Abstract
Abstract A breast biopsy device is provided which includes a localization needle having a guide wire preloaded into the biopsy device. The device includes a stylet having a blade for transecting and separating healthy tissue on route to the biopsy site. The use of the stylet blade reduces the trauma to healthy breast tissue. The device further includes a cannula blade and a garrote for forming a cut transverse to the core cut by the cannula blade. A lockout feature prevents the garrote from deploying until after a cutting plane of the garrote has been advanced beyond the end of the guide wire.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
182 words
A device for removing suspect breast tissue comprising: a stylet mounted on a retracting handle, said stylet having a tip containing a plurality of blades for transecting tissue and a central passage capable of receiving a localization needle; a cannula mounted on a drive mechanism, said cannula having a shaft that supports a cutting surface opposite said drive mechanism; said drive mechanism for simultaneously rotating said cannula and moving said cannula in a direction that is transverse to the rotation of said cannula; a garrote for performing a cut transverse to the longitudinal axis of the cannula, said garrote mounted adjacent to said cutting surface of said cannula; a trigger for deploying said garrote, said trigger including a locking mechanism for preventing deployment of said garrote prior to movement of said cannula a predetermine distance, said locking mechanism has a locked position and an unlocked position, in the locked position the trigger abuts a trigger stop and in the unlocked position a ramp lifts the trigger above the trigger stop; and a localization needle having a guide wire mounted within said needle.
Claim 2
Independent Claim
182 words
A device for removing suspect breast tissue comprising: a stylet mounted on a retracting handle, said stylet having a tip containing a plurality of blades for transecting tissue and a central passage capable of receiving a localization needle; a cannula mounted on a drive mechanism, said cannula having a shaft that supports a cutting surface opposite said drive mechanism; said drive mechanism for simultaneously rotating said cannula and moving said cannula in a direction that is transverse to the rotation of said cannula; a garrote for performing a cut transverse to the longitudinal axis of the cannula, said garrote mounted adjacent to said cutting surface of said cannula; a trigger for deploying said garrote, said trigger including a locking mechanism for preventing deployment of said garrote prior to movement of said cannula a predetermine distance, said locking mechanism has a locked position and an unlocked position, in the locked position the trigger abuts a trigger stop and in the unlocked position a ramp lifts the trigger above the trigger stop; and a localization needle having a guide wire mounted within said needle.
Claim 3
Dependent Claim
20 words
The device for removing suspect breast tissue of claim 1, wherein said guide wire is movable within the localization needle.
Claim 4
Dependent Claim
34 words
The device for removing suspect breast tissue of claim 2, wherein the locking mechanism prevents deployment of the garrote until a cutting plane of the garrote is beyond an end of the guide wire.
Claim 5
Dependent Claim
29 words
The device for removing suspect breast tissue of claim 2, wherein the guide wire includes a hook that anchors one end of the guide wire in the breast tissue.
Claim 6
Dependent Claim
21 words
The device for removing suspect breast tissue of claim 2, further comprising means for preventing premature deployment of the guide wire.
Claim 7
Dependent Claim
21 words
The device for removing suspect breast tissue of claim 1, wherein the ramp moves along a longitudinal axis of the device.
Claim 8
Dependent Claim
34 words
The device for removing suspect breast tissue of claim 1, wherein when the trigger is in the unlocked position, the trigger can be advanced to deploy the garrote and cut a plug of tissue.
Claim 9
Dependent Claim
37 words
The device for removing suspect breast tissue of claim 1, wherein the locking mechanism is moved from a locked position to an unlocked position by rotation of a gear member which causes longitudinal motion of a spline.
Claim 10
Dependent Claim
27 words
The device for removing suspect breast tissue of claim 8, wherein the rotation of the gear member also advances the cannula to cut a core of tissue.
Claim 11
Independent Claim
173 words
A device for removing suspect breast tissue comprising: a stylet mounted on a retracting handle, said stylet having a tip containing a plurality of blades for transecting tissue and a central passage capable of receiving a localization needle; a cannula mounted on a drive mechanism, said cannula having a shaft that supports a cutting surface opposite said drive mechanism; said drive mechanism for simultaneously rotating said cannula and moving said cannula in a direction that is transverse to the rotation of said cannula; a garrote for performing a cut transverse to the longitudinal axis of the cannula, said garrote mounted adjacent to said cutting surface of said cannula; a trigger for deploying said garrote, said trigger including a locking mechanism for preventing deployment of said garrote prior to movement of said cannula a predetermine distance, said locking mechanism is moved from a locked position to an unlocked position by rotation of a gear member which causes longitudinal motion of a spline; and a localization needle having a guide wire mounted within said needle.
Claim 12
Independent Claim
173 words
A device for removing suspect breast tissue comprising: a stylet mounted on a retracting handle, said stylet having a tip containing a plurality of blades for transecting tissue and a central passage capable of receiving a localization needle; a cannula mounted on a drive mechanism, said cannula having a shaft that supports a cutting surface opposite said drive mechanism; said drive mechanism for simultaneously rotating said cannula and moving said cannula in a direction that is transverse to the rotation of said cannula; a garrote for performing a cut transverse to the longitudinal axis of the cannula, said garrote mounted adjacent to said cutting surface of said cannula; a trigger for deploying said garrote, said trigger including a locking mechanism for preventing deployment of said garrote prior to movement of said cannula a predetermine distance, said locking mechanism is moved from a locked position to an unlocked position by rotation of a gear member which causes longitudinal motion of a spline; and a localization needle having a guide wire mounted within said needle.
Claim 13
Dependent Claim
