A clip applier may be configured to apply a surgical clip. The clip applier may include a first jaw member and a second jaw member, where the first jaw member is configured to pivot between an open configuration and a closed configuration. The clip applier may also include a first leaf spring configured to bias the first jaw member into the open configuration, and a tubular member configured to advance over the first jaw member to cam the first jaw member into a closed configuration against the bias of the first leaf spring. The clip applier may further include a second leaf spring configured to bias the second jaw member into the open configuration, and a tubular member configured to advance over the second jaw member to cam the second jaw member into a closed configuration against the bias of the second leaf spring.

Clip applier

A clip applier may be configured to apply a surgical clip. The clip applier may include first and second jaw members configured to engage the surgical clip, an actuating member configured to pivot at least one of the first and second jaw members between an open configuration and a closed configuration, and a stabilizing member configured to engage the surgical clip. The stabilizing member may be configured to move longitudinally with respect to the clip applier from a distal position at least partially between the first and second jaw members to a proximal position at least partially between the first and second jaw members. Movement of the stabilizing member between the distal position and the proximal position may be actuated by at least one of the first jaw member, the second jaw member, and the actuating member.

Clip applier with stabilizing member

A clip applier may be configured to apply a surgical clip and have a pair of jaw members. Each of the jaw members may have an inner surface and a stabilizing member extending from the inner surface. Each of the jaw members may be configured to engage a distal portion of a leg member of the surgical clip. The stabilizing members may be configured to be positioned on opposite lateral sides of a proximal portion of the surgical clip to reduce lateral movement of the surgical clip. An inner portion of each of the stabilizing members may be spaced apart from the opposing jaw member in an open configuration, and each of the jaw members may have a channel on the inner surface to receive the opposing stabilizing member in a closed configuration.

A dilating cannula includes a radially expandable flange and an expandable shaft. The radially expandable flange is disposed at a proximal end portion of the dilating cannula and includes two or more sectors that are each independently movable. The expandable shaft extends from the proximal end portion to a distal end portion of the dilating cannula and defines an inner passageway of the dilating cannula and includes two or more arms. A first branch of the two or more arms extends from one end of the base section and a second branch of the two or more arms extends from another end of the base section. The first branch is connected to a first sector of the two or more sectors of the radially expandable flange and the second branch is connected to a second, different sector of the two or more sectors of the radially expandable flange.

A system and method for extracting a pVAD device that is implanted with a distal portion in an aorta of the heart and a drive line extending across an inter-atrial septum and out of the body via a superior vessel of the venous vasculature, include a first device that is introduced into a femoral artery and through the descending aorta used to engage a distal part of the pVAD device in the aorta of a patient using an instrument. A second, cutter, device is introduced into the venous vasculature superior to heart, advanced to a position adjacent the inter-atrial septum, and used to cut the pVAD drive line adjacent to the inter-atrial septum. After cutting, a first portion of the pVAD is withdrawn from the body via the venous vasculature, and a second portion is withdrawn from the body via the femoral artery.

Devices for use in extracting percutaneous ventricular assist devices

A surgical clip cartridge, assembly, and method are provided for the storage, delivery, and loading of clips, such as those used in a surgical ligating process. The surgical clip cartridge includes a base portion extending in a longitudinal direction, the base portion having a bottom surface and defining a mounting groove for attaching the base portion onto a surgical instrument shaft. The base portion further includes a plurality of dividers extending from the base portion in a direction opposite of the bottom surface, and the plurality of dividers may be used to retain individual surgical clips therebetween for subsequent retrieval and loading onto a clip applier. The attachment of the surgical clip cartridge to the surgical instrument shaft enables the surgical clip cartridge to be deployed intracorporeally for use in surgical operations requiring applications of multiple surgical clips.

Snap-on surgical clip cartridge

A ligation clip applier is provided. The clip applier includes: a pair of jaws; a distal clevis tube to which the jaws are pivotally mounted; a proximal clevis tube located behind the distal clevis tube, wherein the distal clevis tube and the proximal clevis tubes move axially with respect to each other; a clip lock actuator fixed to one of the proximal and distal clevis tubes; and a distal pushrod extending through the distal and proximal clevis tubes and forming a camming connection with the jaws configured to close and move the jaws toward a proximal direction toward the clip lock actuator when the distal pushrod is moved in the proximal direction. A method for applying a clip on a vessel is disclosed.

Manual surgical ligation clip applier

A narrow profile surgical ligation clip has two legs with clamping surfaces joined by a hinge near the proximal ends, allowing the clip to reversibly open and close. A locking mechanism is proximal to the hinge to bias or lock the clip closed, including first and second jaw structures spaced on opposite sides of a longitudinal axis of the clip thereby defining a locking space therebetween. In one embodiment, a wedge or buttress body moves by application of an external force applied to a proximal end of the clip towards the hinge to move into the locking space such that one or more outer surfaces or projections of portions of the body fit into or abut against complementary surfaces or other parts of the locking mechanism or clip assembly to bias or lock the clip in a closed position and provide additional closing force to the inner clamping surfaces.

Narrow profile surgical ligation clip

An applier for ligation clip is provided. The applier includes: an outer tube having mounting bosses; a pair of jaws pivotally connected to the mounting bosses, the jaws having actuating projections; a feed tube located in the outer tube and configured to move axially within the outer tube, the feed tube having actuating slots in which the actuating projections are located; a clip lock arm located in the outer tube and configured to move axially within the outer tube; and a clip advance arm located in the outer tube and configured to move axially within the outer tube, the clip advance arm having flexible pinchers at one end of the clip advance arm. A method of applying a ligation clip is also disclosed.

Dilating cannula with radially expandable flange

A suture placement device provides a lateral extension element, such as a slotted t-bar or wings, which is inserted into a trocar and deployed to position receptor ports about 1 cm from the trocar. The trocar is removed, and stylet guides are deployed to create a path from the housing to the receptor ports, thereby creating a suture path with segments from the outside of the device to each port, and between ports. A stylet is inserted through the suture path, and used to pull a suture of choice through the path. A stylet guide has a partially extended position to permit precise intra-muscular location of an anesthetic injection before being fully deployed. The t-bar is rotated back to a vertical position to permit removal to of the suture placement device so that the suture can be tied.

Apparatus and method for fascial closure device for laparoscopic trocar port site and surgery

An end effector actuation system includes a shaft assembly having an outer shaft with an internal lumen and an actuation rod slidably received in the lumen, the outer shaft having a distal end portion that is compressible only when the actuation rod is absent from the lumen in the distal end portion, a locking boss provided on the distal end portion; and an end effector assembly having a receiving opening and a retention pocket, wherein the receiving opening is sized to receive the compressed distal end portion of the outer shaft and the retention pocket is sized to receive the locking boss when the distal end portion is uncompressed due to the presence of the actuation rod in the lumen of the distal end portion.

End effector connection and actuation systems

A suture placement device is inserted into an endoscopic trocar port site. A pivot bar with a pair of receptor ports is moved from a folded to an extended position below the fascia. The trocar port is removed over the device as the pivot bar is pulled upward against the fascia. A pair of stylet guides are deployed from two sides of the device housing, and intercept the receptor ports, thereby creating a suture path through the first guide, through a channel in the pivot bar between the receptor ports, and through the second guide. A stylet is directed through the suture path to pull a suture through the path. The guides are refracted, the pivot bar is folded, the device is removed, and the suture is tied. A stylet guide may have a partially deployed position to accurately inject an anesthetic at a desired intra-muscular layer.
