MRI biopsy device
A compression assembly for retaining a patient's breast during a biopsy procedure that provides a wide variety of potential access points through which tissue may be accessed by a biopsy device.
1 . A compression assembly comprising:
(a) a frame; and
(b) a plurality of removable compression members positioned within said frame, where said removable compression members are engaged with said frame with at least one disengagable member, where disengaging said at least one disengagable member releases said compression member such that an access point is created through which a clinician may access a patient's breast.
2 . The assembly of claim 1 , wherein said frame is substantially rectangular in shape.
3 . The assembly of claim 1 , wherein said frame and said removable compression members are constructed from a polycarbonate stabilized for gamma irradiation.
4 . The assembly of claim 1 , wherein said removable compression members are compression plates.
5 . The assembly of claim 4 , wherein said removable compression members are provided with said at least one disengagable member on each side thereof.
6 . The assembly of claim 1 , wherein said removable compression members are compression bars.
7 . The assembly of claim 6 , wherein said compression bars are coupled at each end thereof to said frame with said at least one disengagable member.
8 . The assembly of claim 7 , wherein said compression bars are operably configured to be reattached to said frame.
9 . The assembly of claim 1 , wherein said disengagable member is removable from said compression assembly.
10 . The assembly of claim 1 , wherein said disengagable member is removable from a portion of said compression assembly.
11 . The assembly of claim 10 , wherein said disengagable member is removable from said frame and is retained upon said compression member.
12 . The assembly of claim 1 , wherein said removable compression members are reattachable.
13 . A compression assembly comprising:
(a) a frame; and
(b) a plurality of adjustable compression members positioned within said frame, where said adjustable compression members are engaged with said frame such that at least one said adjustable compression member is slidable therein, where adjusting at least one said compression member opens an access point to a patient's breast.
14 . The assembly of claim 13 , wherein said frame is substantially rectangular.
15 . The assembly of claim 13 , wherein said frame and said adjustable compression members are constructed from a polycarbonate stabilized for gamma irradiation.
16 . The assembly of claim 13 , wherein said adjustable compression members are movable members.
17 . The assembly of claim 16 , wherein said adjustable compression members are substantially rectangular in shape and are divided about at least two planes such that they may be adjusted about said planes to expose access points to a patient's breast.
18 . The assembly of claim 16 , wherein said adjustable compression members are substantially fan-shaped and are movable about a plurality of planes, where each compression member is movable about a separate plane.
19 . The assembly of claim 13 , wherein said adjustable compression members include one or a plurality of telescoping members.
20 . The assembly of claim 13 , further comprising at least one fixed compression member.
21 . A compression assembly comprising:
(a) a frame; and
(b) a plurality of adjustable compression members positioned within said frame, where said adjustable compression members are fixed to said frame and include one or a plurality of flexible members operably configured to allow for movement of said adjustable compression members such that access points to a patient's breast may be made available.
