Sterile cover for intraoperative ultrasonic diagnostic devices and method and kit for providing same

Claim 3

The method according to claim 1, wherein said one end of said sleeve is tapered to define the opening at said one end of said sleeve to have a circumference shorter than the circumference of the remainder of said sleeve, and wherein said placing step includes placing said sleeve onto said probe and said cable by inserting said probe into the end of said sleeve opposite from said one end and drawing said sleeve over said probe and over said cable until the tapered portion of said sleeve at said one end engages a tapered shape of said probe.

Claim 4

The method according to claim 1, further comprising the steps of rolling up said sheath prior to placing it on said probe, and placing said sheath on said probe by positioning a tip of said sheath on said distal end of said probe and unrolling said sheath over said probe and over said one end of said sleeve.

Claim 5

The method according to claim 1, further comprising the step of applying sound conducting jelly to said distal end of said probe or to the interior of a tip of said sheath prior to said placing said sheath over said distal end.

Claim 6

The method according to claim 1, further comprising the step of banding an end of said sleeve that is opposite from said one end of said sleeve.

Claim 7

The method according to claim 1, wherein said sheath covers all of said probe and a portion of said connecting cable, further comprising the step of banding said sheath at a portion of said sheath which covers said cable.

Claim 8

The method according to claim 1, further comprising the steps of applying an outer sheath over said sheath after first applying sound conducting jelly to the exterior of a tip of said sheath or the interior of a tip of said outer sheath.

Claim 9

The method according to claim 1, further comprising the step of removing and discarding said sheath and said sleeve after a sonic imaging procedure has been completed.

Claim 10

A kit for providing a sterile cover over a sonic probe having a distal end with a predetermined shape and the cable connecting said probe to a sonic imaging instrument, said kit comprising: a sleeve tapered at one end to define an opening at said one end substantially smaller than the passage through the remainder of said sleeve, said taper being shaped to correspond with the shape of the distal end of said probe, said sleeve being sufficiently flexible to bend to a substantial degree of curvature without damage, being open at both ends and having a sterile exterior surface; a sheath at one end and closed at another end and having a sterile exterior surface; and a package having a sterile interior, said package enclosing said sleeve and said sheath so that the sterile condition of said sheath and sleeve is maintained, wherein said sleeve is adapted to cover at least a portion of said cable and all but said distal end of said probe and said sheath is adapted to fit over a portion of said sleeve and cover at least said distal end of said probe, the closed end of said sheath being shaped to fit with the distal end of said probe and correspond to the shape of the tapered end of said sleeve so that the tapered end of said sleeve and the closed end of said sheath fit together when mounted on said probe.

Claim 11

A kit for providing a sterile cover over a sonic probe having a distal end with a predetermined shape and the cable connecting said probe to a sonic imaging instrument, said kit comprising: a sleeve tapered at one end to define an opening at said one end substantially smaller than the passage through the remainder of said sleeve, said taper being shaped to correspond with the shape of the distal end of said probe, said sleeve being sufficiently flexible to bend to a substantial degree of curvature without damage, being open at both ends and having a sterile exterior surface; a sheath at one end and closed at another end and having a sterile exterior surface; and a package having a sterile interior, said package enclosing said sleeve and said sheath so that the sterile condition of said sheath and sleeve is maintained, wherein said sleeve is adapted to cover at least a portion of said cable and all but said distal end of said probe and said sheath is adapted to fit over a portion of said sleeve and cover at least said distal end of said probe, the closed end of said sheath being shaped to fit with the distal end of said probe and correspond to the shape of the tapered end of said sleeve so that the tapered end of said sleeve and the closed end of said sheath fit together when mounted on said probe.

Claim 12

The kit according to claim 9, wherein said sleeve is tapered at one end adapted to be adjacent to said distal end of said probe, such that the tapered portion of said sleeve mates with a tapered shape of said probe.

Claim 13

The kit according to claim 9, wherein said sheath is elastomeric and produced in a molding process without use of a powdiferous releasing agent.

Claim 14

The kit according to claim 9, further comprising an amount of sound conducting jelly enclosed in said package, said jelly adapted to be applied between said distal end and at least a tip of said sheath.

Claim 15

The kit according to claim 9, wherein said sheath is adapted to cover all of said probe and at least a portion of said cable, and wherein said kit further comprises a first band adapted to constrict a portion of said sheath that covers said cable.

Claim 16

The kit according to claim 13, further comprising a second band adapted to constrict an end of said sleeve that is opposite to said one end.

Claim 17

The kit according to claim 9 wherein said open end of said sheath comprises an O-ring.

Claim 18

The kit according to claim 9, further comprising an outer sheath adapted to cover at least a tip of said sheath.

Claim 19

The kit according to claim 9 wherein a tray is provided with recesses which correspond to component parts of said kit to hold said parts.

Claim 20

The kit according to claim 17 wherein a recess in said tray for said sheath maintains a tip of said sheath in an inverted, open position so that sound conducting jelly can be dispensed into said tip while the sheath is disposed in said tray.
