Abstract:
In general, the invention features an intravascular device, a delivery system, and methods for filtering or deflecting emboli or other large objects from entering a protected secondary vessel or vessels The intravascular device of the invention may prevent passage of a particle in a blood vessel from passing through a filter supported by a frame, upper and lower stabilizers, and a wire. The wire may be used to stabilize the device upon its deployment and installation within a blood vessel. Further, in some embodiments, the invention features a delivery system and methods for introduction of the device into a blood vessel.
Abstract:
Amiular prostheses comprising an elongated tubular member formed from an extracellular matrix (ECM) composition comprising ECM from a mammalian tissue source, which, when disposed proximate damaged cardiovascular tissue, induces modulated healing, including modulation of inflammation and bioremodeling. The ECM can also be augmented with a supplemental biologically active agent, such as a growth factor, to enhance modulation of inflammation and bioremodeling.
Abstract:
A Y-Lock tracheal stent system consisting of a stent device, for emplacement in the larynx, and a stent delivery system. A method for employing the stent delivery system to emplace the stent device.
Abstract:
Anchored cardiovascular valves having a support member with at least one leaflet formed therein that is sized and configured to selectively restrict regurgitating blood through the valve, and at least one anchoring mechanism. In a preferred embodiment of the invention, the anchored valves have two anchoring mechanisms, i.e. proximal and distal anchoring mechanisms
Abstract:
An intraluminal device may be used at a bifurcation to anchor in an afferent vessel, allow perfusion to efferent vessels, and act as scaffolding to inhibit herniation of objects out of a neck of a bifurcation aneurysm. An intraluminal device may include a first side; a second side opposite the first side across a longitudinal axis of the intraluminal device; a proximal section configured to anchor in an afferent vessel; a distal section comprising a first wing and a second wing wherein, in an expanded state, the first wing extends from the first side to the second side and the second wing extends from the second side, through an opening of the first wing, and to the first side.
Abstract:
The present invention relates to an artificial hip joint replacement system. The system includes an acetabulum portion comprising a cup suitable to be received by a subject's acetabular bone. The cup includes a rigid portion and an elastic portion attached to the rigid portion. Also included in the system is a ball received within the cup and in contact with the elastic portion and a femoral stem attached to the ball. The elastic portion is positioned to cause expansion and contraction of a space between the ball and the rigid portion of the cup so they are further apart from one another during periods of low mechanical loads.
Abstract:
A glenoid component can include a base plate (110). A glenosphere (112) can be configured to be mountable to the base plate. The glenosphere can be adapted to operate with a complementary humeral component (102). The base plate can include a removable taper member (302) on a side of the base plate facing the glenosphere. The taper member can be configured to mount the glenosphere to the base plate. The removable taper member allows revision of the glenoid component without removal of the components fixed to the bone.
Abstract:
A device for positioning within a body lumen, adjacent to the mouth of an aneurysm extending from the body lumen, for causing thrombosis of the aneurysm while maintaining substantially normal blood flow through a blood vessel, the device comprising: a single closed loop of elastic filament configurable between: (i) a first longitudinally-expanded, radially and laterally-contracted configuration for movement along a blood vessel and (ii) a second longitudinally-contracted, radially and laterally-expanded configuration for lodging within a blood vessel, the second configuration providing (a) a single flow-restricting face configured to cover the mouth of the aneurysm and obstruct blood flow to the aneurysm while permitting substantially normal blood flow through the blood vessel and (b) at least one leg for holding the single flow-restricting face adjacent the mouth of the aneurysm, the at least one leg configured so as to maintain substantially normal blood flow through the blood vessel.
Abstract:
An intra-vascular device (100) may include a skeleton (102) to hold a blood filter (104), an upper member (110) to fit into a branch artery of an aorta, and a pair of lower members (106, 108) whose distal ends are not connected to each other, such lower members to press against a wall of an ascending artery and to provide lift to the device so that a middle portion of the device is above a lateral plane of the device. The device may be positioned in a middle area of an aortic arch near but not covering an opening of the branch arteries of the aorta, and may filter or deflect emboli or other large objects from entering into the branch arteries.
