Publication number: 20080097512Abstract: A complex medical balloon (12) has at least two sections (14, 16), each of which has a different compliance curve. A compliance curve measures expansion size at various pressures. Accordingly, at a given pressure, one balloon section of a complex balloon will experience greater expansion than another section.Type: ApplicationFiled: November 18, 2005Publication date: April 24, 2008Inventors: Scott Sidwell, Thomas Trotta

Publication number: 20070288053Abstract: A balloon dilatation catheter has a relatively stiff and strong proximal cannula made of a material such as for example metal hypotubing. The distal end of the catheter includes an inflatable medical device or balloon, an inflation lumen and a guidewire lumen. A transition assembly is positioned between the proximal cannula and the distal end section. This transition assembly has a stiffening member within a transition tube, and provides for a flexible transition between the two components of diverse stiffness, namely the proximal cannula and the flexible distal end portion. A proximal end of the stiffening member may float within a distal end of the proximal cannula, but the stiffening member distal end is affixed to the shaft. The dilatation catheter may have a rapid exchange configuration, and is generally used in conjunction with a guiding catheter.Type: ApplicationFiled: April 17, 2007Publication date: December 13, 2007Inventor: Thomas Trotta

Publication number: 20050086129Abstract: A cross-branding reservation and tracking system for disseminating travel information, making and booking travel arrangements, and tracking use thereof. Websites of travel agencies or non-travel related business affiliates are linked to a customized reservation and booking site at which information on various resorts and travel arrangements is presented in a cross-branded format. Reservations are booked through a centralized booking engine component of the customized site. Tracking functions audit and report on click-through activity originating from each affiliated site. Multiple affiliations through a single affiliated URL are also enabled.Type: ApplicationFiled: September 24, 2002Publication date: April 21, 2005Inventors: Pasquale Patullo, Thomas Trotta

Patent number: 6500148Abstract: Dilation balloons and catheters including same are provided. The balloons are fabricated of a material such as a nylon or a polyamide material, and they have an inflated, non-distended working profile as well as a stretched inflated profile which is achieved by applying pressure through a dilatation catheter or the like that is in excess of that needed to achieve the inflated, non-distended profile and which is adequate to effect dilatation or the like up to a maximum pre-bursting pressure application. The maximum pre-bursting size of the balloon can be tailored depending upon the needs of the particular balloon within a wide range of possible maximum pre-bursting sizes.Type: GrantFiled: July 18, 2000Date of Patent: December 31, 2002Assignee: Cordis CorporationInventors: Leonard Pinchuk, Robert S.

Patent number: 5620649Abstract: A balloon catheter comprises a flexible, elongated member, an inflatable balloon carried on the elongated member to define an inflated chamber within the balloon, and an inflation conduit extending along the member and communicating with the inflation chamber. The inflatable balloon, in turn, defines a wall which comprises at least three bonded layers. A first pair of the layers comprises a flexible plastic material which is typically a condensation polymer. A second of the layers comprises a flexible polymer which is typically a vinylic polymer which is covalently bonded to the first layers and positioned between them.Type: GrantFiled: October 11, 1995Date of Patent: April 15, 1997Assignee: Cordis CorporationInventor: Thomas Trotta

Patent number: 5613979Abstract: A balloon catheter having an inflatable balloon in which the outer surface of the inflatable balloon is surrounded by an elastomeric sleeve. The sleeve is attached throughout at least a majority of its area to the balloon outer surface to provide pin hole and abrasion resistance. Preferably, the inflatable balloon is made of a flexible material of less elasticity than the material of the elastomeric sleeve. Thus the balloon expands to a generally limited maximum transverse dimension, while the collapse of the balloon is facilitated by the elastomeric sleeve.Type: GrantFiled: November 1, 1993Date of Patent: March 25, 1997Assignee: Cordis CorporationInventors: Thomas Trotta, Jeffrey A. Johnson

Patent number: 5585057Abstract: Medical device tubing is prepared from a blended polymer which is a blend of polyetheramide having substantially no ester linkages together with either or both of a polyamide and a polyesteretheramide having a hardness of at least about Shore 70D. The resulting tubing has an exceptionally high ratio of burst strength to flexibility, and the blended polymer retards blooming of the tubing that is believed to result from migration of monomers to the surface of the tubing.Type: GrantFiled: July 17, 1995Date of Patent: December 17, 1996Assignee: Cordis CorporationInventor: Thomas Trotta

Patent number: 5342386Abstract: Catheters are provided which have multiple flexibilities along their shafts as well as high pressure capabilities throughout the length of the catheter. Included is a catheter body having a relatively high stiffness which is particularly well-suited for maximum pushability through a body cavity or vessel. Secured to the distal end portion of this catheter body is a thin-walled, flexible tube which exhibits low stiffness to thereby impart maximum flexibility to the distal or tip portion of the catheter. A medical device balloon or other distal end member such as an atraumatic tip is secured to the distal end portion of the connecting tube. In the preferred arrangement, the thin-walled, flexible tube had been constructed by proceeding with radial expansion method in order to impart characteristics of excellent flexibility and high burst strength to the thin-walled flexible tube and thus to the assembled catheter.Type: GrantFiled: October 26, 1992Date of Patent: August 30, 1994Assignee: Cordis CorporationInventor: Thomas Trotta

Patent number: 5279596Abstract: An intravascular catheter comprises a proximal portion and a distal portion. The proximal portion has greater torsional stiffness than the distal portion, while the distal portion has greater dependability than the proximal portion. In accordance with this invention the distal portion carries a helical wire support member embedded therein, the helical support member being essentially free of crossing wires, to provide kink-resistance upon bending to the distal portion.Type: GrantFiled: June 25, 1992Date of Patent: January 18, 1994Assignee: Cordis CorporationInventors: Javier E.
