摘要： There is disclosed, among other things, embodiments of a biopsy needle for taking a full core sample through soft tissue. In the illustrated embodiments, the needle includes a single monolithic tubular member having a notch cut part-way through a distal portion of the tubular member to form an arch-shaped finger. At least a portion of the finger is bent toward the notch and into the lumen of the tubular member. Methods for using these embodiments are also described.

摘要： Among other things, there are disclosed embodiments of full-core biopsy needles having an outer needle component and a middle cannula through a lumen in the outer component, through which a mandrel may be placed. The outer component includes an internal boss that reduces its internal diameter, and the cannula includes fingers that extend distally. When the needle is inserted for biopsy, tissue enters the outer component and cannula. Moving the cannula forward causes the fingers to engage a surface of the internal boss, resulting in the fingers curving into the tissue. The fingers pinch the tissue while reducing or eliminating compression of the sample to provide an easier removal of the tissue from adjacent tissue, as well as providing a block or backstop keeping the tissue within the needle. Gaps are provided between the fingers to further reduce damage to the tissue sample.

摘要： An endoluminal prosthesis that includes a support structure comprising a curvilinear portion having a first strut and a second strut that meet at an apex. Disposed on the support structure is an anchor with an anchor body and one or more barbs extending outwardly from the anchor body and where the anchor body comprises a multi-filar tube fits at least partially about, and conforms to the first strut, second strut, and the apex.

摘要： Certain aspects of the present invention provide devices for occluding vascular vessels. In some preferred forms, these devices are able to move from a first condition to a less compact, second condition in a vascular vessel so as to fully or partially prevent fluid from passing through the vessel. One such device includes a frame and a flexible sheet material. The device also includes an occluding material that is located in an interior region of the frame. The flexible sheet material and frame are associated with one another such that when the device is in the second condition in the vascular vessel, the sheet material is positioned in the vessel lumen so as to block fluid flow through the lumen.
摘要翻译： 本发明的某些方面提供用于阻塞血管的装置。 在一些优选的形式中，这些装置能够在血管容器中从第一状态移动到较不致密的第二状态，以便完全或部分地防止流体通过血管。 一种这样的装置包括框架和柔性片材。 该装置还包括位于框架的内部区域中的阻塞材料。 柔性片材和框架彼此相关联，使得当装置在血管容器中处于第二状态时，片材材料被定位在血管腔中，以阻止流体流过管腔。
