A septal closure and port device for implantation in the atrial septum of a patient's heart includes an expandable frame with a central portion defining a lumen, and first and second opposing end portions. The frame can expand and contract between a compressed, tubular configuration for delivery through the patient's vasculature and an expanded configuration in which the first and second end portions extend radially outwardly from the opposite ends of the central portion. The device can also have a valve member supported on the frame and positioned to block at least the flow of blood from the left atrium to the right atrium through the lumen of the frame. The valve member permits a medical instrument to be inserted through the lumen and into the left atrium, for performing a subsequent medical procedure in the left side of the heart.

Apparatus for placement in an incision of a natural body opening comprises a retractor having a sleeve (655, 656, 657) and a guard device comprising overlapping petals (662) depending from a mounting ring (661). The guard device is movable by the retractor from an insertion configuration to a deployed configuration as the retractor sleeve is moved to the retracting configuration.

Method and apparatuses for providing access to a body cavity of a living animal through an access port inserted in an incision made in a wall of the body cavity are disclosed. In some embodiments, the apparatus includes a cap configured to attach to the access port, the cap including an opening configured to permit insertion of a medical instrument through the cap and access port into the body cavity, and a tubular sleeve including a distal end sealingly connected at the opening and extending outwardly therefrom, the sleeve including a proximal end configured to receive and provide a seal with the medical instrument when received. The apparatus also includes a closure disposed to temporarily seal the sleeve prior to insertion of the medical instrument through the opening in the cap.

Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The distal end of the sheath is maintained in the first, low cross-sectional configuration and expanded using a radial dilatation device. In an exemplary application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as ureteroscopy or stone removal.

A tubular retractor securement frame is disclosed including a mounting bracket, two flexor arms, and a device emplacement oriented to receive and hold in-place a surgical tool. The mounting bracket includes an elastically deformable plate, rails extending about orthogonal from the elastically deformable plate and about parallel to one another, and receptacles facing one another in the rails which are arranged to receive a retractor arm extending from a tubular retractor at a fixed angle. The flexor arms extend from the mounting bracket adjacent to the rails. The flexor arms are positioned so as not to occlude visualization through the tubular retractor and such that applying pressure to flex the flexor arms toward one another shifts the rails to accept or remove the retractor arm into or from the receptacles, and releasing the pressure reverts the rails so as to inhibit the retractor arm from being inserted or removed.

A multi-functional soft tissue wound protective sleeve includes: a waste collection bag including a bottom patch and a surface patch connected to form a cavity; a bottom ring to be inserted into a human body, to push away human tissues surrounding the bottom ring to form a surgery space; a flip ring located above the waste collection bag and having an adjustable distance with the bottom ring, to prevent waste from touching a surgical surface; a medical inner membrane connecting the bottom ring to the flip ring and defining a surgery channel to the surgery space; a positioning ring sealed with a hole edge of the surgery through-hole on the bottom patch; and a medical outer membrane connecting the positioning ring to the flip ring so as to guide waste escaping the surgery channel over the flip ring to flow into the waste collection bag.

A medical device of the present invention includes one or more anchors and an elongated member. Advantageously, the elongated member may be coupled to the anchors. The elongated member and anchors are configured to generate a force on a mesentery. The force is sufficient to retract a bowel of the patient into an upper portion of an abdominal cavity of the patient. When the patient is in a slightly angled position, the weight of the medical device pulls the mesentery into the upper abdomen. Since the bowel is connected to the mesentery, the device also indirectly pulls up the bowel. In some implementations of the device, a slight angle may be unnecessary. In others, the device may also inversely retract the mesentery and attached organs into the lower abdomen to facilitate surgical access to the upper abdomen. In some implementations of the device, a slight angle may be unnecessary.

An apparatus for opening or closing a tissue opening in a biological subject, the apparatus including at least two flexible arms coupled to a tissue surface in use, each arm being curved outwardly in a mid-portion to accommodate a tissue opening therebetween and a biasing mechanism that selectively biases opposing ends of each arm to thereby at least one of bias mid-portions of the arms apart to assist in at least partially opening the tissue opening; and bias mid-portions of the arms towards each other to assist in at least partially closing the tissue opening.

The invention comprises an apparatus for covering an exposed end of a severed sternum, comprising a strip operative to cover the exposed end and pliable portions which are able to be manually deformed over sides of the exposed end so as to retain the strip against the exposed end to stop or at least reduce flow of blood from the exposed end.

Several methods to reduce surgical site infections include inserting a surgical access device into an incision, retracting tissue, and introducing fluid into the surgical access device such that the fluid exits the surgical access device and irrigates a surgical site. Other methods do not include introducing fluid into a surgical access device but include suctioning a fluid into the surgical access device and removing the fluid from the body.
