A tear open package for a catheter having an insertion end and a funnel end includes a pair of thin elongated sheets of gas impermeable material joined about their edges by a perimeter heat seal. The elongated sheets of material form a catheter-receiving cavity in which the catheter insertion end is near one end of the cavity and the funnel end is near the other end of the cavity. The perimeter heat seal includes at least an insertion end heat seal, a funnel end heat seal, and a pair of side heat seals which extend along each side of the package from the insertion end heat seal to the funnel end heat seal. The elongated sheets of material each include a tear line extending at least from one side of the package toward the other side of the package through at least one of the side heat seals. The tear lines extend between the catheter insertion end and the insertion end heat seal for opening at least the insertion end of the package by controlled tearing for removal and use of the catheter.

The tear open package of claim 3 wherein the continuous chevron-shaped insertion end tear lines are located generally between the chevron-shaped heat seal portions and the insertion end heat seal portion. 5. The tear open package of claim 4 wherein the continuous chevron-shaped insertion end tear lines define a generally continuous curve at the point where they are closest to the insertion end heat seal portion. 6. A tear open package, for a hydrophilic catheter having an insertion end and a funnel end, comprising: a pair of thin elongated sheets of gas impermeable material joined about their edges by a perimeter heat seal, the elongated sheets of material defining an elongated cavity receiving a catheter therein, the catheter having the insertion end near one end of the cavity and the funnel end near the other end of the cavity; the perimeter heat seal including at least an insertion end heat seal portion at one end of the package, a funnel end heat seal portion at the other end of the package and first and second side heat seal portions along first and second sides of the package each extending from the insertion end heat seal portion to the funnel end heat seal portion in spaced relation to one another; an elongated interior heat seal extending from the insertion end heat seal portion to the funnel end heat seal portion in closely spaced parallel relation to one of the first and second side heat seal portions; a respective chevron-shaped insertion end heat seal portion angling inwardly from each of the first and second side heat seal portions toward the insertion end heat seal portion and terminating in spaced relation to the insertion end heat seal portion and to each other to define a narrow passageway therebetween; and a respective tear line in each of the elongated sheets of material extending in registration with one another from one side of the package toward the other between the insertion end of the catheter and the insertion end heat seal portion, the tear lines extending through the other of the first and second side heat seal portions and the elongated interior heat seal for opening the package adjacent the insertion end of the catheter by controlled tearing along the tear lines, the tear lines in the elongated sheets of material being formed into a first insertion end tear line portion and a second insertion end tear line portion to thereby define respective continuous chevron-shaped insertion end tear lines. 7. The tear open package of claim 6 wherein the continuous chevron-shaped insertion end tear lines are located generally between the chevron-shaped heat seal portions and the insertion end heat seal portion. 8. The tear open package of claim 7 wherein the continuous chevron-shaped insertion end tear lines define a generally continuous curve at the point where they are closest to the insertion end heat seal portion. 9. The tear open package of claim 7 including a side tear line in each of the elongated sheets of material extending from the continuous chevron-shaped insertion end tear lines toward the end heat seal portion. 10. The tear open package of claim 9 wherein the side tear lines extend between and parallel to the elongated interior heat seal and the one of the first and second side heat seal portions to near the end heat seal portion. 11. The tear open package of claim 9 including an end tear line in each of the elongated sheets of material extending from the side tear line inwardly of and generally parallel to the end heat seal portion. 12.

The tear open package of claim 12 wherein the continuous chevron-shaped insertion end tear lines, the side tear lines, and the end tear lines form a continuous tear line in each of the elongated sheets of material. 14. A tear open package, for a hydrophilic catheter having an insertion end and a funnel end, comprising: a pair of thin elongated sheets of gas impermeable material joined about their edges by a perimeter heat seal, the elongated sheets of material defining an elongated cavity receiving a catheter therein, the catheter having the insertion end near one end of the cavity and the funnel end near the other end of the cavity; the perimeter heat seal including at least an insertion end heat seal portion at one end of the package, a funnel end heat seal portion at the other end of the package and first and second side heat seal portions along first and second sides of the package each extending from the insertion end heat seal portion to the funnel end heat seal portion in spaced relation to one another; an elongated interior heat seal extending from the insertion end heat seal portion to the funnel end heat seal portion in closely spaced parallel relation to one of the first and second side heat seal portions; a respective chevron-shaped heat seal portion angling inwardly from each of the first and second side heat seal portions toward the insertion end heat seal portion and terminating in spaced relation to the insertion end heat seal portion and to each other to define a narrow passageway therebetween; and a respective continuous tear line in each of the elongated sheets of material in registration with one another and extending from a cutout in one side of the package toward the other side of the package between the insertion end of the catheter and the insertion end heat seal portion, and then extending generally parallel to and closely spaced from the other side of the package, and then extending back to the one side of the package between the funnel end of the catheter and the funnel end heat seal portion to an end point to open the cavity for the catheter adjacent both the insertion end and the funnel end while still covering the catheter; the portions of the continuous tear lines extending generally parallel to and closely spaced from the other side of the package being disposed between the elongated interior heat seal portion and the one of the first and second side heat seal portions; whereby the package is opened starting at the cutout in the one side of the package and continuing to the end point in the one side of the package by controlled tearing along the tear lines. 15. The tear open package of claim 14 wherein the portions of the continuous tear lines near the insertion end heat seal portion are continuous chevron-shaped tear lines, the chevron-shaped tear lines being located generally between the chevron-shaped heat seal portions and the insertion end heat seal portion, the chevron-shaped tear lines being curved at the point nearest the insertion end heat seal portion. 16. The tear open package of claim 15 wherein the chevron-shaped tear lines form chevron-shaped foldable flaps, the insertion end of the catheter extending through the narrow passageway defined by the chevron-shaped heat seal portions, the chevron-shaped flaps being foldable back past the insertion end of the catheter to the narrow passageway to expose the insertion end thereof. 17.
