    • An attachable needle storage device is provided with a main body and a rotatable sleeve and a plurality of new needles stored within the sleeve, a leaf spring to direct each needle into a circumferential position of the pen body when rotated, and a ramp to move the needle into an axial position of the pen body when retracted or pulled rearward by the user. The attachable needle storage device is configured to attach to a pen device in a manner substantially the same as a conventional needle hub. In doing so, the rotation of the sleeve can be used to rotate a new needle onto a shuttle, and the retraction of the device can be used to cause a ramp to engage the needle and needle hub, moving the needle toward the axial position of the pen body and the septum. Once under the septum, the user continues pulling the device rearward, such that the needle is then moved rearward, pierces the septum of the medicament cartridge and exposes the distal end of the needle for injection. After use, a needle shield is used to unlock a compressed spring, which is configured to pull the needle from the septum, and return the device to the transport state, after which the previous steps can be repeated.
    • 可附接的针存储装置设置有主体和可旋转的套筒以及存储在套筒内的多个新的针,一个板簧,用于在转动时将每个针引导到笔体的圆周位置, 当用户收回或向后拉时,针头进入笔体的轴向位置。 可连接针存储装置被配置为以与常规针毂基本相同的方式附接到笔式装置。 在这样做时,套筒的旋转可以用于将新的针旋转到梭子上,并且装置的缩回可以用于引起斜面接合针和针座,使针朝着轴向位置移动 笔体和隔膜。 一旦在隔膜下方,用户继续向后拉动装置,使得针随后向后移动,刺穿药剂盒的隔膜并暴露注射针的远端。 使用后,使用针护罩来解锁压缩弹簧,压缩弹簧被配置为从隔膜拉动针头,并将装置返回到运输状态,之后可以重复前述步骤。

    • Immobilization and/or retrieval of material from a body can be accomplished, in accordance with the invention, with a device that includes a sheath and a basket. The basket is movable relative to the sheath from a retracted position in which the basket is withdrawn within the sheath and an expanded position in which the basket is extended beyond the distal end of the sheath and open. The basket has a first portion and a second portion with two or more legs extending from the first portion to the second portion. The basket further includes an intermediate portion between the first and second portions in which the legs are spirally arranged, substantially parallel, and non-intersecting. The intermediate portion of the basket is displaced radially outward relative to the first and second portions when the basket is in the expanded position. The basket in the expanded position may be used to immobilize and/or capture material within a body.
    • 根据本发明,可以使用包括护套和篮子的装置来实现来自身体的材料的固定和/或回收。 篮可以相对于护套从缩回位置移动,在缩回位置,筐在护套内被拉出,而扩展位置中筐延伸超过护套的远端并打开。 篮子具有第一部分和第二部分,其具有从第一部分延伸到第二部分的两个或多个腿部。 篮子还包括第一和第二部分之间的中间部分,腿部螺旋地布置在其中,基本上平行且不相交。 当篮子处于展开位置时,篮子的中间部分相对于第一和第二部分径向向外位移。 处于展开位置的篮子可以用于在身体内固定和/或捕获材料。

    • An embodiment of the invention includes a device for collecting body tissue. The device may include an inner member comprising a hollow portion to collect body tissue and a distal end configured to both penetrate body tissue and define an opening of the hollow portion. The device may further include an outer member, co-axially and slidably disposed around the exterior of the inner member, comprising a distal end portion. The distal end portion of the outer member may be configured to penetrate body tissue, prevent body tissue from exiting the hollow portion of the inner member, and allow the distal end of the inner member to extend beyond the distal end of outer member. The opening of the hollow portion of the inner member may be disposed in a plane that is not perpendicular to the longitudinal axis of the inner member.
    • 本发明的实施例包括用于收集身体组织的装置。 该装置可以包括内部构件,该内部构件包括用于收集身体组织的中空部分,以及构造成两者穿过身体组织并限定中空部分的开口的远端。 该装置还可以包括外部构件,其同轴且可滑动地设置在内部构件的外部,包括远端部分。 外部构件的远端部分可构造成穿透身体组织,防止身体组织离开内部构件的中空部分,并允许内部构件的远端延伸超出外部构件的远端。 内部构件的中空部分的开口可以设置在不垂直于内部构件的纵向轴线的平面中。
