    摘要: An introducer assembly for introducing a stent-graft or other device into a vessel of a patient is provided with a dilator tip which is naturally curved, preferably to be substantially a U-shape. The dilator tip is flexible so as to be able to become substantially straight with a guide wire therein and yet to be able to curve back towards its natural curvature during deployment of an implant. The curvature of the dilator tip can ensure that the dilator tip does not cause damage to the vessel wall during deployment of an implant carried thereon, as can occur with straight dilator tips.

    摘要: Disclosed are multi-chambered cell co-culture systems. The systems can be utilized to encourage the growth and development of isolated cells in a dynamic three-dimensional in vitro environment. The cell chambers (10) of the system can be in biochemical communication with adjacent chambers containing cells of different types, but the different cell types are maintained physically separated from one another. In addition, the local environment of each cell chamber can be independently controlled. For example, fluid flow characteristics through a single cell chamber can be independently controlled and maintained for each separate chamber of the system.

    摘要: An electrospinning apparatus may include a first spinneret and a second spinneret, each including a reservoir and an orifice. The first and second spinnerets may have first and second electrical charges, respectively. The first spinneret orifice may be located substantially opposite the second spinneret orifice. The first and second spinnerets may be used to prepare a medical device defining a lumen with a proximal end, a distal end, a luminal surface and an abluminal surface. The first spinneret orifice distal end may be configured to be located outside of the medical device lumen and between about 0.1 inches and about 6.0 inches from the medical device abluminal surface. The second spinneret orifice distal end may be configured to be located in the medical device lumen and between about 0.1 inches and about 6.0 inches from the medical device luminal surface.

    摘要: There are disclosed apparatus and methods for treating tissue by delivering at least one therapeutic agent into the tissue. In one embodiment, the apparatus comprises a catheter (30, 40) and a balloon member (150) disposed on a distal region of the catheter. A plurality of pockets (164) are disposed on the balloon member (150), and a plurality of needles (180) are associated with each of the plurality of pockets. The plurality of needles (180) are configured to engage tissue when the balloon (150) is in the inflated state, and further are configured to disperse a therapeutic agent from an associated pocket (164) into the tissue when the balloon (150) is in the inflated state. A first needle (180a) of the plurality of needles may comprise a length that is different than a second needle (180b), permitting the delivery of first and second therapeutic agents to different depths within the tissue.
