A method of adjusting a switch of a device, which comprises using a biasing force-adjusting element, adjusting a magnitude of a biasing force imparted to a switching element of the switch by a biasing element disposed about the switching element, wherein the switching element is movably disposed within an interior cavity of a hollow body of the switch and the biasing force places the switching element in one of a first position and a second position. The first position corresponds to a first electrical state and the second position corresponds to a second electrical state.

Surgical stapling systems

A system is disclosed. The system can comprise a replaceable staple cartridge comprising a plurality of staples, a proximal laterally-protruding lug, and a distal laterally-protruding lug. The system can further comprise a channel configured to receive the replaceable staple cartridge, wherein the channel comprises a sidewall comprising a proximal receptacle positioned and dimensioned to receive the proximal laterally-protruding lug and a distal receptacle positioned and dimensioned to receive the distal laterally-protruding lug.

A fluid management system includes a pump connectable to a fluid source. An inflow line removably connects to a cannula for delivering a fluid flow from the pump into a surgical site, such as a joint cavity. A flow pressure sensor is coupled to measure flow pressure in the inflow line and produce a measured pressure value, A controller is connected to the pump and the flow pressure sensor, and the controller maintains a pressure set point by controlling a pump speed based on a backpressure-adjusted pressure value calculated by subtracting a backpressure value selected from a backpressure table from the measured pressure value. The BAPV is monitored to determine whether the BAPV deviates outside an initial BAPV range, and corrective measure are taken should such deviations occur.

Catheter system, devices and methods for diagnosing and treating lateral stenosis causing back pain and or leg pain. The devices comprise a tubular part for insertion into a working cannula to self-position itself safely within the foramen, and minimize the risk of displacement medially or laterally, to prevent nerve or dura injury. An expandable membrane is configured to maintain the catheter device within the foramen. Expansion of this membrane would decompress the nerve within the foramen by opening the foraminal canal as the membrane expands.

Surgical stapling systems

A system is disclosed. The system can comprise an end effector configured to receive a compatible replaceable staple cartridge, wherein the end effector comprises a first outer surface, and wherein a classifying identification of the end effector is inscribed on the first outer surface. The system can also comprise the compatible replaceable staple cartridge comprising a second outer surface, wherein a classifying identification of the compatible replaceable staple cartridge is inscribed on the second outer surface. The classifying identification of the compatible replaceable staple cartridge can correspond to the classifying identification of the end effector.

Surgical staples having compressible or crushable members for securing tissue therein and stapling instruments for deploying the same

A staple having a crown, a deformable leg extending from the crown, and a spring extending from the crown configured to compress tissue between the spring and the deformable member. Owing to the flexibility of the spring, the staple can accommodate a wide range of tissue thicknesses while still compressing the tissue captured therein. As a result, a single staple design can be used in a wide variety of surgical procedures thereby reducing the amount of staple designs that must be provided to the surgeon. In at least one embodiment, the staple includes a crushable member. This crushable member can include a plastically deformable first portion and an elastically deformable second portion. The present invention can also include, in various embodiments, a crown, a first deformable member extending from the crown, and means for compressing the tissue against the first deformable member.

PRESSURE RELIEF FOR A CATHETER BALLOON DEVICE

A method of limiting an inflation system pressure for dilating a region of a patient’s nasal sinus passageways. The method includes grasping an inflation device. The inflation device includes a syringe including a plunger slidably disposed within a barrel, a connector for fluidly connecting an outlet of the syringe with a surgical instrument balloon, and a mechanical pressure indicator associated with the syringe, the mechanical pressure indicator including a housing and an indicator body disposed within the housing. The method also includes delivering the surgical instrument balloon to a patient’s paranasal sinus target area, operating the plunger within the barrel of the syringe to deliver pressurized fluid to the surgical instrument balloon, and transitioning the indicator body to extend outside of the housing when a predetermined inflation pressure of the surgical instrument balloon is reached.

Surgical stapling systems

A system for stapling tissue is disclosed. The system can include a channel and a compatible staple cartridge comprising a plurality of staples. The channel and the compatible staple cartridge comprise mating or cooperating alignment features for permitting complete insertion of the compatible staple cartridge and for preventing an incompatible staple cartridge from being completely inserted in the channel.

Ultrasonic surgical instrument

A surgical instrument includes a housing, an end effector including a clamp jaw, a drive member extending distally from the housing, and a clamp lever pivotably coupled to the housing. The drive member is operably coupled to the clamp jaw such that translation of the drive member pivots the clamp jaw from an open position towards a clamping position. The clamp lever is operably coupled to the drive member via a rigid slider. The clamp jaw is configured to provide a jaw force to clamped tissue, measured at about 0.192 inches from a distal end of the clamp jaw, of from about 1 lbf to about 8 lbf in response to a full actuation of the clamp lever.

Retraction systems, assemblies, and devices

Retraction systems, assemblies, and devices for retracting an end unit are provided. A retraction assembly may be configured to move the end unit of a robot between a first state and a second state. A first signal may be received indicating a working condition. A first instruction may be generated to move the end unit from the second state to the first state. The retraction assembly may be caused to move the end unit from the second state to the first state based on receiving the first signal and the first instruction. The end unit may be held in the first state when the first signal is being received and the retraction assembly may move the end unit from the first state to the second state when the first signal is not received.
