A neurosurgical apparatus includes a guide device and a neurosurgical instrument is disclosed. The guide device includes a tube for insertion into the brain and a head attached to the proximal end of the tube for affixing the guide device to a hole formed in the skull. The head has a passageway therethrough in communication with the bore of the tube such that the bore of the tube and the passageway through the head define an internal channel through which a neurosurgical instrument can be passed into the brain of the subject. The neurosurgical instrument is for insertion to a desired brain target through the internal channel of the guide device. The apparatus includes one or more sealing elements for providing a fluid tight seal between the internal channel of the guide device and the exterior of the neurosurgical instrument to prevent fluid leakage from guide tube.

A valved introducer sheath (1) having a valve housing (17, 18) with a through-lumen and an inflatable cuff (2, 60, 70) disposed in the valve housing that can be inflated to occlude the through-lumen, is described. The device has an overflow tube (30) in fluidic connection with the inflatable cuff having a resiliently deformable overflow chamber (34). When the inflatable cuff is filled with inflation liquid, the cuff partly or fully occludes the through-lumen, thereby preventing blood pass through the lumen. When an interventional device is pushed through the lumen for use in a medical procedure, the pressure forces liquid from the cuff into the overflow tube, allowing the cuff to partly deflate. As the overflow chamber is resiliently deformable, the liquid is pressurised which maintains a seal between the inflatable cuff and the interventional device. Upon removal of the interventional device from the lumen, the overflow tube pushes fluid back into the cuff, allowing it to reinflate fully.

A system and method for a modular external interface for a skin penetrating appliance is provided. The modular device prevents internalization of bacteria, other infectious agents, or other unwanted materials from entering the access point for a catheter, Steinman pin, Kirschner wires, or other percutaneous instruments. The modular external interface provides for the hermaticity in the vicinity of the skin-appliance interface with fluid exudate or transudate egressing from the vicinity of the skin-appliance interface. The modular external interface forms a hermetic seal with the external neck of an implanted appliance with a locking feature that joins the main body of the modular external interface together around the neck of the appliance. The modular external interface provides mechanical stability to an implanted appliance so as to speed healing around a semi-permanent implanted appliance, as well as connection points for vacuum lines and drive lines for the insertion of medical devices.

The present invention relates to surgical access devices (or surgical access ports) and related methods. More particularly, the present invention relates to such devices that are advantageously adapted for use in single-incision laparoscopic surgical (“SILS”) procedures The present invention also relates to kits and methods involving such surgical access devices.

A length adjustable cannula includes: a pipe-like main body having a through hole formed therein and an outer circumferential surface on which a screw thread is formed; a base grip provided at an end of the main body; an inner support plate provided at another end of the main body; and an outer support plate thread-coupled with the outer circumferential surface of the main body, the outer support plate being movable along the screw thread in a lengthwise direction of the main body. A position of the outer support plate is adjusted based on a distance from an outside skin to a medical treatment region of a human body, such that the outer support plate is brought into contact with the outside skin and the inner support plate is brought into contact with and supported by an inside skin of the human body.

An apparatus for guiding cannulation with a dialysis needle of an arteriovenous dialysis access graft subcutaneously implanted in a body of a subject. The guiding apparatus comprises an elongated body member comprising a base portion terminating in longitudinal edges, a distance between the longitudinal edges of the base portion being substantially equal to a lateral dimension of the aces graft, and an elongated tubular sleeve defining an pocket having a longitudinal dimension and a lateral dimension configured to receive the body member. The body member is adapted to be received in the pocket of the sleeve for securing adjacent the subcutaneous access graft such that the inner surface of the base portion is aligned with a cannulation point of the graft for guiding location of a needle insertion.

An example introducer is disclosed. An example introducer sheath includes a tubular member including an inner surface, an outer surface and a wall extending therebetween. The introducer further includes a plurality of spine members. The plurality of spine members are positioned radially inward of the outer surface of the tubular member. Further, each of the plurality of the spine members are positioned radially outward of the inner surface of the tubular member. Additionally, the tubular member is designed to shift from a first configuration to a second configuration and the wall has a first thickness in the first position and a second thickness in the second position, the second thickness smaller than the first thickness.

An implantable device includes a low-profile housing having a cavity defined in a side thereof, and an element insertably removable with respect to the housing in a direction substantially parallel to a surgical plane of the implantable device. The element has a first portion adapted to be received in the housing cavity. The element further includes a second portion adapted to protrude from the housing upon insertion of the element into the housing cavity. The second portion includes at least one surface adapted for engagement with a surgical instrument for insertion and removal of the element with respect to the housing. A method for servicing the implantable device includes, at an incision proximate an implant location of the implantable device, insertably and removably accessing the element in a direction substantially parallel to a surgical plane of the implantable device.

A smoke evacuating tissue guard includes a tubular body defining a longitudinally-extending passageway, a collar coupled to a proximal end portion of the tubular body, and an outlet coupled to the collar and in fluid communication with an annular channel defined through the collar. Upon application of suction through the smoke evacuating tissue guard, the smoke evacuating tissue guard establishes a fluid path extending from the passageway of the tubular body and into the annular channel of the collar via an annular gap defined between the tubular body and the collar.

A connection unit for air feeding tube is a connection unit to which an air feeding tube is connectable and fixable and which includes: a first pipe having an opening through which gas from the air feeding tube flows in; a second pipe that is configured to be arrangeable substantially parallel to a surface of a bed used in an examination, and includes an opening through which the gas flows out; and an air feeding flow path which is formed to include the two openings and through which the gas is fed. When the air feeding tube is fixed to the connection unit for air feeding tube and is used, a part of the air feeding flow path for the gas is formed so as to pass through an area located at a position opposite to a gravitational direction with respect to a central axis of the second pipe.
