    摘要: A low-dose-rate (LDR) brachytherapy device having a spatiotemporal radiation profile includes an elongated body having a radioactive material in a spatial pattern to provide a spatial radiation profile with a radiation intensity that varies along a length of the elongated body. The radioactive material includes at least first and second radioisotopes having at least first and second respective decay profiles that together provide a temporal radiation profile that is different from the first and second decay profiles. The spatial radiation profile and the temporal radiation profile form a net spatiotemporal radiation profile configured to provide a radiotherapy plan for a patient.

    摘要: A suture anchor for approximating tissue to bone comprises an anchor member for securing the suture anchor to the bone and a plurality of sutures mounted to the anchor member so that the sutures extend outwardly from the anchor member. Each suture has a sharp pointed end for penetrating the tissue and a plurality of barbs which permit movement of the sutures through the tissue in one direction of movement of the pointed end and prevent movement of the sutures relative to the tissue in the opposite direction. The ends of the sutures are inserted and pushed through the tissue along a curvilinear path in a direction away from the bone. The sutures are drawn from exit points longitudinally spaced from the points of insertion and reinserted and advanced along a curvilinear path in the direction away from the bone. The sutures are drawn through the tissue while approximating the tissue adjacent the bone along the suture and leaving a length of the sutures in the tissue. The exit and entry points of two of the sutures are adjacent and the paths of the sutures substantially mirror one another.

    摘要: A biocompatible monomer composition contains (A) at least one monomer of the formula:CHR.dbd.CXYwherein X and Y are each strong electron withdrawing groups, and R is H or, provided that X and Y are both cyano groups, a C.sub.1 -C.sub.4 alkyl group; and (B) an effective amount of at least one biocompatible agent effective to reduce active formaldehyde concentration levels, preferably a formaldehyde scavenger compound. The monomer is preferably an alpha-cyanoacrylate. The formaldehyde scavenger compound may be in microencapsulated or non-microencapsulated form. The composition can be applied to a variety of materials and is particularly suitable as in vivo tissue adhesive. A method of joining together in vivo two surfaces, e.g., body tissues, includes (a) applying to at least one of the surfaces a composition containing 1) at least one monomer, preferably an alpha-cyanoacrylate, which forms a polymer whose in vivo biodegradation produces formaldehyde; and 2) an effective amount of at least one biocompatible agent effective to reduce active formaldehyde concentration levels, preferably a formaldehyde scavenger; and (b) maintaining the surfaces in contact until the composition polymerizes.

The composition can be applied to a variety of materials and is particularly suitable as in vivo tissue adhesive. A method of joining together in vivo two surfaces, e.g., body tissues, includes (a) holding damaged tissue edges together to form abutted tissue surfaces; (b) applying to the abutted tissue surfaces an excessive amount of a composition containing 1) at least one monomer, which forms a medically acceptable biodegradable polymer, 2) at least one plasticizing agent; and 3) at least one acidic stabilizing agent; and (c) maintaining the surfaces in contact until the composition polymerizes to form a thick film of polymerized composition bridging the abutted tissue surfaces.
