Publication number: 20060247576Abstract: A device suitable for delivering a fluid-based agent in a body lumen in a mammalian body comprises a housing including an elongated bore, and a delivery element. The delivery element includes a proximal portion, a distal portion preferably comprised of a superelastic material, and a wall. The wall defines (i) a fluid passage extending between the proximal portion and the distal portion, and (ii) a plurality of apertures in fluid communication with the fluid passage at the distal portion. The housing is selectively movable relative to the delivery element between a first position in which the distal portion is disposed in the bore, and a second position in which the distal portion is disposed exteriorly of the bore. The apertures contact the vessel wall in the second position to enable the agent to be delivered directly to the wall of the lumen.Type: ApplicationFiled: June 9, 2006Publication date: November 2, 2006Applicant: MEDTRONIC, INC.Inventor: Philippe Poncet

Patent number: 6799357Abstract: The manufacture of seamless tubes in which the process includes providing an assembly having a metal tube blank, and an elongate metal core of shape memory effect material which is surrounded and contacted by the tube blank with a minimal gap. The assembly is elongated by mechanical working thereof at an elevated temperature until the tube blank has been converted into a tube of desired dimensions. After the elongation step, the core is subjected to a treatment which results in the core being in a stretched condition throughout its length, and does not substantially stretch the tube. The core is removed from the tube, and subsequently subjected to drawing passes over a nondeformable mandrel thereby refining the precision of diametric and wall dimensions with improved ID and OD surface quality. There is also decoring and reinserting to improve final dimensions which results in the ability to fabricate smaller, longer tubes.Type: GrantFiled: September 5, 2002Date of Patent: October 5, 2004Assignee: Memry CorporationInventors: Neal Webb, Philippe Poncet, Ming H.

Patent number: 6113610Abstract: A surgical device for closing trocar incision sites and delivering sutures. The present invention is a needle assembly in which the needle is constructed of a spring-like material and initially housed within a sheath in a deformed condition. The needle can be easily exposed by sliding an actuator so as to release the constraining means and allow the needle to assume its undeformed condition. The needle assembly has few parts, allows a wide range for deflection of the needle, and the needle may be exposed with a relatively short stroke.Type: GrantFiled: October 5, 1998Date of Patent: September 5, 2000Assignee: Medtronic, Inc.Inventor: Philippe Poncet
