Patent number: 9302083Abstract: Dilators and sheaths for use in minimally invasive vascular therapy are disclosed. In some embodiments, the dilators include a slot that accesses a guidewire lumen within the dilator. These slots facilitate rapid exchange of one dilator for another. In another embodiment, a dilator is sufficiently stiff to facilitate entry, but also designed to facilitate placement of the dilator along a tortuous path.Type: GrantFiled: August 21, 2015Date of Patent: April 5, 2016Assignee: Fischell Innovations, LLCInventors: Robert E.

Publication number: 20140012231Abstract: An elongated hollow tube guiding catheter forming a portion of a guiding catheter includes a proximal end, distal end, and distal section. The distal section includes a curved section and a straight section. The curved and straight sections are shaped for facilitating introduction and retention of the catheter into the ostium of a renal artery. The system includes a dilator inserted into the catheter hollow tube with a curved distal section of the dilator opposingly extending opposite the curved distal section of the guiding catheter hollow tube. The guiding catheter includes a side arm positioned near the guiding catheter's proximal end with a multi-way stop cock fixedly attached onto a proximal end of the side arm tube.Type: ApplicationFiled: September 11, 2013Publication date: January 9, 2014Applicant: FISCHELL INNOVATIONS LLCInventor: ROBERT E.

Patent number: 8591495Abstract: A thin-walled introducer sheath is described. In some embodiments, the introducer sheath includes structural support components, such as wires, used in connection with a polymeric inner coating, a polymeric outer coating, or both. Further, in some embodiments, the wire components are annealed to reduce cold-work-related stresses and hardness. Use of annealed components may enable a reduction in the thickness of the polymeric outer coating in some applications.Type: GrantFiled: March 27, 2012Date of Patent: November 26, 2013Assignee: Fischell Innovations, LLCInventors: Robert E. Fischell, Tim A. Fischell, David R. Fischell

Patent number: 8535294Abstract: The present invention is a carotid sheath that has a proximal portion that is stiffer than the distal portion of the sheath as a result of the proximal portion having a higher durometer of the outer plastic coating of the sheath's proximal portion with a lower durometer for the plastic coating on the more flexible distal portion of the sheath. Another means to increase the flexibility of the sheath's distal portion compared to a stiffer proximal portion is by having a slightly smaller outside diameter for the outer plastic coating of the distal portion of the sheath. A more flexible distal portion of the sheath allows easier access for angiography, angioplasty or stenting when the sheath is used to access the tortuous path encountered when entering the carotid arteries.Type: GrantFiled: June 1, 2011Date of Patent: September 17, 2013Assignee: Fischell Innovations LLCInventors: Robert E.

Publication number: 20120271301Abstract: At the present time, physicians often treat patients with atrial fibrillation (AF) using radiofrequency (RF) catheter systems to ablate conducting tissue in the wall of the Left Atrium of the heart around the ostium of the pulmonary veins. These systems are expensive and take time consuming to use. The present invention circular ablation system CAS includes a multiplicity of expandable needles that can be expanded around a central axis and positioned to inject a fluid like ethanol to ablate conductive tissue in a ring around the ostium of a pulmonary vein quickly and without the need for expensive capital equipment. The expansion of the needles is accomplished by self-expanding or balloon expandable structures. The invention includes centering means so that the needles will be situated in a pattern surrounding the outside of the ostium of a vein. Also included are members that limit the distance of penetration of the needles into the wall of the left atrium.Type: ApplicationFiled: April 22, 2011Publication date: October 25, 2012Applicant: FISCHELL INNOVATIONS LLCInventors: DAVID R. FISCHELL, TIM A. FISCHELL
