  • Patent number: 11857173
    Abstract: Retractors for surgical procedures such as spinal surgical procedures includes a pair of pivotable armatures and a translatable armature. A body for supporting the armatures is provided, with a handle connected thereto. The handle includes a first rotary actuator, wherein a rotation of the first rotary actuator moves the pair of pivotable armatures in opposite arcuate directions, and a second rotary actuator, wherein a rotation of the second rotary actuator translates the translatable armature in a linear direction. Methods of use for the retractors during surgical procedures are also disclosed.

  • Publication number: 20230270432
    Abstract: In one embodiment, a suture attachment catheter configured to repair a heart valve by inserting a suture in a valve leaflet of a beating heart of a patient includes a handle control, a flexible catheter body, and a suture attachment assembly at a distal end of the catheter body. The suture attachment assembly can include a rail between a distal clamping jaw hingedly attached to the rail, and a proximal clamping jaw. One of the proximal clamping jaw or distal clamping jaw can be selectively slideable with respect to the other on the rail using a jaw actuator of the control handle to adjust a distance between the proximal clamping jaw and the distal clamping jaw. A needle can be selectively slideable within the catheter body by using a needle actuator of the proximal handle control to penetrate a valve leaflet and insert a suture through the valve leaflet when the valve leaflet is captured between the proximal clamping jaw and the distal clamping jaw.

  • Publication number: 20210282764
    Abstract: Disclosed herein are minimally invasive systems and methods for intravascularly accessing the heart and performing a transcatheter repair of a heart valve by inserting a suture as an artificial chordae into a heart valve leaflet. In various embodiments, such systems and methods can be employed in other heart valve repair procedures such an edge to edge repair to coapt leaflets by inserting one or more sutures that retain the leaflets in a coapted positioned or inserting a suture to repair a tear in a leaflet, for example.
