A vascular filter device () has a support frame () and filter elements (). The filter elements () extend from the support frame towards filter element ends forming an on-axis apex () at which they are interconnected by a holder (). The filter elements () are biased such that if unconnected the filter element ends are located between the support frame and said central axis when the vascular filter device is unconstrained. The filter element unconnected positions are provided by the filter element shapes and the angles at which they extend from the support frame, and in one example this is achieved by laser cutting tubing and heat setting the material.

Vascular filter device

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

Vascular filter

Provided is a device for delivery into a body lumen having a longitudinally extending stem and a plurality of bristles extending generally radially outwardly from the stem. The device includes at least two different groups or types of bristles.

Embolization systems

A vascular filter device () has a support () for engaging the wall of a blood vessel. A filter has filter elements () having proximal segments () connected to the support () and distal segments at least temporarily restrained at a distal apex () by a holder when in a filtering closed position. At least one filter element () extends radially outwardly with respect to a device longitudinal axis when unconstrained. The filter element may extend in a curve with a concave portion facing radially outwardly in an unconstrained configuration.

Vascular filter system

A vascular filter system comprises a vascular filter (), a clamp device (), and a delivery catheter (). The filter () comprises filter elements (). When used without the clamp device (), the filter elements () move from a closed state to an open state upon elapse of a predetermined period of time. In the closed state the filter elements () capture thrombus passing through the inferior vena cava (). The delivery catheter () is employed to deliver the clamp device () to the filter () after the filter () has been deployed in the inferior vena cava (). The clamp device () engages with the filter elements () of the filter () to clamp the filter () in the closed state beyond elapse of the predetermined period of time. Because of the presence of the clamp device (), the filter elements () are no longer free to move from the closed state to the open state upon elapse of the predetermined period of time. In this manner the period of time in which the filter () captures thrombus is extended either temporarily or permanently.

A bristle device for delivery into a body lumen comprises a longitudinally extending stemand a plurality of bristles extending generally outwardly from the stem for anchoring the device in a body lumen. There may be at least two bristle segments and in some cases there are flexible sections between the segments. The flexible sections articulate to enable the device to pass through a catheter placed in a tortuous anatomy or to be deployed in a curved vessel, or across a bifurcation. In some cases at least some of the bristle segments are spaced-apart to accommodate bending of the bristles.

Embolisation systems

A vascular filter device () comprises a plurality of filter elements () which are movable from a capturing position to an open position upon elapse of a predetermined period of time. In the capturing position the filter elements () are configured to capture thrombus passing through the inferior vena cava. In the open position the filter elements () are configured to facilitate unrestricted blood flow. The filter elements () are biased towards the open position. The filter () comprises a holder member () to temporarily hold the filter elements () in the capturing position until elapse of the predetermined period of time. The holder member () comprises a biostable wire element () which extends through an opening () in each filter element (), and a biodegradable/bioabsorbable stop element (). Upon biodegrading/bioabsorbing of the stop element (), the filter elements () are free to move from the capturing position to the open position.

A bristle device () for delivery into a body lumen comprises a longitudinally extending stem and a plurality of bristles extending generally outwardly from the stem for anchoring the device in a body lumen. There may beat least two bristle segments () and there are flexible sections () between the segments (). The flexible sections () articulate to enable the device to pass through a catheter placed in a tortuous anatomy or to be deployed in a curved vessel, or across a bifurcation. In some cases at least some of the bristle segments () are spaced-apart to accommodate bending of the bristles.

A medical device suitable for location in a body lumen is movable between a first loaded configuration and a second loaded configuration. The device has an unloaded configuration which is intermediate the first loaded configuration and the second loaded configuration. The device can be a stent for deployment in a blood vessel.

Medical device suitable for location in a body lumen

A bristle device for delivery into a body lumen comprises a longitudinally extending stem 1 and a plurality of bristles extending generally outwardly from the stem for anchoring the device in a body lumen. There may be at least two bristle segments and in some cases there are flexible sections between the segments. The flexible sections articulate to enable the device to pass through a catheter placed in a tortuous anatomy or to be deployed in a curved vessel, or across a bifurcation. In some cases at least some of the bristle segments are spaced-apart to accommodate bending of the bristles.
