Abstract
A piercing device for use with an essentially rigid medical instrument having a proximal portion and a distal portion including working means for performing some medical procedure in an internal portion of the body of a living being. The piercing device comprises a guide member having a handle at the proximal end. The guide member comprises an elongated trough shaped, U-shaped, sidewall having an inner surface, and a distal end in the form of a piercing tip. The device is arranged to be held so that the piercing tip can be pierced through the skin and at least a portion of the underlying tissue to form a trough shaped percutaneous puncture. The tissue contiguous with the puncture engages the inner and outer surfaces of the sidewall to form a generally fluid tight interface therebetween. The working means of the instrument can be readily slid along the inner surface of the guide member after the device has formed the percutaneous puncture so that the working means passes through the trough shaped puncture into the being's body. The piercing device is then removed from the percutaneous puncture, leaving the instrument in place with the tissue contiguous with the puncture closely engaging peripheral portions of the instrument at a fluid tight interface so that substantially no fluid leaks out of the interface and so that the working means can be operated to perform the procedure.

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.
