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 a first intravascular device having a distal portion with a concave side, inserting the first device into the vascular lumen, positioning the distal portion in the vascular wall, and orienting the concave side of the distal portion toward the vascular lumen.

A method for collapsing a target vein in a patient. The method comprises providing an intravascular irritation element having a plurality of mechanical irritating objects, inserting the intravascular irritation element into a venous lumen of a target vein, and irritating the target vein by moving the plurality of mechanical irritating objects in contact with the inner surface thereof, thereby triggering a collapse of the target vein.

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.

This disclosure relates to a surgical device configured to both strip and cut a tendon. The harvested tendon can be used in various orthopedic procedures, such as ACL, PCL, and UCL reconstructions.

Unitary endoscopic vessel harvesting devices are disclosed. In some embodiments, such devices may comprise an elongated body having a proximal end and a distal end. A conical tip may be disposed at the distal end of the elongated body. In addition, the surgical instrument may include one or more surgical instruments moveable in a longitudinal direction along an axis substantially parallel to a central longitudinal axis of the cannula from a retracted position proximally of a distal end of the tip to an advanced position toward the distal end of the tip to seal and cut a blood vessel.

A fastener or clamp for securing a tissue layer to another tissue or non-tissue layer has a proximal implant and a separate distal implant, connectible to each other, each implant having radially deployable legs that can engage the layers between the deployed legs, the legs being configured so that when the implants are connected, the legs of the proximal and distal implants are interdigitated in the absence of tissue.

A tendo calcaneus suturing instrument, comprising: a first support and a second support that are of a U-shaped structure, a distance adjustment device, a first guide sleeve, a second guide sleeve, a first positioning tube, a second positioning tube and a tendo sheath cutter. An outer arm and an inner arm of the first support, and an outer arm and an inner arm of the second support are respectively provided with a first positioning hole, a first guide hole, a second positioning hole and a second guide hole; and the first guide sleeve/the second guide sleeve is fixed by means of the first positioning hole/the second positioning hole and is matched with the first guide hole/the second guide hole. The first positioning tube/the second positioning tube provided with a through hole is arranged in the first guide sleeve/the second positioning sleeve or the tendo sheath cutter is arranged in the first guide sleeve and/or the second guide sleeve in a matching manner. The tendo calcaneus suturing instrument can simplify the surgical procedure, improve the surgical effect and relieve pains of a patient.

A device (1, 30, 40, 50, 60) for denuding a vein comprises a vein denuding head (3) operatively attached to an elongated catheter member (2) and configured for transluminal delivery and deployment in the vein. The vein denuding head comprises a helical coil (4) that is self-adjustable from an uncoiled delivery configuration suitable for transluminal delivery within the catheter member and a coiled deployed configuration having a diameter greater than the vein to be denuded that circumferentially engages an internal lumen of the vein when deployed. The helical coil has an abrasive surface configured to circumferentially denude the internal lumen of the vein when the coil is moved axially along the body lumen in the coiled configuration. The helical coil may be a single helical coil element.

A hydrodissector for hydrodissecting a vascular target, the hydrodissector comprising: a handle; a shaft extending from the handle at an angle and including a tip at a distal end thereof; at least one port provided at the tip and configured to be coupled to a fluid supply and to eject fluid from the at least one port into the space between the vascular target and surrounding tissues to dissect the vascular target from the surrounding tissues, the at least one port being sized to provide sufficient pressure and velocity to dissect the vascular target from the surrounding tissues, wherein the length of the shaft is configured for insertion into an incision to atraumatically hydrodissect the vascular target from the surrounding tissues, and wherein the shaft is configured to releasably couple with one or more hook-shaped attachments configured to lift the vascular target after the vascular target is dissected from the surrounding tissues.
