摘要:
A catheter (250, 272) is provided for uniform distribution of fluid medication within an anatomical region. One embodiment of the catheter (272) is comprised of an elongated, proximal tube (282) defining a lumen (283) and an elongated, distal tube (280) having a closed end (284). The distal tube (280) is constructed from a bio-absorbable material and also defines a lumen (281), which communicates with the lumen (283) of the proximal tube (282). Another embodiment of the catheter (250) is comprised of an elongate tubular catheter body (254) defining a lumen (268). A distal end (262) of the lumen is closed and a portion of the catheter body (254) includes a plurality of openings (266) thereby defining an infusion section of the catheter (250). A tubular sheath (252) is constructed from a porous material and is positioned over the infusion section. The tubular sheath (252) extends at least a length of the infusion section. The tubular sheath (252) and the catheter body (254) are configured such that fluid within the lumen (268) must pass through the tubular sheath (252) to exit the catheter (250).
摘要(中):
提供导管(250,272),用于在解剖区域内均匀分布流体药物。 导管(272)的一个实施例包括限定内腔(283)的细长近端管(282)和具有闭合端(284)的细长远侧管(280)。 远端管(280)由生物可吸收材料构成,并且还限定与近端管(282)的内腔(283)连通的管腔(281)。 导管(250)的另一实施例由限定内腔(268)的细长管状导管主体(254)组成。 管腔的远端(262)是封闭的并且导管主体(254)的一部分包括多个开口(266),由此限定了导管(250)的输注部分。 管状护套(252)由多孔材料制成并位于输注部分上方。 管状护套(252)延伸至少一段输注部分。 管状护套(252)和导管主体(254)被构造成使得腔(268)内的流体必须通过管状护套(252)以离开导管(250)。
