Benefits of technology

"The invention is about a catheter with a rapid exchange segment that can be used to deliver medical devices into blood vessels. The rapid exchange segment is a tubular element with a slit structure that allows it to track over a cylindrical object and support the placement of the medical device. The catheter can also be used to deliver a guidewire into a vessel. The technical effects of this invention include improved placement of medical devices and easier delivery of guidewires."

Problems solved by technology

One common complication of percutaneous procedures is the inability to gain access to a vessel and thus to properly position the interventional devices past the target position.
Additional factors, such as poor guide support, can further lead to crossing issues.

Embodiment Construction

[0040] A deflection and support catheter as described herein provides assistance to direct an elongate member within a blood vessel during a percutaneous procedure into a difficult to reach branch vessel. The deflection and support catheter can provide both direction and support for entering into a difficult branch vessel to navigate. In some embodiments, the deflection and support catheter has a side port at a stiffened section to provide support while the elongate member is directed through the side port into a difficult to reach vessel. In appropriate embodiments, once the side port is properly positioned, the curved tip of the elongate member, such as a guidewire, facilitates the entry of the elongate member out from the side port into the difficult to reach vessel. With the support from a deflection and support catheter, the physician can manipulate a guidewire past difficult to reach positions in the branch vessel, such as past thrombus accumulated at or near the vessel openin...

Abstract

A deflection and support catheter provided for improved manipulation of elongated medical devices used during percutaneous procedures in difficult to reach situations. In particular, the deflection and support catheters can facilitate placement of guidewires, guide catheters, and intervention devices such as angioplasty balloons and stent delivery devices.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to copending provisional patent application Ser. No. 60 / 762,304 filed on Jan. 26, 2006 to Webster et al., entitled “Deflection Control Catheter and Related Method of Use,” incorporated herein by reference.FIELD OF THE INVENTION [0002] The invention relates to catheters to facilitate the delivery of guidewires, guide catheters or other interventional devices within a branched vascular network. The invention further relates to methods for the delivery of guidewires, guide catheters or other interventional devices along branched vessels in a body. BACKGROUND OF THE INVENTION [0003] Percutaneous vascular procedures are performed in many vessels in the body, including, for example, the coronary arteries, saphenous vein grafts, carotid arteries, cerebral vessels, and peripheral vessels. These procedures generally require the physician to gain access to the target vessel with a guiding catheter or sheath and tr...
