Abstract

A storage unit for use in storing a prosthetic heart valve in conjunction with a plurality of heart valve orifice measurement gauges that includes separate container units (11 and 12), which container units can be selectively connected and disconnected by a connecting unit (13). Opening units (14) are provided for each container unit (11 and 12) to allow access to secondary container units (16) contained therein. The secondary container units contain separately the prosthetic heart valve and heart valve orifice measurement gauges under sterile conditions. Object indicia (18) are provided on the container units (11 and 12) to indicate the contents and size of the heart valve stored within the storage unit. Substantially opaque package unit envelops the first and second container units (11 and 12), though a window unit (21) is provided to allow visual observation of the object indicia (18).

Claims

1. A storage unit for use in storing a prosthetic heart valve and a plurality of heart valve opening measurement gauges prior to use thereof, comprising:

(a) first and second container units;

(b) connecting means for selectively connecting and disconnecting said first and second container units to and from one another;

(c) first opening means for selectively gaining access to said first container unit but not to said second container unit;

(d) second opening means for selectively gaining access to said second container unit but not to said first container unit; and

(e) object indicia visibly disposed on either of said first and second container units to identify the size and type of said prosthetic heart valve stored within said storage unit.

2. The storage unit of claim 1 wherein:

(a) said first container unit has a first secondary container unit disposed therein; and

(b) said second container unit has a second secondary container unit disposed therein.

3. The storage unit of claim 2 wherein:

(a) said first secondary container unit contains said prosthetic heart valve; and

(b) said second secondary container unit contains said plurality of heart valve opening measurement gauges.

4. The storage unit of claim 3 wherein said first and second container units and said first and second secondary container units are each individually hermetically sealed.

5. The storage unit of claim 1 wherein said connecting means includes:

(a) a plurality of locking tabs disposed on said first container unit; and

(b) a plurality of tab receiving notches formed within said second container unit;

such that at least some of said tabs may be placed within at least some of said notches, said first and second container units being selectively rotatable with respect to one another to cause said tabs to become selectively locked and unlocked with respect to each other.

6. The storage unit of claim 5 wherein said first and second container units have a substantially similar configuration with respect to one another.

7. The storage unit of claim 1 and further including:

(a) a substantially opaque package means for substantially surrounding said first and second container units; and

(b) window means for rendering said object indicia viewable from outside said package means at all times when said first and second container units are disposed within said package means.

8. The storage unit of claim 7 wherein said substantially opaque package means includes two substantially equal halves that may be selectively abutted against one another.

9. The storage unit of claim 8 wherein said window means includes;

(a) a first cavity formed in one said half of said opaque package means; and

(b) a second cavity formed in said remaining one half of said opaque means;

such that when said two substantially equal halves are placed in abuttment, said first and second cavities combine to produce a single window.

10. The storage unit of claim 7 and further including sleeve means for at least partially enveloping said package means, without occluding said window means.
