Abstract
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).

Claim 1
Independent Claim
121 words
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.
Claim 2
Dependent Claim
121 words
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.
Claim 3
Dependent Claim
34 words
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.
