  • Patent number: 10766117
    Abstract: A retaining ring can be shaped by machining or lapping the bottom surface of the ring to form a shaped profile in the bottom surface. The bottom surface of the retaining ring can include flat, sloped and curved portions. The lapping can be performed using a machine that dedicated for use in lapping the bottom surface of retaining rings. During the lapping the ring can be permitted to rotate freely about an axis of the ring. The bottom surface of the retaining ring can have curved or flat portions.

  • Publication number: 20190110674
    Abstract: A surgical access device is configured to provide an access path via an elongated cannula so that a medical scope can be advanced into a surgical field within a patient. A housing of the surgical access device encloses a wipe assembly configured to clean a lens of the medical scope. An access passage having an axis can be defined within the housing, and the wipe assembly can be spaced from the access passage so that the medical scope is angled off of the access passage axis in order for the lens to engage the wipe assembly. Portions of the housing can define fulcrum surfaces about which the medical scope can be rotated in order to align the lens with the wipe assembly.

  • Publication number: 20190059713
    Abstract: A medical scope cleaning device is configured to receive a distal end of a medical scope, wipe debris from the scope, apply an anti-fog/cleaning solution, and warm the scope in preparation for inserting the scope into a patient for a medical procedure. The cleaning device includes a sponge assembly disposed within a cleaning chamber. The sponge assembly includes expansion spaces. As a scope is moved through the cleaning chamber, the scope radially compresses sponges and urge at least portions of the sponges into the expansion spaces. The sponges wipe the scope and apply the solution. A heating coil warms the solution within the cleaning chamber.

  • Publication number: 20140255986
    Abstract: An automated machine for handling and embedding tissue samples contained on microtome sectionable supports. The machine includes an input member configured to hold a plurality of the microtome sectionable supports prior to a tissue embedding operation. An output member is configured to hold a plurality of the microtome sectionable supports after the tissue embedding operation. A cooling unit is configured to hold at least one of the microtome sectionable supports during the tissue embedding operation. A motorized carrier assembly is mounted for movement and configured to hold at least one of the microtome sectionable supports. The carrier assembly moves the support from the input member to the cooling unit and, finally, to the output member. A dispensing device dispenses an embedding material onto the microtome sectionable support and at least one tissue sample carried by the microtome sectionable support during the embedding operation.

  • Publication number: 20140249374
    Abstract: A device for creating an operative space within a body lumen for the performance of a medical procedure, including a pressurizable, expandable balloon element insertable into the body lumen. The balloon element includes an interior space for receiving an inflation fluid. The device further includes an ingress valve coupled with the balloon element and insertable therewith into the body lumen. The ingress valve is capable of being opened to allow the interior space to be filled with the inflation fluid and closed to retain the inflation fluid in the interior space. The device may also include an egress valve coupled with the balloon element and insertable therewith into the body lumen. The egress valve is closed when the interior space is filled with the inflation fluid and is capable of being opened to allow the inflation fluid to vent from the interior space.

  • Patent number: 6884251
    Abstract: An anastomosis is performed using a flexible mounting structure mounted on the outside of at least one vessel. Fasteners extend through the vessel and are bent towards the incision to attach the flexible mounting structure to the vessel in a manner that controls the edge of the vessel adjacent to the incision. The mounting structures are oriented on each vessel so fasteners on one mounting structure interdigitate with fasteners on the other mounting structure at the location of contact between the vessels when the two vessels are brought together. This creates two complementary sinusoidal-shaped vessel edges with peaks of one edge being accommodated in the valleys of the other edge. The peak-to-valley orientation forms a sinusoidal-shaped joint which is leak free. The fasteners are spaced so proper pressure is applied to the tissue to promote healing without leaking. Furthermore, the fasteners are sized and shaped to properly engage the tissue and bend in a desired manner.

  • Patent number: 5891160
    Abstract: A one-piece fastener or staple includes a base that contacts tissue and a prong that extends through the tissue. A suture lead is anchored to the base and a needle is attached to the suture lead. A tool positions the fastener adjacent to the tissue, and is operated to drive the prong and the suture needle through the tissue. The tool includes a needle grabber that is operated to grab the needle and pull the needle out of the patient. Since the suture lead is attached to the fastener, a prosthesis can be placed on the suture lead and pushed down to the tissue. A cassette is releasably mounted on the tool and contains the fastener, the suture lead and the suture needle. Alternative forms of the anchor have sutures attached to a base at locations that are spaced apart from each other, and sutures associated with each of two adjacent anchors can be tied together or sutures associated with a single anchor can be tied together. A suture threadably connected to an anchor can be used as a running suture.
