A method for constructing a braided implant delivery system and treating an aneurysm can include attaching a braided implant having a band attached thereto to a delivery tube, positioning the braided implant within the aneurysm, and releasing the band from the delivery tube, thereby releasing the braided implant. The band can include movable extensions that can press into an outer surface of the delivery tube to secure the band to the delivery tube then move away from the outer surface of the delivery tube to release the band. A pull wire can be engaged to the band to secure the band to the delivery tube then be pulled proximally to release the band from the delivery tube. At least a portion of the braid of the braided implant can be positioned within a lumen of the delivery tube.

20230045964 · 2023-02-16 ·

An interventional catheter for treating an artery includes an elongated body sized and shaped to be transcervically introduced into a common carotid artery at an access location in the neck. The elongated body has an overall length such that the distal most section can be positioned in an intracranial artery and at least a portion of the proximal most section is positioned in the common carotid artery during use.

MULTI-LUMEN CATHETERS

A delivery device may comprise a sheath configured to be inserted into a body lumen of a patient. The sheath may have a proximal end, a distal end, a first channel extending within the sheath from the proximal end to the distal end, and a second channel extending within the sheath from the proximal end to the distal end. A collective cross-sectional area of the first channel and the second channel may be more than 50% of a total cross sectional area of the sheath. The device may also be comprised of a handle at the proximal end of the sheath, wherein the handle is configured to provide fluid communication between a first port and the first channel and a second port and the second channel.
