Publication number: 20240299710Abstract: The present disclosure relates to guidewire devices with an outer tube and a core. The distal section of the core extends into and is surrounded by the outer tube. One or more centering mechanisms are also disposed within the outer tube and are arranged to fill a portion of the annular space between the core and the inner surface of the tube. The one or more centering mechanisms thereby assist in keeping the distal section of the core axially aligned within the tube, which enables effective control of the device and minimizes undesirable whip movements of the guidewire.Type: ApplicationFiled: May 10, 2024Publication date: September 12, 2024Inventors: Clark C. Davis, Edward J. Snyder, Todd H. Turnlund

Patent number: 12053595Abstract: The present disclosure relates to devices and methods for accessing a targeted vessel, such as a coronary artery, near the aortic root. A catheter device includes a proximal section, an intermediate section, and a distal section. The intermediate section includes a more proximal section (a proximal-intermediate section) and a more distal section (a distal-intermediate section). The proximal-intermediate section is microfabricated to enable preferred bending along a single plane. The distal-intermediate section is more rigid than the proximal-intermediate section and the distal section. In use, the proximal-intermediate section abuts against the aortic wall and bends to allow the distal-intermediate section to extend across the aortic root toward a targeted vessel on the opposite side of the aorta.Type: GrantFiled: December 29, 2021Date of Patent: August 6, 2024Assignee: Scientia Vascular, Inc.Inventors: Edward J. Snyder, John A. Lippert, Todd H. Turnlund, Clark C. Davis

Publication number: 20230082226Abstract: Disclosed are guidewire and catheter systems that can be used to facilitate desirable catheter axial response (e.g., pushability) over a guidewire for advancement through patient vasculature. Features of the guidewire and catheter systems enable the catheter to advance over the guidewire within the tortuous paths of a patient's vasculature in response to push forces that do not exceed 50 g.Type: ApplicationFiled: September 1, 2022Publication date: March 16, 2023Inventors: John A.

Patent number: 10835316Abstract: An emitter assembly can include a proximal shaft, a distal shaft, a shunt that connects the proximal shaft to the distal shaft, and a tip that is connected to a distal end of the distal shaft. An inner conductor can extend through the proximal shaft, the shunt, and the distal shaft and into the tip to provide microwave energy to the tip. An outer conductor can extend into the shunt. The shunt can therefore form an electrical connection between the outer conductor and a proximal ring of electrically conductive material formed on an exterior surface of the distal shaft. Distal shaft can be made of a thermally conductive but electrically insulated material to facilitate transfer of heat from the distal shaft to the proximal shaft.Type: GrantFiled: May 14, 2018Date of Patent: November 17, 2020Assignee: Endocare, Inc.Inventors: Chet M.

Patent number: 9078784Abstract: A flexible structural apparatus which may be used as a wound covering which extends above the wound such that the wound covering does not contact the wound and also protects the wound from contact. The apparatus provides a high degree of flexibility while retaining structural strength and resisting collapse, for example, so as to adequately protect the wound. Various embodiments include parallel beams and connections between beams that alternate in location along the beams to provide flexibility. Some embodiments may be used as springs and may have attachment features, such as holes, which may be located at the end beams, for example.Type: GrantFiled: February 5, 2010Date of Patent: July 14, 2015Assignee: THT CONSULTING, LLCInventors: Todd H.

Patent number: 8939916Abstract: Medical devices for navigation through anatomy, including guidewires, which may have a core wire, a slotted tubular member, or both. Embodiments may have coils, including non-circular cross-section edge-wound marker coils, extended coil tips, and soldered or glued mesial joint coils. Core wires may have a step, ridge, or taper at the joints to the tubular member, and may be flattened at the distal tip. Radiopaque material may be located inside the tubular member, and the distal tip may be heat treated to make it shapeable. Additional tubular members or coils may be used concentrically or in line and may enhance flexibility, provide radiopacity, reduce friction, or reduce material or manufacturing cost. Tubular members may be chamfered or tapered continuously or incrementally. Slots may be arranged in groups, such as groups of three, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.Type: GrantFiled: July 31, 2007Date of Patent: January 27, 2015Assignee: Precision Vascular Systems, Inc.Inventors: Stephen C.
