Publication number: 20220361945Abstract: Systems, devices and methods for percutaneously modifying leaflets within the heart, thereby facilitating further repair or replacement. In some embodiments, the leaflets are cut. In other embodiments, the leaflets are removed either in part or in whole. The modifications to the leaflets may be made in conjunction with a prosthetic valve or independently.Type: ApplicationFiled: November 9, 2020Publication date: November 17, 2022Applicant: AMX Technologies, LLCInventors: Paul Sorajja, Daniel Coyle, Richard Farrell, John Matthew Swoyer

Patent number: 8180461Abstract: Methods and apparatus for implanting a stimulation lead in a patient's sacrum to deliver neurostimulation therapy that can reduce patient surgical complications, reduce patient recovery time, and reduce healthcare costs. A surgical instrumentation kit for minimally invasive implantation of a sacral stimulation lead through a foramen of the sacrum in a patient to electrically stimulate a sacral nerve comprises a needle and a dilator and optionally includes a guide wire. The needle is adapted to be inserted posterior to the sacrum through an entry point and guided into a foramen along an insertion path to a desired location. In one variation, a guide wire is inserted through a needle lumen, and the needle is withdrawn. The insertion path is dilated with a dilator inserted over the needle or over the guide wire to a diameter sufficient for inserting a stimulation lead, and the needle or guide wire is removed from the insertion path.Type: GrantFiled: January 25, 2005Date of Patent: May 15, 2012Assignee: Medtronics, Inc.Inventors: George Mamo, Michele Spinelli, John Matthew Swoyer, Martin Theodore Gerber, Keith Richard Carlton

Publication number: 20110270269Abstract: An implantable medical electrical lead comprises a lead body extending between a distal end and a proximal end, and the distal end having at least one electrode of an electrode array extending longitudinally from the distal end toward the proximal end. The lead body at its proximal end may be coupled to a pulse generator, additional intermediate wiring, or other stimulation device. A fixation mechanism is formed on or integrally with the lead body proximal to the electrode array that is adapted to be implanted in and engage subcutaneous tissue, particularly muscle tissue, to inhibit axial movement of the lead body and dislodgement of the stimulation electrodes. The fixation mechanism comprises a plurality of tine elements arrayed in a tine element array along a segment of the lead.Type: ApplicationFiled: July 14, 2011Publication date: November 3, 2011Inventors: John Matthew Swoyer, Keith Carlton, Martin T. Gerber, George J. Mamo, Michele Spinelli, Steven David Hartle

Patent number: 6901287Abstract: An implantable therapy delivery system has a therapy delivery element that is inserted or implanted into a human body and anchored or fixed to tissue to delivery a therapy to a patient. In one embodiment an implantable neurostimulator uses an electrical stimulation lead to delivery a therapy such as sacral nerve stimulation, peripheral nerve stimulation, and the like. In another embodiment the implantable therapeutic substance delivery device, also known as a drug pump, is connected to a catheter to deliver a therapy to treat conditions such as spasticity, cancer, pain, and the like. The therapy delivery element is anchored to tissue using an adjustable anchor having a therapy grip element, at least two extension elements connected to the therapy grip element, and a tissue fixation element connected to the extension elements.Type: GrantFiled: April 26, 2001Date of Patent: May 31, 2005Assignee: Medtronic, Inc.Inventors: Scott J. Davis, Keith Richard Carlton, Martin Theodore Gerber, Thomas Delmar Schmelzer, John Matthew Swoyer, Carole Anne Tronnes
