Publication number: 20090051160Abstract: A socket for receiving a medical hose or tubing. The hose may be, for example, reinforced medical hose. The socket includes an internal conical feature which enters an end of the hose when the hose is inserted in the socket. The conical feature compresses the hose, and places the hose wall under radial compression, which tends to keep the hose retained in the socket, even during a high pressure application The compression creates a barrier seal between the hose lumen and the conical feature to prevent fluid from contacting the very end of the hose. As such, there is less longitudinal force attempting to push the hose out of the socket.Type: ApplicationFiled: June 19, 2008Publication date: February 26, 2009Applicant: ATRION MEDICAL PRODUCTS, INC.Inventor: Rowland W. Kanner

Publication number: 20080185298Abstract: An improved contact lens case which includes domes that are provided on hinged members. Preferably, the contact lens case is configured to efficiently utilize space and volume such that no more than 10 cc's of contact lens solution are required to disinfect contact lenses in the case. The hinged members are preferably non-planar which allows the domes to be provided on the hinged members, and allows the use of deep larger diameter, back-to-back cages on the stem, without having to resort to using more than 10 cc's of fluid to immerse contact lenses that are disposed on the domes, between each of the domes and a respective cage. Each of the hinged members has a cylindrically-curved shell form in which the axis of its curve is approximately parallel to the central axis of the central planar stem member.Type: ApplicationFiled: February 7, 2008Publication date: August 7, 2008Applicant: ATRION MEDICAL PRODUCTS, INC.Inventors: Rowland W.

Patent number: 7322999Abstract: A tissue punch which is configured to operate by utilizing a spring force to compress tissue between a rotatable cutter blade and a tissue piercing element. The tissue punch is configured such that once the spring force is applied, the cutter blade can be selectively rotated by the user. The rotation of the blade, assisted by the compression from the spring force, causes the cutter blade to cut through the tissue. Three different methods for creating an anastomosis for locating a bypass graft are disclosed. In each method, bypass graft material is installed on a tissue punch and then sutured. Depending on the method, the tissue is punched either before or after the suturing.Type: GrantFiled: January 20, 2004Date of Patent: January 29, 2008Assignee: Atrion Medical Products, Inc.Inventors: Rowland W. Kanner, Richard M. Davis

Patent number: 7070051Abstract: A needle counter device which utilizes an adhesive disposed in one or more, preferably V-shaped, troughs. The adhesive provides instant, strong grip upon contact, but also provides very low resistance to needle penetration (i.e., it is easy to stick a needle in the adhesive, but difficult to pull the needle out). The device includes a base and a lid, and opens and closes much like a book. Once the device is closed, the device tends to remain closed unless intentionally opened. A thin layer of adhesive may be provided on the inside of the lid, to retain used surgical blades, and a piece of resilient foam may also be provided for temporarily “parking” a suture needle. The sides of each trough are lined with structure which serves to prevent an accidentally laid surgical instrument from unintentionally contacting the adhesive. Numerical indices provide a quick visual, counting assist.Type: GrantFiled: December 10, 2004Date of Patent: July 4, 2006Assignee: Atrion Medical Products, Inc.Inventors: Rowland W. Kanner, Larry Lee Young

Patent number: 6739628Abstract: A frangible hose connector that has a knit line at the intended point of fracture, as opposed to a circumferential groove or notch. The knit line provides a break zone which has a lower tensile strength than that of the parent material, thereby providing that the connector is relatively easy to fracture. The connector also includes finger grips which makes breaking the connector easier. The finger grips provide that the connector is configured to be fractured via a twisting or torsion force, as opposed to a bending force. As such, the connector tends to break in a manner wherein fluid does not fling or spray. The connector is formed of plastic, and the knit line is created during the plastic injection molded process, wherein two mold fronts are “squared-up” and meet in the mold cavity to form the knit line.Type: GrantFiled: June 3, 2002Date of Patent: May 25, 2004Assignee: Atrion Medical Products, Inc.Inventors: Rowland W.

Patent number: 6248194Abstract: A novel fabricated tube construction includes a sleeve formed from a stock material and a plastic neck member which includes a shoulder. The sleeve has overlapping edges which are joined together to form an lap seam. The neck member shoulder includes a mounting portion which has at least one raised, plastic weld rib thereon. An end portion of the sleeve initially overlays the shoulder such that the lap seam of the sleeve overlays the raised weld rib on the mounting portion. As a result, a small void is formed between the lap seam and the mounting portion. When the sleeve and the shoulder are joined together, the raised, plastic weld rib on the mounting portion melts and flows into the void to fill and seal the void. A portion of the mounting portion also melts to form a seal between the shoulder and the sleeve. When the shoulder and the sleeve are joined together in this manner, a leak-proof seal or joint is formed around the entire periphery of the shoulder between the shoulder and the sleeve.Type: GrantFiled: June 29, 1995Date of Patent: June 19, 2001Assignee: Atrion Medical Products, Inc.Inventor: Rowland W.
