  • Patent number: 6951555
    Abstract: A catheter and method of use may include an aortic balloon catheter having an integral expandable/collapsible lumen. The catheter comprises a main catheter body having a either a single or a plurality of lumens extending therethrough, and further includes an expandable/collapsible lumen disposed thereabout and carried by the main catheter body. The expandable/collapsible lumen has a relatively large diameter when inflated with respect to the main catheter body, and is self-inflating by fluid pressure when the fluid flows therethrough. The large inflatable/collapsible lumen is attached at its distal end to the main catheter body and thus is carried therewith into a body vessel, and thus is also supported by the catheter body to avoid kinking. The present invention also achieves technical advantages as a catheter for insertion into any body vessel having a limited diameter and which is susceptible to trauma, such as a urethra.

  • Patent number: 6740029
    Abstract: Disclosed is a device for isolating a cardiac surgical site. The device comprises a first finger having a clinging accessory for attaching the first finger to a heart, a second finger having a clinging accessory for attaching the second finger to the heart, a first joint disposed on the first finger so that the first finger may rotate on a surface of the heart such that said rotation stretches a surgical site, a first stopper disposed on the first finger for preventing undesired rotation of the first finger to isolate the surgical site, and a link for coupling the first finger to the second finger. Several embodiments of the fingers and clinging accessories are disclosed. A guard is provided to protect sutures from the clinging accessory. The guard is equipped with a sprayer to wash the surgical site. Also disclosed is a method of isolating a cardiac surgical site.

  • Patent number: 6319244
    Abstract: A catheter (10, 38, 40, 50, 80, 90) having both a flexible (30) and a rigid reinforcement section (36). The catheter body (12) is comprised of an elastomeric material, such as silicone, having a resilient coil or spring member (30) within a fluid delivery lumen (20) along the proximal portion (14) thereof. The catheter is provided with a more rigid malleable reinforcement member (36) at the distal portion (16) thereof, also extending within the fluid delivery lumen (20) and positioned proximal the coil member (30) within the fluid delivery lumen (20). The rigid reinforced distal portion (16) of the catheter body helps the surgeon to hold the tip of the catheter more firmly, and makes insertion of the catheter tip into the body vessel easier. The more flexible support portion (30) at the proximal portion (14) of the elastomeric catheter body reinforces the catheter to prevent kinking, yet allows flexibility to facilitate the surgeon to move the proximal portion (14) of the catheter out of the surgical site.
