  • Patent number: 10286190
    Abstract: The technical disclosure relates to catheters useful for engaging a vessel from within a lumen defined by the vessel. A catheter includes an elongate shaft, an inflatable balloon disposed on the distal end of the elongate shaft, a guide disposed on the external surface of the balloon, and an engaging member having a distal end releasably secured by the guide such that the guide maintains the engaging member distal end adjacent the outer surface of the balloon when the balloon is in an uninflated configuration but releases the engaging member distal end as the balloon moves from an uninflated configuration to an inflated configuration. The technical disclosure also relates to methods of using a catheter.

  • Publication number: 20180021122
    Abstract: An implantable medical device such as a filter includes a plurality of struts arranged in a generally conical form with each strut having a first end, a second end, and an operative length between the first and second ends. Each strut is able to flex along its operative length and includes a strut skeleton having a first flexural modulus and a reinforcement element extending along the operative length and attached to the strut skeleton. The reinforcement element and the strut skeleton together have a second flexural modulus greater than the first flexural modulus. One of the reinforcement element and the strut skeleton varies in one of amount and composition continuously along the operative length such that the second flexural modulus varies in a continuous manner along the operative length. The reinforcement element is biodegradable thereby changing the flexural modulus from the second flexural modulus to the first flexural modulus.

  • Publication number: 20170128185
    Abstract: A removable vena cava filter configured for reduced trauma and enhanced visualization of anchoring hook placement relative to the vessel wall is disclosed. The filter includes a plurality of struts, each having an anchoring hook and a stop member proximate the anchoring hook. The stop members are configured to engage the vessel wall to prevent excessive penetration of the anchoring hooks into the vessel wall and to aid in the identification of anchoring hook placement relative to the vessel wall.

  • Patent number: 8858504
    Abstract: 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 resilient element (21), for example of foam, is located in the chamber (16) and applies a constant closing force on the valve element (26). The valve (10) can be opened by aspirating fluid held within the chamber (16), for example by means of a pump or syringe, thereby to create a vacuum therein which compresses the resilient element (21). Removal of the vacuum allows the resilient element (21) to expand again and to close the valve (10).

  • Patent number: 8828044
    Abstract: A thrombus retrieval device (10) includes a flexible catheter (12), a retrieval wire (26) fixed to the distal end (14) of the catheter (12) and which extends out of the catheter (12) at first and second apertures in the wall of the catheter (12). A trap element (28) typically made of a porous fabric material, is attached to the catheter (12) from the distal end (14) across the location of the apertures. The trigger wire (26) can be pulled in a proximal direction, which causes the catheter (12) to twist so as to form a loop. The trap element (28), attached to the catheter at location in which it loops, forms a net for trapping thrombi or other obstructions within a patient's lumen.

  • Patent number: 8579913
    Abstract: A driver assembly (50) for an introducer assembly (10) for the deployment of an implantable medical device (16) includes a sprung element (52) coupled to a yoke (56). The yoke (56) is coupled to a gripper element (58). The yoke (56) is coupled to a first handle unit (30) of the introducer (10). The sprung element (52) is coupled to a proximal handle unit (32). A brake element (66) acts to prevent operation of the sprung element (52) when no manual force is being applied to attract a sheath (24) and the assembly (10). When manual retraction force is applied to the assembly (50) the gripper element (58) the brake element (66) releases a sprung element (52) so that the lighter can apply a force assistance to assist in the retraction of the sheath (24) and thereby to assist in the deployment of a medical device.

  • Publication number: 20130204349
    Abstract: A stent assembly (10) is formed with a plurality of stent rings (12) which have sections (16, 18, 24) which are of a non-biodegradable material and struts and tie bars (20, 14) which are at least partially biodegradable. The stent ring (12) thus partially biodegrades in a patient over time. The structure is such that the apices (16, 18, 24) of the stent ring (12) are of a non-biodegradable material and thus able to behave as a conventional non-biodegradable stent, that is with the same flexibility and expansion force consistent with such stent rings. Parts (34, 44) of the stent ring (12) will degrade in time, thereby reducing the restoring force produced by the stent ring (12) and reducing the amount of foreign material retained within a patient's body. In one embodiment, the stent ring (12) will separate into individual components after a period.
