Abstract: A microfracture instrument for applying microfracture therapy to a bone, the microfracture instrument comprising: an elongated shaft comprising a distal end and a proximal end; a needle comprising a body terminating in at least one sharp point, the needle being movably mounted to the distal end of the shaft for movement between an extended position for engaging the bone with the at least one sharp point of the needle and a retracted position for withdrawing the at least one sharp point of the needle from the bone; and a drive shaft movably mounted to the elongated shaft, the drive shaft being connected to the body of the needle so that movement of the drive shaft relative to the elongated shaft moves the needle between its extended position and its retracted position.

Abstract: An atherectomy catheter is provided for excising and imaging material in a body lumen. In one embodiment, the catheter comprises a catheter body, a cutting blade, and an imaging device. The cutting blade is mounted on the catheter body and configured to move between a first position and a second position relative to an aperture or cutting window. When the cutting blade is in the second position, the blade substantially closes the aperture on the catheter body. The imaging device which is mounted on or otherwise coupled to the cutting blade is configured to be in an imaging position when the cutting blade substantially closes the aperture or cutter window. This allows the imaging device to survey material within the cutting zone of the atherectomy catheter. By allowing the imaging device to view materials within this cutting zone, material may be imaged and then removed from the body lumen without having to reposition the catheter between each step.

Abstract: Devices and methods are provided for controlling and indicating the deployed length of an interventional element on an interventional catheter. The interventional element may be a stent or series of stents, a balloon, or any other interventional element for which length control is necessary or desirable. Devices for controlling the length of the interventional element include gear driven actuators, motors, and other mechanisms. Devices for indicating length of an interventional element to the user include sensors, detents, visual displays and other mechanisms providing visual, audible, and tangible indications of length to the user. The control and indication devices preferably work in tandem to enable highly precise adjustment of interventional element length.

Abstract: The method for performing an arthroscopic procedure on a joint using surgical navigation. A 3-D virtual model of the anatomy is created from a scan of the anatomy. The 3-D virtual model is then used to reproduce motion of the joint and plan the arthroscopic procedure. The 3-D virtual model is placed into registration with the real-world anatomy, so that a virtual image generated by the 3-D virtual model may be placed into registration with an arthroscopic image of the real-world anatomy. Preferably, arthroscopic registration markers, positioned prior to scanning, are used to place the 3-D virtual model in registration with the real-world anatomy. The arthroscopic registration markers may be placed either percutaneously or arthroscopically. At the conclusion of the procedure, the registration markers may be left in place, removed arthroscopically or allowed to biodegrade.

Abstract: The present invention provides a retractor for providing surgical access through a passage in tissue, together with methods for its use and deployment. The retractor comprises an anchoring frame having an upper surface, a lower surface, and an opening therethrough which defines an axial axis. A flexible tensioning member is attached to the frame, and is extendable from the frame out of the body through the passage when the frame is positioned through the passage and into a body cavity. This tensioning member is selectively tensionable to spread the tissue radially outwardly from the axial axis. Hence, it is the tension imposed on the flexible liner which effects retraction of the tissue, rather than relying on the structural integrity of an artificial lumen.

Abstract: The invention is directed to therapy devices for providing therapeutic light to a target region of tissue within a nasal cavity. The devices are adapted to include a light source communicating with a distal end of the first insertion member, wherein light from the light source illuminates a target region of tissue within a nasal cavity posterior to a limen nasi of the nasal cavity, and further wherein the insertion member is configured to prevent illumination of a region of tissue anterior to the limen nasi. The devices are further adapted to be positioned within the nasal cavity by a user without observing the location of the distal tip.
