Abstract
A detachable balloon catheter comprising a sealing valve assembly having an elongated passageway extending therethrough, an inflatable balloon having a mouth portion which is bonded to the periphery of the sealing valve assembly, and a small diameter cannula having a distal end which extends through the passageway in the sealing valve assembly. The small diameter cannula includes a connector terminal on the proximal end which is adapted to be coupled to a source of fluid pressure. The sealing valve assembly includes a valve mechanism which permits the passage of the cannula through the passageway but prevents the flow of fluid through the passageway when the cannula is removed. The balloon catheter also includes a cannula retainer mechanism which is formed of a resilient material and has an annular cavity for frictionally engaging the outer surface of the distal end of the cannula so that a predetermined force is required to withdraw the cannula from the retainer mechanism. The retainer mechanism is affixed to the inside surface of the balloon at a position diametrically opposite to the mouth of the balloon so that when the balloon is inflated to a desired size, the cannula is withdrawn from the retainer mechanism to thereby cause the balloon to become detached from the cannula.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
