US Patent:

20100234875, Sep 16, 2010

Filed:

Oct 30, 2009

Appl. No.:

12/610102

Inventors:

Steven J. Allex - Shoreview MN, US
Donald Geer - Plymouth MN, US
Brett Allyn Williams - Lino Lakes MN, US
Brady Jon Hatcher - Rogers MN, US
Tristan Lynn Tieso - Fridley MN, US

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:

A61F 2/84

US Classification:

623 111

Abstract:

The present disclosure concerns a delivery system for delivering a medically useful payload through the vasculature to a site of interest in the patient's body. The medically useful payload may be a therapeutic device, such as a stent, and it may be a diagnostic tool, such as an imaging device. Owing to its structural attributes, the presently-inventive delivery system is well suited for carrying medical payload to and through vessel curvature and to branched regions (i.e., bifurcations) in same. Also, the device is well-suited to traveling through a vessel over a guiding element, such as a guidewire, which itself exhibits curvature.

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.
