Publication number: 20240058603Abstract: A temporary pacing lead has an atraumatic curled distal region with multiple cathodes and distal pressure measurement to allow positioning and repositioning within the heart chamber without fluoroscopic or echo guidance. The curled distal region provides definite contact with two opposing walls of the ventricular chamber to ensure electrical signal capture without trauma to the endocardial surface. A stylet located in the pacing lead lumen assists in introducing, placing, and removing the pacing lead from the heart. The flexible distal region provides safe removal of the temporary lead following completion of use.Type: ApplicationFiled: April 4, 2023Publication date: February 22, 2024Applicant: Nextern Innovation, LLCInventors: Wesley Robert Pedersen, Paul Sorajja

Patent number: 11878131Abstract: A trans-atrial septal catheter system for delivery of a steerable sheath into the left atrium contains three components. The first component is a three-segmented needle-guide wire composed of a distal needle designed to flex sharply in relation to the conjoined looped guide wire segment after fossa ovalis puncture and needle advancement. The distal guide wire loops are advanced into the left atrium maintaining the angled needle in a central location relevant to the loops for preserving an atraumatic position while stabilizing the loops in the left atrium. The elongated proximal extra stiff guide wire segment is conjoined to the looped segment which crosses the fossa ovalis and extends proximally to become externalized to the femoral vein. This segment is extra stiff and significantly elongated to permit catheter and device exchanges. The guide wire serves as a support rail over which the dilator and sheath can be advanced into the left atrium.Type: GrantFiled: November 30, 2021Date of Patent: January 23, 2024Assignee: Boston Scientific Medical Device LimitedInventors: Wesley Robert Pedersen, Paul Sorajja

Publication number: 20230371936Abstract: Anatomical wall crossing systems, devices and related methods are disclosed in this patent document. A transseptal system, for example, can include a guidewire, a dilator, and a deflectable sheath configured to safely deliver a puncture needle through a septal wall associated with the fossa ovalis and into a central region of the left atrium of a heart. The dilator can include a dilator nose having a first outer diameter and a dilator beveled segment, extending proximal of the dilator nose, tapering from a second, greater outer diameter to the first outer diameter. The length and interplay of the puncture needle and the dilator nose can be configured such that the puncture needle is inhibited from bending and impinging upon the left side of the atrial septum of the heart during use. A body of the guidewire can include at least one loop segment to provide stable support in the left atrium for delivery of a diagnostic or therapeutic device along its more proximal portions.Type: ApplicationFiled: April 28, 2020Publication date: November 23, 2023Applicant: Boston Scientific Medical Device LimitedInventors: Wesley Robert Pedersen, Paul Sorajja, William Joseph Drasler

Publication number: 20220151711Abstract: A guide wire that has an atraumatic and flexible loop that expands within a vessel, with indicators that indicate the degree of expansion. The indicators are used to determine the degree of expansion through the use of radio-opaque markers, hydraulic, and electrical signals. The guide wire enables safe passage into target vessels while providing user feedback on inadvertent passage into side branches and diseased segments.Type: ApplicationFiled: July 31, 2020Publication date: May 19, 2022Applicant: Orsus, LLCInventors: Paul Sorajja, Gorav Ailawadi, Daniel P.

Publication number: 20220118261Abstract: A pacing lead for temporary atraumatic placement via transvascular access on an endocardial surface of a heart chamber of an animal body. The pacing lead body has a curled shaft at the distal end region of the pacing lead body having a plurality of electrode sites. Each of the electrode sites is individually connected via an electrode conduction wire to a switch box, which receives generator signals from a pulse generator and directs the electrode generator signal to specific electrode sites. A push-pull element is connected to the lead body distal end. A tension-compression member connects to the push-pull element and provides tension and compression to the push-pull element.Type: ApplicationFiled: October 20, 2020Publication date: April 21, 2022Inventors: Wesley Robert Pedersen, Paul Sorajja, Brett Allyn Williams, William J.
