An end effector assembly of a tissue-resecting device includes an outer shaft, a drive wire, the distal cutting tip, a hub housing, and a driver. The outer shaft includes a distal end portion defining a window therethrough. The drive wire extends through the outer shaft. The distal cutting tip is disposed within the outer shaft and engaged with the distal end portion of the drive wire. The distal cutting tip at least partially overlaps the window. The hub housing is engaged with the proximal end portion of the outer shaft. The driver is disposed within the hub housing and engaged with the proximal end portion of the drive wire to driver rotation of the drive wire and distal cutting tip within and relative to the outer shaft. The driver defines an internal lumen and at least one lateral opening disposed in communication with the internal lumen. An outflow path is defined from the window through the outer shaft and about the drive wire, into an interior of the hub housing, through the at least one lateral opening, and through the internal lumen.

A tissue resecting instrument includes a drive assembly coupled to an inner cutting shaft and configured to drive translation and/or rotation of the inner cutting shaft, a trigger coupled to the drive assembly and configured for manual actuation to drive the drive assembly, a vacuum generator configured to generate vacuum to suction cut tissue through the inner cutting shaft and into the vacuum generator, and a tissue collection cartridge configured to engage the housing. The tissue collection cartridge defines a port configured to communicate with the vacuum generator such that the vacuum generator urges cut tissue from the vacuum generator through the port into the tissue collection cartridge. An auxiliary vacuum source is configured to selectively provide additional vacuum to increase suctioning of cut tissue through the inner cutting shaft and into the vacuum generator.

The present invention relates to a power-assisted liposuction device. The power-assisted liposuction device includes: a handpiece; a motor mounted inside the handpiece and connected with a power source to provide driving force; a reverse cam of which one end is connected to the motor; and a cannula connected to the other end of the reverse cam. The reverse cam converts a rotary motion of the motor into a linear reciprocating motion so that the cannula performs a reciprocating motion when the motor is operated.

A surgical instrument system is disclosed which comprises a control screen usable to control the surgical instrument system in real time.

A tissue expander having a shell, an opening in the shell in communication with an external vacuum source to apply a vacuum within the shell and impart a distracting force to expand tissue, and a rim connected to the shell and adapted to be in contact with a skin of a patient. The rim is non-fixedly attached to the skin of the patient and moves laterally outwardly with respect to the shell under application of the vacuum.

An apparatus for treating obesity of a patient having a stomach with a food cavity. The apparatus comprising a volume filling device adapted to be at least substantially invaginated by a stomach wall portion of the patient with the outer surface of the volume filling device resting against the stomach wall, such that the volume of the food cavity is reduced in size by a volume substantially exceeding the volume of the volume filling device. The apparatus further comprises at least one adjustable stretching device adapted to be at least substantially invaginated by a stomach wall portion of the patient with the outer surface of the stretching device resting against the stomach wall and adapted to stretch a portion of stomach wall, and a fluid connection device interconnecting the volume filling device and the stretching device.

A medical system includes a flexible catheter, an imaging probe, a working catheter, and a positioning system. The flexible catheter includes a plurality of first lumens and a sealing device having one or more balloons to seal the anatomic passageways at a sealing location and one or more flaps or valves to remove air from the anatomic passageways. The imaging probe and working catheter are receivable within the plurality of first lumens and extend through the sealing device. The working catheter includes one or more second lumens to receive a medical instrument. The positioning system is configured to determine a position of a distal portion of the flexible catheter, the imaging probe, or the working catheter. The medical system is configured to collapse a portion of the anatomic passageways distal of the sealing location by removing air from the anatomic passageways to facilitate ultrasound imaging using the imaging probe.

A single integrated intravascular device including a stentriever and semi-compliant balloon housed therein. After traversing a clot, the device is deployed to a self-expanded state engaging the clot therein, whereupon the device along with the embedded clot is removed. Detecting through imaging a stenosis at an original position of the captured clot, the device is reintroduced to that location and the stentriever is deployed to a self-expanded state. Inflating the semi-compliant balloon enlarges the stentriever to a hyper-expanded state greater than the self-expanded state thereby dilating the vessel while simultaneously completely detaching/releasing the stentriever from a remaining portion of the device. Then the semi-compliant balloon is collapsed and withdrawn along with the remaining portion of the device, while the detachable/releasable portion of the stentriever in the self-expanded state remains in the vessel.

The present invention relates to a reflux disease treatment apparatus, comprising an implantable movement restriction device with an elongated shape that maintains cardia in the correct position and an implantable stimulation device adapted to engage with the cardia sphincter of a patient. The movement restriction device has a proximal and a distal end, wherein the distal end is adapted to stabilize and hold the distal end. The invention further comprises a control device for controlling the stimulation device to stimulate the cardia sphincter. The distal end can be further adapted to treat obesity, for example by stretching the wall of the stomach or filling out a volume of the stomach.

An apparatus for the treatment of acid reflux disease has an implantable movement restriction device adapted to be at least partly 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. The movement restriction device has a size of at least 125 mm.sup.3 and a circumference of at least 15 mm.
