Patent number: 8227016Abstract: The present invention provides a method of applying a drug-polymer coating on a stent. A stent framework is dipped into a first polymeric solution including a first polymer, a first therapeutic agent, and a first solvent. The polymeric solution is dried and the first polymer is cured to form a thin drug-polymer layer on the stent framework. The steps of dipping the stent framework into the first polymeric solution, drying the first polymeric solution, and curing the first polymer are repeated until a target drug-polymer coating thickness is disposed on the stent framework. A drug-polymer coated stent including a stent framework and a laminated drug-polymer coated stent, a system for treating a vascular condition, and a method of treating a vascular condition are also disclosed.Type: GrantFiled: May 18, 2010Date of Patent: July 24, 2012Assignee: Medtronic Vascular, Inc.Inventors: Ronan Thornton, Finbar Dolan

Patent number: 7955640Abstract: The present invention provides a method of applying a drug-polymer coating on a stent. A stent framework is dipped into a first polymeric solution including a first polymer, a first therapeutic agent, and a first solvent. The polymeric solution is dried to form a thin drug-polymer layer on the stent framework. The stent framework with the thin drug-polymer layer, which is insoluble in the second polymeric solution, is dipped into a second polymeric solution including a second polymer and a second solvent and is dried to form a thin barrier layer on the thin drug-polymer layer. The steps of dipping the stent framework into the first polymeric solution, drying the first polymeric solution, dipping the stent framework into the second polymeric solution, and drying the second polymeric solution are repeated until a target drug-polymer coating thickness is disposed on the stent framework.Type: GrantFiled: November 26, 2007Date of Patent: June 7, 2011Assignee: Medtronic Vascular, Inc.Inventors: Ronan Thornton, Finbar Dolan

Publication number: 20100130852Abstract: A catheter system for positioning of a medical instrument that includes a first elongate member having a first lumen. The catheter system also includes a second elongate member that includes a second lumen that receives the medical instrument. The second elongate member is coupled directly to the first elongate member, and the second elongate member is operable to be at least partially segmented generally along a second longitudinal axis thereof to allow movement of the medical instrument outside the second lumen. The second elongate member is selectively collapsible and expandable to change a size of the second lumen.Type: ApplicationFiled: November 21, 2008Publication date: May 27, 2010Applicant: Medtronic, Inc.Inventors: Michael R. Neidert, Niall Duffy, Neil L. Purcell, Ronan Thornton

Publication number: 20100082000Abstract: A catheter system for positioning of a medical instrument within a body. The catheter system includes a hub defining a main lumen therethrough for passage of the medical instrument. The catheter system also includes an elongate tubular member defining a lumen therethrough. The lumen of the elongate tubular member is in communication with the main lumen of the hub for further passage of the medical instrument. The elongate tubular member defines a first portion and a second portion. The catheter system also includes a reinforcement member that is fixedly coupled to and reinforces the elongate tubular member, the reinforcement member includes a first part, a second part, and a partition defined between the first and second parts. The first and second parts are adapted to selectively move away from each other along the partition to thereby move the first and second portions away from each other and to uncover the medical instrument.Type: ApplicationFiled: September 30, 2008Publication date: April 1, 2010Applicant: Medtronic, Inc.Inventors: Jordon Honeck, Ronan Thornton, Michael R.

Patent number: 7108682Abstract: The present invention protects a distal portion of a catheter during shipment and storage. The device holds the distal portion suspended such that it does not contact the device. The suspended portion is protected from damage resulting from abrasion. When the suspended portion includes a therapeutic coating, the coating is protected from the risk of impaired performance resulting from a therapeutic agent migrating out of the coating and into the packaging material or components of the packaging material migrating into the therapeutic coating, both of which can occur if a therapeutic coating remains in contact with another material for an extended period of time.Type: GrantFiled: January 24, 2003Date of Patent: September 19, 2006Assignee: Medtronic Vascular, Inc.Inventors: Niall Duffy, Ronan Thornton

Patent number: 7060090Abstract: The present invention relates to a stent manufactured from a thin-walled tube of surgical implant quality. The stent comprises a plurality of main circumferential rings, a plurality of longitudinal links and a plurality of intermediate circumferential rings. The main circumferential rings are longitudinally spaced apart along a longitudinal axis. Circumferential gaps are formed between adjacent main circumferential rings. The longitudinal links span the gaps and are attached to adjacent main circumferential rings. The intermediate circumferential rings fill in the circumferential gaps and are attached to the longitudinal links. The present invention thereby provides a stent with adequate radial strength to properly deploy, adequate scaffolding affect to properly support vessel walls and increased longitudinal flexibility to easily maneuver through tortuous vessels.Type: GrantFiled: October 15, 2003Date of Patent: June 13, 2006Assignee: Medtronic Vascular, Inc.Inventor: Ronan Thornton

Publication number: 20050256532Abstract: The present invention provides a defect patch device and method that patches a defect in the heart or other cardiovascular tissue. One aspect provides a PFO closure device and method that patches a PFO in the right atrium without the device extending through the PFO into the left atrium. The patch device includes a patch and a heart tissue engaging member for attaching the device over the defect. A deployment device and method includes a device positioner to advance the device out of a catheter and to position the device over the defect to attach the device to the tissue around the defect. The positioner may include a device expander or opener that opens the device for deployment.Type: ApplicationFiled: May 12, 2004Publication date: November 17, 2005Inventors: Asha Nayak, Sean Saint, Terry Guinan, Ronan Thornton, Patrick Hanley, Hilda Mulvihill
