An illuminating ring assembly is disclosed. The illuminating ring configured to be used with a surgical access element. The illuminating ring assembly comprises a housing defined by a cover and a wall member extending from the cover, wherein the cover and wall member cooperate to define a cavity therein, a light element configured to be disposed with the cavity, and an attachment mechanism configured to selectively attach the housing to a surgical access element. Wherein the cover and the light element both include an opening therethrough.

A steerable transseptal punch system and method of using the steerable transseptal punch system to access the left atrium.

Disclosed herein are multiple cannulas defining a lumen sized and dimensioned to receive one or more medical instruments, an inflatable outer membrane attached to an outer surface of the cannula, and at least one activator that reversibly pressurizes a fluid contained in the outer membrane to fill or pressurize the outer membrane.

A device for pacemaker lead placement is disclosed. The device has a device tip having a tissue bite area, ferrule holders, and needle tips. The device also has a lead end rest at the distal end, with a pacemaker lead end situated on the lead end rest, the pacemaker lead end having first and second anchor suture holes. The device further has an anchor suture with ferrules at respective ends of the anchor suture, wherein the ferrules of the anchor suture are passed through the anchor suture holes and into communication with the ferrule holders. The device further has one or more tube guides configured to organize and manage sutures during a minimally invasive surgical procedure.

An access device for a minimally invasive procedure can include a port body defining an instrument channel for a medical instrument, a radial extension extending at least partially outward from the body in a radial direction. The radial extension can extend from a distal end of the port body. The radial extension can define an imaging device cavity defined therein spaced from the port body and opening distally from the radial extension. The imaging device cavity can be configured to receive an imaging device therein for providing images within a field of view that is at least partially distal of the port body.

A craniocerebral operation passage is provided, including a guide device, a trocar, and an outer sheath. The guide device is used for penetrating into the brain of a patient; a connection hole is provided in the middle of the trocar and passes through the trocar in a direction of a central axis of the trocar; the connection hole and the trocar are coaxially disposed; the trocar can sheathe on a periphery of the guide device through the connection hole and can slide in a lengthwise direction of the guide device; the outer sheath is internally hollow for providing an operation passage; and the outer sheath can sheathe the periphery of the trocar. The craniocerebral operation passage is accurately located and can effectively protect brain tissues of a patient.

Disclosed is a surgical instrument with a handle and elongate shaft assembly extending distally from the handle. The elongate shaft assembly has a longitudinal axis and is able to articulate between a fully flexed configuration and a lesser flexed configuration. The elongated shaft assembly includes a first tubular member having a first flexible portion with a first preferential bending direction. The elongated shaft assembly also includes a second member including a second flexible portion axially fixed to the first tubular member at a position distal from the first flexible portion. The first flexible portion is defined by a plurality of cutouts, each cutout defining a cutout longitudinal axis transverse the shaft longitudinal axis and wherein the plurality of radial cutouts have an asymmetrical shape about the cutout longitudinal axis.

A surgical access device is insertable into tissue and includes a housing and a tubular member extending from the housing. A balloon is attached to an outer surface of the tubular member. The balloon has an outer surface with a plurality of depressions thereon. The plurality of depressions is arranged such that a portion of the balloon has a contact patch with an area that is less than an area of tissue surrounding the contact patch. The contact patch of the balloon has surface area that is greater than the area of tissue surrounding the contact patch of the balloon.

A handheld body cavity access device includes a handle having a distal end, a proximal end, a longitudinal axis, and a cavity. A dilator assembly has a proximal end coupled to the handle and a distal end. A blade assembly is at least partially disposed within the dilator assembly and has a proximal end, a distal end, and a blade hub coupled to the proximal end and disposed in the cavity of the handle. The dilator assembly is movable axially between a retracted position, in which a distal end of the blade assembly extends from the distal end of the dilator assembly, and an extended position, in which the distal end of the blade assembly is covered by the distal end of the dilator assembly. The blade hub includes a body defining a bore aligned with the longitudinal axis and a tab extending away from the longitudinal axis.

A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be introduced over the first, advanced along a second longitudinal axis parallel to but offset from the first. A third dilator tube may be introduced over the second, advanced along a third longitudinal axis parallel to but offset from both the first and the second. An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.
