A surgical device controllable by a surgical robotic system is provided. The surgical device includes a housing capable of being coupled to the surgical robotic system; a drive system at least partially mounted in the housing; and a shaft rotatably coupled to the drive system at a first end of the shaft. The surgical device further includes a tissue-removal assembly coupled to the second end of the shaft. The tissue-removal assembly includes a first cutting member having a plurality of rotatable blades. The first cutting member is coupled to a second end of the shaft. The tissue-removal assembly further includes a second cutting member, one or more support elements slidably or fixedly coupled to the second cutting member, and one or more extendable elements slidably or fixedly coupled to the second cutting member.

Described are a multipurpose handles that can be incorporated into medical device delivery systems. Also described are medical devices, including medical snare devices, that can incorporate the handles or features thereof. An actuation button of the multipurpose handle can be moved longitudinally to move a device portion (e.g. snare loop) longitudinally, e.g. for deployment or retraction. The actuation button can also be rotated to rotate a device portion (e.g. snare loop). Sealing arrangements can be provided and can provide sealing functions in respect of a controlled medical device structure while the actuation button is moved longitudinally or rotated. Methods of using the handles and medical snare or other devices incorporating them are also described.

A papillotome for percutaneous endoscopic gastrostomy including a front opening located in a free end region of a catheter and at the outlet of a first lumen, a rear opening further from a free end than the front opening and connects the first lumen to the outside, and a cutting wire located in the first lumen in an axially displaceable manner and extends through the front opening and the rear opening and is located on the outside between the front opening and the rear opening. When the cutting wire is tensioned, the free end region is deformed in an arc shape and the cutting wire forms a transversely extending cutting edge between the front opening and the rear opening. The front opening is arranged at a distance of at least 3 mm from the free end. A projection is formed between the free end and the front opening. A cutting tip is formed at the free end of the catheter. The cutting tip is connected to the cutting wire and forms the foremost end of the papillotome.

The present invention relates to a device for incising a breast specimen, comprising: a fixing unit of which a portion is inserted into an incision window and which fixes a breast specimen to correspond to the entire size of the breast specimen; an incising unit for incising the fixed breast specimen; and an incising control unit adjusting the position and the incising angle of the incising unit.

A device suitable for use in a body lumen and comprises an elongated control member having a distal and a proximal end, and a radially expansible member disposed at or near the distal end and adapted for collection and/or shearing of matter (i.e. thrombus) from a wall of the body lumen (i.e. a vein or an artery). The radially expansible member has a proximal end and a distal end and is adjustable between a contracted orientation and an expanded orientation. The elongated control member comprising a proximal arm connected at or adjacent to the proximal end of the radially expansible member and a distal arm connected at or adjacent to the distal end of the radially expansible member such that movement of one arm relative to the other arm effects adjustment of the diameter or radial strength of the radially expansible member. The device comprises a control mechanism operatively connected to both arms and adapted to provide resistance to the movement of one arm relative to the other. The control mechanism may be a biasing means, a brake means, or both.

Disclosed herein are devices (e.g., needles (e.g., hollow needles), hollow staples, articles, apparatuses, and systems), kits, and methods for treating skin and skin conditions, for example, by promoting skin tightening, such as by reducing skin laxity and reducing tissue area or volume.

A medical device may include an insertion device having a proximal end, a distal end, and a lumen extending therethrough. The medical device may further include a snare device configured to transition between a contracted state within the lumen of the insertion device, and an expanded state extending distally of the insertion device. The snare device may include a loop including a pair of legs and a distal tip. The distal tip may include a plurality of stabilizers between the pair of legs.

A system for harvesting a tendon graft is disclosed, including a retractor, a guide and a harvesting tool. The retractor is collapsible and upon release, becomes self-supporting to hold open an anatomic space developed in a patient above the tendon. A guide assembles with the retractor to orient a guide shaft along the retractor and thereby the anatomic space. The harvesting tool includes a working end with a blade edge for cutting into the tendon. The harvesting tool defines a contoured surface for engaging and translating along the guide shaft while assembled to the retractor. The guide shaft and contoured surface limit the trajectory and translation extent of the harvesting tool along and into the tendon.
