Publication number: 20220143399Abstract: The present technology is generally directed to medical implants, such as stimulation assemblies for stimulating the septal wall of the heart of a human patent, and associated methods. In some embodiments, a stimulation assembly includes a body, circuitry positioned at least partially within the body, an electrode, and an anchor coupled to the body. The anchor can be secured to the septal wall such that the body is positioned within the left ventricle of the heart and the electrode engages tissue of the septal wall. The circuitry can be configured to receive acoustic energy and to convert the acoustic energy to electrical energy, and the electrode can deliver the electrical energy to the tissue of the septal wall to stimulate the tissue.Type: ApplicationFiled: November 9, 2021Publication date: May 12, 2022Inventors: Parker Willis, Timothy A. Fayram, Allan Will, Richard Riley, John P. Sam

Patent number: 8574282Abstract: Blood vessels and other body lumens are expanded using an evertible braided prosthesis. The braided prosthesis is delivered to the blood vessel in a radially collapsed configuration. A leading edge of the braided prosthesis is then everted so that it expands as it is advanced through the blood vessel. Optionally, the prosthesis can be provided with a biologically active substance in order to inhibit hyperplasia or have other desired biological effects.Type: GrantFiled: April 1, 2011Date of Patent: November 5, 2013Assignee: J.W. Medical Systems Ltd.Inventors: Bernard Andreas, Ronald French, Mark E. Deem, Hanson S. Gifford, III, Allan Will

Patent number: 8070789Abstract: Apparatus for delivering stents to body lumens include one or more tubular prostheses carried at the distal end of a catheter shaft, a sheath slidably disposed over the prostheses, and a guidewire tube extending from within the sheath to the exterior of the sheath through an exit port in a sidewall thereof. A guidewire extends slidably through the guidewire tube. The sheath can be moved relative to the catheter shaft and the guidewire tube to expose the prostheses for deployment. Methods of delivering stents are also provided.Type: GrantFiled: March 28, 2008Date of Patent: December 6, 2011Assignee: Xtent, Inc.Inventors: Allan Will, Bernard Andreas, Sunmi Chew

Patent number: 8016870Abstract: Blood vessels and other body lumens are stented using multiple, discrete stent structures, or continuous coiled or mesh stent structures. Stent structures may be a balloon expandable or self-expanding and are delivered by a delivery catheter which is repositioned to spaced-apart delivery sites. By coating the stents with particular biologically active substances, hyperplasia within and between the implanted stents can be inhibited. An exemplary delivery catheter comprises a catheter body having a deployment mechanism for deploying one or more stents of selectable length into the vessel.Type: GrantFiled: November 12, 2007Date of Patent: September 13, 2011Assignee: Xtent, Inc.Inventors: Sunmi Chew, Bernard Andreas, Hanson S.

By coating the stents with particular biologically active substances, hyperplasia within and between the implanted stents can be inhibited. An exemplary delivery catheter comprises a catheter body having both a pusher rod for advancing the stents relative to a sheath and a reciprocatable delivery catheter for implanting the stents.Type: GrantFiled: June 10, 2009Date of Patent: September 13, 2011Assignee: Xtent, Inc.Inventors: Sunmi Chew, Bernard Andreas, Hanson S.

Publication number: 20070270936Abstract: Methods and apparatus for delivering prostheses to body lumens, such as stents and grafts to blood vessels, utilize a delivery device which carries one or more linearized elements. The linearized elements assume non-linear configurations, particularly helical configurations, when advanced and released from the delivery device. By selectively controlling the length and/or number of elements delivered from the delivery device, extended and disseminated disease within the body lumens may be effectively treated.Type: ApplicationFiled: August 8, 2007Publication date: November 22, 2007Applicant: Xtent, Inc.Inventors: Bernard Andreas, Ron French, Allan Will
