20080221614 | Method for Closing an Arteriotomy - A method for closing an arteriotomy includes providing a guiding system and a closure system. The guiding system advanced through a sheath extending through the arteriotomy and into the blood vessel lumen. The guiding system includes a pair of stabilization wire guides, each guide including a retention foot disposed at a distal portion thereof. The retention feet are deployed within the lumen. With the entire sheath outside of the vessel, the closure device is then further advanced along the guiding system, or the sheath is pulled proximally over the closure device, thereby stretching or tearing a distal portion of the sheath. The closure system includes a closure device, such as a stapler including a staple that is actuated to close the arteriotomy. The retention feet are undeployed and the guiding system is removed from the body. | 09-11-2008 |
20080262541 | BLOOD VESSEL CLOSURE - A stapling arrangement and method for closing a percutaneously formed arteriotomy includes a plurality of staple prongs commonly connected at their proximal ends and having distal ends adapted to engage tissue on opposite sides of the arteriotomy. The prongs have an arrangement of stops configured to present different degrees of resistance to advancement through tissue. | 10-23-2008 |
20080269794 | LOW PROFILE DILATOR FOR ARTERIOTOMY CLOSURE SYSTEM - 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. | 10-30-2008 |
20080269800 | ARTERIOTOMY CLOSURE SYSTEM WITH DUAL LUMENS SHEATH - An arteriotomy closure system includes a double barrel sheath having parallel dedicated lumens that merge at a distal juncture into a single common lumen. One of the dedicated lumens receives a dilator and the other a stapler. One of the dilator or stapler can be advanced from its dedicated lumen distally through the common lumen and beyond the distal end of the sheath while the other of the dilator or stapler is retracted into its dedicated lumen. | 10-30-2008 |
20090082802 | Mechanism and Method for Closing an Arteriotomy - Devices and methods for closing an arteriotomy by gripping surfaces of tissue disposed about the arteriotomy, without piercing the tissue, and drawing the gripped tissue together to approximate the edges of the arteriotomy, and, while holding the tissue, applying a more permanent closure to the tissue. | 03-26-2009 |
20090264922 | Device and Method for Effecting Hemostasis about a Blood Vessel Puncture - A device and method for closing a percutaneous vascular puncture with anchors at the distal ends of wires temporarily implanted in extravascular tissue adjacent the puncture. The wires are tensioned to draw the tissue together to approximate the edges of the puncture. The wires are retained in that position while the blood in the region of the arteriotomy clots. When hemostasis has been achieved, the anchoring wires then can be removed. | 10-22-2009 |
20090270807 | Aspiration Catheter Having An Internal Vacuum Accumulator - An aspiration catheter is provided in which vacuum may be accumulated within the catheter and released suddenly within a distal region of the catheter to induce ingestion of intravascular matter into the catheter through an open distal port while avoiding large losses of suction common with catheters having long aspiration lumens. Conventional aspiration using the same catheter can subsequently complement the procedure by fully removing the ingested matter from the catheter. | 10-29-2009 |
20090270808 | Aspiration Catheter Having Variable Volume Distal Suction Chamber - An aspiration catheter is provided in which rapid withdrawal of a piston disposed within a distal region of a catheter lumen creates a sudden pressure drop for ingestion of intravascular matter into the catheter lumen through a distal port while avoiding large losses of suction common with catheters having long aspiration lumens. Conventional aspiration using the same catheter can subsequently complement the procedure by fully removing the ingested matter from the catheter. | 10-29-2009 |
