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 instrument includes a handle, a trocar in communication with the handle, and a cannula in communication with the trocar and the handle. The cannula is engaged (locked) with the handle when linearly displaced proximally towards the handle and, the cannula is disengaged (unlocked) from the handle when linearly displaced distally away from the handle. The cannula is linearly reciprocated, between the locked position and the unlocked position, along a linear travel path defined parallel to a longitudinal axis of the trocar such that the cannula is prohibited and permitted to articulate about the longitudinal axis of the trocar, and relative to the handle, respectively. Advantageously, the cannula is locked and unlocked from the trocar by without requiring an external force exerted generally transverse to trocar and/or cannula—thereby permitting a user to lock/unlock the cannula, relative to the trocar, with one hand.

An apparatus for the treatment of acid reflux disease comprising two or more movement restriction device segments adapted to be assembled movement restriction device of a controlled size. The assembled movement restriction device can at least partly be invaginated by a patient's stomach fundus wall. A substantial part of the outer surface of the movement restriction device is adapted to rest against the stomach wall without injuring the latter in a position between the patient's diaphragm and at least a portion of the lower part of the invaginated stomach fundus wall, such that movement of the cardiac notch of the patient's stomach towards the patient's diaphragm is restricted, to thereby prevent the cardia from sliding through the patient's diaphragm opening into the patient's thorax, so as to maintain the supporting pressure against the patient's cardia sphincter muscle exerted from the patient's abdomen.

A surgical port includes a first end, a second end opposite the first end, and a longitudinal axis extending through the first end and the second end. An outer sidewall extends between the first end and the second end. First and second channels extend through the port from the first end to the second end. A first electrically conductive portion extends from the first channel to the outer sidewall, and a second electrically conductive portion extends from the second channel to the outer sidewall. The first electrically conductive portion provides a first electrically conductive path between the first channel and the outer sidewall and the second electrically conductive portion provides a second electrically conductive path the second channel and the outer sidewall. The second electrically conductive path is separate from the first electrically conductive path. Devices and methods relate to surgical ports.

A cannula assembly for use in robotic surgery is disclosed that includes a robotic cannula having a housing with an open end and a tubular portion extending distally from the housing, the tubular portion being dimensioned to accommodate passage of a surgical instrument having a 12 mm diameter, an adapter assembly configured for engagement within the open end of the cannula housing and including a tubular body with a passage supporting a primary seal dimensioned to accommodate passage of a surgical instrument having a 12 mm diameter, and an insert tube dimensioned to extend through the passage of the body portion of the adapter assembly and the tubular portion of the robotic cannula, the insert tube including a head portion with a passage supporting a secondary seal dimensioned to accommodate a surgical instrument having an 8 mm diameter.

A tissue retrieval system including a tissue retrieval bag deployable from an introducer and suspended in an open configuration by support arms can include retention features to prevent inadvertent movement of the tissue retrieval bag relative to the support arms. The support arms can include protruding domes, folds, or curls to restrict sliding of the tissue retrieval bag relative to the support arms. Alternately, tension can be maintained in a cord loop coupled to an opening of the tissue retrieval bag to prevent the tissue retrieval bag from inadvertently sliding relative to the support arms.

Disclosed herein are sealing devices configured for improving sealing functionality with an engaged extension member of an apparatus. More specifically, disclosed herein are trocar sealing devices configured for improving insufflation gas containment in relation to trocars (and/or other related type of devices) that are used for enabling a surgical instrument such, for example, a laparoscope, to gain access to an abdominal cavity (or other body cavity). By providing for such improved insufflation gas containment, sealing devices as disclosed herein are particularly advantageous, desirable and useful in view of long-standing reasons for limiting insufflation gas leakage and in view of newly recognized reasons stemming from outbreak of COVID-19 disease for limiting insufflation gas leakage.

Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants.

A system for preventing relative motion between bones or sections of bone, for example, an ilium and a sacrum. The system includes an insertion tool and an implant. The implant includes a trunk, a distal anchor, a proximal anchor, and a stem coupled to the trunk. A driver of the insertion tool receives an input for a drive shaft of the insertion tool to draw the stem proximally such that the trunk is drawn towards the insertion tool. The drawing of the trunk and engagement of first and second engagement features is configured to deploy the proximal anchor outwardly. The distal anchor may be an expandable member, and the implant may define a bore extending through the proximal anchor for the distal anchor to receive injectable material. The system may be cannulated such that the insertion tool and the implant may be directed over a guidewire to position the implant.

A system may comprise a first catheter having a first steerable segment and a second catheter disposed within the first catheter. The second catheter may have a second steerable segment. The system may also comprise an imaging element supported at a distal end of the second catheter, a coil reference sensor supported at a distal portion of the second catheter, and a processor in electrical communication with the coil reference sensor. The processor may be configured to determine a position of a distal portion of the first catheter with reference to the coil reference sensor.
