A system and method for closing a percutaneous vessel puncture at the conclusion of a vascular catheterization procedure includes placement of an intravascular closure device having a radially and axially expandable tubular membrane and a radially expandable anchor at the distal end of the membrane. The closure device is placed, by a delivery catheter extending through the puncture site, with its anchor radially expanded in a location upstream of the puncture site to enable the force of a patient's blood flow to deploy the tubular membrane to a proximally extended configuration closing the puncture from within the vessel.

Systems and methods for closing a percutaneous vascular puncture

A rapid exchange-type catheter for aspiration of embolic debris from a blood vessel includes an elongate aspiration tube and a relatively short guidewire tube mounted beside a distalmost portion of the aspiration tube. A proximal portion of the guidewire tube defines a strain relief segment. In one embodiment, the strain relief segment is formed detached from the aspiration tube. In another embodiment, the strain relief segment is minimally attached to the aspiration tube and becomes detached from the aspiration tube when a sufficient transverse force is applied to urge the guidewire tube away from the aspiration tube.

Rapid exchange catheter with tear resistant guidewire shaft

An apparatus for placing a patch over a puncture wound in a blood vessel exteriorly of the vessel includes a device for delivering the patch in a folded form and then expanding the patch from its unfolded configuration while deploying the patch about the region of the vessel puncture.

Vascular puncture closure

An aspiration catheter includes an elastically deformable distal tip transformable between an orthogonal configuration and an oblique configuration to selectively and controllably appose the tip with thrombus or other matter to be aspirated. A core wire is slidably disposed in a core wire lumen within the catheter and is operably connected to the catheter distal tip. The core wire is controlled from the catheter proximal end to transform the distal tip between orthogonal and oblique configurations.

Aspiration catheter having selectively deformable tip

A closure device for an arteriotomy includes an elongate hollow shaft and an elongate driver slidably disposed therein. The elongate hollow shaft includes a pair of a pair of opposing actuation tips disposed at a distal end thereof defining a staple chamber there between. An anvil extends into the staple chamber from one of the actuation tips. The closure device includes a release mechanism for spreading apart the pair of opposing actuation tips to provide a gap associated with the anvil, the gap dimensioned such that the staple may pass there through. A method of using the closure device is also disclosed.

Low-profile vascular closure systems and methods of using same

A low profile, two lumen dilator is provided for an arteriotomy closure system. The dilator includes a first lumen adapted to receive a guidewire and a second lumen having a proximal segment that defines a blood marking lumen and a distal segment that receives the distal ends of stabilizers in a common pocket. The blood marking lumen and pocket are arranged in tandem. The guidewire lumen may extend the full length of the dilator or may be shortened to provide rapid exchange capability.

Low profile dilator for arteriotomy closure system

A flexible elongate device having a distally mounted occluder for collecting particulate debris in a body lumen. The occluder containing a fixed amount of fluid is reversibly expandable by push-pull actuation from a contracted configuration to a deployed configuration wherein the occluder is expanded into sealing engagement with the wall of the body lumen. The occluder has a distal end axially secured to an elongate inner member and a proximal end attached to a distal end of an outer tubular member. The occluder has an impermeable occluder casing for containing the occluder fluid. The elongate inner member is slidable within the outer tubular member such that relative longitudinal movement between the elongate inner member and outer tubular member changes the length of the occluder and thus redistributes the occluder fluid within the occluder casing to transform the occluder between its contracted and deployed configurations.

Device with actuatable fluid-column occluder for prevention of embolization

A closure device for an arteriotomy includes an elongate tube having a distal opening, a staple disposed within the tube, and a frangible cap mounted across the distal opening to guard the staple tips against contact with the tissue track. The frangible cap is pierced, fractured or torn when the staple is advanced through the distal opening. A portion of the torn frangible cap may be implanted with the staple as a pledget. The staple may be carried within the elongate tube by a stapler comprising an elongate hollow shaft and an elongate driver slidably disposed therein. A pair of opposing actuation tips is disposed at a distal end of the hollow shaft to define an open-sided staple chamber there between. An anvil is fixedly disposed within the staple chamber, which holds at least a proximal portion of the staple.

A closure device for an arteriotomy includes an elongate tube having a distal opening. The elongate tube has least two opposing longitudinal slots and a pair of opposing corners defined where each slot meets the distal opening. A staple is disposed within the tube, the staple having at least two opposing legs aligned with the at least two slots. Each slot is pinched together adjacent the distal opening such that the opposing corners of each slot converge to cover the tip of the respective staple leg to guard the staple tips against contact with the tissue track. The corners of each slot are separable to permit the respective staple leg to pass there between.
