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 device for creating an intercostal transcutaneous access to an, in particular endoscopic, operating field including a base body, which closely surrounds an incision all-side frame-shaped and with at least two webs mounted on the base body, which can be introduced into an intercostal space, by which two ribs arranged next to each other can be moved apart. To create a device for creating an intercostal transcutaneous access to an, in particular endoscopic, operating field which allows individual pressing apart of the ribs, it is proposed according to the invention that the at least two webs are mounted adjustable relative to each other on the base body.

A surgical access device including a housing having a nozzle assembly, a gas supply plenum, a gas return plenum, and a pressure sensing plenum, as well as an elongated tubular body that extends from the housing portion and defines a central lumen communicating with the nozzle assembly and the gas return plenum, a telescopic cannula assembly associated with the tubular body and including a proximal section arranged coaxially within the tubular body and a distal section coaxially supported within the proximal section and mounted for movement relative to the proximal section between retracted and extended positions, and an elastomeric sheath associated with the telescopic cannula assembly and having a distal anchor portion for securing the surgical access device during a laparoscopic surgical procedure.

Meniscal repair devices, systems, and methods are provided.

The invention relates to a trocar sleeve or trocar and a trocar tip for minimally invasive/endoscopic surgical procedures carried out on people or animals. The trocar sleeve here has holding means in order to prevent the device from slipping out during the operation.

Cannula devices, systems, and methods are provided for introducing one or more instruments into a patient's body to perform a procedure. In one example, the cannula device includes first and second housings defining a throughbore, and a plurality of elongate members extending distally from the housings, the elongate members cooperatively defining a passage axially aligned with the throughbore between proximal ends and distal tips of the elongate members. The first housing is moveable in an axial direction with respect to the second housing to cause the proximal ends of the elongate members to move outwardly to increase a size of the passage and, optionally, may taper when expanded. Optionally, one or more secondary devices, e.g., an obturator with a sharpened tip, or an obturator and tubular access device may be provided that may be inserted through the throughbore into the passage before expansion of the passage.

An endoscope and methods of use thereof is provided with at least one multi-functional, multi-directional arm supporting a plurality of imaging, lighting and other sensory elements. The multi-functional arms provide a mounting platform upon which cameras, lights and sensors may be mounted to generate multiple-angled images and video, arena-like lighting and other data relevant to performing a diagnostic or MIS procedure. The multi-directional arms may be inserted through a single portal in the endoscope and deployed in multiple directions from a single portal once inserted into a body cavity. The pitch, roll, length and curvature of each of the extending arms may be individually or jointly adjusted to create a customized view of an internal space during an endoscopic procedure. The extending arms may also include communication elements to wirelessly transmit the images and other data generated by the sensory elements to a remote computing and display device.

A surgical system includes an external anchor, an internal anchor and an instrument. The external anchor is adapted to be positioned outside a body. The internal anchor is adapted to be inserted into the body via a single entrance port, positioned inside the body and magnetically coupled with the external anchor. The instrument is adapted to be inserted into the body via the single entrance port and secured to the internal anchor. The instrument includes an end-effector that has multiple degrees of movement via multiple axes.

An apparatus comprising: a sheath comprising a plurality of openings at a distal end; an elongate first needle extendible perpendicularly from said sheath through one of said plurality of openings; and an assembly comprising at least two second needles arranged in a predetermined pattern relative to said first needle, and extendible perpendicularly from said sheath, wherein, when extended from said distal end of said sheath: (i) each of said second needles extends a different length from said distal end of said sheath, (ii) at least a distal portion of each of said second needles is resiliently biased to extend laterally outwardly in relation to said first needle, and (iii) a lateral spread region defined by said distal portions of all of said second needles is determined based, at least in part, on a distance of said extending from said distal end of said sheath.

Some embodiments of a medical system include a subcutaneous anchor device that extends outwardly from side wall of an intravenous cannula so as to secure the intravenous cannula in a position relative to a skin penetration point.
