  • Patent number: 8623065
    Abstract: The invention is a stent-graft device having a support component with multiple turns of an undulating member where the undulations have a number of apexes. The graft component of the device is substantially coaxial with the support component and is attached to the support component so as to allow a number of the support component's apexes to move relative to the graft.

  • Publication number: 20130211189
    Abstract: A gastric band assembly has one or more bladders incorporated therein so that basal intra-band pressure in the band can be set higher than typical Green Zone basal intra-band pressures. The higher basal intra-band pressures equate to higher basal intra-luminal or contact pressures from 35 mmHg and above.

  • Publication number: 20130211188
    Abstract: A gastric band assembly has one or more bladders incorporated therein so that the distensibility of the gastric band assembly is increased. The distensibility relates to the relative strength with which the gastric band assembly with a bladder resists the application of additional band contact pressure. Distensibility is quantified by measuring the change in band contact dimension (e.g., diameter or area) versus the change in band contact pressure.

  • Patent number: 8323328
    Abstract: A stent-graft including a stent member having an inner surface and an outer surface, a generally tubular graft member and a coupling member that couples the stent member to the graft member. The coupling member, which is the preferred embodiment is in the form of a ribbon, covers only a portion of the inner or outer surface of the stent member and secures the stent member and graft member to one another. Alternatively, the coupling member can be described as interconnecting less than entirely the inner or outer surface of the graft member to the stent member. With this construction, regions of the stent member do not interfere with the coupling member. Shear stresses between the stent member and the coupling member and the risk of tearing the graft or coupling member or delamination therebetween may be reduced as compared to a fully enveloped stent member. This construction also provides improved flexibility and kink resistance.

  • Publication number: 20120245412
    Abstract: A gastric band assembly has one or more bladders incorporated therein to minimize or modulate changes in intra-band pressure in response to changes in stoma area and band stoma area. The balloon portion of the gastric band encircles stomach tissue thereby forming a band stoma area. With the bladders incorporated in the gastric band assembly, the affect that changes in band stoma area have on intra-band pressure are minimized so that the patient stays at or near the physician set intra-band pressure longer than with a gastric band alone.

  • Publication number: 20120197069
    Abstract: A bladder assembly is provided in order to maintain the pressure in the balloon portion of a gastric band in a range corresponding to a so-called Green Zone. Multiple bladders are connected by flexible tubing which is connected at a distal end to the balloon portion of a gastric band. The elastically expandable bladders provide fluid pressure on the balloon portion of the gastric band in order to maintain the intra-luminal pressure within a desired range over a prescribed fill volume.

  • Publication number: 20120010459
    Abstract: An elastic bladder is provided that is in constant fluid communication with the expandable balloon portion of a gastric band in order to automatically and continuously adjust the gastric band. The fluid pressure between the bladder and the balloon portion of the gastric band automatically and continuously adjusts so that there is no lasting pressure differential between the bladder and the expandable balloon. As the level of restriction imparted by the gastric band on the stomach of the patient changes, fluid from the bladder automatically and substantially instantaneously flows to or from the expandable balloon portion of the gastric band thereby maintaining neutral fluid pressure equilibrium between the bladder and the balloon and automatically adjusting the band to the correct level of restriction to keep the patient in the optimum zone for weight loss.

  • Patent number: 7976454
    Abstract: A cardiac harness for treating or preventing congestive heart failure is configured to be placed about at least a portion of a patient's heart so as to apply a mild compressive force on the heart. In one embodiment, the cardiac harness is configured so that the variation of load as a function of expansion through a selected range of expansion is represented generally in the form y=ax+b, and the value of “a” does not increase as the percent expansion increases.

  • Publication number: 20090234429
    Abstract: A self-expanding, self-restraining endoluminal prosthesis is configured to be compressible into a collapsed state, and restrained in the collapsed state by structures integrated with the stent, and without the use of external structure. Such restraining structures engage one another to hold the prosthesis in the collapsed state. Expansile elements of the prosthesis urge the prosthesis to automatically expand once released from the collapsed state. Thus, once the restraining structures, which hold the prosthesis in the collapsed state, are disengaged, the prosthesis automatically expands to a deployed state.

  • Patent number: 7572219
    Abstract: The apparatus includes and elongate body having a proximal portion and a distal portion. The body includes a cavity sized to contain a cardiac harness in a compacted configuration and also includes a plurality of elongate push rods movable with respect to the body. The cardiac harness is releasably connected to each of the push rods such that advancement of the push rods in a distal direction moves the harness from a compacted configuration, within the cavity, to an expanded configuration, outside the cavity. The apparatus also includes a releasing member for releasing the connections between the push rods and the harness upon actuation of the releasing member by a user.

  • Publication number: 20090188889
    Abstract: The invention is directed to an expandable stent for implantation in a body lumen, such as an artery, and a method for making it from a single length of tubing. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common axis and interconnected by one or more interconnective elements. The individual radially expandable cylindrical elements consist of ribbon-like material disposed in an undulating pattern. Portions of the expanded stent project outwardly into engagement with the vessel wall to more securely attach the stent.
