Abstract: A clot retrieval device (9501) for removing occlusive clot from a blood vessel comprises an inner elongate body (9503) and an outer elongate body (9504) at least partially overlying the inner elongate body (9503). The device also comprises an elongate member or shaft (9502) having a proximal end which extends exterior of a patient so that a user can retrieve the stent-basket device and captured clot by retracting the shaft (9502). The outer elongate body (9504) and the inner elongate body (9503) are connected to the distal end of the shaft (9502) and are expandable relative to the shaft (9502) from a collapsed delivery configuration to an expanded deployed configuration. The outer elongate body (9504) is expandable relative to the inner elongate body (9503) to a radial extent which is greater than the radial extent of the inner body (9503) in the deployed configuration.

Abstract: A device including a processor which automatically allocates and transfers funds in a sweep account between a primary on-balance demand account and one or more off-balance accounts in a manner which assists the bank in maintaining an optimal liquidity profile and capital structure. The device is adapted to prepare and analyze current data pertaining to the liquidity profile and capital structure of a bank and compare this data to predetermined reference values stored in data storage means of the device. The device has an allocation unit which utilizes an algorithm in order to allocate an amount of funds to transfer between an on-balance account and one or more off-balance accounts which will provide an optimal liquidity profile and capital structure for the bank.

Abstract: A catheter system 1 has an internal reception space for an embolic protection filter 10 to enable the filter 10 to be transported through a vasculature 20 and a treatment means such as a stent 15 to facilitate treatment. The catheter system may be used for retrieval of a filter 10 and stenting of a lesion with a stent 15. The procedure may also involve post dilatation using an on-board balloon 16.

Abstract: A check valve in particular for medical applications has a first hose connecting casing and a second hose connecting casing and a membrane disk configured between the two hose connecting casings. The membrane disk is made of a resilient material and cooperates with an annular valve seat. The membrane disk is fitted radially outside the valve's seat with apertures leading to a discharge space. The wall of the second hose connecting casing is opposite the apertures and fitted with a surface curved away from the membrane toward the discharge channel. The discharge channel is fitted with an intake mouth in the wall, and conically tapers within a transition segment toward the intake mouth. Recesses communicating with the discharge space are fitted into the transition segment and are dimensioned in a way to substantially compensate the different flow cross-sections between the intake mouth and the discharge channel.

Abstract: An embolic protection filter for deployment in a vasculature, the filter having an inlet end and an outlet end, the inlet end having one or more inlet openings sized to allow blood and embolic material enter the filter, and the outlet end of the filter having a plurality of outlet openings sized to allow through passage of blood but to retain undesired embolic material within the filter. The filter is movable between a collapsed configuration for movement through a vasculature, and an outwardly extended configuration for deployment in a vasculature. The filter at least in the collapsed configuration was a guidewire lumen defined at least partially therethrough for passing the filter over a guidewire. The guidewire lumen is defined by a lumen-defining member which is spaced proximally of the distal end of the filter.

Alternatively, the device includes a partially cylindrical member, a handle; and at least one blade.

Abstract: A retrieval catheter 1 for retrieval of an embolic protection filter from a vasculature. The catheter 1 comprises a proximal hypotube 3, a radially offset distal shaft 4 and a centering shank 9. A guidewire lumen 13 is provided through the shank 9 in communication with a larger guidewire lumen 7 through the shaft 4 for a continuous guidewire passageway to accommodate passage of a guidewire 21 through the shank 9, the shaft 4 and out through a proximal guidewire opening 6 to facilitate rapid exchange of the catheter 1 over a guidewire 21. The shank 9 is movable between an introduction configuration in which the shank 9 protrudes distally from the shaft 4 to centre the catheter 1 during advancement through a vasculature, and a retrieval configuration in which the shank 9 is located within the guidewire lumen 7 to facilitate retrieval of an embolic protection filter into the shaft 4.

Abstract: A delivery catheter 1 for rapid exchange delivery of a stent 7 through a vasculature over a guidewire 10, and for rapid exchange deployment of the stent 7 at a desired site in the vasculature. The catheter 1 comprises a hypotube 2, a distal sheath 4 which defines an internal reception space for the stent 7, and a push wire 3. The catheter body 2 is fixedly attached to the sheath 4 by means of a junction piece 9. At the distal end of the wire 3, the catheter 1 comprises a tubular inner core 5 and a coiled spring 6 which acts as an abutment means for engagement with the stent 7 in the reception space upon retraction of the sheath 4 to facilitate deployment of the stent 7. The guidewire 10 passes proximally from the inner core 5, through the junction piece 9, and out of the junction piece 9 through a proximal guidewire opening 11.

Abstract: A retrieval catheter 1 comprises a distal tubular sheath 2 with a reception space 5 into which an embolic protection filter 10 may be retrieved. An elongate connector 10 extends proximally from the sheath 2 to allow a clinician to control movement of the sheath 12. The sheath 2 is backloaded over a procedural catheter such as a balloon catheter 20, for example for post dilatation of a stent 55. The procedure is more efficient and procedure time is reduced because a catheter system is provided which allows a procedural step to be carried out and a filter 50 to be retrieved.

Abstract: In a method for filtering embolic material, a guide catheter (5) is advanced through a vasculature. A delivery catheter (4), a guidewire (2) and a collapsed filter are advanced together through the guide catheter (5) to a point distally of the distal end of the guide catheter (5). The guidewire (2) is then advanced across the lesion. During this advancement of the guidewire (2), the delivery catheter (4) and the collapsed filter remain substantially stationary. When the guidewire (2) has crossed the lesion, the delivery catheter (4) and the collapsed filter are then advanced across the lesion until the collapsed filter is distal of the lesion. The delivery catheter (4) is then withdrawn to facilitate deployment of the filter at the location distal of the lesion to ensure that any embolic material released during performance of an interventional procedure at the lesion will be captured and safely retained within the filter.
