A graft having a tubular body having a first end configured for attachment to a first vessel having a first compliance and second end configured for attachment to a second vessel having a second compliance different from the first compliance, and having a plurality of compressible chambers in the wall of the tubular body in which the chamber adjacent the first end of the tubular body is less compressible than the chamber adjacent the second end of the tubular body such that first end of the tubular body substantially matches the first compliance and the second end of the tubular body substantially matches the second compliance.

Vascular graft with compartments for compliance matching

An intravascular medical device is prepared for shipping by being sealed within a sterile volume of a package. Prior to closing the package, an intravenous liquid solution is pumped into and through the medical device to displace all air bubbles. The liquid is pumped at sterilization temperatures corresponding to when the liquid has a low viscosity, but the liquid is chosen to have a relatively high viscosity at room temperatures corresponding to when the package is opened for use. The liquid solution remains adsorbed to the interior surfaces of the medical device at room temperature against a force of gravity. The strategy reduces the risk of air embolism when a medical device is put into use.

Packaged intravascular medical device with variable viscosity intravenous liquid solution

A graft for inducing helical blood flow, including a tubular body with fluid inflow and fluid outflow ends, and with inner and outer sidewalls. A lumen extends between the fluid inflow end and fluid outflow end. A compressible chamber is disposed between the outer sidewall and the inner sidewall. The compressible chamber has an incompressible seam that follows a substantially helical path around a longitudinal axis of the tubular body. When internal (e.g., blood) pressure increases on the inner sidewall, a vane element is formed that follows the substantially helical path around the longitudinal axis of the tubular body. The vane element may induce helical blood flow. The width of the compressible chamber may decrease in a compressed state (e.g., systole). The chamber may be filled with a predetermined amount of at least one of a gas, liquid, or vapor. The graft may have a second incompressible seam/vane.

Vascular graft with helical flow compliance compartments

A needle disclosed herein may include an elongate body extending between a proximal end and a distal end with a central longitudinal axis defined by the body, where the distal end includes a single sharp point along the central longitudinal axis and defining a distal end terminus three longitudinal fluted surfaces converging at the distal end terminus; and three longitudinal beveled cutting edges defining borders between the fluted surfaces and converging at the distal end terminus. Needle embodiments may include one or more ports open into and/or proximal of the fluted surfaces and communicating with one or more longitudinal needle lumens.

Tri-fluted vascular access needle

An expandable endoluminal prosthesis may include a graft body and a support structure attached to the graft body. The graft body may include a tubular body of nonwoven electrospun fibers disposed about a longitudinal axis. A first fiber matrix segment may be attached to and extend in a transverse direction along the tubular body. A second fiber matrix segment may be attached to and extend in a longitudinal direction along the tubular body.

Endoluminal prosthesis with fiber matrix

Biopsy devices and methods are provided for collecting a sufficiently-sized tissue sample from a region at a known distance by boring into the sample region using simultaneous axial and rotational movement and providing a reduced risk of: over-passing or under-passing the sample sought, injury and trauma to the surrounding tissue area, having to stick the patient more than once, sample contamination, and the user's exposure to sharps.

Coring tissue biopsy needle and method of use

An aortic stent-graft may include a tubular graft extending from a proximal end to a distal end, the graft comprising a proximal sealing portion and an intermediate portion, wherein a proximal end of the intermediate portion abuts the distal end of the proximal sealing portion. At least one sealing stent may be attached to the proximal sealing portion. A first fenestration window is disposed in the intermediate portion. The first fenestration window has a length determined by the equation L=1.23*D&#x2212;24 millimeters, where L is the length of the first fenestration window. D is between about 24 millimeters and 45 millimeters.

Medical device delivery system and deployment method

A method for bonding a graft material to a support element employing a silane coupling agent, and a medical device obtainable by the method. A medical device including a graft material bound to a support element by a plurality of silane linkages is also described.

Silane bonded medical devices and method of making same

Apparatus for facilitating deployment of a an implantable medical device includes a control member () having at least one tine member (-). A proximal region (-) of at least one of the tine members (-) is configured to engage an associated portion of a stent (). In use, the control member () comprises a contracted delivery configuration in which the proximal region of the at least one of the tine member (-) is radially contracted, to radially constrain the associated portion of the stent (). The control member () also comprises an expanded configuration in which the proximal region of the at least one of the tine member (-) expands radially outward relative to the central longitudinal axis to allow the stent to engage a body passage.

Apparatus and methods for improved stent deployment

An endoluminal prosthesis and systems and methods for making the prosthesis are provided. In one example, a patterned graft material for a prosthesis includes a network of electrospun fibers. The network of electrospun fibers may include a plurality of continuous electrospun fibers. The fibers may be collected on a collector plate using an electrospinning process to form the network of fibers. The patterned graft material also may include a plurality of openings in the network of electrospun fibers. The plurality of openings may be arranged in a pattern. The network of electrospun fibers may include a plurality of edges, each surrounding a corresponding one of the plurality of openings. Each of the plurality of edges may include at least one electrospun fiber of the network of electrospun fibers. A majority of the electrospun fibers of the plurality of edges may be continuous at the edges.

Electrospun patterned stent graft covering

A delivery and deployment device comprises a sheath having a proximal end, a distal end, and a lumen disposed therebetween; a dilator having a distal end slidingly disposed within the sheath lumen; a valve assembly comprising a valve housing affixed to the sheath and a valve disposed within the housing between the sheath and the dilator; and a valve lubrication mechanism disposed between the valve and the dilator.
