Surgical instruments with torsion spine drive arrangements
Surgical instruments with articulatable surgical end effectors and rotary driven flexible drive members.
Ultrasonic surgical instrument with movable rigidizing member
A surgical apparatus includes a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and a rigidizing member. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide includes a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section includes a first member and a second member. The second member is longitudinally translatable relative to the first member. The end effector includes an ultrasonic blade in acoustic communication with the waveguide. The rigidizing member is configured to selectively engage at least a portion of the articulation section to thereby selectively provide rigidity to the articulation section.
REMOVABLE MEDICAL RETRACTOR TIP
The exemplary embodiments illustrated provide the discovery of systems, methods, and apparatuses of removable tips for use with medical retractors in laparoscopic surgery that provide many benefits, including but not limited to, improving the efficiency and navigation to the target anatomy while maintaining adequate exposure to the target anatomy.
CATHETER SYSTEM FOR INTRODUCING EXPANDABLE MEDICAL DEVICE AND METHODS OF USING SAME
A catheter system includes a catheter, a recovery sheath, and an outer sheath assembly. The catheter includes an elongate body having an expandable medical device coupled with a distal end thereof. The recovery sheath is disposed around a proximal section of the catheter body, and is sized and shaped to receive the expandable medical device therein. The recovery sheath is axially movable relative to the catheter body. The outer sheath assembly includes an outer sheath disposed over the catheter body. The outer sheath includes an elongate body that extends from a proximal end to a distal end, where the proximal end of the outer sheath body is positioned distally of the recovery sheath. The outer sheath includes a retention section sized and shaped to receive the expandable medical device therein and constrain the expandable medical device in a stored configuration. The outer sheath is removable from the catheter body.
SURGICAL INSTRUMENTS WITH TORSION SPINE DRIVE ARRANGEMENTS
Surgical instruments with articulatable surgical end effectors and rotary driven flexible drive members.
TISSUE ENGAGEMENT DEVICE
Medical devices and methods of using medical devices are disclosed. An example tissue engagement device includes a first actuation member including a body coupled to a first jaw and a second jaw at a pivot point, wherein the body is designed to shift between a first configuration and a first compressed configuration and a second actuation member coupled to the first actuation member at the pivot point and at a fixation point, wherein the second actuation member is designed to shift between a second configuration and a second compressed configuration. Further, shifting the first actuation member from the first configuration to the first compressed configuration, shifting the second actuation member from the second configuration to the second compressed configuration, or both, shifts the first jaw and the second jaw between a closed configuration and an open configuration.
Systems and methods for off-axis tissue manipulation
A surgical system and method for manipulating tissue. A steerable assembly comprises a steerable instrument and a deformable conduit. The steerable instrument comprises a control element and a deflectable portion operatively connected to the control element. The steerable assembly is directed through an access cannula such that at least a portion of the steerable assembly protrudes from the distal end of the access cannula. The steerable instrument is actuated to move a deflectable portion of the steerable instrument and a distal portion of the deformable conduit away from the longitudinal axis of the access cannula so that the deformable conduit assumes a deformed position. The steerable instrument is retracted from the deformable conduit.
HEART VALVE LEAFLET CAPTURE DEVICE
The invention provides a heart valve leaflet capture device (250) comprising a cardiac catheter probe having a proximal end for manipulating the device (250) and a distal end terminating in a transvalve element (256). The transvalve element (256) is configured to pass through a heart valve generally parallel to a longitudinal axis of the catheter and includes two or three leaflet gripping elements (252). The leaflet gripping elements (252) are individually movable by operation of an associated actuating mechanism (260) between a radially retracted position, in which they are withdrawn with respect to the transvalve element (256), and a capture position, in which they diverge outwardly at an acute angle from the transvalve element (256). In the capture position, each leaflet gripping element (252) defines a convergent capture zone that is directed towards the edges of a target valve leaflet and in which the target valve leaflet may be captured.
HEART VALVE REGURGITATION ANCHOR AND DELIVERY TOOL
A heart valve anchor apparatus may include a body having a proximal portion and a distal portion. The body may include a first radially expandable portion at the proximal portion of the body, a second radially expandable portion at the distal portion of the body, and a root portion extending from the first radially expandable portion to the second radially expandable portion, the root portion having an outer extent. The first radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. The second radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. In an unstressed configuration, the body may define a longitudinal centerline that extends away from a plane tangent to the root portion.
Suture Passer Needle
This invention relates to surgical suturing devices and methods by which suture may be passed through tissue during surgery, and, more particularly, to an improved blade of a suture passer needle. The suture passer needle includes a first side, a second side, and a blade disposed at an end of the needle. The blade has a first edge extending from the first side of the needle and a second edge extending from the second side of the needle, which converge to a tip of the blade. A notch is disposed in the blade and forms an opening in the first side of the blade. The blade also has one or more cutout portions distal and/or proximal the notch, which minimize the stress and strain placed on the blade. The suture passer needle can be incorporated into surgical suturing devices or suture passer devices to pass suture through a tissue body.
