US Patent:

8226552, Jul 24, 2012

Filed:

May 12, 2008

Appl. No.:

12/119414

Inventors:

Jeremy J. Albrecht - Ladera Ranch CA, US
Jennifer T. Ko - Rancho Santa Margarita CA, US
Gary M. Johnson - Mission Viejo CA, US

Kevin K. Dang - Garden Grove CA, US

Assignee:

Applied Medical Resources Corporation - Rancho Santa Margarita CA

International Classification:

A61B 1/32

US Classification:

600208

Abstract:

A surgical access device has a surgical retractor having a noncompliant outer ring with an annular axis, an inner ring, and a sleeve coupling the outer ring to the inner ring. The noncompliant outer ring is adapted to roll over itself around the annular axis to roll the sleeve around the outer ring to retract and seal an opening in a biological body wall. The access device may include a lid adapted for being coupled to the noncompliant outer ring of the surgical retractor. The outer ring of the surgical retractor has a cross-sectional shape that prohibits the lid from being partially or incorrectly coupled to the outer ring of the surgical retractor.

International Classification:

A61M 29/00

US Classification:

60410101, 60410307, 60416402

Abstract:

A trocar cannula assembly can have a retention mechanism for advanced fixation. The retention mechanism can include a first, or distal balloon, and a second or proximal balloon to retain the position of the trocar cannula assembly with respect to a body wall of a patient. An inlet can be fluidly coupled to the retention mechanism via a fluid conduit so that the balloons can be selectively inflated and deflated. The retention mechanism can be coupled to the cannula, forming an integrated cannula assembly, or the retention mechanism can be removably attached to the cannula. Where the retention mechanism is removably attached to the cannula, it can include a double layer inflatable member with an outer layer including the first and second balloons, and an inner layer for retaining the cannula.

International Classification:

A61B 1/32

US Classification:

600208, 600201

Abstract:

Embodiments of a surgical access port system that comprises a retractor that is adapted for being coupled to a cap and that is particularly useful in natural orifice surgery are described. The retractor comprises an outer ring, wherein the outer ring is configured to be disposed proximate the natural orifice of the patient and substantially surround the orifice; a tubular body; and a funnel segment extending between and coupling the outer ring and the tubular body, wherein the funnel segment provides a diametric reduction between the relatively large diameter of the outer ring and the relatively smaller diameter of the tubular body, which is sized to fit within a natural orifice with minimal distention of the orifice.

A61F 2/24

Abstract:

A knotless suture fastener installation system for securing medical devices such as cardiac implants. The knotless suture fasteners may be spring-biased so as to grip onto sutures passed therethrough. The system includes a fastener deployment tool with a proximal handle and a distal shaft to which a fastener cartridge attaches. A plurality of disposable cartridges are sequentially attached to the end of the deployment tool and used to secure the medical implant one fastener at a time. The deployment tool may also cut the sutures being fastened.

International Classification:

A61F 2/24

Abstract:

A hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a substantially non-expandable, non-compressible prosthetic valve member having a peripheral sealing ring and an expandable stent frame projecting from an inflow end, thereby enabling attachment to the annulus without sutures. The stent frame may be plastically-expandable and may have a thin fabric layer covering its entirety as well as secondary sealing structures around its periphery to prevent paravalvular leaking. Other sealing solutions include interactive steps at the time of valve implant to establish seals around the stent and especially between the stent and the sealing ring of the valve member.
