摘要： There is disclosed a tri-leaflet valve (100) in which the leaflets (102) extend for substantially the entire length of the valve (100). The valve (100) is provide with a waist (106). An element (16) inserted in the tri-leaflet valve (100) can be sealed by closure of the valve (100), for example by pressurization or twisting. The seal is more effective then prior art seals.

摘要： The haemostatic valve assembly (10) includes a housing (14) with a chamber (16) therewithin. A flexible valve element (26) is located in the chamber (16) and supported by the housing (14). A source (28) of pressurized fluid can be fed into the chamber (16) through a port (18) in the housing (14). A catheter, dilator, pusher or other elongate insert fed through the haemostatic valve assembly (10) can be sealed by the application of fluid pressure into the chamber (16), which causes the sides of the valve element (26) to press against the insert (24) thereby to provide an effective seal.

摘要： The present invention provides a removable vena cava filter for capturing thrombi in a blood vessel. The filter (10) comprises a plurality of primary struts (12) having first ends attached together along a longitudinal axis. Each primary strut has an arcuate segment extending from the first end to an anchoring hook (26). The primary struts are configured to move between an expanded state for engaging the anchoring hooks with the blood vessel and a collapsed state for filter retrieval or delivery. Each primary strut is configured to cross another primary strut along the longitudinal axis in the collapsed state such that the arcuate segments occupy a first diameter (D1) greater than a second diameter (D2) occupied by the anchoring hooks in the collapsed state for filter retrieval or delivery.

摘要： The present invention provides a removable vena cava filter (10) for capturing thrombi in a blood vessel. The filter comprises a plurality of primary struts (12) having first ends attached together along a longitudinal axis. Each primary strut includes an arcuate segment having a first tensile strength. The arcuate segment extends from the first end to an anchoring hook (26). The anchoring hook is integral with the arcuate segment and having the first thickness and first tensile strength. The filter further comprises a plurality of secondary struts (30) freely spaced between the primary struts and having connected ends attached together along the longitudinal axis. Each secondary strut freely extends from the connected end to a free end avoiding contact with other secondary struts and primary struts. Each secondary strut has a second tensile strength.

摘要： A removable filter (10) having a collapsed state and an expanded state for capturing thrombi in a blood vessel is disclosed. The filter comprises a plurality of primary struts (12) and a plurality of secondary struts. Each primary strut in the expanded state extends from a primary strut first end to an anchoring hook (26). Each primary strut extends arcuately along a longitudinal axis and linearly radially. The plurality of primary strut first ends are attached together along the longitudinal axis (x). Each secondary strut in the expanded state extends from a secondary strut first end to a free end. Each secondary strut extends arcuately along the longitudinal axis and linearly radially. The plurality of secondary struts are attached together along the longitudinal axis. The plurality of secondary struts centralize the filter in the expanded state in the blood vessel.

摘要： Endovascular filter (10) including a plurality of struts (14) with distal ends (18) adapted to anchor the filter to the vessel wall after deployment, such as by having barbs (20), the filter being adapted to be retrieved if 5 desired. Strut distal ends (18) are coated with an antiproliferative agent (40) that inhibits the ingrowth of tissue around the filter, thereby permitting the filter to be retrieved and removed atraumatically after a prolonged period of time, thus extending the useful life of the retrievable filter. Optionally, the proximal end (22) of the filter may also be so coated, or the entire filter.

摘要： The present invention involves a removable filter (10) for capturing thrombi in a blood vessel. The filter comprises a plurality of struts (12) having first ends attached together along a longitudinal axis (X) of the filter. Each strut has a body member (15) extending from the first end along the longitudinal axis to an anchoring hook (26) defining a strut axis (S). Each strut is configured to move along a strut path (P) relative to the longitudinal axis between an expanded state for engaging with the blood vessel and a collapsed state for filter delivery or retrieval. Each anchoring hook has an angle of up to about 90 degrees relative to the strut axis.
