摘要： An injection port includes a port body having a fluid reservoir and a connector in fluid communication with the reservoir. The injection port further includes a conduit protection feature that is configured to protect against kinking of the conduit, decoupling of the conduit from the connector, or penetration of the conduit by a needle. The protection feature may include an anchor for anchoring the conduit to tissue to reduce conduit movement. The protection feature may include a recess that is configured to receive part of the conduit. The protection feature may include a bend formed in the connector to reduce transverse stresses in the conduit. The protection feature may include a bell-shaped shroud encompassing the connector. A sleeve may further protect the conduit and/or the coupling between the connector and the conduit.

摘要： A roll-up wound protector has a distal ring, a proximal ring, and a flexible sleeve extending between the proximal and distal rings. The proximal ring is rollable to gather the flexible sleeve around the proximal ring and shorten the length of the flexible sleeve. The cross-sectional geometry of the proximal ring may be generally s-shaped. The cross-sectional geometry may be asymmetric about the longitudinal axis and asymmetric about the lateral axis. The height along the longitudinal axis may be greater than the width along the lateral axis. The proximal ring may comprise a medial surface having a circumferential recess and a lateral surface having a circumferential recess, the two recesses being longitudinally staggered relative one another.

摘要： A laparoscopic disk assembly for a Hand Assisted Laparoscopic Surgery (HALS) procedure includes an exteriorly visible laparoscopic disk (seal cap) attached to a retractor skirt. The laparoscopic disk provides an adjustable exterior opening. A downward annular surface is supported by an attached flexible or resilient (“soft) support member that in turn forms an annular contact upon a patient's abdomen wall surrounding an incision to form a sealing connection, to facilitate improved manipulation or degrees of freedom through the laparoscopic disk without loss of insufflation pressure, to minimize, if not eliminate, bruising, to prevent rotation movement of a retractor skirt in the incision, and to reduce fatigue. Versions include a resilient pad, a resilient skirt that adheres to the patient's skin, a skirt with horizontal pleats, and a toroidal bladder that comfortably depresses into the skin.

摘要： A biopsy device includes a needle extending distally from a body. The needle includes a transverse aperture, a first lumen, and a second lumen. A cutter is movable within the first lumen to sever tissue protruding through the transverse aperture. A valve assembly is operable to change the pneumatic state of the second lumen. The valve assembly includes a valve body and a translating member slidably disposed in a bore of the valve body. The valve body includes a first port and a second port. The first port is in fluid communication with the second lumen of the needle. The second port is in fluid communication with atmospheric air. The translating member selectively couples the first port with the second port based on the longitudinal position of the translating member within the bore. The translating member translates relative to the valve body based on the position of the cutter.

摘要： A seal assembly for permitting hand assisted laparoscopic procedures includes a seal cap having a seal positioned within a housing. The housing includes a lower seal ring having a track which supports an upper seal ring for relative rotational motion, wherein the seal is supported between the upper seal ring and the lower seal ring for rotation between an open orientation and a closed orientation. The track includes an inner upstanding annular wall and an outer upstanding annular wall connected by a base member. A ratchet mechanism controls motion of the upper seal ring relative to the lower seal ring. The ratchet mechanism includes a ratchet arm oriented to engage a ratchet surface. The ratchet surface extends outwardly from a center of the seal assembly.
