Surgical sheath

A surgical sheath adapted for use in the nasal cavity has an elongated hollow body made of a braided material having interstitial spaces with a dimension of 0.25 mm to 1.50 mm. The interstitial spaces filled with a filling material, such as silicone. The sheath has a low profile configuration during placement into the naris, and may be stretched into an expanded configuration. In methods of placing the sheath in the naris, the sheath is folded and then pulled into the naris using a surgical tool.

Surgical tissue protection sheath

In a surgical method, an access sheath is provided by a tube of a braided material. A first end of the sheath may be folded. The first end, folded or unfolded, is grasped with a distal end of a tool, which is then inserted into the nose of a patient. Advancing the tool pulls the distal end of the sheath into the nose of the patient. The sheath is then released from the tool and the tool is withdrawn. A portion of the sheath may be optionally cut off to shorten the sheath to a desired length. Typically the sheath has a total length of 70 to 180 mm and an outside diameter of 12 to 50 mm. The sheath may have a constant outside diameter along its length. The sheath may comprise silicone on the braided material.

Surgical access sheath and methods of use

In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.

Stent and stent delivery device

An implant delivery system is described. The implant delivery system utilizes an implant, implant wire, delivery sheath, and a torque device. The torque device may include a cutting element to slit the delivery sheath and a clamp device to fix the position of the implant delivery wire.

System and method for implant delivery

An embolic protection device includes an expandable and contractible filter that can be supported by one or more struts. The struts can be connected to the filter or interwoven into the filter, so as to assist in the expansion and contraction of the filter. In one embodiment, the proximal ends of the struts connect to a joint that is fixed in position relative to a delivery wire, while the distal end of the filter connect to a joint that slides relative to the delivery wire.

Embolic protection device

An implant delivery system is described, having a distal tip and outer sheath that remain in a fixed position during implant delivery. A pusher mechanism within the sheath pushes an implant out of a gap between a distal end of the sheath and the distal tip.

Pushable implant delivery system

Apparatus for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. The stabilizing members can be adapted to become angled relative to a longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.

Apparatus for manipulating and securing tissue

A vascular prosthesis is described, having blunted wire ends. The blunted wire ends can take on a variety of configurations including end caps, bent ends, curved ends, or eyelets. The novel ends provide a smooth surface to contact the blood vessel walls thereby reducing the risk of trauma during placement of the prosthesis.

Vessel prosthesis

A surgical sheath for use in endoscopic trans-nasal or intra-ocular surgery is made of a braid material. The sheath may be manufactured by placing a length of braided tube material over a mandrel. The braid material is conformed to the shape of the mandrel and is then heat set. An atraumatic end may be made by folding or rolling one or both ends of the sheath. A coating may also optionally be applied to the braid material. The sheath reduces collateral trauma to the tissues in the surgical pathway.
