Patent number: 9700449Abstract: The present disclosure provides an inflatable weight control device that is implanted long-term with an endoscope in obese and bariatric human patients to promote early and prolonged satiety. The device includes a flexible member coupled to a valve body assembly and an elongated durable module residing within the flexible member. The flexible member is selectively inflated to form two bulbs with a central passageway extending through the bulbs and the valve body assembly. Once the bulbs are inflated, the device is retained within the patient's pyloric valve to form a gastric outlet obstruction wherein chyme accumulates and then is directed through the central passageway to reach the patient's duodenum. Due to its unique configuration, the implanted device reduces gastric outflow which results in early and prolonged satiety when the patient consumes normal-sized meals or food portions, thereby reducing food consumption and increasing the patient's weight loss.Type: GrantFiled: January 13, 2017Date of Patent: July 11, 2017Assignee: AGT Inc.Inventors: Gary Annunziata, Timothy Stippick

Patent number: 9358070Abstract: A medical device package includes an elongate tubular holder having a first and a second detachable tip, and a medical device positioned within a cavity and contained within the holder via the first and second detachable tips. The medical device has a self-shaping bias and is loaded in opposition to the bias via contact with an inner surface of the holder defining the cavity. The first and second detachable tips may include snap-off tips, such that upon detachment the cavity is opened for removing the medical device. Related methodology is disclosed.Type: GrantFiled: January 21, 2013Date of Patent: June 7, 2016Assignee: Cook Medical Technologies LLCInventors: Logan Michael Cage, Elizabeth Anne Theobald, Kurt J. Tekulve, Steve Harris, Ryan Koontz

Patent number: 9352117Abstract: An infusion catheter includes an elongate catheter body having a longitudinally extending fluid supply passage, and a plurality of stellate side ports for infusing a treatment fluid from the fluid supply passage into a body lumen of a passage. Each of the stellate side ports is defined by sets of at least three convergent leaves having an attached basal edge, a terminal tip, and first and second free edges extending between the attached basal edge and the terminal tip. Making an infusion catheter includes forming a plurality of stellate side ports in fluid communication with a fluid supply passage of an elongate catheter body, each of the stellate side ports being defined by a set of at least three convergent leaves, and setting an infusion length of the infusion catheter during the forming step via spacing the stellate side ports between proximal and distal ends of the elongate catheter body.Type: GrantFiled: September 26, 2011Date of Patent: May 31, 2016Assignee: Cook Medical Technologies LLCInventor: Therese J. O'Day

Patent number: 9345476Abstract: The present embodiments provide apparatus and methods suitable for coupling a graft member to tissue, closing a bodily opening, and the like. In one embodiment, a tacking device comprises a wire having first and second ends, and further having delivery and deployed states. In the contracted state, the wire comprises an elongated configuration that is substantially parallel to a central longitudinal axis. In the expanded state, the wire comprises a head region and a body region, the head region comprising at least one full turn having a first diameter, and the body region comprising at least two full turns having a second diameter, wherein the first diameter is greater than the second diameter. One or more of the tacking devices may be delivered using a laparoscopic, endoscopic or percutaneous approach.Type: GrantFiled: May 26, 2010Date of Patent: May 24, 2016Assignee: COOK MEDICAL TECHNOLOGIES LLCInventor: Vihar C. Surti

Patent number: 9308104Abstract: A stent removal device for removing or repositioning a stent from within a lumen is provided. The stent typically comprises at least one element arranged circumferentially about the stent. The stent removal device includes a tube positioned within the lumen proximate to the stent, wherein the tube is capable of receiving at least a portion of the stent. The stent removal device also includes a pusher positioned within the tube capable of engaging the stent and/or the element. The stent removal device further includes a hook positioned within the tube and including a hook member capable of engaging the element such that force applied to the hook causes the stent to purse string.Type: GrantFiled: October 24, 2005Date of Patent: April 12, 2016Assignee: Merit Medical Systems, Inc.Inventors: Pankaj Satasiya, Tony Alexander

Patent number: 9301778Abstract: A surgical instrument for use with a surgical portal apparatus includes an elongate shaft having proximal and distal ends and defining a longitudinal axis and a dilating member disposed at the distal end of the elongate shaft. The dilating member has a first longitudinal arc segment and a second longitudinal arc segment in diametrical opposed relation to the first longitudinal arc segment. The first and second longitudinal arc segments define respective first and second radii of curvature transverse to the longitudinal axis. The first and second radii of curvature decrease from proximal to distal to define a generally tapered configuration of the dilating member. The first radius of curvature is greater than the second radius of curvature at predefined longitudinal positions of the dilating member such that the first longitudinal arc segment extends distally beyond the second longitudinal segment to define a penetrating tip.Type: GrantFiled: January 20, 2015Date of Patent: April 5, 2016Assignee: Covidien LPInventor: Robert C. Smith

Patent number: 9301764Abstract: An occluding device for occluding fluid flow through a lumen of a body vessel. The device comprises a coil and fibers attached to the coil. The coil has about 5 to 60 grams of initial tension to facilitate the coil to fold when deployed. The fibers extend from the coil at a length.Type: GrantFiled: July 2, 2004Date of Patent: April 5, 2016Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Robert I. White, Jr., Thomas A. Osborne, Kurt J. Tekulve

Patent number: 9289233Abstract: A surgical access device includes a proximal housing having proximal and distal end portions, the distal end portion of the housing being configured and adapted to engage a proximal portion of a flexible wound retractor. The proximal housing can be provided with a plenum chamber being defined therein, the plenum chamber being in fluid communication with at least one nozzle. The nozzle is preferably configured to direct pressurized fluid in an axial direction from the plenum chamber into a central bore of the surgical access device to provide a constant gaseous seal around a surgical instrument inserted therethrough, while inhibiting a loss of pressurized fluid from the body cavity therethrough. The plenum chamber can be adapted and configured to receive pressurized fluid and conduct the pressurized fluid to the at least one nozzle.Type: GrantFiled: October 11, 2009Date of Patent: March 22, 2016Assignee: SurgiQuest, Inc.Inventors: Ralph Stearns, Kurt Azarbarzin, James R.
