A tunneling device for creating a pathway in subcutaneous tissue of a person's body. The tunneling device includes a member having two ends, where each of the ends defines an insertion surface that facilitates the insertion of the ends into the subcutaneous tissue of the person's body. The tunneling device includes an interchangeable handle connectable to each of the ends. The handle defines a grasping surface and an opening. The opening is configured to receive either of the ends. The grasping surface enables a user to securely hold the handle with one hand to forcibly move the member through the subcutaneous tissue of the person's body to create the pathway in the subcutaneous tissue, and pull a cable of an implant device through the created pathway.

The present invention relates to a device and method for making sclerosing foam, which is useful in the treatment of varicose veins and other venous conditions. The device comprises a continuous pathway that is at least partly formed of flexible or compressible material and that comprises a foam generating structure within the continuous pathway; the foam generating structure being formed of two or more elements, wherein each element defines at least one passageway of cross sectional area 1 m2 to 10 mm2 and said two or more elements being arranged in series; a port which allows introduction of material into or extraction of material out of the continuous pathway; and a liquid pathway that is at least partly formed of flexible or compressible material and is arranged to deliver liquid into the foam generating structure between a first and second element of the foam generating structure.

Unitary endoscopic vessel harvesting devices are disclosed. In some embodiments, such devices comprise an elongated body having a proximal end and a distal end; an inflatable, coated or conditioned tip disposed at the distal end of the elongated body; and a cutting unit having a first cutting portion and a second cutting portion, the first cutting portion and the second cutting portion being moveable in a longitudinal direction relative to the elongated body to capture a blood vessel between the first cutting portion and the second cutting portion, and being rotatable relative to one another circumferentially about the tip to cut the captured blood vessel.

An apparatus for harvesting a vessel from a body, includes: a cannula having a dissector for advancing along the vessel to create a tunnel, the dissector having a transparent portion; and an energy tool moveably coupled to the cannula, wherein the energy tool is configured to separate a pediculated vessel having at least a segment of the vessel and a pedicle around the segment of the vessel from surrounding tissue, and wherein at least a part of the energy tool is visible through the transparent portion of the dissector during use of the energy tool.

A variety of configurations of implant management devices are provided. The configurations provide different combinations of features for maintaining a location of an implant with respect to the device and managing filaments of the implant. One exemplary embodiment of a device includes a generally rectangular-shaped body having an implantable body retainer, an opening disposed a distance apart from the retainer and configured to receive a ligament graft therein, and a fold extending across the body and intersecting the opening. Folding one end of the body towards a bottom surface of the body along the fold can form a filament loop engaging region to hold in tension a filament loop extending from the implant. Additional filament(s) associated with the implant can be managed by various filament retention features. Methods for preparing a ligament graft for implantation by relying upon indicia formed on a surface of the device body are also provided.

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes providing an intravascular device having a distal portion with a side port, inserting the device into the vascular lumen, positioning the distal portion in the vascular wall, directing the distal portion within the vascular wall such that the distal portion moves at least partially laterally, and directing the side port towards the vascular lumen.

A precision blade apparatus includes a housing, a control mechanism, a blade motor and a power source, an adjustment dial, a retractable interchangeable blade operably coupled to the blade motor and configured to be operated by the control mechanism, an alignment mechanism operated by the control mechanism, and a secondary alignment mechanism attached to the alignment mechanism. The secondary alignment mechanism is configured to be aligned into a single point when the target object is appropriately centered within the alignment mechanism thereby allowing more nuanced control and illumination of a particular area of the target object. The adjustment dial is configured to calibrate and adjust a blade extension speed, a blade extension distance, a blade selection of the retractable interchangeable blade, a position of the alignment mechanism, operation of the secondary alignment mechanism, and power consumption.

A harvester for harvesting a vein, comprising a handle, a blade extending at an angle from the handle and having a spoon-shaped tip at a distal end of the blade, the spoon-shaped tip including a concave surface and a convex surface, and an image capturing assembly for capturing images of an operating field, the image capturing assembly including an image capturing device provided on the concave surface of the spoon-shaped tip.

This invention relates to device, systems, kits and methods that enable selective dissection of lung tissue to remove diseased tissue from healthy tissue without damaging blood vessels or airways. The invention and methods enable minimally invasive lung surgery procedures by providing a device and method to perform automated dissection that discriminates against traumatizing critical lung tissue.

One-piece tissue fasteners are provided for securing two or more tissue layers to each other. Delivery devices are described by which a tandem array of such fasteners can be delivered and deployed to secure tissue layers in a number of locations without requiring removal or reloading of the removal tool.
