A surgical access device includes a cannula body, an anchor, and a first suture retention mechanism. The cannula body includes a housing and an elongated portion extending distally from the housing. The elongated portion defines a longitudinal axis and a channel extending therethrough. The anchor is disposed in mechanical cooperation with the elongated portion of the cannula body and is longitudinally translatable relative to the elongated portion. The first suture retention mechanism extends laterally from the anchor. A suture-receiving channel is defined between a portion of the suture retention mechanism and a portion of the anchor.

An obturator includes a unitary body having an elongate portion, a handle portion formed on a proximal portion of the elongate portion, and a piercing tip formed on a distal portion of the elongate portion. The obturator further includes a section of heat shrink tubing received about the handle portion of the unitary body. A method of assembling an obturator includes selecting an obturator body having a unitary structure and having a handle portion, placing a section of heat shrink tubing about the handle portion of the obturator body, heating the section of heat shrink tubing to shrink the tubing about the handle portion, and trimming the section of heat shrink tubing.

A surgical access device is disclosed and includes a housing, a cannula, a guide, and an expandable member. The cannula extends distally from the housing and defines a longitudinal axis. A wall of the cannula includes a first slot defined therein. The guide is engagable with the housing and defines a first channel. The first channel is disposed at a non-parallel angle relative to the longitudinal axis. The expandable member is disposed adjacent a distal portion of the cannula and is transitionable between a collapsed configuration and an expanded configuration. A first surgical instrument is insertable through the first channel of the guide and through the first slot of the cannula.

A cannula comprising a monolithic, flexible body having a central passageway bounded by a first flange and a second flange, the central passageway having an irregular shape and a diaphragm positioned therein, the first diaphragm having the same irregular shape and including at least one first diaphragm slit, and a second diaphragm positioned adjacent to or at one of the first or second flanges and having at least one second diaphragm slit.

A seal anchor member defines a housing defining a longitudinal axis, the housing having leading and trailing ends, and including a plurality of lumens extending between the leading and trailing ends, each lumen being adapted for substantially sealed reception of an object therein and defining a longitudinal axis, wherein at least two of the lumens define longitudinal axes that are non-parallel to facilitate angled, at-rest placement of multiple instruments within the seal anchor member.

A seal comprises a first sealing member and a second sealing member. The sealing members each have an accessway to facilitate access from one side of the sealing member to the other side of the sealing member. The accessways are offset to facilitate sealed access of an object through the sealing members.

A medical device to protect a body opening, the medical device including a sleeve having a proximal end and a distal end a proximal ring attached to the proximal end of the sleeve, and a guard assembly located a distal end of the sleeve.

A medical device for use during a gynecological procedure includes a main body, an attachment rim disposed at a first end of the main body, and a valve securing element disposed at a second end of the main body. A valve is disposed between the main body and the valve securing element.

Various devices and methods are provided with respect to inserting multiple surgical instruments through a single surgical access device. A medical device including a flexible tissue retractor a releasable insert having multiple instrument openings, and a member such as a sleeve is disclosed. The insert can be in the form of an insert assembly including multiple components. The sleeve can support the insert with respect to the retractor such that the insert and sleeve can be removed together with the retractor remaining in the incision. A method of using the insert is also described.

The present disclosure relates generally to the field of medical devices and establishing access to a target within the body, such as placing an access needle into a renal capsule into the human body. In particular, the present disclosure relates to devices and methods for performing a percutaneous nephrolithotomy (PCNL) procedure accurately and efficiently while minimizing exposure of the medical professional to harmful radiation.
