Abstract
Disclosed is an assembly of parts for an endourological procedure, including a tubular sheath and an introducer, the tubular sheath being removably mounted on the introducer. The introducer comprises a security channel that is openable to shift a guidewire from a position inside the security channel to a position outside and next to the tubular sheath. Disclosed are also access sheaths and a method of performing an endourological procedure.
Claims10
An assembly of parts for an endourological procedure comprising an introducer and a tubular sheath removably engaged on the introducer,
- the tubular sheath comprising a lumen extending between a proximal end and a distal end of the tubular sheath,
- the introducer comprising a security channel along at least a part of a longitudinal extent defined between a tapered proximal end and a distal end, the security channel adapted to configure the introducer to accommodate a single guidewire during insertion of the assembly into the body of a patient,
- the security channel extending between a proximal hole and a distal hole of the introducer, a wall section of the introducer extending between the proximal and distal holes of the security channel arranged to open under the action of a radially outwardly directed force, wherein
- the security channel comprises an ejector operable to eject the single guidewire out of the security channel and out of the introducer.
A method of accessing a ureter, the method comprising:
- inserting a single guidewire through the natural urinary canal and into the ureter;
- passing an introducer inserted into a tubular sheath along the single guidewire by inserting the single guidewire into and along an openable security channel of the introducer;
- pushing the single guidewire out of the security channel by a radially outwardly directed force provided by an ejector comprised in the security channel, and
- retracting the introducer from the tubular sheath leaving the single guidewire outside and next to the tubular sheath to function as a security wire.
