Tissue grasping devices and related methods
A clip for immobilizing leaflets of a cardiac or venous valve includes a hub having a pair of tangle resistant spring-biased outer arms coupled to an inferior end of the hub and a pair of tangle resistant spring-biased inner arms adjacent to the outer arms and coupled to a superior end of the hub. A delivery catheter may be used to position the valve clip adjacent a target valve while the outer and inner arms are biased in an opened position relative to each other. After the valve leaflets are located between the opened outer and inner arms, the biasing forces may be released to allow the clip to self-close the clip over the valve leaflets.
OPPOSING DISK DEVICE FOR GRASPING CARDIAC VALVE TISSUE
The present disclosure relates to repair devices and methods for repair of regurgitant tricuspid valves. A repair method includes positioning a repair device at a tricuspid valve in a collapsed configuration. The repair device includes a proximal grasping assembly movable between a first position and a second position and a distal grasping assembly movable between a third position and a fourth position. An actuator rod operatively connected to each of the proximal grasping assembly and the distal grasping assembly so that distal movement of the actuator rod moves the proximal grasping assembly proximally and the distal grasping assembly distally.
Surgical system comprising a surgical tool and a surgical hub
A surgical system for use in a surgical theater is disclosed. The surgical system comprises a surgical tool and a surgical hub. The surgical tool comprises a motor, a motor controller in signal communication with the motor, and an end effector configured to perform an end effector function. The end effector is operably responsive to the motor. The surgical hub is in signal communication with the motor controller. The surgical hub is configured to detect a contextual cue within the surgical theater. The motor controller is configured to adjust an operating parameter of the motor based on the contextual cue detected by the surgical hub.
Heart valve sealing devices and delivery devices therefor
An implantable prosthetic device such as might be used to treat poor function of a diseased heart valve in a medical patient includes a body portion and an anchor portion including a plurality of paddles. Clasps attached to the paddles include fixed arms and moveable arms operable to secure the device to the patient's native valve leaflets.
Prosthetic heart valve and systems and methods for delivering the same
A prosthetic heart valve includes a self-expanding wire frame body, a valve disposed in the body, a leaflet clip coupled to the body, and a control element operably coupled to the leaflet clip. The body has a proximal end and a distal end. The leaflet clip is configured to be transitioned between a first configuration in which the prosthetic valve can be inserted into a heart, and a second configuration in which the leaflet clip is disposed to capture a native valve leaflet between the leaflet clip and the wire frame body when the body is disposed in a native annulus of an atrioventricular valve of a heart. The control element extends from the leaflet clip through a ventricle of the heart and out a wall of the ventricle to allow a user to transition the leaflet clip from its first configuration to its second configuration.
CLIP CARTRIDGE, MEDICAL DEVICE, AND ATTACHMENT METHOD FOR MEDICAL DEVICE
A clip cartridge includes a clip unit having a pressing tube, an arm member and a connection portion. The connection portion can transition between a protrusion configuration and an accommodation configuration. The clip cartridge also includes a housing that can accommodate the clip unit. The housing has a stopper that restricts movement of the connection portion and a release mechanism or a groove that permits movement of the connection portion. The stopper is able to restrict movement of the clip unit by contacting the arm member or the pressing tube.
Heart tissue anchors
A heart valve anchor has a body that includes a distal portion, a distal end, a proximal portion, and a proximal end. The distal end and the proximal end define a longitudinal axis. The body has an expandable portion that includes a first radially expandable portion at the distal portion of the body, a second radially expandable portion at the proximal portion of the body, and a root portion disposed between the first and second radially expandable portions. The body has a first configuration adapted to be housed at least partially within a tissue penetrating device, and a second configuration in which the first and second radially expandable portions are partially or fully expanded such that the anchor engages tissue in a region between the first and second radially expandable portions.
CLIP DEPLOYMENT TOOL AND ASSOCIATED METHODS
A laparoscopic device comprising: (a) a housing operatively coupled to a first control and a second control; (b) an end effector operatively coupled to the first control, the end effector comprising a first component and a second component selectively repositionable with respect to one another within an X-Y plane, the end effector also including a third component selectively repositionable with respect to the second component within an Y-Z plane; (c) a laparoscopic conduit extending between the housing and the end effector; and, (d) an occlusion clip deployment device operatively coupled to the end effector and the second control.
TISSUE RETRACTION DEVICE AND DELIVERY SYSTEM
Medical devices and methods of using medical devices are disclosed. An example tissue retraction device includes a first engagement member having a first end and a second end, a second engagement member having a first end and a second end, a first elastic member attached to the second end of the first engagement member, and a first alignment member having a first end, a second end and a lumen extending therethrough. Further, the tissue retraction device has a first length, the first alignment member has a second length, the first elastic member extends within the lumen of the first alignment member and the second length of the first alignment member is less than or equal to the first length of the tissue retraction device.
TISSUE CLIP DEVICES, SYSTEMS, AND TRACTION METHODS
The present disclosure pertains to medical devices. More particularly, the present disclosure pertains to tissue clip devices and related systems and methods. In an embodiment, a tissue clip may include a grasper including jaws at a first end, and a spring portion at a second end, and a longitudinal axis extending along a length of the grasper from the first end to the second end, wherein the spring portion is configured to bias the jaws toward each other. A wedge may be slidably disposed between the jaws such that an apex of the wedge is oriented toward the spring portion. A filament may be coupled to the wedge at a first end of the filament and may extend through a channel of the spring portion of the grasper to a second end of the filament.
