A surgical system is disclosed including a replaceable staple cartridge stored in a packaging that includes a first RFID tag including first encrypted information. The replaceable staple cartridge includes a second RFID tag including second encrypted information. A retainer includes a third RFID tag including third encrypted information. A controller includes a first key to decrypt the first encrypted information. The controller releases a second key if the first encrypted information is recognized. The controller uses the second key to decrypt the second encrypted information. The controller releases a third key if the second encrypted information is recognized. The controller uses the third internal key to decrypt the third encrypted information. The controller prevents a surgical instrument from performing a staple firing stroke if at least one of the first encrypted information, the second encrypted information, and the third encrypted information is unable to be recognized.

An endoscopic tissue resecting system that includes a reciprocating rotary surgical instrument for cutting tissue that includes a planetary gear assembly to vary rotational speed. A method of cutting and detaching tissue includes positioning an outer member such that tissue is located within a window in the outer member, engaging the tissue with an inner member, and simultaneously rotating at an increased speed relative to a rotary driver and translating the inner member to cut the tissue. A tangential cutting force is applied to the tissue with the inner member to mechanically cut and detach the tissue.

Tap guide assembly devices, systems, and methods are disclosed herein. A tap guide assembly can have a body assembly, a tension pin assembly, a tension spring, and a setscrew. The body assembly can have an elongate body and a drill bushing. The drill bushing can have a diameter that is less than the diameter of the elongate body and can be positioned within a portion of the elongate body. The tension pin assembly can have a pin and a collar and can be configured to be received within the body assembly. The tension spring can be positioned proximate to the collar. The setscrew can be securely positioned proximate to the tension spring and within the second opening of the elongate body.

A translating polyaxial bone screw assembly for anchoring a connecting rod to a spinal vertebra comprises a bone screw having a threaded shank and a head coupled to a yoke. The yoke has at one end a rod receiving channel for receiving a connecting rod and an opposite end that is coupled to the bone screw by a coupling assembly. The coupling assembly couples the yoke for polyaxial movement relative to the bone screw and for translational movement of the yoke in a direction transverse to the axis of the bone screw. The coupling assembly comprises a biasing element supported for joint movement with the yoke that provides a manually surmountable tension force between the yoke and bone screw head that is maintained during polyaxial and translational movement. A fastening element is supported by the yoke for securing the connecting rod between the fastening element and the coupling assembly.

An aortic punch includes a cylindrical barrel, a cylindrical plunger movably mounted within the barrel, a blade shaft movably mounted within a distal end of the barrel and having a first cutting tool at a distal end thereof, the first cutting tool configured to form a first cut in a wall of a blood vessel, and a cylindrical punch body movably mounted within a distal end of the barrel and about the blade shaft and having a second, circular cutting tool configured to form a circular hole in the wall of a blood vessel around the first cut.

The present invention relates to a surgical device for clamping in tissue, wherein the surgical device comprises a first clamp, a second clamp, and an elongated dimensionally stable connector and its use within a minimally invasive or open surgical treatment for effecting tissue to be self-hold.

Delivery devices configured to deliver therapeutic and visualization devices to a surgical site are disclosed. An example delivery device may include a proximally disposed handle; a shaft extending distally from the handle, the shaft including a therapeutic device lumen configured to deliver a working end of a therapeutic device therethrough, a first portion of the shaft being steerable; and a space-making element disposed proximate a distal end portion of the shaft and configured to separate biological tissues to create or expand a working space. At least a portion of the space-making element may be reconfigurable between a retracted configuration and an expanded configuration.

A method for forming a surgical snare, the method comprising: providing a plurality of filaments; braiding the plurality of filaments together so as to form a braided tubular construct comprising: a proximal tube having an open proximal end, an open distal end, and a proximal tube lumen extending there between; a distal tube having an open proximal end, an open distal end, and a distal tube lumen extending there between; and a loop region disposed between the distal end of the proximal tube and the proximal end of the distal tube, the loop region comprising at least one loop structure, the at least one loop structure comprising at least three of the plurality of filaments braided together; inserting the distal end of the distal tube into the open distal end of the proximal tube and into the proximal tube lumen such that (i) the distal tube is disposed in the proximal tube lumen such that the at least one loop structure extends distally of the distal end of the proximal tube in the form of at least one loop, and (ii) the distal tube lumen extends from a point located distal to the proximal end of the proximal tube to the at least one loop.

A treatment method according to one aspect of the present disclosure may include inserting a first closing member and a second closing member into a tubular organ having at least one concaved area, and closing a part of the tubular organ with the first closing member and the second closing member in a state where the at least one concaved area is located between the first closing member and the second closing member. The method may further include disposing a holding member between the first closing member and the second closing member, and suctioning gas within the part of the tubular organ between the first closing member and the second closing member and contacting the holding member with a portion of the at least one concaved area.

Disclosed herein are catheters for use with clot treatment systems, and associated devices and methods. The catheter can include an outer sheath, an outer sheath drive component operably coupled to the outer sheath, a guidewire sheath slidably disposed within the outer sheath, a guidewire sheath drive component operably coupled to the guidewire sheath and slidably disposed within the outer sheath drive component, and a clot treatment component. During a clot treatment procedure, the outer sheath drive component can be moved proximally and/or the guidewire sheath drive component can be moved distally to cause corresponding movement of the outer sheath and/or guidewire sheath, respectively, and transition the catheter between a first configuration, in which the clot treatment component can be positioned within the outer sheath, and a second configuration, in which at least part of the clot treatment component can extend beyond the outer sheath.
