METHODS AND DEVICES FOR VEIN HARVESTING
A vein harvesting device is disclosed. The vein harvesting device includes a handle assembly, at least one elongated portion, first and second end effectors, and a tip. Each end effector is disposed adjacent a distal portion of the at least one elongated portion. Each end effector includes a first jaw member and a second jaw member, and at least one jaw member is movable toward the other jaw member. The tip is disposed in mechanical cooperation with the elongated portion. A distal end of the tip extends distally beyond a distal-most end of the first end effector. The first end effector is movable independently of the tip, and the second end effector is movable independently of the tip.
Vein dissecting device and method
A vein harvesting device for harvesting a vein in a living body includes an elongated hollow member possessing a distal end portion and a proximal end portion, and a dissecting member at the distal end portion of the elongated hollow member and configured to dissect tissue in the body surrounding the vein during harvesting of the vein, wherein the dissecting member possessing a proximal end portion communicating with the elongated hollow member. The dissecting member possesses two side portions, with each of the side portions possessing a first end at an end of the side portion farther from the hollow member and a second end at an end of the side portion closer to the hollow member. A projection projects from the first end at each of the side portions of the dissecting member to contact the tissue in the body surrounding the vein during the harvesting of the vein.
Minimally invasive no touch (MINT) procedure for harvesting the great saphenous vein (GSV) and venous hydrodissector and retractor for use during the MINT procedure
A hydrodissector for hydrodissecting a vein, 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 configured to be coupled to a fluid supply for supplying fluid at a substantially constant pressure, and provided at the distal end of the shaft, and an image capturing assembly configured to provide direct visualization of the vein during hydrodissection. A minimally invasive method for dissecting a greater saphenous vein (GSV) from surrounding tissues using the hydrodissector is also described.
Methods and devices for vein harvesting
A vein harvesting device is disclosed. The vein harvesting device includes a handle assembly, at least one elongated portion, first and second end effectors, and a tip. Each end effector is disposed adjacent a distal portion of the at least one elongated portion. Each end effector includes a first jaw member and a second jaw member, and at least one jaw member is movable toward the other jaw member. The tip is disposed in mechanical cooperation with the elongated portion. A distal end of the tip extends distally beyond a distal-most end of the first end effector. The first end effector is movable independently of the tip, and the second end effector is movable independently of the tip.
WIRE AND DEVICE FOR VASCULAR TREATMENT
A wire for use with a vascular treatment device may have a proximal end, a distal end, and a main shaft extending therebetween. The distal end may have a distal free end and a first segment. The first segment may extend from the main shaft and may be biased to a first included angle that is defined between the main shaft and the first segment and less than 180 degrees.
Devices and methods for modifying veins and other bodily vessels
The present disclosure provides, in certain aspects, unique products and methods for abrading or otherwise disrupting an interior surface of a bodily a vessel. In some forms, these products and methods further incorporate the use of one or more occluding members to be deployed in the bodily vessel in and/or around a disrupted vessel region. Abrasive endoluminal devices, in certain embodiments, exhibit a low-profile first condition for delivery into and/or through the vasculature. The device can then be transitioned to a second, expanded condition inside the vasculature for carrying out a desired abrasion. With these types of devices, the manner and design by which the device transitions from a first condition to a second condition can vary. Embodiments of such are disclosed herein.
Method and apparatus for occluding a blood vessel
Apparatus for percutaneously occluding a hollow structure, said apparatus comprising: an occluder, said occluder comprising a first component and a second component, wherein said first component is configured so that it may assume (i) a diametrically-reduced configuration for disposition within the lumen of a hollow tube, and (ii) a diametrically-expanded configuration for disposition adjacent to the hollow structure, whereby to occlude the hollow structure, and further wherein said second component percutaneously connects said first component to a site remote from said first component.
Surgical Insufflation and Irrigation Conduits and Methods for Use
The presently disclosed embodiments relate to insufflation and irrigation conduits for vessel harvesting systems and methods of their use. In particular, the present disclosure relates to a system having a combined cabling for providing gases, liquids, and/or electrical power to an attached medical device and method of use.
Endoscopic vessel harvesting devices with conditioning of insufflation gas
A vessel harvesting apparatus for removing a blood vessel from a patient includes collection and conditioning (i.e., treatment) of expelled insufflation gas prior to releasing the gas into the air of the operating room. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. An insufflation channel is configured to convey an insufflation gas subcutaneously into a dissected space within the patient. A removal channel is configured to evacuate fluidic contents from the dissected space, wherein the fluidic contents include insufflation gas and biological impurities. A processor/separator is coupled to the removal channel to process the fluidic contents to retain at least some of the biological impurities and to exhaust the insufflation gas.
Methods and devices for vein harvesting
A vein harvesting device is disclosed. The vein harvesting device includes a handle assembly, an elongated portion extending distally from the handle assembly and defining a longitudinal axis, an end effector, and a retractor. The end effector is disposed adjacent a distal portion of the elongated portion, and includes a first jaw member and a second jaw member. At least one jaw member is movable toward the other jaw member. The retractor is disposed in mechanical cooperation with the elongated portion, and includes a shaft and a pair of legs. The retractor is movable from a non-deployed position where the shaft is aligned with the longitudinal axis, to a deployed position where the shaft is disposed at an angle with respect to the longitudinal axis.
