Abstract
A volume indicator for a syringe can include an indicator body configured to removably clip onto a syringe body and a window portion extending through a thickness of the indicator body. The volume indicator can include inflation indicia corresponding to a range of expanded diameters for a prosthetic heart valve. The volume indicator can include one or more first engagement elements that correspond to one or more second engagement elements on a syringe.

A volume indicator for a syringe having a syringe body and a plunger received in the syringe body, the volume indicator comprising:
- an elongated indicator body having a first end portion and a second end portion and having a C-shape in cross section, the indicator body comprising an opening configured to receive the syringe body;
- a first engagement element disposed at the first end portion of the indicator body, the first engagement element extending from an inner surface of the indicator body into a thickness of the indicator body;
- a second engagement element disposed at an edge portion of the second end portion of the indicator body;
- and
- wherein the first and second engagement elements are configured to engage corresponding first and second engagement elements of the syringe body to restrain the indicator body from rotational and axial movement relative to the syringe body.
A volume indicator for a syringe having a syringe body and a plunger received in the syringe body, the volume indicator comprising:
- an elongated indicator body having a C-shape in cross section defining an inner channel, the indicator body comprising an opening contiguous with the inner channel and configured to receive the syringe body, the opening having a width slightly smaller than a diameter of the syringe body such that the syringe body is retained within the inner channel, the indicator body further comprising inflation indicia configured to correspond to a volume of fluid within the syringe;
- a window portion extending through a thickness of the indicator body,
- an engagement element disposed at a first end portion of the indicator body, the first engagement element extending from an inner surface of the indicator body into a thickness of the indicator body;
- and
- wherein the engagement element is configured to engage a corresponding engagement element of the syringe body to restrain the indicator body from rotational and axial movement relative to the syringe body.
A kit of volume indicators for a syringe having a syringe body and a plunger received in the syringe body, each volume indicator comprising:
- an elongated indicator body having a C-shape in cross section defining an inner channel, the indicator body comprising an opening contiguous with the inner channel and configured to receive the syringe body, the opening having a width slightly smaller than a diameter of the syringe body such that the syringe body is retained within the inner channel, the indicator body further comprising inflation indicia configured to correspond to a volume of fluid within the syringe;
- a window portion extending through a thickness of the indicator body,
- an engagement element disposed at a first end portion of the indicator body, the first engagement element extending from an inner surface of the indicator body into a thickness of the indicator body;
- and
- wherein the engagement element is configured to engage a corresponding engagement element of the syringe body to restrain the indicator body from rotational and axial movement relative to the syringe body.
