A system for removing a kidney stone from a ureter may include: an elongate, flexible, outer shaft having a distal end configured to be advanced into the ureter and a proximal end; an elongate, flexible, inner shaft extending through at least part of the outer shaft; an expandable stone retention member extending through at least part of the inner shaft and moveable along the longitudinal axis relative to the inner shaft; an elongate, flexible camera positioned coaxially within the retention member shaft, such that a distal end of the camera is located at or near a distal end of the inner shaft; and a handle coupled with the proximal end of the outer shaft, a proximal end of the inner shaft, and a proximal end of the retention member shaft.

A platform device for material excision or removal from vascular structures for either handheld or stereotactic table use may comprise a work element or elements configured to selectively open and close at least one articulable beak or scoopula configured to penetrate and remove intra-vascular materials or obstructions, or follow a central lumen of another device or over a wire in a longitudinal direction. Flush and vacuum tissue transport mechanisms may be incorporated. A single tube or an inner sheath and an outer sheath which may be co-axially disposed relative to a work element may be configured to actuate a beak or beaks or scoopulas and provisions for simultaneous beak or scoopula closing under rotation may be incorporated.

A minimally invasive ultrasonic osteotome head and a minimally invasive ultrasonic powered system for bone; the minimally invasive ultrasonic osteotome head comprises an osteotome rod (11, 21, 31, 41, 51, 61) and a head end (12, 22, 32, 42, 52, 62), the head end (12, 22, 32, 42, 52, 62) being located at a front end of the osteotome rod(11, 21, 31, 41, 51, 61), and the head end (12, 22, 32, 42, 52, 62) being bent laterally at a certain angle, wherein knurled teeth or skewed teeth are provided on the bent portion. By means of bending the head end (12, 22, 32, 42, 52, 62), bone tissue around the transforaminal endoscope may be removed. Therefore, a surgeon may, as much as possible, have more operation space under the limited endoscope channel, thereby increasing bone removal efficiency.

A microsurgical device and methods of its use can be used for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques. A dual-blade device can be used for cutting the trabecular meshwork (“TM”) in the eye. The device tip provides entry into the Schlemm's canal via its size (i.e., for example, 0.2-0.3 mm width) and configuration where a ramp elevates the TM away from the outer wall of the Schlemm's canal and guides the TM to first and second lateral elements for creating first and second incisions through the TM. The dimensions and configuration of the blade is such that an entire strip of TM is removed without leaving TM leaflets behind and without causing collateral damage to adjacent tissues.

A tissue resecting device includes a housing having an outer shaft, the outer shaft including a tool portion disposed at a distal end thereof having a window defined therein with a proximal cutting edge. An inner shaft is disposed within the outer shaft and includes proximal and distal ends, the inner shaft configured to rotate upon actuation thereof. A cork-screw member extends distally from the distal end of the inner shaft and into the window. The cork-screw member is configured to rotate concomitantly with the inner shaft and includes a barb at a distal end thereof configured to pierce and retain tissue thereon. Upon rotation of the inner shaft, the barb pierces and retains tissue and withdraws tissue proximally along the cork-screw member and into the outer shaft and wherein excess tissue is excised by the proximal cutting edge of the window as the tissue is withdrawn through the outer shaft.

A vitrectomy probe outfitted with a vitrectomy needle having a region of enhanced frictional character which may be referred to as an “augmented” surface region. This region may be utilized to interface with tissues such as the hyaloid membrane for forcibly shearing it from, for example, the underlying retina in a manner that avoids a degree of pulling forces on the retina in achieving the hyaloid detachment. By utilizing the vitrectomy probe to achieve the detachment, a subsequent intervention to introduce the probe for uptake of the sheared or detached hyaloid membrane material may also be avoided.

A biopsy needle for collecting a tissue specimen includes an outer cannula and an inner tube received within the outer cannula and configured to receive a stylet. The outer cannula is fixedly coupled to a needle holder that is coupled to and moves with a movable base that is axially movable within the handle housing. An inner driven structure (curvilinear part) is configured to selectively engage the movable base and travel therewith in a first stage of operation and in a second stage of operation in which the inner driven structure is disengaged from the movable base, the inner driven structure is driven along the movable base which is held in a stationary position. The coupling between the inner driven structure and the inner tube is such that the axial driving of the inner driven structure imparts rotation to the inner tube relative to the outer cannula.

Systems, instruments, and methods are described in which an apparatus comprises a housing including a scalpet device. The scalpet device includes a scalpet array that includes scalpets arranged in a pattern. The scalpets are deployable from the housing to generate incised skin pixels at a target site. The housing is positioned and the scalpet array is deployed into tissue at the target site. Incised skin pixels are generated when the target site is a donor site, and skin defects are generated when the target site is a recipient site. The incised skin pixels are harvested.

The present invention relates to a method for selecting a patient for an implant removal procedure, wherein the patient as a subcutaneously implanted rod and is in need of removal of said rod.

A medical device may include a handpiece having a housing and a drive system arranged within the housing. The drive system may be adapted to operate a tool in direct contact with human matter of a patient at a treatment site. The device may also include a suction system integrated into the drive system and configured to remove human matter from the treatment site. The device may also include a motor removably attached to the housing and configured for delivering rotational power to the drive system while avoiding contact with the human matter.
