Abstract
Abstract A sterilized medical appliance is disclosed, consisting of a preassembled catheter or endotracheal tube with connector, guide, stop, and handle, packaged within a sealed envelope and ready for immediate use in case of emergency. The assembled and packaged appliance is gas-sterilizable within the sealed envelope. The guide positioned within the endotracheal tube serves to provide structural support and protection for the endotracheal tube during handling and shipping. The endotracheal tube surrounding the guide serves to reduce the risk of penetration of the sealed envelope by the distal tip portion of the guide. The envelope is composed of a tough, flexible, transparent, plastic material to permit visual inspection and to enable the manual configuration of the endotracheal tube, with guide inserted, into a desired shape for intubation without danger of rupture of the envelope and without loss of sterility.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
424 words
A packaged medical appliance comprising in combination: (a) an elongated, cylindrical catheter consisting of a flexible hollow tube having open distal and proximal ends; (b) a hollow connector having a cylindrical spout section of small diameter at one end and a cyindrical open end section of larger diameter at the other end, the cylindrical spout section being inserted into the open proximal end of said catheter; (c) a long catheter guide consisting of a wire of malleable material having rounded distal and proximal ends, a portion of the length of said catheter guide being situated within said hollow, cylindrical catheter, with the distal end of said catheter guide being positioned near the open distal end of said catheter; (d) a stop means affixed to said catheter guide, said stop means being supported by the cylindrical open end section of said hollow connector, said stop means being positioned along said guide to predetermine the length of the portion of said guide situated within said catheter at less than the length of said catheter and inserted connector to prevent the distal end of said guide from extending beyond the open distal end of said catheter, the portion of the length of said catheter guide situated outside said hollow cylindrical catheter and said hollow connector being formed into a shape for use as a handle, said handle having a smooth, rounded end; and (e) a flexible envelope of tough gas-permeable material completely enclosing and sealing said catheter, connector, guide and stop means; said catheter with connector, guide and stop means being gas-sterilizable within said gas-permeable envelope, the flexible distal end of said hollow catheter providing protection against rupture of said flexible envelope by the distal end of said catheter guide, said catheter guide providing structural support and protection for said hollow, flexible catheter during shipment, and said catheter and the portion of the length of said guide situated within said catheter being manually configurable into a desired shape for intubation while enclosed within said flexible envelope, the configuration being achieved without rupture of said envelope and without loss of sterility of said catheter, connector, guide and stop means, said flexible envelope having a peelable flap portion located at one end thereof adjacent the smooth, rounded end of said handle, the smooth, rounded end of said handle minimizing the risk of rupture of said flexible envelope during handling and shipment, said catheter with inserted connector, guide and stop means being ready for immediate use upon removal from said envelope by peeling away said flap thereby rupturing the seal.
Claim 2
Dependent Claim
424 words
A packaged medical appliance comprising in combination: (a) an elongated, cylindrical catheter consisting of a flexible hollow tube having open distal and proximal ends; (b) a hollow connector having a cylindrical spout section of small diameter at one end and a cyindrical open end section of larger diameter at the other end, the cylindrical spout section being inserted into the open proximal end of said catheter; (c) a long catheter guide consisting of a wire of malleable material having rounded distal and proximal ends, a portion of the length of said catheter guide being situated within said hollow, cylindrical catheter, with the distal end of said catheter guide being positioned near the open distal end of said catheter; (d) a stop means affixed to said catheter guide, said stop means being supported by the cylindrical open end section of said hollow connector, said stop means being positioned along said guide to predetermine the length of the portion of said guide situated within said catheter at less than the length of said catheter and inserted connector to prevent the distal end of said guide from extending beyond the open distal end of said catheter, the portion of the length of said catheter guide situated outside said hollow cylindrical catheter and said hollow connector being formed into a shape for use as a handle, said handle having a smooth, rounded end; and (e) a flexible envelope of tough gas-permeable material completely enclosing and sealing said catheter, connector, guide and stop means; said catheter with connector, guide and stop means being gas-sterilizable within said gas-permeable envelope, the flexible distal end of said hollow catheter providing protection against rupture of said flexible envelope by the distal end of said catheter guide, said catheter guide providing structural support and protection for said hollow, flexible catheter during shipment, and said catheter and the portion of the length of said guide situated within said catheter being manually configurable into a desired shape for intubation while enclosed within said flexible envelope, the configuration being achieved without rupture of said envelope and without loss of sterility of said catheter, connector, guide and stop means, said flexible envelope having a peelable flap portion located at one end thereof adjacent the smooth, rounded end of said handle, the smooth, rounded end of said handle minimizing the risk of rupture of said flexible envelope during handling and shipment, said catheter with inserted connector, guide and stop means being ready for immediate use upon removal from said envelope by peeling away said flap thereby rupturing the seal.
