摘要: A surgical tool for use in initial placement of a gastrostomy device in a patient includes an obturator, a cannula and an outer flexible tubular member. A pointed end of the obturator and an adjacent dilator cooperate to incise a tract through the abdominal and stomach walls of the patient. The obturator is removed, leaving the cannula and outer tubular member in place. A deformable section of the flexible tubular member is expanded by movement of the cannula. The outwardly deformed section is then pulled up against the inner wall of the stomach wherein the thickness of the stomach and abdominal walls can be measured by use of visible scale indicia carried on the external surface of the flexible tubular member. Subsequent to the noted measurement, a guidewire or pull wire is passed through a lumen provided by the cannula. The guidewire is used for placing a gastrostomy device of suitable size in the incised tract.

摘要: An implant is provided with an open-celled silicone elastomer foam outer layer. The implant may be formed by compressively deforming beads mixed with liquid elastomer in a mold containing a preformed support structure. The elastomer is cured and the beads dissolved out. Infusion and sensor catheters covered with the foam provide improved transport rates and faster response.

摘要: Device includes a flexible, hollow tube portion having a resiliently deformable mushroom shape tip at the inner end thereof to retain the tube in the stomach or other viscera of a patient and provide an enlarged internal chamber for the mounting of a one-way flapper valve therein and the seating of the flapper valve against the inner end of the tube portion to prevent reflux of gastric contents while permitting the influx of fluids into the stomach or other viscera of the patient through the tube portion. A pair of oppositely extending, relatively short, flat wings are integrally molded on the outer end of the tube portion to make the tube portion self-retaining and flush up against the skin. The wings are relatively narrow in width, whereby the tube portion may be rotated a part turn to bring the wings into contact with different areas of the skin if irritation should occur. A plug is integrally molded on the outer end of one of the wings by a flexible membrane which permits the plug to be inserted into the tube at the outer end thereof and removed therefrom as desired.
摘要翻译: 装置包括柔性的中空管部分,其在其内端处具有可弹性变形的蘑菇形尖端,以将管保持在患者的胃或其他内脏中,并且提供用于在其中安装单向瓣阀的扩大的内部腔室 以及挡板阀抵靠管部的内端的位置,以防止胃内容物的回流,同时允许流体通过管部分流入患者的胃或其它内脏。 一对相对延伸的,相对较短的平的翼片一体地模制在管部分的外端上,以使管部自身保持并与皮肤齐平。 翼的宽度相对较窄,由此管部分可以转动一部分,以使得如果发生刺激,则翼部与皮肤的不同区域接触。 插塞通过柔性膜整体模制在一个翼的外端上,该柔性膜允许插塞在其外端被插入到管中并根据需要从其中移除。

摘要: Hard-tissue implants are provided that include a bulk implant, a face, pillars, and slots. The pillars are for implantation into a hard tissue. The slots are to be occupied by the hard tissue. The hard-tissue implant has a Young's modulus of elasticity of at least 10 GPa, has a ratio of the sum of (i) the volumes of the slots to (ii) the sum of the volumes of the pillars and the volumes of the slots of 0.40:1 to 0.90:1, does not comprise any part that is hollow, and does not comprise any non-pillar part extending to or beyond the distal ends of any of the pillars. Methods of making and using hard-tissue implants are also provided.

摘要: A gastrostomy device includes a tubular portion and an internal bolster having a radial wing secured to the tubular portion. The internal bolster is flexible and permits elastic deformation between a first orientation with the wing wrapped into a generally cylindrical configuration and a second orientation with the wing unfuried. A constraining member encases the internal bolster to retain the internal bolster in the first orientation and to cover at least a major portion of the wrapped wing. Removal of the casing permits the internal bolster to move from the first orientation to the second orientation. The internal bolster may be deployed by a ripcord, freeing the internal bolster into the patient' stomach and deploying the internal bolster to the second orientation. Alternatively, the internal bolster may be deployed by the constraining member being dissolved by the patient's bodily fluids located inside the patient's stomach.
