An apparatus includes at least one link and a plurality of beads. The plurality of beads is joined using the at least one link. The housing includes a magnet chamber. The magnet is configured to emit a magnetic field to magnetically bias the loop toward the contracted configuration. The magnet is sized and configured to move within the magnet chamber. A consistent angular orientation of adjacent housings is determined by at least one of the following adjustment parameters: a magnitude of the magnetic fields of adjacent magnets disposed in the adjacent housings by altering a distance between the adjacent housings, a directionality of the adjacent magnets within adjacent magnet chambers by allowing for twist of the magnet within the magnet chamber, or a freedom of the adjacent magnets to move within the adjacent magnet chambers by allowing the magnets to move laterally within the respective magnet chambers.

An apparatus includes a first shaft extending distally from a proximal end to a distal end. The first shaft is sized to fit within an esophagus of a patient. The first shaft includes a first shaft lumen extending distally to the distal end. The apparatus further includes a second shaft slidably positioned within the first shaft lumen. The second shaft is sized to fit within the shaft lumen and extend through the transverse bore. The second shaft is configured to receive a guide element and a sphincter augmentation device so that the sphincter augmentation device may be deployed through an interior of the esophagus to an exterior of the esophagus.

A device may include an elongated housing formed of an optically transparent material, the housing extending from a proximal end to a distal end and including a lateral wall extending from the proximal end to a distal tip of the housing, the housing defining a lumen extending into the housing from a proximal opening in the proximal end of the housing. The device also may include a first port extending through the lateral wall of the housing to open the lumen of the housing to an exterior of the housing, the first port being sized and shaped to receive therein a target portion of tissue to be inspected and/or treated.

An apparatus for treating hemorrhoids including a first member having a proximal portion, a distal portion and a window formed therein to receive tissue. A third member is operably connected to the second member and movable between a first position and a second position, the third member having a clamping surface movable to the second position to provide a clamping force on tissue received through the window. Movement of the second member in a distal direction moves the third member in the distal direction toward the second position, the third member movable in a distal direction until such movement is limited due to contact and compression of tissue within the window, the second member continuing movement in the distal direction after movement of the third member in the distal direction has been limited.

A percutaneous device for closing blood vessels has a main body in which a distal clip and a proximal clip connected to each other by a tie rod are accommodated, an abutment element, and a handle for maneuvering the distal and proximal clips, the abutment element and the tie rod. The distal clip has a proximal housing, and the proximal clip has a distal housing and a proximal housing. The tie rod is positioned inside the housings when the distal and proximal clips are inserted inside the main body, so as to not interfere with correct sliding thereof.

The present disclosure relates to endoscopic reposable surgical clip appliers having a shaft assembly. The shaft assembly includes a spindle, pusher bar, and a barrel assembly. The spindle and pusher bar are each translatably supported within the shaft assembly. The barrel cam assembly includes a first portion in mechanical communication with the spindle and a second portion in mechanical communication with the pusher bar. Translation of the spindle effectuates rotation of a portion of the barrel cam assembly and the rotation of the portion of the barrel cam assembly effectuates translation of the pusher bar.

An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

A medical device has an artificial contractile structure including at least one contractile element adapted to contract a hollow body organ in such a way that said contractile element is adapted to be in a resting position or in an activated position, the activated position being defined with the contractile element constricting the hollow body organ and the resting position being defined with the contractile element not constricting the hollow body organ. The medical device further includes a tensioning device adapted to apply a force so as to tighten the contractile element around the hollow body organ, the tensioning device having a flexible transmission with a tensioning element arranged in a sheath. The sheath has an inner coiled wire coiled in a first direction, and an outer coiled wire surrounding the inner coiled wire and coiled in a second direction opposite to said first direction.

An epicardial implant having a positioning device that defines an open interior. The positioning device is configured to be detachably coupled with an implant delivery device such that the positioning device may be detached from the implant delivery device after the implant is in place about an atrial appendage. The positioning device has first and second sides with a distal end that couples the first and second sides. The implant includes an expandable cuff coupled with the positioning device. The positioning device is configured to selectively move the expandable cuff toward and away from an atrial appendage to position the expandable cuff in a desired position relative to the atrial appendage. The expandable cuff is expandable into at least a portion of the open interior of the positioning device to physically occlude a base of the atrial appendage following placement of the expandable cuff into the desired position.

The present teachings provide methods for resizing, reducing, and closing left atrial appendage. Specifically, a percutaneous trans-septal access is first established from outside the body to a patient's LAA. At least two tissue anchors are then implanted inside the LAA chamber and along the tissue wall. At least one anchor is implanted near the opening of the LAA camber. Both tissue anchors are pulled together so that the wall of the LAA chamber collapse. The LAA chamber is therefore resized, reduced, and/or closed off completely. This closure method and system could be used alone in closing LAA chamber. This closure method and system could also be used in addition to other treatment mechanisms, such as filling the LAA chamber with space-filling material, then closing off its opening.
