  • Publication number: 20220354430
    Abstract: Stent apparatuses are provided. In some embodiments, the stent apparatus comprises: a tubular body; and at least two induction loops capable of generating an electrical current in the presence of one or more of magnetic, electrical, and radiofrequency energy. The stent apparatus may be placed in a non-target bodily tissue during surgery and used to sense the proximity of an electrosurgical instrument to prevent injury to the non-target tissue. Also provided herein are related systems and methods for protecting and/or mapping the non-target bodily tissue having the stent apparatus placed therein.

  • Patent number: 7534905
    Abstract: A new class of reagents and method of use of the reagents in the reaction of the reagents with electrophilic compounds. The invention in one embodiment is directed to a method for the formation of an alcohol of the formula (I). The method includes reacting a reagent of the formula (II) with an aldehyde of the formula R10CHO to form the alcohol. X3 is one of O and C(R4)(R5). Each of X1 and X2 is independently O or N—R. Each of Ca and Cb is independently an achiral center, an (S) chiral center or an (R) chiral center. Ra and Rb are (i) each independently C1-10 alkyl, C6-10 aryl or C3-9 heteroaryl, or (ii) taken together to form a C3—C4 alkylene chain which together with Ca and Cb forms a 5-membered or 6-membered aliphatic ring. Rc and Rd are each independently hydrogen, C1-10 alkyl, C6-10 aryl or C3-9 heteroaryl. R is C1-10 alkyl, C6-10 aryl or C3-9 heteroaryl.
