Abstract: A target tissue localization device (28) has outer and inner members (30, 32) which are longitudinally movable relative to one another. An anchor (42) is secured to the outer and inner members and is movable from a radially-contracted configuration to a radially-expanded configuration. The anchor may be a tubular mesh anchor. The anchor may have a sufficiently large cross-sectional area when in the radially-expanded configuration to substantially eliminate inadvertent dislodgment of the anchor once radially-expanded. In use, the location of the target tissue (56) is determined and the distal end of the localization device is passed through the patient's skin (58) and to the target tissue to create a tissue track (60) between the patient's skin and the target tissue. The target tissue includes near and far sides (62, 64). The anchor element, located at the target tissue is expanded to an expanded configuration. The method the anchor element may be located on the far side of the target tissue.

Abstract: A biopsy localization device made according to the invention includes a bioabsorbable element (34), such as a dehydrated collagen plug, delivered in a pre-delivery state to a soft tissue biopsy site (18) of a patient by an element delivery device (32). The bioabsorbable element preferably swells to fill the biopsied open region (26) and preferably is palpably harder than the surrounding soft tissue at the biopsy site. The bioabsorbable element permits the biopsy site to be relocated by palpation to eliminate the need to use metallic clips during biopsies and often eliminates the need for a return to the radiologist for pre-operative localization. In addition, the bioabsorbable element can be used as a therapeutic tool for treatment of the diseased lesion and for hemostasis.

Abstract: A stent comprising varying porosity's for use in vessels with bifurcations or side branches. The stent allows for scaffolding of the stenotic area but still allows for flow into the side branches. A distal protection system is also described.
Abstract: Medical devices that have a novel mechanical trap(s) on the distal end of a shaft that is used for the removal of material from the body. Further an expandable channel is included to entrap the material that aid with removal or obliteration of tissue or foreign bodies is disclosed.
