Apparatus and method for treatment of benign prostatic hyperplasia

An apparatus and a method for treatment of benign prostatic hyperplasia are disclosed. The apparatus includes an applicator piece carrying a set of electrodes shaped and positioned to create a substantial electric field in the volume of hyperplasia and a pulse generator adapted for delivery of electrical pulses above the upper electroporation limit for the neoplastic cells. The amplitude, duration and number of the electrical pulses are generally selected to cause necrosis of a significant fraction of the volume of benign prostatic hyperplasia. The apparatus may include a high frequency system for heating the prostatic tissue and a cooling system for cooling the urethra. The combined action of heating and cooling may increase the temperature of the prostate cells to 45° C. to 55° C., while keeping the urinary tract at a temperature 15° C. to 20° C. This temperature distribution can increase the selectivity of the treatment by increasing susceptibility of the neoplastic cells to the electroporation treatment and decreasing it for the normal urethral tissues.

Human antibodies that bind human TNFα

Human antibodies, preferably recombinant human antibodies, that specifically bind to human tumor necrosis factor a (hTNFα) are disclosed. These antibodies have high affinity for hTNFα (e.g., Kd=10−8 M or less), a slow off rate for hTNFα dissociation (e.g., Koff=10−3 sec−1 or less) and neutralize hTNFα activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antibody portions, of the invention are useful for detecting hTNFα and for inhibiting hTNFα activity, e.g., in a human subject suffering from a disorder in which hTNFα activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant human antibodies of the invention, and methods of synthesizing the recombinant human antibodies, are also encompassed by the invention.

Implants and methods for treating bone

An orthopedic implant comprising a deformable, expandable implant body configured for treating abnormalities in bones, such as compression fractures of vertebra, necrosis of femurs and the like. An exemplary implant body comprises a small cross-section threaded element that is introduced into a bone region and thereafter is expanded into a larger cross-section, monolithic assembly to provide a bone support. In one embodiment, the implant body is at least partly fabricated of a magnesium alloy that is biodegradable to allow for later tissue ingrowth.

Ultrasonic cutting device

An ultrasonic surgical cutting method and apparatus is provided wherein the method and apparatus allows for the cutting of bone from within a hollow pathway such that a cutter associated with the ultrasonic method and apparatus remains sufficiently cool to prevent necrosis of the bone being cut. Furthermore the ultrasonic device and method can be employed in the cutting of soft tissue, wherein a cooled cutter is used to prevent the sticking of soft tissue to the cutting blade of the device during use.

Prevention of regression in thermal ciliary muscle tendinoplasty

Methods and apparatus are provided that prevent or inhibit functional regression caused by the stromal remodeling resulting from epithelial or fibroblastic apoptosis or necrosis in patients who will undergo or have undergone a thermal ciliary muscle tendinoplasty or scleral collagen shrinkage procedures. Methods and compositions are provided that prevent apoptosis in epithelial cells by stromal cooling during thermal tendinoplasty procedures; that create or restore stabilizing molecular cross-links between scleral stromal lamellar fibers; and that interrupt at least one step in the stromal remodeling response including inhibition of apoptosis, fibroblastic proliferation and migration, and inhibition of collagenesis.
