摘要:
The subject invention provides systems and methodologies for fabrication of memory and/or selection (e.g., diodes) elements in a recession in a semiconductor layer. In particular, a trench of varying width is created in the semiconductor layer by employing various etching techniques. A metal film can be deposited in the trench according to a desired deposition thickness in order to seam close a narrow portion of the trench while form a dimple in a wide portion of the trench. The trench, after metal film deposition, exhibits a depression in wider trench portions relative to narrow trench portions. The depression can be utilized by placing one or more memory or selection layers in the depression, and a via can be formed over a portion of the trench to form an interconnect.

A device for percutaneously excising tissue. In an embodiments the device comprises an outer tubular. In addition, the device comprises an inner tubular slidingly received within the outer tubular, wherein the inner tubular has a distal end including an upper member and a lower member. Further, the device includes an open position with the distal end fully extended from the outer tubular, and a closed position with the distal end disposed within the outer tubular, wherein the upper member is biased away from the lower member and is disposed at an open angle θO relative to the lower member when the device is in the opened position.

A bone anchor insertion device comprises a handle, a nosepiece connected to a distal end of the handle, a bone anchor connected to the nosepiece, and an actuator disposed on the handle for deploying the bone anchor, which suture is also fixed to a portion of soft tissue to be attached to a portion of bone. A suture ratchet or tensioning mechanism is disposed in the handle for tensioning suture which is associated with the bone anchor. This mechanism permits precise tensioning, while also permitting one-handed operation, thereby allowing the practitioner to use his or her other hand for other activities, such as camera operation or the like.

A variable optical attenuator (200) comprises a dual fiber collimator (202) and a reflection component (206) separated by a linear moveable ND filter (204). The collimator (202) includes a ferrule (304) with dual fibers (310, 320) therein, and a GRIN lens (302) spaced from the ferrule (304) with a distance in compliance with the distance between the reflection component (206) and the GRIN lens (302).
摘要:
A bone anchor and methods for using same to secure connective tissue, such as tendons, to bone are disclosed which permit a suture attachment that lies entirely beneath the cortical bone surface. The bone anchor of the invention incorporates a deformable body that creates an increased anchor body diameter after it is inserted into the cancellous bone and deployed beneath the cortical surface of the bone. The increased body diameter, by virtue of its intrinsic geometry, creates both axial and rotational fixation of the bone anchor or suture fixation point.
