Methods of using a soft tissue cutting device are disclosed. The methods include providing the soft tissue cutting device, positioning the soft tissue cutting device in a priming slot of a tray configured for receiving and holding the soft tissue cutting device, attaching a priming syringe to the soft tissue cutting device, priming a balloon disposed on a distal end of the soft tissue cutting device by equalizing a first pressure inside the balloon to a second pressure inside the priming syringe, removing the soft tissue cutting device from the priming slot, and positioning the distal end of the soft tissue cutting device on a safety slot included in the tray to determine whether the tissue cutting device has been properly primed.

Medical systems, devices and methods for creation of autologous tissue valves within a mammalian body are disclosed. One example of a device for creating a valve flap from a vessel wall includes an elongate tubular structure having a proximal portion and a distal portion and a longitudinal axis; a first lumen having a first exit port located on the distal portion of the elongate tubular structure; a second lumen having a second exit port located on the distal portion of the elongate tubular structure; a recessed distal surface on the distal portion of the elongate tubular structure, wherein the recessed distal surface is located distally to the first exit port; and an open trough on the recessed distal surface extending longitudinally from the first exit port.

A medical apparatus according to one embodiment of the present invention can be used for dissociating adhesion to an epidural space and alleviating stenosis to a spinal canal; and comprises: an insertion part including a first end configured to be inserted into a human body and a second end opposite to the first end, and having a first through hole extended from the first end to the second end and formed inside the insertion part, an expansion part configured to be expendable and formed on the outer surface of the insertion part at a predetermined distance apart from the first end of the insertion part, a pair of wires extending in the insertion part and fixed to the region of the first end of the insertion part, a main body, a dial installed to the main body, and a rotation control part coupled to the dial.

Devices and methods for locating sinus ostia and positioning a guide wire within the sinus ostia. The subject devices comprise a shaft having a distal end, a proximal end, a curved region located between the distal and proximal ends, and an interior channel, an extensible and retractable guide wire movably mounted within the interior channel and a probe tip joined to the guide wire. Certain devices further include expandable portions for engaging and treating body anatomy.

A tray for a soft tissue cutting device includes a housing slot for removably housing the soft tissue cutting device prior to use and a priming slot for receiving the soft tissue cutting device during a priming procedure. The priming slot allows connection of the soft tissue cutting device to a priming syringe for priming the soft tissue cutting device. The tray also includes a safety slot for testing whether the soft tissue cutting device is primed for use and a sterile cover connectable to the tray. The sterile cover substantially encloses the tray when it is connected thereto.

A mastopexy implant for maintaining the breast in an elevated and aesthetically pleasing position includes a lower pole support comprising end portions which may be affixed to the chest wall or to a previously installed upper suspension strut. The implant is loaded in an insertion device. The insertion device is inserted through a small incision and into a subcutaneous pocket created in an inferior half of the breast. The lower pole support may have various constructs and in one embodiment includes a unitary conformable mesh having a plurality of arm or band members which are attached across the breast parenchyma and to the chest wall.

A surgical instrument including a housing, an elongated body, an end effector, and a dissection element. The housing has a handle assembly and the elongated body extends from the housing. The end effector is supported at a distal end of the elongated body and is operatively associated with the handle assembly. The dissection element is disposed about the elongated body proximal to the distal end of the elongated body. The dissection element is configured to bluntly dissect tissue surrounding the elongated body.

Example devices and techniques are described herein for creating a multicuspid, multi-leaf interatrial shunt in the heart of a patient. An example device includes an elongate tool body and an inflatable balloon. The elongate tool body includes at least one lumen and a distal portion. The inflatable balloon is on the distal portion, and is configured to be inflated via the lumen. The inflatable balloon includes a distal outer surface configured for contacting an interatrial septum of a heart of a patient, and an ablation region of the distal outer surface of the inflatable balloon configured for ablating the interatrial septum when the inflatable balloon receives the ablation energy. The ablation region is disposed on the distal outer surface of the inflatable balloon in a manner that the ablation region creates a multicuspid ablation pattern when the inflatable balloon receives the ablation energy.

Device, systems, and method for cutting body tissue may include a handle, a blade, a shaft, and an expander. The handle may include a slider and a lever in communication with the slider. The blade may be coupled with the slider. The shaft may extend distally from the handle and the shaft may define a guideway along which the blade is configured to travel. The expander may be in communication with the lever and extend along the shaft. Actuation of the lever may adjust the expander to an expanded position and unlock the slider to allow actuation of the slider and longitudinal movement of the blade along the guideway. The expander may be or may include one or more balloons.

Tissue dissecting device, including an inflatable bladder configured to be inserted into a body via an introducer tube in a compact deflated state, and to be inflated to a substantially planar form in a manner which dissects tissue. Method for dissecting tissue, including inserting an inflatable bladder, in a deflated state, via an introducer tube, into a space in a body, and inflating the bladder to substantially planer form, thereby dissecting tissue. Method for dissecting tissue, including inserting an introducer tube via an incision into a body, inserting an inflatable bladder, in a defined state, via the introducer tube, into a space in the body, pulling the introducer tube back at least a length of the deflated bladder, inflating the bladder, via a filling tube, to substantially planar form, thereby dissecting tissue, disconnecting the filling tube from the bladder, retracting the filling tube and the introducer tube from the body.
