Patent number: 9254143Abstract: A hollow guidewire with a shapeable distal end, for removing tissue from a body lumen, such as a coronary artery. The hollow guidewire comprises an elongate, tubular guidewire body that has an axial lumen. A tissue removal assembly, such as a rotating drive shaft, is positioned at or near a distal end of the tubular guidewire body and extends through the axial lumen. Actuation of the tissue removal assembly removes occlusive material in the body lumen.Type: GrantFiled: August 31, 2007Date of Patent: February 9, 2016Assignee: REVASCULAR THERAPEUTICS, INC.Inventors: Christopher Huynh, Nestor Aganon, Michael Carley, Victor Chechelski, Rudolfo Sudaria

Patent number: 9168111Abstract: Root canal abutment devices and methods which facilitate the adjustment or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured within a pulp chamber of a pre-existing tooth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy sleeves or plates or elements extending along the abutment. Each of the sleeves has a length with at least one curved or arcuate portion. Energy may be applied to the elements such that the arcuate portion flattens to allow for the oral appliance to be placed thereupon while removal of the energy allows the elements to reconfigure into its curved configuration thereby locking the oral appliance to the abutment. Removal of the oral appliance may be effected by reapplication of energy to the elements.Type: GrantFiled: February 4, 2011Date of Patent: October 27, 2015Assignee: Rodo Medical, Inc.Inventors: Young Seo, Jianhua Yang, Victor Chechelski, Jong Gil Park

Patent number: 9113955Abstract: Systems and methods for crossing stenosis, partial occlusions, or complete occlusions within a body lumen. The systems generally include an elongate member such as a hollow guidewire that houses a rotatable and translatable drive shaft. The drive shaft typically has a distal portion that is advanced to create a path in the occlusive material that is large enough to allow the hollow guidewire to cross the occlusive material.Type: GrantFiled: February 26, 2014Date of Patent: August 25, 2015Assignee: Revascular Therapeutics, Inc.Inventors: Gerardo V. Noriega, Victor Chechelski, Rudolfo Sudaria

Patent number: 8651864Abstract: Shape memory dental retention systems which facilitate the adjustment or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured to an anchoring implant bored into the bones within the mouth. The abutment assembly has a projecting abutment portion with one or more shape memory material sleeves or plates or elements extending along the abutment. Each of the sleeves has a length with at least one curved or arcuate portion. Energy may be applied to the elements such that the arcuate portion flattens to allow for the oral appliance to be placed thereupon while removal of the energy allows the elements to reconfigure into its curved configuration thereby locking the oral appliance to the abutment.

Publication number: 20130289578Abstract: A device for capturing a clot in a blood vessel comprises an outer shaft, an inner shaft slidably disposed in a lumen of the outer shaft, and clot capture arms secured to a distal end of the inner shaft. The device is navigated and advanced through the vasculature to reach the location of a blood clot. An anchoring element on the outer shaft is expanded to anchor the device at the location of the blood clot. The clot capture arms are extended from the open end of the outer shaft. As the clot capture arms are extended, the distal portions of the arms gradually open into radially inwardly curved configurations to capture the clot. With the clot captured, the arms are retracted back into the outer shaft along with the clot. The anchoring element is then collapsed, and the device, with the clot captured therein, is retracted from the vasculature.Type: ApplicationFiled: April 9, 2013Publication date: October 31, 2013Applicant: YAWA-MED, INC.Inventors: GERARDO V. NORIEGA, RODOLFO B. SUDARIA, SARAH E. VAN KEULEN, SOFIA A. POUR, KRISTIAN C. HOCKENSON, VICTOR CHECHELSKI

Patent number: 8491303Abstract: Oral appliance activation devices and methods which are used to facilitate the securement, adjustment, or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured to an anchoring implant bored into the bones within the mouth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy elements extending along the projecting abutment portion. Energy may be applied to the elements via the activation devices directly over or adjacent to the oral appliance to actuate the elements and thereby either secure or loosen the oral appliance relative to the abutment.Type: GrantFiled: February 4, 2011Date of Patent: July 23, 2013Assignee: Rodo Medical, Inc.Inventors: Young Seo, Jianhua Yang, Victor Chechelski, Jong Gil Park
