The invention relates to a cutting device for cutting foam sheets, and more particularly, the invention relates to a cutting device for cutting sheets of compressed hemostatic foam.
Bioabsorbable hemostatic foam is used in the medical field to promote hemostasis in many different applications. Two examples of applications in which hemostatic foam is delivered through a cannula are described in International Publication Nos. WO99/56692 and WO99/56632 which are incorporated herein by reference in their entirety. As described in these applications, a pledget of compressed hemostatic foam is cut from a sheet of the foam material and is rolled or folded into a configuration which is inserted into a delivery device. Once the foam pledget is inserted into the delivery device, the foam is hydrated and delivered to a body for promoting hemostatis.
Cutting the compressed hemostatic foam (such as Pharmacia Upjohn Gelfoam) is difficult and awkward. Although cutting the foam with a template and a cutting device, such as a knife is possible, it would be desirable to have a cutting device that can quickly and easily cut a piece of foam of a predetermined size and shape.
The present invention relates to a cutting device for cutting shapes from sheets of material, such as sheets of compressed hemostatic foam. The present invention also relates to a kit for delivering hemostatic foam including a cutting device.
In accordance with one aspect of the present invention, a cutting device includes a base having an opening with cutting edges; and a flap articulated with respect to the base, the flap having a shape corresponding to the opening and cutting edges corresponding to the cutting edges of the opening.
In accordance with another aspect of the present invention, a cutting device includes a base having an opening with cutting edges; a flap articulated with respect to the base, the flap having a shape corresponding to the opening and cutting edges corresponding to the cutting edges of the opening; and wherein the base is mounted on a card, and the card supports a medical device system.
In accordance with further aspect of the present invention, a medical kit includes a sheet of medical foam material; and a cutter for cutting the foam material, the cutter includes a base having an opening with cutting edges, and a flap articulated with respect to the base for cutting foam.
In accordance with another aspect of the present invention, a kit for cutting sheets of material, the kit including a base having an opening with cutting edges; a flap articulated with respect to the base, the flap having a shape corresponding to the opening and cutting edges corresponding to the cutting edges of the opening; and a presentation card which supports at least one medical device.
In accordance with a further aspect of the present invention, a method of cutting foam sheets includes the steps of placing a piece of foam underneath an articulate edge of a cutting device; and pushing down the articulated edge to cut the piece of foam between the edges of the articulated flap and an edge of an opening on a base of the cutting device.
In accordance with another aspect of the present invention, a medical system includes a sheet of medical foam material; and a cutter for cutting the foam material, the cutter including a base having an opening with cutting edges, and a flap articulated with respect to the base for cutting foam.
The present invention provides a cutting device that can quickly and easily cut a piece of foam to a predetermined size and shape.
The invention will now be described in greater detail with reference to the preferred embodiments illustrated in the accompanying drawings, in which like elements bear like reference numerals, and wherein:
The easy cutter 10 of
It should be understood that the easy cutter according to the present invention may be used to cut any number of different shaped pieces of foam. The pieces which are cut may be cut on three sides as illustrated. Alternatively, the easy cutter may cut shapes which require cutting on 1, 2, 3, 4, or more sides of the shape. Other free form shapes such as stars and other polygons may also be cut depending on the particular application.
The easy cutter according to the present invention is particularly designed to be used in a kit including medical devices for delivery of a hemostatic sponge material. However, it should be understood that the easy cutter may also be used for cutting many different materials in both medical and non-medical applications.
When the easy cutter is used for medical applications it is a sterile single use device or a device which may be cleaned, resterilized, and reused. For non-medical applications the easy cutter may be unsterilized.
The term foam as used herein is intended to mean a biocompatible material which is capable of being hydrated and is resiliently compressible in a hydrated state. Preferably, the foam is non-immunogenic and may be absorbable or non-absorbable.
While the invention has been described in detail with reference to the preferred embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made and equivalents employed, without departing from the present invention.
This application claims priority to provisional U.S. application Ser. No. 60/200,702 filed Apr. 28, 2000, which is incorporated herein by reference in its entirety.
