Benefits of technology

[0022] It should be noted that in some variations of the invention, all or some of the filaments (used in the surrounding portion of the device) can be designed to increase their ability to adhere to the obstruction. For example, the filaments of the surrounding portion may be coupled to an energy source (e.g., RF, ultrasonic, or thermal energy) to “weld” to the obstruction. Application of energy to the filaments may allow the surrounding portion to deform into the obstruction and “embed” within the obstruction. Alternatively, th

Problems solved by technology

It should be noted that although minimal axial movement of the obstruction may take place, the device surrounds the obstruction before such movement causes

Embodiment Construction

[0041] It is understood that the examples below discuss uses in the cerebral vasculature (namely the arteries). However, unless specifically noted, variations of the device and method are not limited to use in the cerebral vasculature. Instead, the invention may have applicability in various parts of the body. Moreover, the invention may be used in various procedures where the benefits of the method and / or device are desired.

[0042]FIG. 1 illustrates a system 10 for removing obstructions from body lumens as described herein. In the illustrated example, this variation of the system 10 is suited for removal of an obstruction in the cerebral vasculature. Typically, the system 10 includes a catheter 12 microcatheter, sheath, guide-catheter, or simple tube / sheath configuration for delivery of the obstruction removal device to the target anatomy. The catheter should be sufficient to deliver the device as discussed below. The catheter 12 may optionally include an inflatable balloon 18 for ...

Abstract

The devices and methods described herein relate to clearing of blockages within body lumens, such as the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a non-provisional of U.S. Provisional Application No. 60 / 765,496 filed Feb. 03, 2006 which is incorporated by reference in its entirety.FIELD OF THE INVENTION [0002] The devices and methods described herein relate to clearing of blockages within body lumens, such as the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate the obstruction within the body lumen. In one variation, the devices and methods described below may treat conditions of ischemic stroke by remove blockages within arteries leading to the brain. Accordingly, variations of such methods and devices must navigate tortuous anatomy and vasculature without causing unacceptable damage to the anatomy. Also, the devices and methods first secure and surround the obstruction (such as a clot) prior to significantly moving the clot within the anatomy. BACKGROUND OF THE INVENTION [0003] Ischemic stroke occurs wh...
