Patent number: 10478214Abstract: An intraluminal scoring system for expanding an opening within an intraluminal passage includes a balloon catheter which is positioned alongside plaque lining a wall of the intraluminal passage. A wire is positioned between the balloon and the plaque so that the inflation of the balloon restricts the wire between the balloon and the plaque. After the balloon is inflated, a mechanical vibration is induced in the proximal end of the wire by a lithotripter actuator. The vibration travels through the wire to the distal portion, causing the wire to impact the plaque lining the wall of the passage causing scoring, compression, or fragmentation of the plaque.Type: GrantFiled: November 6, 2014Date of Patent: November 19, 2019Assignee: Cook Medical Technologies LLCInventor: Elizabeth A Eaton

Patent number: 10456127Abstract: An assembly and method for the protection of medical personnel from accidental suture needle sticks is described. The assembly includes a case containing a needle which can be retracted when not in use. The needle is extended and retracted through the engagement of a needle driver which compresses a compressible member. The compressible member exerts a force on the needle which in turn extends the needle's point beyond the casing so that the user can suture tissue. Disengaging the needle driver retracts the needle point which protects the user from accidentally receiving a needle prick from a contaminated needle between punctures.Type: GrantFiled: July 10, 2017Date of Patent: October 29, 2019Inventor: Seena Monjazeb
