A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.

A catheter system having one or more needle position indicators to assist an operator in withdrawing the introducer needle to a “parked” position, as part of a catheterization procedure, wherein the needle position indicator provides a visual indication to the operator.

A surgical stapling assembly comprising an anvil, a cartridge channel, a staple cartridge configured to be operably positioned in the channel, a firing member, and a ramp is disclosed. The channel comprises a base, an elongate internal slot, and a proximal channel opening defined in the base. The elongate internal slot comprises an encased internal passageway. The proximal channel opening is separate from the elongate internal slot. The firing member is movable from a first position to a second position distal to the first position. The firing member comprises a lateral extension configured to be received in the encased internal passageway as the firing member travels through the elongate internal slot during a firing motion. The proximal channel opening is configured to indicate when the firing member is in the first position. The ramp is for guiding the lateral extension into the encased internal passageway during the firing motion.

A fastener cartridge can comprise fastener cavities arranged in longitudinal rows. A first fastener having a first configuration and a second fastener having a second configuration can be stored within a longitudinal row. First fasteners having a first configuration can be stored within a first longitudinal row and second fasteners having a second configuration can be stored within a second longitudinal row. Each first fastener can have a proximal leg, or leg portion, extending at a first proximal angle and a distal leg, or leg portion, extending at a first distal angle and each second fastener can have a proximal leg, or leg portion, extending at a second proximal angle and a distal leg, or leg portion, extending at a second distal angle. The first proximal angle can be different than the second proximal angle and/or the first distal angle can be different than the second distal angle.

According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a driver, a clip assembly, a needle assembly, and biasing element. The clip assembly is disposed in mechanical cooperation with the driver. Rotation of the driver results in longitudinal translation of the clip assembly. The needle assembly is selectively engaged with the clip assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.

An example device includes a first sensor to sense a first value representative of distance to a bone wall inside a patient; a second sensor configured to sense a second value representative of a distance to an implant component inside the patient; processing circuitry configured to process the first value and the second value; and transmitter circuitry configured to generate an output based on the first value and the second value.

An example method includes registering a virtual model of a portion of a bone of a patient with a corresponding observed portion of the bone, the virtual model including a representation of a wall of the bone; registering a virtual model of an implant component with a corresponding observed implant component; and indicating, based on the registered virtual model of the portion of the bone and the registered virtual model of the implant component, a position of at least a portion of the implant component relative to a position of the wall of the bone.

Devices, systems and methods for altering functioning of a tissue/organ by application of force thereto. In one preferred embodiment, a device for reducing or preventing regurgitation of blood through a valve of a heart is provided. A device may include a main body having a segment adapted to apply force to a surface of tissue/organ; a member that applies counterforce to the force applied by the segment; and an adjuster that is manually operable to change the force applied by the segment. The adjuster can be manually operated before or after anchoring of the device to the tissue/organ.

A surgical instrument is disclosed comprising an end effector including a first jaw and a second jaw, wherein the first jaw is rotatable relative to the second jaw, and a closure system configured to close the first jaw during a closure stroke. The surgical instrument further comprises an articulation joint rotatably connecting the end effector to the shaft, an articulation system configured to articulate the end effector relative to the shaft, and a firing system operably engaged with the electric motor, wherein the firing member is configured to move through the end effector during a firing stroke. The surgical instrument further comprises a first rotatable member configured to selectively synchronize the motion of the firing system with the motion of the articulation system and a second rotatable member operably engageable with the articulation system, wherein the closure system is configured to stop the rotation of the second rotatable member.

A reload assembly includes a shell housing, and a staple cartridge supported on a distal portion of the shell housing. The reload assembly further includes a pusher, a knife carrier supported, and a holder, each of which is supported within the annular cavity. The pusher is movable from a retracted position, through a partially advanced position, to a fully advanced position. The knife carrier includes at least one flexible arm having a free end. The at least one flexible arm has a hook portion on the free end. A housing of the holder defines at least one opening for receiving the hook portion of the at least one flexible arm of the knife carrier which is received within the at least one opening of the holder when the pusher is in the retracted position and is deflected from within the at least one opening when the pusher is in the partially advanced position.
