A blood pump includes an impeller having a plurality of foldable blades and a cannula having a proximal portion with a fixed diameter, and a distal portion with an expandable diameter. The impeller can reside in the expandable portion of the cannula. The cannula has a collapsed condition for percutaneous delivery to a desired location within the body, and an expanded condition in which the impeller can rotate to pump blood. A flexible drive shaft can extend through the cannula for rotationally driving the impeller within the patient's body.

A valve prosthesis is adapted to operate in conjunction with native heart valve leaflets. The prosthesis includes an annulus and a skirt extending from the annulus. The skirt may be configured to be positioned through a native heart valve annulus, and the skirt may be movable between an open configuration permitting blood flow through the skirt and a closed configuration blocking blood flow through the skirt in cooperation with opening and closing of the native heart valve leaflets.

Disclosed are cardiac shunts and method of delivery, and in particular, to a shunt to reduce elevated left atrial pressure (LAP). The methods include forming a puncture hole between the left atrium and the coronary sinus, widening the puncture hole, and placing an expandable shunt within the widened puncture hole. A first catheter having a side-extending needle may be used to form a puncture into the left atrium. A second catheter extends along a guidewire and an expandable shunt with distal and proximal flanges is expelled therefrom into the puncture. The shunt defines a blood flow passage therethrough that permits shunting of blood from the left atrium to the coronary sinus when the LAP is elevated. The shunt is desirable formed of a super-elastic material and manipulated with control rods. The shunt defines a tilted flow tube that facilitates collapse into the catheter.

A soft storage bin made from flexible material and having a bottom, two first sidewalls, two second sidewalls, and a top opening. A hard full-wall board is embedded in each of the two first sidewalls and at least one set of two hard half-wall boards is embedded in at least one of the second sidewalls. The two half-wall boards are separated from each other by a folding line. A hard bottom board is seated within the interior of the body of the drawer and is supported by the bottom. Each drawer can be collapsed by moving the bottom board away from the bottom to allow the second sidewalls to be folded inward. Preferably, two half-wall boards are embedded in each second sidewall. A full-wall pocket is provided each first sidewall to receive the full-wall board and each second sidewall is provided two half-wall pockets to receive each half-wall board.

A fluid supply assembly. The fluid supply assembly includes a disposable cup and lid, and a reusable shell and outer lid. A flexible, disposable cup, a reusable shell, and a method of preparing a fluid supply assembly for use with a fluid supply applicator are also described.

The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue grasping elements to apply a wound closing force to the tissue.

A device, method and system for causing a controlled collapse of cavities formed within liquid droplets wherein a pressurized jet comprising a liquid and nanoparticle material and possibly fuel produces droplets from the breakup of the jet stream. The liquid droplets are irradiated with energy to produce and expand cavities formed within the droplets by irradiation of the nanoparticles contained within the droplets. The droplets are collided with a target to collapse the cavities within the droplets. The irradiating and colliding are timed to enhance implosion energy resulting from the cavities' collapse. The implosion energy and the fuel in the cavity may be used to activate and sustain a fusion reaction.

An inferior vena cava filter (340) for use in the inferior vena cava (4) to capture thrombus (8) passing through the inferior vena cava (4) towards the heart and lungs to prevent pulmonary embolism comprises a proximal support hoop (302), a distal support hoop (312) and a plurality of support struts (303) extending between the proximal support hoop (302) and the distal support hoop (312). The filter (340) also comprises a plurality of capture arms (121) which are movable from a capturing configuration to an open configuration. The capture arms (121) are biased towards the open configuration. A biodegradable suture holds the capture arms (121) in the capturing configuration.

A hammock stand has a plurality of legs, support rods, and a cross brace that couples at least one leg to at least one of the support rods such that the hammock stand collapses in a single movement.

A debris-capturing apparatus for a cleaner device having an outflow port through which debris-laden liquid flows. The debris-capturing apparatus has an entry annulus and a debris cavity to receive flow of debris-laden liquid. A collapsible elongate back-flow restrictor, which is substantially erect in the flow direction during inflow, has an annular proximal-end portion secured about the entry annulus and a free-end portion within the debris cavity. The free-end portion has at least one discontinuity along the length thereof to relieve resistance to debris-laden fluid flow into the cavity and to facilitate collapse of the restrictor for back-flow restriction.
