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 vascular access device with vessel accommodation includes a top portion and a bottom portion. The top portion includes a top vascular housing for encasing a top portion of a vessel when implanted and at least one hollow male member extending from the top vascular housing. The bottom portion includes a bottom vascular housing for encasing a bottom portion of the vessel when implanted and at least one female member disposed at an upward-facing coupling edge of the bottom vascular housing. The at least one female member receives the at least one hollow male member of the top portion to couple the top portion and the bottom portion together such that the top and bottom portions can move vertically with respect to one another but rotation and movement in the horizontal/longitudinal directions are inhibited.

Disclosed is an implantable medical port and methods of using the implantable medical port to deliver and/or to withdraw a desired agent, such as medicines, treatments, or any other fluid into and/or from a body of a subject. The implantable medical port includes two or more needle-penetrable septum portions to provide an increased needle penetration area. Also provided is an implantable medical port having a fluid cavity the contains a substantially needle-impenetrable member that prevents a needle from inadvertently puncturing or otherwise damaging a septum portion other than the septum portion that was initially punctured to gain access to the fluid cavity.

A vascular access port has a single unitary septum, included in an upper wall of the port body. The septum has an arched or curved portion extending at least partially down a side of the port body opposite the outlet port and covering the lateral access zone or straight-line-access aperture to the outlet port/aperture.
