Patent number: 10543043Abstract: The present disclosure relates to a system and method for providing laser energy through a catheter towards a second end portion of the catheter. Based on a characteristic of the laser energy multiple types of ablation therapy may be implemented. A first ablation therapy is directed at the target site when the laser energy at the second end portion of the laser energy delivery system has a first characteristic. A second ablation therapy is directed at the target site when the laser energy at the second end portion of the laser energy delivery system has a second characteristic. The first ablation therapy may be an optical ablation therapy wherein the laser energy is directed at the target site as optical energy and the second ablation therapy may be a pressure wave ablation therapy wherein pressure waves are directed at the target site as pressure wave energy.Type: GrantFiled: November 4, 2018Date of Patent: January 28, 2020Assignee: THE SPECTRANETICS CORPORATIONInventors: Richard Fiser, Kenneth P Grace

Publication number: 20160199575Abstract: Featured is a vascular access device such as an IV catheter device including a housing, a tubular member and a seal member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal portions. The tubular member is coupled to the housing distal portion so it is fluidly coupled to the chamber. The seal member is disposed within the chamber and the securing mechanism secures the seal member distal end to the housing proximal portion so the seal member is sealingly and compressibly retained between a chamber proximal end and the securing mechanism. Such a seal member also is constituted so a portion of the seal member moves axially responsive to an axial force applied to the proximal end.Type: ApplicationFiled: December 22, 2015Publication date: July 14, 2016Inventors: Richard Belley, Richard Fiser, Eugene Weilbacher

Publication number: 20160022303Abstract: Methods and systems for removing an object, such as a lead, from formed tissue are provided. Specifically, a lead removal sleeve is configured to engage patient formed tissue at a dilation engagement point. The lead removal sleeve is configured to dilate the formed tissue around a lead, while providing an inner lumen with clearance for the lead to move within the sleeve. It is an object of the lead removal sleeve to support the formed tissue, and even forces of the formed tissue, with a structure of the sleeve as the lead is removed from a patient. The methods and systems are well suited for use in cardiac pacing or defibrillator lead explant procedures.Type: ApplicationFiled: October 7, 2015Publication date: January 28, 2016Inventor: Richard Fiser

Patent number: 9089673Abstract: A safety shield incorporating a locking clip to prevent inadvertent sticks or punctures by a needle is provided. The needle can be a needle cannula or other piercing member, disposed in a sliding orientation in the safety shield, such that the needle slides within the locking clip between an aperture at a proximal end of the locking clip and a trigger hole at a distal end of the clip. Upon withdrawal of the needle after use, a binding orientation is triggered when the needle tip is withdrawn from the trigger hole. As further protection to the bi-directional lock afforded by the binding orientation, the needle is provided with a safety stop to prevent movement of the needle tip through the aperture. In other aspects, the safety shield includes a trigger bushing, in which the needle cannula is slidably received, that is sized larger than the aperture.Type: GrantFiled: August 1, 2013Date of Patent: July 28, 2015Assignee: Covidien LPInventors: Richard Fiser, James L.

Publication number: 20080082053Abstract: Featured is a medical infusion device for vascular access with enhanced flashback visualization that includes a hub assembly having a flashback chamber. The hub assembly includes a proximal portion, a distal portion and a substantially transparent window section intermediate the proximal portion and distal portion. A needle is coupled to the flashback chamber so that fluid flows through the lumen of the needle into the flashback chamber after the needle is inserted into a blood vessel. A contrasting member is disposed on at least a portion of the hub assembly, so that when blood enters the flashback chamber, the contrasting member provides a high-contrast background when viewed through the window section.Type: ApplicationFiled: September 27, 2007Publication date: April 3, 2008Inventors: James Carlyon, Eugene Schrader, Richard Fiser
