Publication number: 20070060888Abstract: An aspiration catheter comprises a catheter body having an aspiration lumen therethrough. The distal opening of the aspiration lumen can be modified in various ways or can have the addition of structure in order to disrupt sealing between the port and material being aspirated. Examples of modifications include slots, castellations, zig-zag features, and other geometries which resist sealing of aspirated material. Blades, rollers, vibrating elements, and other structures may be provided within or around the distal end of the aspiration lumen in order to dislodge and disrupt aspirated material which can seal against the opening.Type: ApplicationFiled: September 6, 2005Publication date: March 15, 2007Applicant: KERBEROS PROXIMAL SOLUTIONS, INC.Inventors: Thomas Goff, Michael Orth, Mark Yang, Hung Ha

Publication number: 20060106361Abstract: Devices and methods for delivering drugs and other therapeutic or diagnostic substances to desired locations within the bodies of human or non-human animal subjects. An implantable delivery device comprising a reservoir is initianlly attached to a deliver catheter or delivery tool and is introduced into the body and positioned at a desired site. A therapeutic or diagnostic substance is then introduced into the reservoir and the delivery catheter or deliver tool is then removed, leaving the implantable delivery device implanted within the body. The substance is then delivered from the reservoir at a rate that causes the desire diagnostic or therapeutic effect. Also provided are substance eluting stents that elute substance from a selected surface of the stent (e.g., the outer surface) but not from another surface of the stent (e.g., the inner surface).Type: ApplicationFiled: September 23, 2005Publication date: May 18, 2006Applicant: Acclarent, Inc.Inventors: Ketan Muni, Hung Ha, Joshua Makower, John Morriss, John Chang, William Facteau, Amrish Walke

Patent number: 6156054Abstract: The present invention provides a protective sheath assembly which combines the function of an introducer, the function of a protective sheath and the function of a sealing valve in an integrated assembly. The protective sheath assembly of the present invention preferably comprises a protective sheath, a strain-relief tubing, and a connecting member or a hub. These parts are mounted, removably or permanently, into an integral device. The protective sheath assembly can also be used in combination with an introducer such as a needle introducer. The protective sheath has a proximal end, a distal end, and an elongated hollow body defining a lumen along the longitudinal direction of the protective sheath. A hub is provided to secure the proximal end of the protective sheath to an introducer. The lumen of the protective sheath serves to accommodate and protect a balloon catheter, as well as seal around the catheter.Type: GrantFiled: August 4, 1999Date of Patent: December 5, 2000Assignee: Percusurge, Inc.Inventors: G.
