Abstract

A sterile cover assembly is for a biopsy device. The biopsy device includes a reusable holster including a housing and driving mechanism. The driving mechanism is for driving a cutter in a needle of a probe. The housing is adapted to releasably couple to the probe. The sterile cover assembly includes a sleeve and a flexible sterile cover. The sleeve is configured to receive at least a portion of the housing of the reusable holster. The sterile cover is coupled to the sleeve and is configured to cover the housing of the holster.

First claim

We claim:

1. A sterile cover assembly for a biopsy device having a reusable holster including a housing and driving mechanism for driving a cutter in a needle of a probe, the housing adapted to releasably couple to the probe, the sterile cover assembly comprising:
a sleeve, wherein the sleeve is configured to receive at least a portion of the housing of the reusable holster; and
a flexible sterile cover coupled to the sleeve and configured to cover the housing of the holster such that the sleeve and the flexible sterile cover are initially layered over one another on the housing, wherein the sleeve is more rigid than the sterile cover.

2. The sterile cover assembly of claim 1 , wherein the sleeve includes an interface opening, a distal opening, a proximal opening, and an inner channel extending between the distal opening and the proximal opening, wherein the interface opening is configured to provide access to one or more buttons on the housing of the holster through the flexible sterile cover.

3. The sterile cover assembly of claim 1 , wherein the sleeve includes an interface opening, a distal opening, a proximal opening, and an inner channel extending between the distal opening and the proximal opening, wherein the interface opening is configured to provide access to one or more buttons on the housing of the holster through the flexible sterile cover, wherein the inner channel of the sleeve is sized and shaped to receive the holster, wherein a first length of the sleeve is less than a second length of the holster such that a portion of the holster extends proximally from the proximal opening of the sleeve when the holster is received within the inner channel of the sleeve.

4. The sterile cover assembly of claim 1 , wherein the sleeve includes an outer retainer and an inner retainer, wherein the inner retainer is configured to nest within the outer retainer so as to sandwich the flexible sterile cover therebetween.

5. The sterile cover assembly of claim 1 , wherein the sleeve includes an outer retainer and an inner retainer configured to nest within the outer retainer so as to sandwich the flexible sterile cover therebetween, wherein each of the outer and inner retainers includes an interface opening, wherein the interface opening of the outer retainer is configured to align with the interface opening of the inner retainer to permit access to one or more buttons on the housing of the holster through the outer retainer, the flexible sterile cover, and the inner retainer.

6. The sterile cover assembly of claim 1 , wherein the flexible sterile cover is configured to cover a cable extending from the holster for a predetermined length, wherein the predetermined length is at least one foot.

7. The sterile cover assembly of claim 1 , wherein the sleeve includes an outer retainer and an inner retainer configured to nest within the outer retainer so as to sandwich the flexible sterile cover therebetween, wherein the length of each of the outer retainer and the inner retainer is less than the length of the holster such that the outer retainer and the inner retainer only cover a portion of the holster when the holster is received within the inner retainer and the outer retainer.

8. The sterile cover assembly of claim 1 , wherein the flexible sterile cover includes a latex sterile cover that has a thickness of 3 mm or less.

9. The sterile cover assembly of claim 1 , wherein the flexible sterile cover includes a distal closed end, a proximal open end, and an inner channel, wherein a length defined by the inner channel is greater than a length defined by the holster such that the flexible sterile cover extends proximally from a proximal end of the holster when the sleeve and the holster are received within the inner channel of the flexible sterile cover.

10. The sterile cover assembly of claim 1 , further comprising a sleeve ring attached to a proximal end of the flexible sterile cover and at least a portion of the flexible sterile cover is disposed on the outside of the sleeve ring in a folded configuration to be unfolded over the housing of the holster by a user.

11. The sterile cover assembly of claim 1 , wherein the sleeve includes an outer retainer and an inner retainer, wherein the inner retainer is configured to nest within the outer retainer so as to sandwich the flexible sterile cover therebetween, further comprising a sleeve ring attached to a proximal end of the flexible sterile cover and at least a portion of the flexible sterile cover is disposed on the outside of the sleeve ring in a folded configuration to be unfolded over the housing of the holster by a user, wherein the flexible sterile cover extends proximally from the distal end of the sleeve between the outer and inner retainer, then distally over the outer retainer, then proximally over the sleeve ring.

12. The sterile cover assembly of claim 1 , further comprising a sleeve ring attached to a proximal end of the flexible sterile cover to allow manipulation of the flexible sterile cover to cover the housing of the holster.

13. The sterile cover assembly of claim 1 , further comprising a sleeve ring defining a sheath portion and a horn portion, wherein the sheath portion is configured to receive the flexible sterile cover in a folded configuration, wherein the horn portion is flared relative to the sheath portion.

14. The sterile cover assembly of claim 1 , further comprising a sleeve ring defining a tab and an opening disposed adjacent to the tab, wherein the tab and the opening are configured to releasably receive a proximal end of the flexible sterile cover.

15. The sterile cover assembly of claim 1 , further comprising a sleeve ring configured to releasably couple to a proximal end of the flexible sterile cover to manipulate the proximal end of the flexible sterile cover, wherein the sleeve ring is an open ring and includes a locking relief slot to permit the sleeve ring to flex to reduce the ring size and to increase the ring size when the locking relief slot is locked.

16. A biopsy device comprising:
(a) a holster;
(b) a probe configured to couple to the holster;
(c) a needle extending from the probe; and
(d) a removable cover assembly couplable to the holster, wherein the removable cover assembly is configured to substantially cover the holster, wherein the removable cover assembly includes:
(i) an inner sleeve retainer configured to receive a portion of the body,
(ii) an outer sleeve retainer configured to receive the inner sleeve retainer, and
(iii) a flexible sterile cover configured to cover a portion of the body, wherein the inner sleeve retainer is configured to nest within the outer sleeve retainer so as to sandwich the flexible sterile cover therebetween.

17. The biopsy device of claim 16 , wherein the removable cover assembly further includes a sleeve ring configured to fasten to a proximal end of the flexible sterile cover, wherein the sleeve ring defines a d-shaped cross-section configured to encompass the inner sleeve retainer and the outer sleeve retainer.

18. The biopsy device of claim 16 , wherein the removable cover assembly further includes a sleeve ring defining a plurality of tabs, wherein each tab of the plurality of tabs is configured to engage a proximal end of the flexible sterile cover to fasten the flexible sterile cover to the sleeve ring.

19. The biopsy device of claim 16 , wherein the removable cover assembly further includes a flexible sleeve, wherein the flexible sleeve defines a closed distal end, an open proximal end, and a manipulator, wherein the m
