Problems solved by technology

Also, the overall flexibility of the system is reduced due to the inflation lumen and bilayer construction required to inflate the distal balloon
The combination of large overall profile and lack of distal flexibility makes it difficult to track these devices in neurovascular anatomy

Embodiment Construction

[0023] Referring now to the drawings, wherein like reference numerals indicate like parts, various embodiments of balloon assist devices and methods of use thereof will be disclosed in detail. figure 1 is a schematic diagram of balloon assist device 100 showing the basic components. Balloon assist device 100 includes balloon assembly 200 , inflation tube 104 and inflation port 106 . figure 2 is a close up view of balloon assembly 200 . Balloon assembly 200 includes a balloon 202 secured to an inner body 204 . In an alternative example, inner body 204 may be integrally formed with balloon 202 . The inner body extends along axis 208 from proximal end 210 to distal end 212 and includes slit 206 for mounting balloon assist device 100 to a catheter. Thus, the inner body 204 partially surrounds the axis 208 . image 3 and Figure 4 One embodiment in which the balloon 202 is attached to the inner body 204 is shown. In this embodiment, the balloon 202 includes a sheath 214 of f...

Abstract

The invention relates to a split balloon assist device and a method of mounting it. A balloon assist device (100) is disclosed which includes an inner body (204) and a balloon (202) bonded to the inner body. The inner body extends along an axis (208) from a proximal end to a distal end and the cross-section of the inner body partially encloses the axis. The balloon assist device also includes an inflation tube (104) in sealed communication with the volume enclosed by the inner body and the sheath. The balloon assist device may also include a pusher for sliding the balloon assist device along the catheter. The pusher may extend parallel to the axis from the proximal end of the balloon assist device in a proximal direction. The inflation tube may also be used as a pusher. The inner body of the balloon assist device is a split cylinder extending along the axis from the proximal end to the distal end.

Description

technical field [0001] The present disclosure relates generally to the field of tools for vascular surgery. More specifically, the present invention relates to balloon devices for occluding blood vessels during vascular surgery. Background technique [0002] Balloon-guided catheters facilitate insertion of intravascular devices and control / restriction of flow in ischemic applications. They are designed with a large lumen to maximize clot capture and are indicated for catheters used as clot retrieval devices. Because the balloon is an integral part of the assembly on these devices, the devices have a very large profile, eg, 8F, compared to conventional large ID guide catheters, which may measure 6F (2.0mm) (French "F" = 0.33mm) (2.7mm). Also, the overall flexibility of the system is reduced due to the inflation lumen and bi-layer construction required to inflate the distal balloon. The combination of large overall profile and lack of distal flexibility makes tracking thes...
