Patent number: 9936946Abstract: A suture passer includes a stylet and a cannula having an open distal end defining a cannula outer diameter. The stylet has a proximal segment configured for receipt within the cannula and including a suture retention notch, and a distal segment having an expanded outer diameter substantially matching the cannula outer diameter. The distal segment of the stylet terminates at a distal cutting edge. The suture passer includes a retracted position in which the proximal segment of the stylet is received within the cannula through the open distal end and a shoulder defining a transition between the proximal segment and the distal segment abuts the open distal end of the cannula, and an extended position in which the suture retention notch is distally disposed relative to the open distal end of the cannula.Type: GrantFiled: June 26, 2014Date of Patent: April 10, 2018Assignee: Cook Medical Technologies LLCInventors: Joshua Haines, Amro Kamel, Brian Feng, Jeff Melsheimer

Patent number: 9549834Abstract: A deployment device to deploy a prosthesis for interconnecting vessel portions of a body vessel is described herein. The device includes a support frame and an actuation member coupled to the support frame. The actuation member is movable between a first and a second position. A retaining member is movable between a closed and a open position. In the closed position, the retaining member forms a chamber to retain a length of a prosthesis in a compressed configuration. In the open position, the retaining member is positioned to allow the prosthesis to move to an expanded configuration. Movement of the actuation member to the second position causes movement of the retaining member to the open position. One or more retractable cuffs can be positioned over the ends of the prosthesis for selectively retaining the corresponding prosthesis ends in the compressed configuration.Type: GrantFiled: April 17, 2015Date of Patent: January 24, 2017Assignee: Cook Medical Technologies LLCInventors: Amro Kamel, Eugene E.

Patent number: 9492154Abstract: Devices and methods for retracting tissue, such as bowels and organs, within the body of a patient are generally disclosed. In particular, the present disclosure describes surgical retractors having a series of intersecting strands defining openings there between, wherein the openings are enlargeable by slidable passage of the strands relative to one another. The present disclosure also teaches surgical retractors having a frame that defines a central opening and a supporting structure extending across the central opening and defining a plurality of openings, wherein the frame extends through the openings. In some embodiments, a surgical retractor comprises a monolithic polymeric structure extending across the central opening defined by a frame. Other embodiments and methods are disclosed.Type: GrantFiled: July 9, 2015Date of Patent: November 15, 2016Assignee: Cook Medical Technologies LLCInventors: Jeffry S.

Patent number: 8613752Abstract: A surgical instrument and a method for using the instrument are provided. The instrument can include a tubular member. A grasper can extend within the tubular member. The grasper can have grasping members each with a distal body. An opening can be formed in an inner surface of each distal body. The grasping members can pivot between an open and a closed configuration to engage a body vessel or tissue. A cutting device can extend within the tubular member. The cutting device can have a cutting member with a cutting edge. The cutting member can be movable between a free and an engaged configuration to sever a body vessel or tissue. When the grasping members are in the closed configuration, the openings of the distal bodies can form a cavity to receive the cutting member to shield the cutting member during navigation within a body of a patient.Type: GrantFiled: April 21, 2011Date of Patent: December 24, 2013Assignee: Cook Medical Technologies LLCInventor: Amro Kamel

Publication number: 20130053861Abstract: A device is used for deploying a prosthesis to vessel portions of a body vessel. The device can include a retaining member and a sheath. The retaining member, such as clamps, is movable between closed and open positions. In the closed position, the retaining member compresses an intermediate segment of the prosthesis. In the open position, the retaining member is positioned away from the prosthesis to allow for expansion of the intermediate segment. The sheath compresses an outer segment of the prosthesis, where the outer segment is associated with a first or second outer end of the prosthesis. The sheath is removable from the outer segment to allow for expansion thereof when the retaining member is in the closed position. An actuation member is operable to move the retaining member between the closed and open positions. Clamps are pivotable in response to movement of the actuation member.Type: ApplicationFiled: August 26, 2011Publication date: February 28, 2013Applicant: Cook Medical Technologies LLCInventors: Donald F.

Publication number: 20120277586Abstract: A feeding tube for insertion into the jejunum of a patient. An elongated tubular member has a proximal portion, a distal portion, a lumen extending between the proximal and distal portions, and at least one aperture at the distal portion. The aperture is sized for passage of fluid material from the lumen into the jejunum. An inflatable balloon is disposed about a length of the elongated tubular member distal portion. The balloon is sized and configured such that upon inflation via water or saline inflation media, the balloon projects outwardly from the tubular member distal portion so as to be engageable with an interior wall of the body passageway. An echogenic material is disposed along the tubular member distal portion in conjunction with the balloon to provide an echogenic capability, so that the tubular member length is visible under ultrasound imaging.Type: ApplicationFiled: April 26, 2011Publication date: November 1, 2012Inventors: Christopher D.

Publication number: 20120265055Abstract: A tube for insertion into a body passageway of a patient includes a generally elongated tubular member having a proximal portion, a distal portion, a lumen extending between the proximal portion and the distal portion, and at least one aperture at the distal portion sized and positioned for passage of fluid material therethrough from the lumen to a target area in the body passageway. The tubular member is structured such that the distal portion is selectively movable between the generally elongated configuration and a shaped configuration. A length of the distal portion is provided with one or more echogenic members disposed therealong such that the distal portion length is visible under ultrasound visualization when in the shaped configuration.Type: ApplicationFiled: April 15, 2011Publication date: October 18, 2012Inventors: Jeffry S.
