  • Publication number: 20150005264
    Abstract: CA-IX levels are predictive of the probability that a cancer patient will respond favorably to cancer therapy involving administration of a hypoxia-activated prodrug. In a first aspect, the present invention provides a method for treating cancer comprising the steps of measuring CA-IX levels in a sample isolated from the patient, and administering a hypoxia-activated prodrug only if the CA-IX level measured is equal to or greater than about 30 pg/mL (e.g. 28.8 pg/mL) CA-IX protein in a serum sample, as may be measured, for example or without limitation, using an ELISA. In one embodiment, a HAP is administered if the measured CA-IX level is equal to or greater than about 75 pg/mL (e.g. 77.1 pg/mL) protein in a serum sample. Thus, in one embodiment, the CA-IX level is measured based on the amount of CA-IX protein in a serum sample.

  • Publication number: 20080108978
    Abstract: A drainage catheter is adapted to drain fluid from the body cavity through a body conduit and includes an elongate tube and a retention member disposed at the distal end of the elongate tube. The retention member is adapted for movement between a low-profile state facilitating insertion of the catheter and a high-profile state facilitating retention of the catheter in its operative position. A woven mesh forms at least a portion of one of the tube and the retention member. The woven mesh can be formed of filaments heat-settable so that the catheter automatically moves to the high-profile state. Insertion of the catheter can be facilitated using a stylet which can be removed after insertion to permit the catheter to automatically return to its high-profile state.

  • Publication number: 20070277921
    Abstract: A steerable kink resistant access device is provided having an elongated body and a steerable portion. The access sheath has an outside diameter sufficiently small so that it may be inserted into a body cavity or conduit. The access sheath typically has two internal lumen, a first lumen sized and configured as an access to a surgical site and a second lumen sized and configured to contain a tensioning device that, when acted upon, will deflect the steerable portion. The tensioning device may be directly or remotely attached to an actuation device that operates to control the tensioning and loosening of the tensioning device.

  • Publication number: 20070244426
    Abstract: A duckbill check valve and septum combination includes a hollow elastomeric body having an open proximal end, a closed distal end and a pair of opposed flat portions that form a distal edge. The distal edge includes a slit having a periphery that is smaller than the periphery of the instrument inserted therethrough. The slit provides a zero seal in the absence of an instrument and an instrument seal in the presence of an instrument. A shield including a tubular member and a plurality of blades protruding distally from the distal end of the tubular member may be placed inside the check valve and operates to center and guide the surgical instrument through the blades before expanding the slit of the check valve. An instrument inserted into the check valve stretches the distal portion of the duckbill valve to form a septum-like seal around the inserted instrument.

  • Publication number: 20070239108
    Abstract: A balloon trocar includes a cannula assembly including a cannula and an outer sleeve fitting over the cannula. The distal end of the outer sleeve is proximal to the distal end of the cannula. A balloon is coupled to a distal portion of the sleeve and a distal portion of the cannula. The outer surface of the cannula includes a plurality of longitudinal channels for transmitting gas or fluid to the balloon. A bolster having a gel pad at its distal portion is slidably mounted to the cannula assembly and may be locked in a desired position. In use, the trocar is inserted into an incision through a body wall and into a body cavity. The balloon is inflated and the cannula assembly pulled proximally against the incision while the bolster is slid distally to the body wall and locked in place to seal the incision with the compressed balloon.

  • Publication number: 20070225650
    Abstract: A stabilization seal is used with existing cannulas for forming a gas-tight seal with tissue in a body wall The stabilization seal includes a cylindrical inflatable elongate tube having a graduated wall-thickness that is thicker in a central region and thinner in a distal-end region. The tube includes a sealing cuff, having an inflation port, for sealing around a cannula. Application of inflation pressure greatly expands the distal-end region while the central region expands slightly. Another embodiment of a stabilization seal includes an inflatable thread that is used with a cannula having a helical channel on its outer surface. An inflatable tube is wound into the channel. A distal end of the tube includes a gas-tight seal and a proximal end of the tube includes an inflation port In the uninflated condition the nested tube is flush with the channel. Inflating the tube enlarges the cannula assembly.

  • Publication number: 20070225569
    Abstract: A surgical wound retractor is adapted to dilate a wound stretchable to a desired diameter, the retractor includes a first ring having a diameter greater than that desired for the wound and being adapted for disposition interiorly of the wound. A second ring has a diameter greater than that desired for the wound and is adapted for disposition exteriorly of the wound. A plurality of retraction elements are disposed in a generally cylindrical relationship to each other, between the first ring and the second ring. These elements extend through the wound to exert a radial retraction force on the wound which is dependent on the distance separating the first ring and the second ring Retraction elements, both distensible and non-distensible are contemplated with appropriate attachment means at the rings to provide for variations in the retraction force. With a suitable retraction sleeve, a third ring can be provided to form a circumferential retainer to vary the retraction force.

  • Publication number: 20070179526
    Abstract: A surgical clamp includes opposing jaws and a covering enhancing traction between the jaws and a body conduit. A multiplicity of fibers oriented to extend longitudinally between the clamp and conduit may be composed of filaments and either woven or non-woven to form a fabric. A variety of weaves are contemplated to provide different textures, each having its own traction characteristics. The nature of the weave can control characteristics such as smoothness, absorption, and texture. The fibers or filaments may be formed from any solid or semi-solid material, adding its own characteristics to the resulting fabric insert or clamp.

  • Publication number: 20070149859
    Abstract: An incrementally adjustable wound retractor, which provides access to a body cavity, includes an inner ring having a diameter greater than the desired diameter of the wound incision, an outer ring having an annular axis and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve disposed in a generally cylindrical form between the inner and outer rings. The outer ring includes first and second circular tubes spaced apart axially with each including a lumen having a rigid, noncompliant split hoop placed therein. The outer ring may be rolled over itself and around the annular axis to retract the sleeve with sufficient force to stretch the incision to the desired diameter. A gel cap seal may be coupled to the outer ring outside of the biological body to seal the opening produced by the wound retractor between the body cavity and outside the body cavity.

  • Publication number: 20070118167
    Abstract: The trocar system includes a cannula insertable through a body wall using an obturator having a distal tip. A traction tread disposed interiorly of the obturator inverts at the distal tip and extends proximally along the outer surface of the obturator or cannula. At the distal tip the tread can facilitate parting rather than cutting the tissue Along the outer surface, the tread can engage the tissue to pull it proximally along the advancing obturator. This produces counter forces which can result in a net proximal force facilitating distention of the abdominal wall and separation of the abdominal wall from internal organs The traction tread can be axially and/or radially continuous.
