Patent number: 11752019Abstract: 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.Type: GrantFiled: November 29, 2018Date of Patent: September 12, 2023Assignee: Cook Medical Technologies LLCInventors: John Neilan, David Murray, James Butler

Patent number: 11744985Abstract: 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.Type: GrantFiled: November 4, 2020Date of Patent: September 5, 2023Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Jeffry Scott Melsheimer, Patrick James Zito
