Accordingly, the product has the economic advantage and good physical properties of natural latex, while having good biocompatibility so as to prevent various allergies and side effects from toxins. Also, by adding NBR, elasticity is imparted and flexibility is improved, and slippage is improved so that insertion in and removal from the body is made easy and damage to a mucous membrane from stickiness can be prevented. | 04-30-2015 |
20150141938 | TROCAR CANNULA WITH ATRAUMATIC TIP - A surgical access port is provided with a trocar cannula having a substantially rigid portion and an atraumatic distal tip. The atraumatic distal tip is substantially compliant relative to the rigid portion of the cannula. The trocar cannula provides unobstructed surgical access into a body cavity allowing the insertion and removal of surgical instruments through the trocar cannula and into the body cavity using a minimal sized incision or entryway. | 05-21-2015 |
20150320610 | Absorbent Medical Accessory - An absorbent medical accessory ensures that the skin around a medical tube remains dry. The accessory includes an upper pad having a top side, a bottom side and a perimeter edge extending between the top and bottom sides. The bottom side is comprised of an absorbent material. The upper pad has an opening extending through the top and bottom sides. A lower pad is coupled to the upper pad and has a top surface, a bottom surface and a peripheral edge extending between the top and bottom surfaces. The lower pad is comprised of an absorbent material. The lower pad has a hole extending through the top and bottom surfaces. The hole is alignable with the opening such that a medical tube is configured for being extended through each of the opening and the hole for retaining the medical tube against each of the upper and lower pads. | 11-12-2015 |

20150367554 | SEQUENTIAL BIAXIAL STRAIN OF SEMI-CRYSTALLINE TUBES - The present disclosure provides a processing method for a polymer material to create a medical device with improved mechanical properties. This method allows better tailoring of the material's mechanical properties, hence a device to withstand greater structural loads in vivo. The method comprises providing an extruded polymer tube having an initial diameter and an initial length along a longitudinal direction, and longitudinally, bi-directionally straining the extruded polymer tube in a mold from the initial length to an expanded or extended length. The mold comprises a plurality of stationary heating elements. After longitudinally straining the tube, it is radially expanding in the mold from the initial diameter to an expanded diameter. | 12-24-2015 |
20160038237 | SURGICAL CANNULAS AND METHODS OF MANUFACTURING SURGICAL CANNULAS - A cannula includes a bowl portion with at least one depression in its outer surface, a tube portion, and a plurality of welds located at the at least one depression and joining the bowl portion to the tube portion. The plurality of welds may be discrete welds spaced from one another along a circumferential direction of the cannula. The weld joining a cannula bowl portion and a tube portion may be spaced from the distal end of the bowl portion. Various exemplary embodiments further contemplate methods of manufacturing a cannula by welding a tube portion and a bowl portion. Welding may occur, for example, in at least one depression of the bowl portion to form discrete welds spaced from one another along a circumferential direction of the cannula. In another example, welding may occur at a location spaced from and proximal to a distal end of the bowl portion. | 02-11-2016 |
20160067384 | CATHETER SHAFT HAVING HIGH STRENGTH AND FLEXIBILITY - Elongated shaft for a catheter including a single layer biaxially oriented nonporous thermoplastic polymer tubular member having a Shore durometer hardness of less than about 75D is provided. Elongated shaft for a catheter prepared by a process is also provided. | 03-10-2016 |
20160100982 | ULTRASONIC VITRECTOMY NEEDLE - A needle for use with an ultrasonic handpiece for dissecting and aspirating vitreous tissue includes a cannula having a lumen extending from a port adjacent a cannula distal tip to a cannula proximal end. The cannula port has a cross-sectional area less than a cross-sectional area of the cannula lumen. A hub attached to the cannula proximal end attaches to the ultrasonic handpiece. A needle lumen is formed from the cannula port to a proximal end of the hub. A length of the needle lumen is approximately an odd quarter of a drive frequency wavelength of the ultrasonic handpiece and a cannula length measured from the cannula distal tip to a distal end of the hub is long enough to extend from an incision site across a posterior segment of an eye. | 04-14-2016 |
