Description
~BSB~2 BACKGROUND OF THE INVENTION
The present invention relates to kennels.
It is a common procedure to spray the laryngotracheal area with a topical anesthetic prior to endotrac~eal incubation, but the present catheters to accomplish this result are doff-client. It is desirable for such catheters to have a soft tip to prevent perforating the trachea and damage to the vocal cords during use. It is also desirable for the catheters to have a curve in the catheters to fit the trachea. However, if the catheters are made from a soft material to provide the soft tip, the catheters are too flexible and do not maintain the desired curve.
SUMMARY OF _ E IN MENTION
A principal feature of the present invention is the provision of an improved Connally.
The Connally of the present invention comprises, an elonyatecl catheter having a wall defining a lumen, and opening means in a distal portion of the catheter communicating with the lumen, and an elongated malleable insert in the wall of the I catheter.
A feature of the present invention is that the tip of a syringe may be attached to the proximal end of the catheter in order to pump a topical anesthetic into the lumen.
Another feature of the invention is that the Connally sprays the topical anesthetic through the catheter opening means onto the larynyotracheal area.
A further feature of the invention is that the cache-ton may be made of a relatively soft material to provide a tip which is relatively soft to prevent perforating the trachea and damage to the vocal cords during use of the Connally.
Sue Yet another feature of the invention is that the oath-ever may be curved, and the insert maintains this shape to impart a curve to the Connally in order to fit the trachea.
Thus, a feature of the present invention is that the Connally has a relatively soft tip in spite that it may be curved.
Further features will become more fully apparent in the following description of the embodiments of this invention and from the appended claims.

DESCRIPTION OF TIE PREFERRED EMBODIMENTS
Referring now to Figs. l and 2, there is shown a can-null generally designated 10 comprising an elongated catheter 12 having an elongated malleable insert 14 in a wall 16 of the I catheter 12. The catheter 12 has a proximal end 18, a distal end 20, a lumen 22 extending substantially the length of the catheter 12, and a plurality of openings 24 extending through the wall 16 in a distal end portion 26 of the catheter 12 and so communicating with the lumen 22. The catheter is preferably made from a relatively soft material, such as silicone rubber, to provide a relatively soft tip 28 at the distal end 20 of the catheter 12.
In the present form, the insert I comprises an eon-grated rod 30 of malleable material, such as stainless steel As shown, the rod 30 extends a substantial length of the catheter 12, and has a distal end 32 spaced a substantial distance from the distal end 20 of the catheter 12.
1.0 In accordance with the present invention, the catheter 12 may be bent to a desired shape to fit the trachea, and the insert 14 maintains the catheter in the desired shape. As pro-piously discussed, the catheter is made from a relatively soft material in order to provide a relatively soft tip 28 for the catheter 12, with the insert 14 being spaced from the tip 28 to maintain softness of the tip 28. Thus, the catheter 12 has a relatively soft tip to prevent perforating the trachea and dam-aye to the vocal cords during use, yet the catheter may have a curve to fit the trachea of a patient. After placement of the catheter ion the trachea, the tip of a syringe (not shown) is attached to the proximal end 18 of the catheter 12. The syringe is then pumped to eject a topical anesthetic in-to the lumen 22 and through the openings 24 onto the laryngotracheal area of the patient prior to endotracheal incubation.
Another embodiment of the present invention is thus-treated in Fig. 3, in which like reference numerals designate like parts. In this embodiment, the catheter 12 has a plurality ox malleable inserts 14, comprising a first rod 30 and a second rod 34 on opposed sides of the catheter. The catheter 12 of on ivy 3 operates in a manner as previously described in connection Wyeth -the catheter of Figs. 1 and 2.
~3S86;~
Another embodiment of the present invention is thus-treated in Fig. 4, in which like reference numerals designate like parts. In this embodiment, the catheter 12 has a pair of malleable inserts 14 comprising a pair of rods 30 and 34 which are closely spaced from each other. The catheter 12 of Fig. 4 operates in a manner as previously described in connection with the catheter of Figs. 1 and 2.
Another embodiment of the present invention is thus-treated in Fig. 5, in which like reference numerals designate like parts. In this embodiment, the catheter 12 has a generally cylindrical malleable member 36 embedded in the wall 16 of the catheter 12. The cylindrical member 36 may have a plurality of openings 33 extending through the member 36 to permit attachment of the inner and outer portions of the catheter wall 16 together through the member 36. The catheter 12 of Fix. 5 operates in a manner as previously described in connection with the catheter of FicJs. 1 and 2.
The foregoing detailed description is given for clear-news ox understanding only, and no unnecessary limitations should be understood therefrom, as modifications will be obvious to -kiwi swilled in the art.
