An oocytes or ovum retrieval device is disclosed. The device may include a retrieval catheter dimensioned for transvaginal insertion into a cervical canal and for advancing distally into a fallopian tube and the ampulla of a female mammal. The retrieval catheter may include one or more fluid delivery lumens having a fluid delivery port for delivering a flushing fluid into said fallopian tube, an at least one aspiration opening in fluid connection with an internal aspiration lumen of said retrieval catheter, wherein the size of the at least one aspiration opening is determined based on a size of oocytes or ovum.

An elongated medical instrument includes a base material part, and an outer layer part made of a resin provided on a surface of the base material part. An outer surface of the outer layer part is a substantially flat surface other than the presence of irregularly disposed recesses or protrusions.

A rapidly insertable central catheter (“RICC”) insertion assembly can include a RICC, an introducer needle, a coupler coupling the RICC and the introducer needle together, and a sheath-splitting means for splitting a sheath body of the introducer needle away from an access guidewire. The sheath-splitting means allows the access guidewire to escape from the sheath body and remain in a needle tract established with the introduce needle. The splitting of the sheath body by the sheath-splitting means can be initiated by withdrawing the sheath body by a pair of finger tabs extending from a sheath hub around the proximal portion of the sheath body, twisting the introducer needle or a needle hub around the proximal portion of the needle shaft, triggering one or more triggers disposed in the coupler housing, or pushing a catheter tip of the RICC into the sheath body.
