Patent number: 10881834Abstract: A catheter integral with a valved needle-free connector provides a safety catheter device configured to receive a blunt cannula and sharp needle forming an insertion mechanism. The sharp needle is mounted within a needle tube and a control handle is used to slide the sharp needle out of and into the protective needle tube. When the insertion mechanism is mounted to the connector and the control handle is used to slide the sharp needle out of the tube, a blunt cannula first moves into contact with and enters the bore of the valve mechanism of the connector opening it and protecting it from damage that may be caused by the sharp needle. The sharp needle is then extended through the connector and extends out the distal end of the catheter so that a venipuncture procedure may be performed to properly locate the catheter in the patient's circulatory system. Once located, the needle may be retracted into the insertion mechanism, the insertion mechanism disconnected from the connector, and discarded.Type: GrantFiled: July 14, 2017Date of Patent: January 5, 2021Assignee: CareFusion 303, Inc.Inventors: Karl R.

Publication number: 20200330088Abstract: An annuloplasty implant comprising an elongate member configured to be anchored to tissue of a heart, and to move between an elongate configuration and a shortened configuration and a tensioning member. The tensioning member can define a first segment and a second segment such that the first segment extends between a first tensioning-member end and a turn of the tensioning member, and the second segment extends between the turn and the second tensioning-member end. The tensioning member extends along the elongate member such that the elongate member can slide relative to the tensioning member and such that applying tension to the tensioning member causes the elongate member to move from the elongate configuration to the shortened configuration, which can cause the implant to reshape an annulus of a heart valve.Type: ApplicationFiled: June 29, 2020Publication date: October 22, 2020Inventors: Hiroatsu Sugimoto, Aaron M. Call, Karl R. Leinsing

Patent number: RE46927Abstract: The present invention relates to an external heart device, having a layered band dimensioned to be received around a patient's heart, which also includes at least one fillable chamber between the layers in the band that functions to apply localized pressure to the outside of the heart when filled. More particularly, the fillable chambers are positioned such that they exert an inward radial force on a heart valve. Areas between the fillable chambers may also be sized and positioned to form a bridge of little to no pressure over the vascular structures of the heart.Type: GrantFiled: January 10, 2014Date of Patent: July 3, 2018Assignee: Mardil, Inc.Inventors: Karl R.
