the anchor hub.
