The present application provides a device (100) for transferring a fluid from a surgical site, comprising an elongate body portion (102) defining a proximal end region (106) connectable to a source of negative pressure; an elongate neck portion (104) defining a distal end region (108) of the device locatable at a surgical site; a through bore (118) extending from the distal end region to the proximal end region; and a control member (116) for selectively controlling a negative pressure at the distal end region, wherein the control member comprises a valve portion (124) configured to at least partially restrict a fluid flowing along the through bore when moved from an open position towards a closed position. A system including the device for transferring a fluid from a surgical site is also provided.

A device, kit, and method for aspirating graft tissue and delivering the graft tissue to a target delivery site. An injector comprises a cylinder and a plunger that is both linearly and rotatably advanceable and retractable within the cylinder. A kit comprises an injector, a cartridge, and a cartridge coupling element that connects the cartridge to the injector. The kit may also include a container that is configured to retain a cartridge and to facilitate connection between the injector and the cartridge. The container includes at least one fluid barrier that prevents spillage of storage solution from the container when the injector is at least partially inserted into the well of the container.

A surgical cutting instrument comprises an outer tubular member and an inner tubular member. The outer tubular member includes a proximal section, an intermediate section, a distal section, and a side wall. The side wall defines a central lumen extending from the proximal section to the distal section. The side wall also includes means for conducting fluid within a sidewall of the outer tubular member from the proximal section to the distal section and includes a distal opening positioned to direct fluid at the bur and a treatment site. The inner tubular member is rotatably received within the central lumen. A distal end of the inner tubular member forms a bur extending distally beyond, and exposed relative to, the distal section of the outer tubular member.

A coiled shaft for tissue disruption is described herein where a flexible aspiration cannula has a first portion and a second portion formed of the coiled shaft. The cannula is configured in a particular embodiment to rotate over the length of the cannula to disrupt the matrix of bone marrow without the cannula buckling or collapsing. The cannula also includes a disruption tip coupled to the coiled shaft. The disruption tip has a radiused portion along a distal tip face of the disruption tip.

A conveying device for body fluid includes a catheter tube having a distal end to be inserted into the body and a proximal end. In order to provide a conveying device which can no longer become clogged with coagulating substances, a hollow body which is arranged in a longitudinally moveable and/or rotatable manner in the catheter tube, extends from the distal end at least up to the proximal end, and forms a transport channel over its length extending in the extension direction of the catheter tube.

A uterine fibroid tissue removal device includes an inner tube disposed within an outer tube and configured to be translated and rotated relative to the outer tube, and a separately formed unitary distal tip member attached to a distal end of the inner tube, such that the distal tip member translates and rotates relative to the outer tube along with the inner tube, wherein a distal facing open cutting end of the distal tip member in fluid communication with an axial lumen of the distal tip member translates across a tissue resection window in a sidewall of the outer tube so as to sever tissue extending therethrough, the distal tip member axial lumen being in fluid communication with an axial lumen of the inner tube, wherein an outer diameter of the distal tip member is greater than an outer diameter of the inner tube.

A coiled shaft for tissue disruption is described herein where a flexible aspiration cannula has a first portion and a second portion formed of the coiled shaft. The cannula is configured in a particular embodiment to rotate over the length of the cannula to disrupt the matrix of bone marrow without the cannula buckling or collapsing. The cannula also includes a disruption tip coupled to the coiled shaft. The disruption tip has a radiused portion along a distal tip face of the disruption tip.

A device for visualizing and providing suction for a surgical procedure in an ear may include a handle, a main shaft extending from the handle, an imaging sensor at a distal end of the main shaft, a light source at the distal end of the main shaft, and a suction shaft extending from the handle. The device may also include a spring coupled with the suction shaft and/or the handle, such that when the suction shaft is advanced in a distal direction and then released, the suction shaft retracts automatically. The suction shaft may have a distal curved portion, and the device may have a thumb depress portion that allows a user to spin the suction shaft to suction in different directions. Some embodiments may include a suction shaft with a sharp distal tip that is configured for placing an ear tube in the tympanic membrane.

A device for minimizing obstruction in a medical device that carries fluids includes a housing defining a channel configured to receive and secure a section of the medical device such that the section of the medical device extends coaxially with a central longitudinal axis of the channel. The device also includes components supported in the housing, including a motor, wherein the components are configured to be operated to impart motion to the housing and the attached medical device. The motion is configured to produce oscillatory motion of a frequency sufficient to concentrate shear stresses in a fluid boundary layer adjacent an inner wall of the medical device. The housing and the components supported in the housing are configured and arranged so that a device center of mass lies along or near the longitudinal axis of the channel.

A device for removing fat from a body can include a pair of nested hollow members that each has at least one opening and an adjustment means for adjusting the orientation of the nested hollow members from a first configuration to a second configuration to change an amount of overlap between openings in the nested hollow members. The nested members can be deformable to change the shape of the openings.
