Publication number: 20240423821Abstract: A stent graft delivery system includes a stent graft and a thermal stent graft cutter for shortening the stent graft to a desired length in vivo. The thermal stent graft cutter is coupled to at least one of a stent graft cover at a distal longitudinal end of a cover body thereof, and the inner lumen tip of an inner lumen. A safety system allows activation of the stent graft cutter only when the stent graft is suitably sandwiched between the inner lumen tip and the distal end of the stent graft cover to inhibit inadvertent activation of the cutter and provide for proper cutting of the stent graft.Type: ApplicationFiled: September 9, 2024Publication date: December 26, 2024Inventors: Gianfranco M. Pellegrini, Adam J. Shipley, Mark L. Stiger, Zachary E. Borglin

Publication number: 20240415496Abstract: A system includes an imaging system and a tracking system. The system generates a navigation space based on one or more tracking signals emitted by a transmission device. The system generates a virtual space including at least a portion of a calibration phantom based on one or more images generated by the imaging system. The system identifies a set of coordinates in the virtual space in response to an event in which at least a portion of the tracked device is detected in the one or more images. The system calibrates a first coordinate system associated with the virtual space with respect to a second coordinate system associated with the navigation space in response to the event. Calibrating the first coordinate system with respect to the second coordinate system is based on the set of coordinates and temporal information associated with the event.Type: ApplicationFiled: May 28, 2024Publication date: December 19, 2024Inventors: Osvaldo Andres Barrera, Joseph D.

Publication number: 20230233349Abstract: Methods, apparatuses, and systems are described for stent delivery and positioning for transluminal application. The system may include a stent that is disposed coaxially onto an inner tubular member. In some cases, the system may include an outer sheath disposed coaxially along at least a portion of the inner tubular member. The system may include a distal cutting element coupled with a distal end of the inner tubular member and an anchoring component disposed at a distal portion of the inner tubular member. The anchoring component may be configured to retain a distal portion of the stent in place along the inner tubular member as the outer sheath is retracted proximally to deploy the stent, wherein upon retraction of the outer sheath, the stent releases from the anchoring component and expands into a deployed configuration within the body lumen.Type: ApplicationFiled: January 21, 2022Publication date: July 27, 2023Inventors: Siddhi K.

Publication number: 20230157762Abstract: Disclosed herein are techniques for implementing an intelligent assistance (“IA”) or extended intelligence (“EI”) ecosystem for soft tissue luminal applications. In various embodiments, a computing system analyzes first layer input data (indicating movement, position, and/or relative distance for a person(s) and object(s) in a room) and second layer input data. The second layer input data includes sensor and/or imaging data of a patient. Based on the analysis, the computing system generates one or more recommendations for guiding a medical professional in navigating a surgical device(s) with respect to one or more soft tissue luminal portions of the patient. The recommendation(s) include at least one mapped guide toward, in, and/or around the one or more soft tissue luminal portions. The mapped guide can include data corresponding to at least three dimensions, e.g., a 3D image/video. The computing system can present the recommendation(s) as image-based output, using a user experience device.Type: ApplicationFiled: September 29, 2022Publication date: May 25, 2023Inventors: Peter N.

Patent number: 9358370Abstract: Embodiments hereof relate to a guidewire formed from an elongated shaft, at least a portion of the shaft having an outer layer, a plurality of channels formed through the outer layer, and an inner core. The outer layer is formed from a material non susceptible to erosion by an erosion agent and the inner core is formed from a radiopaque material susceptible to erosion by the erosion agent. When exposed to the erosion agent, core material adjacent to the channels is removed to form a pattern of integral radiopaque segments or markers with a plurality of voids therebetween. By controlling the location of channels and the rate of erosion of the core material, the pattern of integral radiopaque segments and voids allow for in situ measurement when viewed under fluoroscopy.Type: GrantFiled: March 12, 2012Date of Patent: June 7, 2016Assignee: Medtronic Vascular, Inc.Inventors: Mark L.

Publication number: 20100268315Abstract: A method of deploying a stent graft includes radially constraining proximal apexes of a proximal anchor stent ring of the stent-graft in a space between merlons of a castellated sleeve of a tip and a spindle having spindle pins, the proximal apexes extending around the spindle pins. A graft material of the stent-graft is radially constrained in a primary sheath, a proximal end of the graft material being attached to distal apexes of the proximal anchor stent ring. The proximal anchor stent ring further includes struts extending between the proximal apexes and the distal apexes. The primary sheath is retracted to allow the proximal end of the graft material and the distal apexes of the proximal anchor stent ring to pivot out beyond the confines of the sleeve to a large angle as the proximal end radially expands. The struts then extend through embrasures of the castellated sleeve. The tip is advanced to deploy the proximal apexes.Type: ApplicationFiled: April 17, 2009Publication date: October 21, 2010Applicant: Medtronic Vascular, Inc.Inventors: Brian Glynn, Mark L. Stiger

Patent number: 6746392Abstract: An over-the-wire catheter provides substantially shadow-free delivery of radiation to a body lumen by having a treatment region wherein a guidewire tube and a radiation source tube form a parallel double helix configuration. When a radiation source is inserted into the radiation source tube and a guidewire is present in the guidewire tube, no portion of the treatment site will be obscured from all radiation emitted by the radiation source because, within the treatment region, the guidewire and the radiation source are not in a conventional, axially parallel configuration. Optionally, a balloon may be mounted about or adjacent the treatment region of the catheter, the balloon providing centering and/or dilatation functions.Type: GrantFiled: June 20, 2001Date of Patent: June 8, 2004Assignee: Medtronic AVE, Inc.Inventors: Mark L. Stiger, Sam Ciamacco, Jr.

Patent number: 6679860Abstract: The invention is an intraluminal therapy catheter having a least two treatment members disposed near the distal end of the catheter, the members being independently inflatable to perform angioplasty and/or fluid-sourced brachytherapy. A first treatment member is helically mounted about the shaft of the catheter, and forms a helical perfusion channel when inflated into contact with the vessel being treated. In a first embodiment of the invention, the second treatment member is also helically mounted about the catheter shaft and capable of forming a helical perfusion channel when inflated into contact with the vessel. The first and second treatment members are intertwined to form a double helix configuration wherein each member is capable of being inflated to generally fill the helical perfusion channel created by simultaneous inflation of the other member.Type: GrantFiled: June 19, 2001Date of Patent: January 20, 2004Assignee: Medtronic Ave, Inc.Inventor: Mark L.
