Disclosed herein are sealing devices configured for improving sealing functionality with an engaged extension member of an apparatus. More specifically, disclosed herein are trocar sealing devices configured for improving insufflation gas containment in relation to trocars (and/or other related type of devices) that are used for enabling a surgical instrument such, for example, a laparoscope, to gain access to an abdominal cavity (or other body cavity). By providing for such improved insufflation gas containment, sealing devices as disclosed herein are particularly advantageous, desirable and useful in view of long-standing reasons for limiting insufflation gas leakage and in view of newly recognized reasons stemming from outbreak of COVID-19 disease for limiting insufflation gas leakage.

A deformable seal for use together with a laparoscopic port has a deformable body with an upper region, a lower region, and a narrowed waist. A plurality of tool passing channels are individually formed in an axial direction through the deformable body, and each tool passing channel has a tool entrance on a surface of the upper region and a tool exit on a surface of the lower region. The tool passing channels are sufficiently elastic to conform to and seal about a shaft of a laparoscopic tool present in the channel and to close to inhibit leakage of an insufflation gases when the tool is removed from the tool passing channel.

An organ flush and drainage unit for limiting an increase of pressure within a cavity of an organ during liquid irrigation is disclosed. The unit comprises a drainage body enclosing a drainage zone in the form of a drainage chamber as encompassed within a unit wall. The unit also includes a coupling passage in the form of a mouth defined at the opened up end of the chamber. The unit further includes an instrument insertion aperture that is in alignment with the mouth and that is formed with a penetrable sealing means by being fitted with a membrane type penetrable resilient sealing member defining a central location of instrument penetration along which an organ working instrument which is sealably insertable and a drainage cum charging location in the form of a drainage cum charging stub extending from the chamber though the wall of the unit.

A device is disclosed that includes a bone stent positioned within a bony access channel formed within a vertebra. The bony access channel may extends from an outer end of the vertebra through an endplate. The device includes an end cap attached to a proximal end portion of the bone stent and is configured to, post-operatively, open to allow a reintroduction of a material to a spinal intradiscal space or intervertebral disc and to seal access to the spinal intradiscal space or the intervertebral disc after the reintroduction of the material.

A method of operating a surgical anchoring system can include inserting an outer sleeve of a surgical instrument at least partially into a first natural body lumen, the outer sleeve having a working channel. The method can include inserting a channel arm of the surgical instrument through the working channel of the outer sleeve and into a second natural body lumen. The channel arm has at least one first anchor member coupled thereto and a control actuator operatively coupled to the at least one first anchor member. The method can include expanding the at least one first anchor member from an unexpanded state to an expanded state to form an anchor point at a portion of the second natural body lumen. The method can include controlling, by the control actuator, a motion of the channel arm to selectively manipulate an organ associated with the first and second natural body lumens.

A valve assembly (1, 12, 21, 31, 44, 52, 60) includes a hollow tube (2). The valve assembly (1, 12, 21, 31, 44, 52, 60) also includes a first set of one or more valves (3) 5 arranged within the hollow tube (2). The first set of valves (3) is configured to permit sliding passage of a substantially cylindrical object (4). The valve assembly (1, 12, 21, 31, 44, 52, 60) also includes a second set of valves (5) arranged within the hollow tube (2) and spaced apart from the first set of valves to (3) define a chamber. The second set of valves (5) are configured to permit sliding passage of the cylindrical object (4). The 10 valve assembly (1, 12, 21, 31, 44, 52, 60) also includes one or more ultraviolet light sources (10) within the chamber (6) and/or a first port (13) connecting the chamber (6) to the exterior of the hollow tube (2) and configured for connection to a fluid flow path (14) for supply and/or extraction of fluid (19).

A valve component 1 of the invention comprises a main valve 2 which is located on a centre line and at least one auxiliary valve 3 which is located radially outwardly of the main valve 2. The main valve may be used for sealing engagement with a cannula. In some cases the cannula may be used for introduction of a number of robotically controlled surgical instruments generally, including a camera. The auxiliary valves 3 may be utilised to introduce another instrument through the valve component. The valve component is mounted in a manner which ensures that the valve component 1 is rotatable about a centre line through the axis of the valve component 1. This ensures that the valve component 1 can be rotated relative to a cannula inserted through the main valve 2 and consequently that the auxiliary valves 3 are rotatable relative to the cannula allowing the auxiliary valves 3 to be positioned to facilitate optimum access and manipulation for an auxiliary instrument(s) inserted through the auxiliary valve(s) 2.

A clot capture module can include a housing, a chamber inside the housing, a window, and a filter. The window permits visual inspection of a clot inside the chamber. The clot can access the chamber via an incoming flow path configured to direct blood from an aspiration catheter to an upstream surface of the filter. An aspiration control valve can block the flow of incoming aspirated blood until actuated to permit inflow of aspirated blood. An outgoing flow path can direct blood from a downstream surface of the filter to a remote vacuum canister.

A cannula for use in an access assembly includes an instrument valve housing including first and second housing sections and defining a cavity and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a seal assembly including an outer flange and a septum seal extending across the outer flange, a guard assembly disposed within the outer flange of the seal assembly, and a centering mechanism. The guard assembly includes a plurality of guard members. Each guard member of the plurality of guard members includes a ring portion and a flap portion. The flap portions of the guard members of the guard assembly are configured to engage and stretch the septum seal during reception of a surgical instrument through the valve assembly.
