A trialing and preparation system for preparing a disc space between two adjacent vertebrae is provided. The system includes a guide shaft, a trialing cage or spacer, a scraper and a driving shaft. The guide shaft supports the trialing spacer within the disc space and may include an angular adjustment for such access. The scraper sleeves over the guide shaft into an abutting relationship with the adjacent vertebrae. The driving shaft is coupled to the scraper by a pivoting and reciprocation mechanism that allows angular adjustment of the scraper. Also, reciprocation of the driving shaft reciprocates the scraper through a limited sweep of motion to remove osteophytes from the vertebrae.

Vertebral scraper

An intra-luminal device for the extraction of occlusive or partially occlusive material is disclosed. Said device comprises a novel catheter extension which minimizes cavitation of extracted fluids and also allows the better navigation of tortuous lumens or vasculature.

Catheter with associated extension lumen

An intra-luminal device for the extraction of occlusive or partially occlusive material is disclosed. The device includes a novel catheter extension which minimizes cavitation of extracted fluids and also allows the better navigation of tortuous lumens or vasculature.

A pumping system for use in medical applications where liquids must be infused and aspirated from a mammalian patient, and whose economics are such that it is cost effective to simply dispose of it after a single use. The system features positive displacement pump(s) such as reciprocating pump(s) containing a damping mechanism to dampen out the peaks and valleys in the fluid pressure that is pumped, which is important for preventing cavitation. The system furthermore features a shut-off valve on the extraction side so that certain injected fluids such as contrast medium, are not immediately pumped out of the patient. In a preferred embodiment, the system also features means for independently controlling the fluid pressure/volume on the infusion and extraction sides, self-priming capability, a continuous fluid path, and visual air bubble detection, with viewports located at important points in the fluid path, such as at pumps and valves.

Interventional procedure drive and control system

An attachment tool to facilitate the attachment of one or more catheters or similar elongated instruments to a guide-wire or other elongated guide member, without requiring access to either end of said wire or member. The tool provides repeatable and reliable alignment of components to be attached, while being operated with a single hand. The catheter systems can be used for revascularization or treatment of arteries and lumens within the body, and the associated delivery of therapies therein and can include side attachable and over-the-wire components and/or low profile combination catheters to allow for flush and extraction of debris in small or tortuous anatomic pathways.

Tool for facilitating the connecting of a catheter or other tubular member onto a guide-wire without access to the ends of the guide wire

Instrument including connector for facilitating connection onto a guide-wire without access to the ends of the guide-wire and method of use

A tubular instrument including a hollow wall portion and a connector arranged to be used with a guide-wire. The guide-wire has a distal end portion and a proximal end portion, the distal end portion of the guide-wire is arranged to be extended to some interior position within the body of a living being, with the proximal end portion of the guide-wire being located outside the being's body. The connector is located at the distal end of the instrument and is arranged to be readily manipulated by a twisting action to connect the instrument onto the guide-wire for sliding movement therealong.

A tubular instrument, e.g., a catheter including a hollow wall portion forming the distal end of the instrument and terminating at a distal opening, having a connector arranged to be used with a guide-wire. The guide wire has a distal end portion and a proximal end portion, the distal end portion of the guide-wire being arranged to be extended to some interior position within the body of a living being, with the proximal end portion of the guide-wire being located outside the being's body. The connector is located at the distal end of the instrument and is arranged to be readily manipulated by a twisting action to connect the instrument onto the guide-wire for sliding movement therealong. In particular, the connector establishes a path into which a portion of the guide-wire can be inserted from a lateral direction by merely twisting the instrument, without requiring access to either end of the guide-wire. In one embodiment the path is a spiral channel formed in the hollow wall portion of the instrument. In another embodiment the connector is a spiral member located on the outside of the distal end of the instrument, spaced slightly from the outer surface of the instrument to form the path or channel into which the guide-wire is inserted.
