  • Patent number: 11752019
    Abstract: A medical device such as a stent or medical balloon is functionalised prior to coating with a bioactive material, specifically by carboxylic acidification of the contact surface or surfaces of the medical device. The preferred process involves washing a stent or other medical device in a washing solution which may be sodium hydroxide, soaking in a carboxylic acid solution, rinsing in water to remove excess carboxylic acid, allowing to dry before applying a bioactive agent layer. It has been found that washing after functionalisation removes excess carboxylic acid and enhances the retention of bioactive agent on the contact surface or surfaces of the medical device leading to a more uniform and consistent layer of bioactive agent.

    Abstract: The present embodiments provide apparatus and methods suitable for delivering a therapeutic agent to a target site. The apparatus generally comprises at least one container for holding a therapeutic agent, and a pressure source for facilitating delivery of the therapeutic agent. In one embodiment, the pressure source may be placed in selective fluid communication with a proximal region of the container and fluid from the pressure source may flow through at least a portion of the container to urge the therapeutic agent through container towards the target site. In an alternative embodiment, the container and the pressure source may be coupled to first and second inlet ports of a connecting member, respectively, such that the therapeutic agent flows through an outlet port of the connecting member and towards the target site.

  • Publication number: 20230277296
    Abstract: Examples of prostheses are provided having an internal branch. A tubular graft body of the prosthesis defines a main lumen extending between an inflow end and an outflow end of the graft body. A stent structure is coupled along the graft body. A trough is at least partially defined by a trough wall extending into the main lumen from a sidewall of the graft body. A side branch defines a branch lumen and extends from the trough within the main lumen towards one of the inflow or outflow ends of the graft body. A branch lumen facing surface of the trough wall is a continuous surface with an outer surface of the sidewall of the graft body. A boundary of the trough may be configured to provide a smooth transition surface between the trough and the sidewall.

  • Patent number: 11744985
    Abstract: A steerable catheter having a hub with a control feature includes a semi-rigid catheter with the hub attached at the proximal end. The distal end of the catheter includes a distal tip and a flexible portion adjacent the distal tip. The catheter includes a working channel, and further includes a channel through which a tension member or wire extends to the distal tip. Tension in the wire causes the distal tip to deflect and be steered. The hub includes a fixed member attached to the catheter, an inner member that moves axially relative to the fixed member, and an outer member that rotates relative to the inner member and the fixed member. Rotation of the outer member results in translation of the inner member, which is attached to the tension member and provides for controlled steering of the distal tip.
