Abstract
An intubation set includes a flexible sheath, a probe inserted in the flexible sheath having a proximal end extending out of the sheath and a length of tubing secured to the sheath to permit the tubing to be positioned in a body by inserting the probe within the sheath into the body, withdrawing the probe from the sheath and pulling the sheath through the body to position the tubing by grasping an end of the sheath. A method of positioning the length of tubing in the lacrimal ducts utilizes the intubation set with a pair of flexible sheaths connected with the tubing and a pair of probes received in the sheaths.
Claims10
An intubation set for use in reconstruction of the lacrimal ducts comprising
- tubing means including a pair of flexible sheath portions each having a closed end and a side wall with an opening therein and a tubing portion connecting said sheath portions;
- and
- a pair of probes each slidably received in one of said sheath portions and having a distal end disposed at said closed end thereof and a proximal end extending through said opening whereby said tubing portion can be positioned in the lacrimal ducts by inserting said probes within said sheath portions into the lacrimal drainage ducts, withdrawing said probes from said sheath portions and pulling said sheath portions through the lacrimal ducts by grasping said closed end.
A method of positioning a flexible elongate member in the lacrimal ducts comprising the steps of
- passing a pair of probes through the puncti lacrimalia, the canaliculi, the lacrimal sac, the nasolacrimal ducts and into the nose, the probes each being inserted in a flexible tubular sheath and the tubular sheaths being connected with the elongate member;
- withdrawing the probes from the tubular sheaths;
- grasping the ends of the tubular sheaths through the nose;
- pulling the tubular sheaths through the nose to position the elongate member in the lacrimal ducts;
- and
- separating the elongate member from the tubular sheaths.
