Patent number: 6719747Abstract: Catheter devices and methods are provided for enhancing fluid flow through a vascular site occupied by a calcified lesion. The catheter devices of the subject invention at least include, at their distal end, a proton generating means, and in many embodiments also include a flushing means. In using the subject devices, the distal end of the catheter is placed proximal to the vascular occlusion and protons are generated, e.g., via proton generation from water, in a manner sufficient to reduce the pH of the vascular site in the region proximal to the occlusion. The subphysiologic pH is maintained for a period of time sufficient for fluid flow through the vascular site to be enhanced. Also provided are kits comprising the subject catheter devices for use in the subject methods.Type: GrantFiled: February 4, 2003Date of Patent: April 13, 2004Assignee: Corazon Technologies, Inc.Inventors: Brent R.

Patent number: 6075121Abstract: Peptoids are provided which are polymers comprised of monomer units wherein the monomer units include at least some substitute amino acids and may include conventional amino acids. The peptoids can be synthesized in large numbers so as to provide libraries of peptoids which can be screened in order to isolate peptoids of desired biological activity. Although the peptoids may include amino acids, they preferably include only substituted amino acids and are designed in a manner so as to have a particular biological activity. Certain peptoids are designed to mimic as closely as possible the activity of known proteins. Other peptoids are designed so as to have greater or lesser activity than known proteins and may be designed so as to block known receptor sites and/or elicit a desired immunogenic response and thereby act as vaccines. In that the peptoids are comprised of substitute amino acids they can be designed to have structures which natural proteins cannot conform to.Type: GrantFiled: May 10, 1995Date of Patent: June 13, 2000Assignee: Chiron CorporationInventors: Reyna J.

Patent number: 5789577Abstract: A method to obtain selected individual polynucleotides or mixtures thereof each of which encodes a peptide and at least one polynucleotide of the mixture encodes a peptide having a target property. The polynucleotides of the invention present in the mixture in detectable, retrievable, and clonable amounts are expressed in a host organism for screening for the target activity. The invention features the ability to synthesize controlled random polynucleotides to produce a predetermined mixture of polynucleotides and to avoid synthesis of a stop codon by adjusting the proportions into which the synthesis pool is subdivided and by adjusting the proportions of activated nucleotides added at each coupling step. A polynucleotide encoding a peptide having a target property can be selected and sequenced to deduce the amino acid sequence of the peptide.Type: GrantFiled: December 6, 1996Date of Patent: August 4, 1998Assignee: Chiron CorporationInventor: H.
