Patent number: 10349971Abstract: This disclosure is directed to systems and methods for providing a guiding device having a dilatable, drilling tip. The tip is formed by wound helical members such that resistance to rotation in an unwinding direction dilates the tip. The helical members are configured so that the dilatable tip increases in stiffness when the helical members are tensioned by a resistance to rotation in the winding direction. In some embodiments, application of relative force between coaxial inner and outer tubular members is used to control the dilation, stiffness and drilling of the guiding member.Type: GrantFiled: August 3, 2015Date of Patent: July 16, 2019Assignee: CARDINAL HEALTH SWITZERLAND 515 GMBhInventor: Matthew Wilkinson

Patent number: 10349973Abstract: A treatment of a medical difficulty associated with the formation or presence of a blood clot in a blood vessel, commonly known as “thrombectomy.” Said treatment may be achieved by introducing and positioning through a single lumen a device capable of macerating, irrigating and aspirating as well as supporting structures proximal to the distal end of said device. Said device is introduced via a blood vessel, and deployed at a treatment site. The macerator is then operated to dislocate thrombus, clot, or other occlusive materials at the target site, the irrigating element is then operated to continue to dislocate thrombus, clot, or other occlusive materials at the target site, and the aspirating element is used to collect and remove the disruptive materials from the target site.Type: GrantFiled: May 18, 2018Date of Patent: July 16, 2019Inventor: Daniel Ezra Walzman

Patent number: 10349974Abstract: Described herein are atherectomy catheters, systems and methods that include longitudinally displaceable drive shafts that drive actuation of one or more cutters at the distal end of the catheter. The catheters described herein may include one or more imaging sensors for imaging before, during or after cutting tissue. In some variations the imaging sensor may be rotated around the perimeter of the catheter independently of the rotation of the cutter. Also describe herein are imaging catheters that may be used without cutters.Type: GrantFiled: May 23, 2016Date of Patent: July 16, 2019Inventors: Himanshu N. Patel, John B. Simpson, Charles W.

Patent number: 10349977Abstract: A catheter assembly includes a resector balloon catheter and a hub coupled to the proximal portion of the catheter. The hub includes an inflation port that supplies fluid to a first lumen of the catheter to inflate a resector balloon. The hub further includes a delivery port for delivering an agent, such as drugs, to a second lumen of the catheter for delivery to the distal end of the catheter. The hub also includes an aperture for inserting a device, such as an imaging device, into the second lumen of the catheter. In some embodiments, the catheter includes a third lumen, and the hub includes an additional port in fluid communication with the third lumen.Type: GrantFiled: March 15, 2013Date of Patent: July 16, 2019Assignee: Sanovas Intellectual Property, LLCInventors: Erhan H. Gunday, Lawrence J. Gerrans, Alex Hsia, Devin J S Scheifele, Jessie Tung

Patent number: 10349978Abstract: This disclosure provides various embodiments of implant tools and implant techniques utilizing those tools. In one embodiment, an implant tool comprises a handle and a shaft. The shaft includes a proximal end adjacent the handle, a distal end, an open channel that extends from near the proximal end to the distal end, and at least one lumen that extends from a proximal end of the shaft to a location near the distal end of the shaft. The implant tool may also include a coupler configured to connect to a fluid delivery device. In one example, the fluid delivery device may be a syringe. In some instances, the handle of the implant tool may include a compartment or a recess configured to receive the fluid delivery device.Type: GrantFiled: December 18, 2015Date of Patent: July 16, 2019Assignee: Medtronic, Inc.Inventors: Kevin R. Seifert, Nathan L. Olson, Becky L. Dolan

Patent number: 10349979Abstract: A medical instrument and procedure for removing a food mass lodged in the esophagus of a patient. First, the food mass is magnetized. Thereafter, a medical instrument that includes a magnetic retriever is inserted into an endoscope, for example, into the esophagus. The magnetic retriever includes a magnet that applies a drawing force to the lodged magnetized food mass, causing the magnetized food mass to become dislodged. Once dislodged, the food mass is retrieved and removed from the esophagus.Type: GrantFiled: August 8, 2017Date of Patent: July 16, 2019Inventor: Alma F. Jenkins
