摘要： Apparatus for delivering brachytherapy to a target tissue region includes an elongate body including a proximal end, a distal end sized for introduction into a tissue tract and carrying a plurality of elongate members including pathways for receiving a source of radiation. The elongate members are movable between collapsed and expanded configurations. During use, a tract is created through tissue, and the elongate body carrying the elongate members is advanced through the tract into a target location with the elongate members in the collapsed configuration. The elongate members are directed to the expanded configuration at the target location, and radiation is delivered to treat tissue at the target location, e.g., by introducing one or more radiation sources along the pathways.

摘要： Apparatus, systems, and methods are provided for delivering brachytherapy into a target tissue region, e.g., a breast. In some embodiments, a flexible brachytherapy device is implanted that includes a therapy delivery portion having one or more radioactive sources securely retained thereto, and a tail portion extending from the therapy delivery portion. The brachytherapy device may be implanted in a helical configuration within the target tissue region. To assist in placement and removal of the brachytherapy device, a tubular sheath may be implanted by attaching (e.g., sliding over) a helically coiled needle that is advanced into the body by screw-like rotation. Once implanted, the sheath and the brachytherapy device may extend outside the body, where they may be folded and secured flat against the skin. The device and sheath may be removed at therapy completion.

摘要： A flexible, preferably coiled wire for use in small-vessel vaso-occlusion. The wire has a stretched, linear condition in which it can be advanced through a catheter lumen to a selected vessel, and a relaxed, convoluted condition produced by a combination of a helical winding of the wire, and irregularities of the helical winding. When the wire is released from a catheter into a vessel, it assumes a randomly coiled, substantially space-filling mass which is lodged at the site of release. In a preferred embodiment, the helical winding in the wire's relaxed condition has about the same diameter as that of the vessel, and the wire, in its stretched condition, has a length of about 15-20 times the vessel diameter.

摘要： Implantable devices and methods of use are disclosed for marking the location of a biopsy or surgery for the purpose of identification. The methods include providing a biodegradable radiodense implant and taking a tissue sample from a biopsy site within a breast of a patient. The biodegradable implant is then positioned at the biopsy site. The tissue sample is tested and the biopsy site is then relocated. In one embodiment, the entire implant is radiodense. In another embodiment, the entire implant is biodegradable. Methods of using a biodegradable implant having a radiodense material and a biodegradable implant that is visible using an imaging system are also included.

摘要： An innovative bone anchor and methods for securing connective tissue, such as tendons, to bone are disclosed which permit a suture attachment which lies entirely beneath the cortical bone surface, and wherein the suturing material between the connective tissue and the bone anchor is oriented in a direction generally transverse to the longitudinal axis of the bone anchor, so that axial pull-out forces exerted on the bone anchor are minimized. The suture attachment to the bone anchor involves the looping of a substantial length of suturing material around a shaft of the anchor, thereby avoiding an eyelet connection which requires a knot and which concentrates stress on a very small portion of the suturing material. Thus, failure rates are greatly decreased over conventional techniques, and the inventive procedures are significantly easier to perform than conventional techniques.
摘要翻译：公开了一种创新的骨锚和用于将结扎组织（例如腱）固定到骨的方法，其允许完全位于皮层骨表面下方的缝合线附件，并且其中结缔组织和骨锚之间的缝合材料定向成通常横向于骨锚的纵向轴线的方向，使得施加在骨锚上的轴向拉出力最小化。与骨锚固件的缝合线附件涉及围绕锚固件的轴的相当长度的缝合材料的环绕，从而避免需要结并且将紧张集中在缝合材料的非常小部分上的孔眼连接。因此，与常规技术相比，故障率大大降低，并且本发明的程序比常规技术更容易执行。
