Patent number: 11241320Abstract: An endoluminal prosthesis system for a branched body lumen comprises a branch vessel prosthesis. The branch vessel prosthesis is deployable within a branch vessel body lumen and comprises a stent having a generally tubular body portion, a flareable proximal end portion, and a coupling portion disposed intermediate the body portion and the flareable portion. The coupling portion is more crush-resistant than the body portion. The flareable proximal end may be disposed within a fenestrated stent graft with coupling portion disposed in the fenestration of the fenestrated stent graft.Type: GrantFiled: June 8, 2020Date of Patent: February 8, 2022Assignee: Cook Medical Technologies LLCInventors: Darin G.

Publication number: 20200230372Abstract: A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.Type: ApplicationFiled: January 14, 2020Publication date: July 23, 2020Applicant: Cook Medical Technologies LLCInventors: Brian L.

Patent number: 10646698Abstract: In at least one embodiment of the present invention a balloon catheter is provided. The balloon catheter comprises a shaft having a lumen formed therethrough. Connected to the shaft is an inflatable balloon. The inflatable balloon has a balloon wall defining a balloon interior surface and a balloon exterior surface that is opposite the interior surface. In fluid communication with the balloon wall is the lumen for inflating the balloon to define an inflated state and for collapsing the balloon to define a deflated state. The balloon wall is textured in the deflated state such that the balloon interior surface is spatially registered with the balloon exterior surface. The balloon in the inflated state is tensioned to have a surface roughness substantially less than a surface roughness of the balloon in the deflated state.Type: GrantFiled: October 11, 2017Date of Patent: May 12, 2020Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: David G.

Patent number: 9174030Abstract: Balloon catheters, and methods of treatment therewith, are provided including an inflatable first balloon at least partially enclosed by an expandable second balloon that has holes. The annular space between the first balloon and the second balloon is configured to promote delivery of the fluid evenly through holes in the second balloon to avoid problems of underloading and/or overloading. Preferably, the annular space is in communication with the holes, and the annular space is configured to receive and then to release and distribute the fluid via the holes in a substantially uniform manner such that even amounts of fluid are released in the distal and proximal holes. The first balloon may have various configurations including being tapered relative to the second balloon. The second balloon may also be tapered accordingly. The device may also include raised portions disposed in the annular space and configured to define channels having various configurations.Type: GrantFiled: October 23, 2013Date of Patent: November 3, 2015Assignee: Cook Medical Technologies LLCInventor: Scott E.
