  • Patent number: 10463395
    Abstract: Gas-tight seal assemblies for use during minimally invasive surgery include various aspects. A wiper seal includes a sealing portion and a surrounding flex portion. Upper and lower faces of the sealing portions are angled with reference to an inserted instrument, the upper face's angle being more acute with reference to the instrument's shaft than the lower face's angle. The flex portion is corrugated, support ribs are in one or more corrugation grooves, and the support ribs allow the groove to easily collapse but resist the groove widening. The support ribs also prevent the sealing portion from inverting. An instrument insertion guide is positioned over the sealing portion and moves laterally with the sealing portion. A latch piece removably secures the seal assembly to a cannula. An anti-inversion piece prevents the wiper seal from inverting when an instrument is withdrawn.

  • Patent number: 8968249
    Abstract: A seal assembly for use with an access device includes a seal housing defining a central longitudinal axis, an inner wall and an outer wall. The inner wall defines a longitudinal opening to permit passage of instrumentation through the seal housing. A gimbal mount is at least partially accommodated within a space defined between the inner wall and the outer wall of the seal housing. The gimbal mount includes a seal member defining an aperture for substantial sealed reception of a surgical instrument. The gimbal mount is adapted for angular movement relative to the central longitudinal axis upon angulation of the surgical instrument while substantially maintaining the sealed reception of the surgical instrument.

  • Patent number: 8932275
    Abstract: A surgical seal assembly, includes a seal housing defining a longitudinal housing axis and having a longitudinal opening therethrough, a seal having an inner seal portion defining a passage and being adapted to form a substantial seal about a surgical instrument disposed within the passage and a guide mounted to the seal housing. The guide has an inner guide portion proximal of the inner seal portion of the seal and spaced therefrom. The inner guide portion defines a channel adapted to generally direct the surgical instrument toward the inner seal portion of the seal upon entry of the surgical instrument within the longitudinal opening of the seal housing. The inner guide portion is relatively compliant to accommodate initial offset or angled entry of the surgical instrument.

  • Patent number: 8920378
    Abstract: When a hub (40) is in an initial position at which it is located on the front end side of an inner cavity of a shield (20), an inner needle (50) penetrates an outer needle (30) and protrudes from a leading end of the outer needle to the outside, and when the hub is in a retracted position at which it is located on the rear end side of the inner cavity of the shield, the inner needle is housed within the inner cavity of the shield. A first side hole (31) is formed in an outer circumferential face of the outer needle, and a second side hole (51) is formed in an outer circumferential face of the inner needle.

  • Patent number: 8827958
    Abstract: A sheath can include a sheath body and a sheath hub. The sheath body can have a generally flexible tubular structure, a proximal end, and a distal end. The sheath body can further define a longitudinal axis. The sheath hub can attach to the proximal end of the sheath body and define a longitudinal axis generally aligned with the axis of the sheath body. The sheath body and sheath hub can also form a central cavity along their respective axes. The sheath hub can include two plates: a flexible plate and a rigid plate. The rigid plate can have a relief generally centered on the sheath body's axis. Advantageously, the flexible plate and rigid plate can overlap to substantially seal the central cavity.

  • Patent number: 8753317
    Abstract: A medical instrument includes a housing with a passage through which a catheter is received. A valve body is mounted in the passage, and, as the catheter penetrates through the valve body, the valve body conforms to the outer wall of the catheter to maintain a fluid tight seal between the valve body and the catheter. When the valve body is unstressed before being mounted in the passage, the valve body has a first planar dimension and a second planar dimension that is less than the first planar dimension.

  • Patent number: 8702657
    Abstract: A seal assembly for reception of an elongated surgical instrument is provided which includes a body having at least one opening configured and dimensioned to permit entry of an elongated surgical instrument and defining a central longitudinal axis; a seal member formed of a resilient material and defining an aperture therein, the aperture being configured and dimensioned such that insertion of the surgical instrument into the aperture causes the resilient material defining the aperture to resiliently contact the outer surface of the surgical instrument in a substantially fluid tight manner; and a fabric layer juxtaposed relative to the resilient material. A coating may be applied to the seal member to reduce friction between the seal member and surgical instrumentation inserted therein. The coating is preferably a hydrocyclosiloxane membrane prepared by plasma polymerization process.

  • Patent number: 8690831
    Abstract: Devices and methods are provided for removing fluid from a surgical access device and/or from surgical instruments passed therethrough, and for preventing such fluid from accumulating. For example, in one embodiment, an exemplary device can include a body defining a working channel that is configured and sized to allow for passage of a surgical instrument therethrough. A number of seals can be disposed in the working channel so as to contact the inserted surgical instrument. One or more outlets can be oriented to direct gas, such as air or an insufflation gas, into the working channel so as to remove fluid on the seals, or other parts of the surgical access device, as well as the surgical instruments themselves. In some embodiments, constant flows of gases can be arranged to act as shields to help prevent fluid from accumulating on the surgical access device and/or surgical instruments.
