An introducer cannula for use in crossing pleural layers includes an elongate tubular member and a pleural access liner. The elongate tubular member has a proximal end, a distal end, and a side wall that longitudinally extends between the proximal end and the distal end. The side wall has an outer surface and an inner surface, wherein the inner surface defines a lumen. The pleural access liner is made of a swellable and bioabsorbable material that swells when hydrated. The pleural access liner has a shape of an elongate tube and the pleural access liner has an elongate opening that surrounds an outer surface portion of the outer surface of the elongate tubular member.

The present invention relates to an assistive apparatus for a single port surgical robot, including a single port housing which forms a chamber communicating with a wound retractor and is coupled to the wound retractor with airtightness maintained, and a plurality of guide tubes which are provided in the single port housing to communicate with the chamber and form passages through which a surgical tool mounted on an arm of the single port surgical robot and assistive surgical tools for assisting with single port surgery are selectively inserted, wherein the plurality of guide tubes have different heights and are provided to protrude from the single port housing.

An apparatus for treating obesity in a human or animal mammal patient. The apparatus comprising a first volume filling device segment and a second volume filling device segment. The first and second volume filling device segments are adapted to be assembled into an implantable volume filling device of a controlled size. Each one of the first and second volume filling device segment comprises at least one interconnecting structure. The interconnecting structure of the second volume filling device segment is adapted to be formed fitted, such that the first and second volume filling device segment can be assembled into the volume filling device. The assembled volume filling device is adapted to be at least substantially invaginated by a stomach wall portion of a patient, with the outer surface of the device resting against the stomach wall, such that the volume of the food cavity is reduced in size.

In some embodiments an apparatus for providing access for a medical procedure in a patient's body cavity includes a stem configured for insertion through an opening in a body cavity wall. The stem has a bore and a cap is disposed at a proximal end thereof and includes an entry port in communication with the bore which receives an instrument to be inserted into the body cavity. An inflatable annular seal is disposed on the stem proximate the cap and a conduit extends through the cap providing pressurized gas at a first outlet in fluid communication with the body cavity providing insufflation pressure. A second outlet of the conduit is in fluid communication the seal, which when disposed inside the body cavity proximate the wall and inflated by pressurized gas, bears on an inner surface of the wall urging the cap into contact with an outer surface of the wall while sealing the opening.

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.

A safety isolation bag is a pneumoperitoneum device for intra-abdominal, endoscopic procedures, power morcellation and vaginal morcellation for facilitating safe removal of body mass from within the abdominal cavity. It comprises of an expandable and collapsible enclosed internal space (5) having a neck portion (4) with mouth (3) having retractor means (2) and provided with markings, colour coded indicating how much the bag is to be pulled out for the removal of large, medium and small tissue mass, and also having one or more non-return valves (6) attached with long looped threads (8) on one of the surface in the wall of the safety isolation bag below the neck as a means for introducing the surgical instruments and accessories into the enclosed internal space at the right place and to close the puncture hole after the procedure. It is made of one or more layers of flexible biocompatible/medical grade plastic film.

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 method includes receiving, from a primary pressure sensor, a pressure measurement indicative of a pressure of a patient cavity and controlling, by an insufflator, a supply of the insufflation fluid to the patient cavity based on the pressure measurement from the primary pressure sensor. The method further includes delivering, by a trocar, the supplied insufflation fluid to the patient cavity via an access port, wherein: the access port comprises a seal and a retractor; and the access port facilitates access therethrough to the patient cavity.

In an aspect of the invention there is provided an insufflator apparatus for exposing structures within a cavity of the human body for a diagnostic and/or therapeutic endoscopic procedure, comprising: an insufflation gas supply valve, adapted to provide insufflation gas to a pressure regulator; the pressure regulator, adapted to supply insufflation gas into the cavity of the human body via an input mechanism attachable to the human body, a means for determining a pressure level in the body cavity; an insufflator vent mechanism adapted to release excess insufflation gas volume returning from the pressure regulator; an insufflator controller arranged to real-time adapt an insufflation rate of said insufflation gas via said gas supply valve and vent mechanism at a set average pressure level in the body cavity in accordance with the means for determining the pressure level in the body cavity; and wherein the pressure regulator has a limited volume for temporarily storing a gas returning from the body cavity to thereby avoid transient pressure deviations from the set average pressure level in the body cavity, e.g. due to coughing or mechanical ventilation and s allowing the gas to return to the body cavity to maintain the set average pressure.

A view optimizing assembly, method and kit for use in combination with a laparoscope having a lens located on the shaft tip of the laparoscope, and a source of insufflation CO.sub.2. The invention includes a multi-lumen sheath assembly, a deflector assembly in fluid communication with the lumens of the sheath assembly, wherein the flow of CO.sub.2 through the lumens forms a vortex when coming into contact with the deflector assembly, thereby preventing fogging of the laparoscope lens.
